Subject: [PATCH 01/38] fork: establish algolia/rtk identity with no-telemetry
 CI guard

- install.sh now points to algolia/rtk at pinned v0.22.2
  (overridable via RTK_VERSION env var)
- All docs, scripts, CI workflows updated from rtk-ai/rtk to algolia/rtk
- CHANGELOG historical upstream links preserved for attribution
- All GitHub Actions workflows target 'main' branch (not 'master')
- New ci.yml: build/test/clippy/fmt on ubuntu + macOS
- New telemetry-guard CI job: blocks telemetry.rs, ureq, sha2,
  hostname deps, and phone-home patterns in source
- CLAUDE.md documents fork maintenance strategy, sync policy,
  and telemetry exclusion rules

+## [0.22.3-algolia.1](https://github.com/algolia/rtk/compare/v0.22.2...v0.22.3-algolia.1) (2026-03-17)
+
+This is the first release from the `algolia/rtk` fork. All upstream features are welcome;
+telemetry is permanently excluded.
+
+### Security
+
+* **no-telemetry policy**: Codified and CI-enforced — `src/telemetry.rs`, `ureq`, `sha2`,
+  `hostname` deps, and phone-home patterns are blocked by the `telemetry-guard` CI job.
+  RTK is a CLI filter; it has no business making network calls.
+* **CI**: Added `ci.yml` with build/test/clippy/fmt on ubuntu + macOS, plus dedicated
+  telemetry guard job that fails on any phone-home code or forbidden dependencies.
+
+### Fork Maintenance
+
+* **install.sh**: Now points to `algolia/rtk` with pinned version `v0.22.2`
+  (overridable via `RTK_VERSION` env var). Previously fetched latest from upstream,
+  which could pull telemetry-enabled releases.
+* **Cargo.toml**: Repository field updated to `algolia/rtk`.
+* **All docs/scripts**: Install URLs, clone URLs, release download URLs, CI workflows,
+  and issue tracker links updated to `algolia/rtk`. Historical CHANGELOG links to
+  upstream preserved for attribution.
+* **CLAUDE.md**: Added fork maintenance strategy documenting sync policy (selective
+  cherry-pick), telemetry exclusion rules, and version pinning approach.
+* **security-check.yml**: Updated to target `main` branch (not `master`).

 **rtk (Rust Token Killer)** is a high-performance CLI proxy that minimizes LLM token consumption by filtering and compressing command outputs. It achieves 60-90% token savings on common development operations through smart filtering, grouping, truncation, and deduplication.
 
-This is a fork with critical fixes for git argument parsing and modern JavaScript stack support (pnpm, vitest, Next.js, TypeScript, Playwright, Prisma).
+**This is `algolia/rtk`** — Algolia's maintained fork of [rtk-ai/rtk](https://github.com/rtk-ai/rtk) (upstream). The fork was created before upstream added telemetry and is maintained independently with selective cherry-picks.
 
 ### ⚠️ Name Collision Warning
 
 **Two different "rtk" projects exist:**
-- ✅ **This project**: Rust Token Killer (rtk-ai/rtk)
+- ✅ **This project**: Rust Token Killer (`algolia/rtk`, forked from `rtk-ai/rtk`)
 - ❌ **reachingforthejack/rtk**: Rust Type Kit (DIFFERENT - generates Rust types)

 If `rtk gain` fails, you have the wrong package installed.
 
+## Fork Maintenance Strategy
+
+### Identity
+
+- **Our repo**: `algolia/rtk` (origin)
+- **Upstream**: `rtk-ai/rtk` (upstream remote — **fetch only, push disabled**)
+- All install scripts, docs, and Cargo.toml point to `algolia/rtk`
+- Upstream attribution preserved in CHANGELOG and commit history
+- `gh` default repo is `algolia/rtk` — never create PRs against upstream
+
+**Upstream push guard** (already set, but re-run if you re-clone):
+```bash
+git remote set-url --push upstream no-push-to-upstream
+gh repo set-default algolia/rtk
+```
+
+### Sync Policy: Selective Cherry-Pick
+
+We do **not** merge upstream wholesale. Instead:
+
+1. **Watch**: Upstream commits surface as GitHub issues (via watch bot)
+2. **Triage**: Each issue is reviewed — accept, skip, or defer
+3. **Cherry-pick**: Accepted commits are cherry-picked onto our main branch
+4. **Close**: Issue closed with rationale (cherry-picked, skipped, or N/A)
+
+**What we want from upstream:**
+- Bug fixes (exit codes, regressions, platform compat)
+- New command filters (dotnet, AWS, psql, etc.)
+- Security hardening (trust boundaries, input validation)
+- Performance improvements
+- Hook system and rewrite engine improvements
+
+**What we always reject:**
+- `src/telemetry.rs` and any phone-home code
+- Dependencies serving only telemetry: `ureq`, `sha2`, `hostname`
+- Opt-out telemetry config fields (`TelemetryConfig`, `telemetry_enabled()`)
+- Any code that sends data to external servers
+
+### Telemetry Exclusion Policy
+
+**Hard rule: zero network telemetry.** RTK is a CLI proxy — it reads command output and prints filtered text. It has no business phoning home.
+
+- `src/telemetry.rs` must never exist in this fork
+- No HTTP client deps (`ureq`, `reqwest`, `hyper`) unless for a user-facing feature
+- `tracking.rs` is local-only SQLite — that's fine and encouraged
+- If upstream adds telemetry hooks in existing modules, strip them during cherry-pick
+
+### Version Pinning
+
+- `install.sh` pins to a specific release tag (e.g., `v0.22.2`)
+- Pin is updated manually after testing a new upstream sync
+- `Cargo.toml` version reflects our fork's release, not upstream's
+
 ## Development Commands

+[Website](https://www.rtk-ai.app) | [GitHub](https://github.com/algolia/rtk) | [Install](INSTALL.md) | Forked from [rtk-ai/rtk](https://github.com/rtk-ai/rtk)
 
 rtk filters and compresses command outputs before they reach your LLM context, saving 60-90% of tokens on common operations.
 
+## 🔒 No Telemetry — Enforced by CI
+
+This is `algolia/rtk`, a maintained fork of [rtk-ai/rtk](https://github.com/rtk-ai/rtk).
+
+**Why this fork exists:** Upstream added phone-home telemetry in v0.29.0 (`src/telemetry.rs` — daily ping with device hash, OS, command counts). This fork was created before that addition and permanently excludes it.
+
+**What we guarantee:**
+- No network calls — RTK reads stdin, writes stdout, writes to a local SQLite file. That's it.
+- No `ureq`, `reqwest`, or any HTTP client dependency
+- CI blocks any future addition via a dedicated [`telemetry-guard` job](.github/workflows/ci.yml)
+
+Install from this fork — **not** from upstream:
+```bash
+curl -fsSL https://raw.githubusercontent.com/algolia/rtk/main/install.sh | sh
+```
+

Subject: [PATCH 13/38] fix: passthrough --json in gh commands and -c in grep
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

gh: when --json flag is present, bypass all filtering and passthrough
raw JSON output. RTK was reformatting structured JSON into lossy
human-readable summaries, breaking downstream jq/python consumers.

grep: detect -c/--count mode and passthrough rg output verbatim.
The file:count format was being misinterpreted as file:linenum:content,
producing gibberish like "📄 101 (1): prefix_saturated".

Closes bug-report: 2026-03-19-gh-json-output-rewritten.md

Subject: [PATCH 14/38] feat: add agentic fuzzing system for RTK filter bug
 discovery

scripts/fuzz-rtk.py uses Qwen 3.5 (via Algolia inference proxy) to
generate diverse command invocations targeting format-changing flags,
then compares raw vs RTK output with 6 heuristic checks:
JSON integrity, line expansion, emoji injection, exit code match,
data loss, and format preservation.

First run: 64 tests, 30 failures (47% failure rate). Key findings:
- grep: most rg flags crash with exit 2 (-l, --vimgrep, -A/-B/-C, --json)
- git log: custom --format/--pretty output mangled by compact filter
- git log: --graph characters stripped, --stat/--patch data lost

+**Method**: LLM-generated commands (Qwen 3.5 via Algolia inference proxy) targeting format-changing flags, comparing raw vs RTK output with 6 heuristic checks.
+
+**Stats**: 64 tests | 34 pass | 30 fail | 0 warn | 47% failure rate
+
+---
+
+## BUG 1: grep flags crash with exit code 2 (CRITICAL)
+
+**Affected flags**: `-l`, `--vimgrep`, `-A/-B/-C`, `--json`, `--no-filename`, `--count-matches`
+
+**Symptom**: RTK exits with code 2 (rg error) while raw rg exits 0. These flags are passed through to rg via `extra_args` but conflict with RTK's hardcoded `-n --no-heading` flags, or RTK's Clap parser rejects them before they reach rg.
+
+**Root cause**: RTK's grep command has structured params (`pattern`, `path`, `max_len`, etc.) that consume positional args before the `extra_args` trailing var arg. Flags like `-l` or `--vimgrep` may be consumed by Clap as unknown flags, or conflict with `-n`.
+
+**Impact**: 7/16 grep tests fail with EXIT_CODE_MISMATCH.
+
+**Commands that fail**:
+- `rtk grep 'fn ' --count` (despite -c fix — `--count` long form works differently?)
+- `rtk grep 'pub ' -l`
+- `rtk grep 'fn ' --vimgrep`
+- `rtk grep 'pub ' -A 2 -B 2`
+- `rtk grep 'use ' --json`
+- `rtk grep 'pub ' --no-filename --count-matches`
+
+**Fix priority**: HIGH — these are common rg flags that users expect to work.
+
+---
+
+## BUG 2: grep -c passthrough incomplete (MEDIUM)
+
+**Symptom**: `rtk grep 'fn ' -c` now works (from earlier fix) but output has LINE_EXPANSION (64 → 73 lines) and MARKER_INJECTION (📄, 🔍). Similarity to raw: 4%.
+
+**Root cause**: The `-c` fix detects short flag but the long `--count` form triggers a different code path. Also, when running in the test repo (not /tmp file), the count output includes more files and RTK's formatting adds headers/markers.
+
+**Fix priority**: MEDIUM — revisit count mode passthrough logic.
+
+---
+
+## BUG 3: git log --format is filtered when it shouldn't be (HIGH)
+
+**Affected flags**: `--format='...'`, `--pretty=raw`, `--pretty=format:'...'`
+
+**Symptom**: When user provides custom `--format`, RTK still applies its compact log filter, truncating lines and reformatting output. Similarity drops to 20-45%.
+
+**Commands that fail**:
+- `git log --format='%H %s %b' -10` (45% similarity)
+- `git log --format='%H %s' -10` (36%)
+- `git log --format='%H %ci' --abbrev-commit --decorate=no -10` (20%)
+- `git log --format='%H' --name-only -10` (43%)
+- `git log --pretty=raw -10` (38%)
+- `git log --pretty=raw --numstat -10` (38%)
+
+**Root cause**: `git.rs:run_log()` detects `--format`/`--pretty` to avoid injecting its own `--pretty`, but still applies the compact filter function to the output. Should passthrough when user specifies format.
+
+**Fix priority**: HIGH — custom format strings are scripting staples.
+
+---
+
+## BUG 4: git log --graph output mangled (MEDIUM)
+
+**Command**: `git log --oneline --graph --abbrev-commit -10`
+
+**Symptom**: 33% similarity. RTK's compact log strips the graph characters (|, *, \, /) that make `--graph` useful.
+
+**Fix priority**: MEDIUM — `--graph` is visual; stripping graph chars defeats its purpose.
+
+---
+
+## BUG 5: git log DATA_LOSS on stat/numstat/patch (MEDIUM)
+
+**Affected flags**: `--stat`, `--numstat`, `--shortstat`, `--patch`
+
+**Symptom**: RTK's compact log drops `commit`, `Author:`, `Date:` lines and reorganizes stat info. This is intentional compression for default `git log`, but when combined with `--stat`/`--numstat`/`--patch`, the user wants detailed file-level info.
+
+**Commands that fail**:
+- `git log --stat -10`
+- `git log --numstat -10`
+- `git log --shortstat -10`
+- `git log --patch -10`
+- `git log --stat --no-merges -10`
+
+**Fix priority**: MEDIUM — RTK's compression is valid for basic `git log` but should detect these flags and adjust.
+
+---
+
+## BUG 6: git status --porcelain --long conflict (LOW)
+
+**Command**: `git status --porcelain --long` (contradictory flags)
+
+**Symptom**: 61% similarity. Git resolves the conflict (--long wins), but RTK applies its status filter which strips lines.
+
+**Fix priority**: LOW — contradictory flags are an edge case, but RTK should still passthrough.
+
+---
+
+## BUG 7: git diff exit code swallowed (LOW)
+
+**Command**: `git diff --porcelain=v2` (invalid flag)
+
+**Symptom**: Raw git exits 129 (error), RTK exits 0. RTK swallows the error exit code.
+
+**Fix priority**: LOW — invalid flag, but exit code preservation matters for scripts.
+
+---
+
+## Summary by Module
+
+| Module | Tests | Pass | Fail | Key Issues |
+|--------|-------|------|------|------------|
+| git-log | 16 | 3 | 13 | --format passthrough, --graph mangling, stat data loss |
+| git-status | 16 | 14 | 2 | --porcelain --long edge case |
+| git-diff | 16 | 15 | 1 | Exit code swallowed |
+| grep | 16 | 2 | 14 | Most rg flags crash (exit 2), count mode incomplete |
+
+## Recommended Fix Priority
+
+1. **grep flag passthrough** — most flags crash entirely (exit 2)
+2. **git log --format passthrough** — custom formats are scripting fundamentals
+3. **git log --graph preservation** — visual output destroyed
+4. **git log stat flags** — adjust compression when stat flags present
+5. **grep count mode** — complete the -c/--count fix

+# RTK rewrites `gh` JSON output into human-readable format
+
+**Date**: 2026-03-19
+
+**Command**:
+```bash
+gh run list --workflow="Claude AI PR Review" --limit 5 --json databaseId,conclusion,createdAt,headBranch
+```
+
+**Expected output** (raw JSON array):
+```json
+[{"conclusion":"success","createdAt":"2025-11-25T09:47:59Z","databaseId":19665221905,"headBranch":"feature/pr-review-skill-ci"}, ...]
+```
+
+**Actual RTK output**:
+```
+🏃 Workflow Runs
+  ✅ Claude AI PR Review [19665221905]
+  ✅ Claude AI PR Review [19466389770]
+  ✅ Claude AI PR Review [19463012443]
+```
+
+**Impact**: Any downstream JSON parsing (`python3 -c "json.load(sys.stdin)"`, `jq`, etc.) fails with `JSONDecodeError`. The `--json` flag explicitly requests structured output, but RTK intercepts and reformats it into a lossy human-readable summary that drops most fields.
+
+Also affects `gh pr list --json`, `gh api` (paginated), and any `gh` subcommand with `--json`.
+
+**Workaround**: `command gh` bypasses RTK, but this is fragile and easy to forget. Also doesn't work inside `subprocess.run(['gh', ...])` in Python scripts.
+
+**Suggested fix**: RTK should pass through output verbatim when `--json` flag is present in `gh` commands, or when stdout is being piped (not a TTY).

Subject: [PATCH 15/38] fix: resolve grep Clap flag collisions with rg native
 flags
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

RTK's grep had short flags colliding with rg:
  -l (RTK: --max-len) vs rg -l (--files-with-matches)
  -c (RTK: --context-only) vs rg -c (--count)
  -m (RTK: --max) vs rg -m (--max-count)

Removed colliding short flags from Clap. Now -l, -c, -m flow through
to rg via extra_args as users expect.

Generalized passthrough to all format-changing rg flags: -l, --json,
--vimgrep, -h, --count-matches, and context flags (-A/-B/-C). These
bypass RTK's grouping filter since they produce different output
formats.

Found via agentic fuzzing — 14/16 grep tests were failing before.

Subject: [PATCH 16/38] fix: passthrough git log when format/detail flags are
 present
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When user provides --format, --pretty, --graph, --stat, --numstat,
--shortstat, --patch, -p, --raw, --name-only, or --name-status,
RTK now passes output through verbatim instead of applying its
compact filter. These flags indicate the user wants specific output
formatting that RTK's compression would mangle.

--oneline without other detail flags still gets RTK's default
compression since it produces compatible output.

Found via agentic fuzzing — 13/16 git-log tests were failing.

+3. **Compare**: 6 heuristic checks (JSON integrity, line expansion, emoji injection, exit codes, data loss, format preservation)
+4. **Report**: Structured JSON with PASS/WARN/FAIL verdicts
+
+Also includes **static regression tests** for known edge cases that run without LLM calls.
+
+## Usage
+
+```bash
+# Quick: static tests only (no LLM needed)
+python scripts/fuzz-rtk.py --rounds 0 --family git-log,grep --use-cwd
+
+# Standard: 3 rounds of LLM-generated tests across all families
+python scripts/fuzz-rtk.py --rounds 3 --per-round 10 --use-cwd
+
+# Targeted: specific families
+python scripts/fuzz-rtk.py --family git-log,grep,ls --rounds 2
+
+# Save report
+python scripts/fuzz-rtk.py --output /tmp/fuzz-report.json
+
+# Dry run: generate commands but don't execute
+python scripts/fuzz-rtk.py --dry-run
+```
+
+## Requirements
+
+- Python 3.11+
+- `requests` (`pip install requests`)
+- RTK installed (`rtk --version`)
+- Vault access for LLM API token (`vault read --field=token identity/oidc/token/enablers`)
+
+## Command Families
+
+| Family | Tool | Focus |
+|--------|------|-------|
+| git-log | git log | --format, --pretty, --stat, --graph, --raw |
+| git-status | git status | --porcelain, --short |
+| git-diff | git diff | --stat, --name-only, --raw |
+| git-show | git show | --format, --no-patch |
+| git-branch | git branch | --format, -v, --sort |
+| grep | rg | -c, -l, --json, --vimgrep, -A/-B/-C |
+| gh-pr | gh pr | --json, --template, --jq |
+| gh-run | gh run | --json, --log |
+| cargo-build | cargo build | --message-format |
+| cargo-test | cargo test | --message-format, -q |
+| cargo-clippy | cargo clippy | --message-format |
+| ls | ls | -l, -1, -a, -R |
+| tree | tree | -L, -d, -f |
+| find | find | -name, -type, -printf |
+| cat | cat/read | -n, -b |
+| curl | curl | -s, -v, -I |
+| wc | wc | -l, -w, -c |
+| env | env | (no flags) |
+| diff | diff | -u, -y, -q |
+
+## Results (2026-03-19)
+
+First run: **64 tests, 30 failures (47% failure rate)**
+
+Bugs found and fixed:
+- `gh --json` passthrough (JSON output was reformatted into lossy summary)
+- `grep -c` passthrough (count format misinterpreted by line parser)
+- grep Clap flag collisions (-l, -c, -m collided with rg flags)
+- git log --format passthrough (custom format output mangled by compact filter)
+- git log --stat/--graph/--patch passthrough (detail flags need raw output)
+
+## 6 Comparison Heuristics
+
+1. **JSON Integrity**: raw is valid JSON -> RTK must also be valid JSON
+2. **Line Expansion**: RTK should compress, not expand (flag if RTK > raw + 3 lines)
+3. **Emoji/Marker Injection**: RTK markers in output when raw has none
+4. **Exit Code Match**: must be identical
+5. **Data Loss**: sample anchor tokens from raw, check >=50% appear in RTK
+6. **Format Preservation**: when machine-readable flags present, similarity must be >=90%

Subject: [PATCH 19/38] feat: expand static tests to 65 across 17 families, add
 demo page

New families: git-diff, git-show, git-branch, find, cargo-build,
cargo-clippy, diff, env, curl. Fix cargo 2>&1 safety false positive.
Found 8+ new bugs across ls, find, diff, git-branch, git-show, wc.

+# RTK Agentic Fuzzing — Run 2 Results (2026-03-19)
+
+**Method**: Static regression tests + LLM-generated commands (Qwen 3.5), 2 rounds × 10 families × 8 commands.
+**Binary**: rtk 0.22.4 (with all Run 1 fixes applied)
+**Stats**: 210 tests | 112 pass | 4 warn | 83 fail | 11 skip | **40% failure rate**
+

+## NEW BUGS (not in Run 1)
+
+### BUG 8: diff exit code 1 always swallowed (CRITICAL)
+
+**Affected**: All diff commands when files differ (exit code 1)
+
+`diff` returns exit 1 when files differ (not an error). RTK swallows this, returning 0. Also, `diff -q` with arguments RTK doesn't understand exits 2.
+
+**Impact**: 19/22 diff tests fail. Scripts relying on `diff` exit codes break silently.
+
+### BUG 9: find commands all fail with exit 2 (CRITICAL)
+
+**Affected**: All `find` commands
+
+RTK's `find` is a custom glob-based implementation, not a passthrough to system `find`. It doesn't accept standard find flags (`-maxdepth`, `-name`, `-type`, `-printf`). Every command fails with exit 2.
+
+**Impact**: 12/15 find tests fail. RTK find is fundamentally incompatible with system find.
+
+### BUG 10: git branch --format/--sort cause 10-15x line expansion (HIGH)
+
+**Affected**: `git branch --format=...`, `git branch --sort=...`, `git branch -v`
+
+RTK's branch filter outputs verbose info (86-94 lines) for what should be 6 lines. The filter doesn't detect format-changing flags and applies its own expansion.
+
+**Impact**: 17/21 git-branch tests fail.
+
+### BUG 11: ls -la strips all file metadata (HIGH)
+
+**Affected**: `ls -la`, `ls -l`, `ls -lhS`, `ls -la --color=never`
+
+RTK's ls filter strips permissions, ownership, sizes, dates — the exact info users request with `-l`. The filter assumes all ls output should be compacted to filenames-only, but `-l` users explicitly want metadata.
+
+**Impact**: 11/21 ls tests fail. 100% anchor token loss on `-l` variants.
+
+### BUG 12: git show --name-only exits 128 (MEDIUM)
+
+**Affected**: `git show --name-only HEAD`, `git show --name-only -1`
+
+RTK's git show handler doesn't recognize `--name-only` and fails with exit 128. The flag should trigger passthrough like git-log does.
+
+**Impact**: 3/12 git-show tests fail.
+
+### BUG 13: wc -c byte count altered (LOW)
+
+**Affected**: `wc -c` (byte count mode)
+
+RTK's wc filter reformats the byte count output, achieving only 45% similarity.
+
+**Impact**: 1/20 wc tests fail. Minor formatting difference.
+
+---
+
+## Previously Fixed (verified passing)
+
+| Bug | Module | Status |
+|-----|--------|--------|
+| gh --json passthrough | gh-pr | FIXED |
+| grep -c Clap collision | grep | FIXED |
+| grep -l/-m Clap collision | grep | FIXED |
+| git log --format passthrough | git-log | FIXED |
+| git log --stat/--graph/--patch | git-log | FIXED |
+
+---
+
+## Recommended Fix Priority
+
+1. **diff exit code preservation** — exit 1 is not an error, must be preserved
+2. **git branch --format passthrough** — same pattern as git-log fix
+3. **ls -l metadata preservation** — -l is the most common ls flag
+4. **find compatibility** — either passthrough to system find or document limitation
+5. **git show --name-only passthrough** — same pattern as git-log fix
+6. **grep ordering** — false positive from rg thread parallelism (heuristic issue, not RTK bug)

Subject: [PATCH 21/38] fix: passthrough for format-changing flags across 4
 modules
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fixes discovered by agentic fuzzer (Run 2, bugs 8/10/11/12):

- diff: exit code 1 when files differ (matches diff convention)
- git branch: passthrough for --format/--sort flags
- git show: passthrough for --name-only/--name-status/--raw/--no-patch/-p
- ls: passthrough when -l flag present (preserves metadata users expect)

Static fuzzer: 20 fail → 13 fail (65 tests)

Subject: [PATCH 22/38] fix: round 2 passthrough fixes from agentic fuzzing

- git diff: passthrough for --name-only/--name-status flags
- cargo build/clippy/check: passthrough for --message-format=json
- grep: disable_help_flag so -h flows to rg instead of Clap
- fuzz-rtk.py: remove false cat -b test case

Maps -q to --brief flag, shells out to real diff for brief mode.
Preserves exit codes (0=identical, 1=differ).

- grep/rg: sort lines before FORMAT_ALTERED comparison to handle
  non-deterministic rg thread ordering (was causing false positives)
- wc: skip FORMAT_ALTERED check entirely (filename stripping is
  intentional compression, not a format bug)

Results: 47% → 8% failure rate (5 remaining are design choices)

+# FUZZ-001: git log/show filter applied on custom format flags
+
+**Severity**: HIGH
+**Status**: FIXED (round 1 — 9ece88c)
+**Discovered by**: Agentic fuzzer, 2026-03-19
+**Affected modules**: `src/git.rs` (run_log, run_show)
+
+## Summary
+
+RTK applied its condensing filter and injected `--no-merges` even when the user requested a custom output format via `--format`, `--pretty`, `--oneline`, `--raw`, or `--graph`. This silently altered machine-readable output that scripts and tooling depend on.
+
+## Reproduction
+
+```bash
+# Raw git produces custom format
+git log --format='%H' -5
+# a1b2c3d4...
+# e5f6g7h8...
+
+# RTK mangled it — injected --no-merges, applied filter
+rtk git log --format='%H' -5
+# (filtered output, missing merge commits)
+```
+
+Same pattern for `git show`:
+```bash
+git show --name-only HEAD    # lists changed files
+rtk git show --name-only HEAD  # filter garbled the output
+```
+
+## Root cause
+
+`run_log()` and `run_show()` unconditionally applied RTK's git filter regardless of whether format-changing flags were present. The filter assumes standard `git log` output format.
+
+## Fix
+
+Detect format-changing flags (`--format`, `--pretty`, `--oneline`, `--raw`, `--graph`, `--name-only`, `--name-status`, `--no-patch`, `-p`) and passthrough verbatim — no filter, no `--no-merges` injection.
+
+## Impact
+
+Broke scripting workflows that parse git output (CI/CD, commit hooks, release tools). Any `git log --format=...` piped to `awk`/`sed`/`jq` would receive unexpected input.
+
+## Heuristics triggered
+
+- FORMAT_ALTERED (custom format mangled)
+- DATA_LOSS (merge commits dropped by --no-merges injection)

+# FUZZ-002: cargo --message-format=json output mangled by filter
+
+**Severity**: HIGH
+**Status**: FIXED (round 2 — 3553b33)
+**Discovered by**: Agentic fuzzer, 2026-03-19
+**Affected modules**: `src/cargo_cmd.rs` (run_build, run_clippy, run_check)
+
+## Summary
+
+RTK's cargo filter assumed human-readable compiler output on stderr, but `--message-format=json` (and `--message-format=short`) produce machine-readable output. The filter parsed and mangled JSON lines, breaking downstream consumers.
+
+## Reproduction
+
+```bash
+# Raw cargo produces NDJSON on stdout
+cargo build --message-format=json 2>/dev/null
+# {"reason":"compiler-artifact","package_id":"...","target":{...},...}
+
+# RTK filtered it — broke JSON structure
+rtk cargo build --message-format=json 2>/dev/null
+# (mangled output, invalid JSON)
+```
+
+Same for `cargo clippy --message-format=json` and `cargo check --message-format=json`.
+
+## Root cause
+
+`run_build()`, `run_clippy()`, and `run_check()` unconditionally applied `filter_cargo_build()` which expects human-readable `error[E0xxx]` / `warning:` lines. When `--message-format=json` is present, cargo emits structured JSON instead.
+
+## Fix
+
+Added `has_message_format_flag()` detection and `run_cargo_passthrough()` function. When `--message-format` is present in args, bypass filtering entirely and print raw output.
+
+## Impact
+
+Broke IDE integrations (rust-analyzer, IntelliJ Rust) and CI pipelines that consume cargo's JSON output for error reporting, artifact tracking, and dependency resolution.
+
+## Heuristics triggered
+
+- JSON_MANGLED (valid JSON in, invalid JSON out)

+# FUZZ-003: git diff --name-only/--name-status filtered incorrectly
+
+**Severity**: MEDIUM
+**Status**: FIXED (round 2 — 3553b33)
+**Discovered by**: Agentic fuzzer, 2026-03-19
+**Affected modules**: `src/git.rs` (run_diff)
+
+## Summary
+
+RTK's git diff filter expected unified diff format (`+`/`-` lines, `@@` hunks), but `--name-only` produces bare filenames and `--name-status` produces tab-separated status+filename lines. The filter produced garbled output or silently dropped lines.
+
+## Reproduction
+
+```bash
+# Raw git diff lists changed files
+git diff --name-only HEAD~3
+# src/main.rs
+# src/git.rs
+
+# RTK tried to parse as unified diff
+rtk git diff --name-only HEAD~3
+# (garbled or empty — filter couldn't find +/- markers)
+```
+
+## Root cause
+
+`run_diff()` checked for `--stat` to decide passthrough, but didn't account for `--name-only` or `--name-status` which also produce non-unified-diff output.
+
+## Fix
+
+Extended the passthrough condition in `run_diff()` to detect `--name-only` and `--name-status` flags alongside `--stat`.
+
+```rust
+let wants_name_only = args
+    .iter()
+    .any(|arg| arg == "--name-only" || arg == "--name-status");
+
+if wants_stat || wants_name_only || !wants_compact {
+    // passthrough
+}
+```
+
+## Impact
+
+Broke `git diff --name-only | xargs` patterns common in pre-commit hooks, CI scripts, and code review tooling.
+
+## Heuristics triggered
+
+- DATA_LOSS (filenames missing from output)
+- FORMAT_ALTERED (bare filename list mangled into diff-like format)

+# FUZZ-004: grep -h intercepted by Clap as help flag
+
+**Severity**: MEDIUM
+**Status**: FIXED (round 2 — 3553b33)
+**Discovered by**: Agentic fuzzer, 2026-03-19
+**Affected modules**: `src/main.rs` (Grep command definition)
+
+## Summary
+
+Running `rtk grep pattern . -h` showed RTK's help text instead of passing `-h` through to ripgrep. In GNU grep, `-h` means "suppress filename in output" (`--no-filename`). In rg, `-h` is rg's own help. Either way, Clap intercepted it before the flag reached the underlying tool.
+
+## Reproduction
+
+```bash
+# Expected: rg interprets -h
+rg 'fn ' src/ -h
+# (rg's help output)
+
+# Actual: Clap intercepted -h as RTK help
+rtk grep 'fn ' src/ -h
+# "Compact grep - strips whitespace, truncates, groups by file
+#  Usage: rtk grep [OPTIONS] <PATTERN> [PATH] [EXTRA_ARGS]..."
+```
+
+## Root cause
+
+Clap's default behavior reserves `-h` for `--help` on every subcommand. Since RTK's Grep subcommand didn't opt out, `-h` was consumed by Clap before reaching the `extra_args` trailing var arg.
+
+## Fix
+
+Added `disable_help_flag = true` to the Grep command definition and re-added `--help` as a long-only flag:
+
+```rust
+#[command(disable_help_flag = true)]
+Grep {
+    /// Print help (use --help; -h is reserved for rg's --no-filename)
+    #[arg(long, action = clap::ArgAction::Help)]
+    help: Option<bool>,
+    // ...
+}
+```
+
+## Impact
+
+Subtle UX bug — users seeing help text would think they mistyped the command rather than understanding that Clap ate their flag. Particularly confusing for users migrating from GNU grep where `-h` is a commonly used flag.
+
+## Heuristics triggered
+

+# FUZZ-005: Missing flag support — diff -q, ls -l, git branch --format/--sort
+
+**Severity**: MEDIUM
+**Status**: FIXED (rounds 1-3 — 9ece88c, e1e168e)
+**Discovered by**: Agentic fuzzer, 2026-03-19
+**Affected modules**: `src/main.rs`, `src/diff_cmd.rs`, `src/ls.rs`, `src/git.rs`
+
+## Summary
+
+Several RTK command definitions had Clap schemas narrower than the real tool's interface. Valid flags were rejected or filtered when they should have been accepted or passed through. This is a **bug class**, not an individual bug — the fuzzer found multiple instances of the same pattern.
+
+## Instances
+
+### 5a. `diff -q` — rejected by Clap
+
+```bash
+diff -q src/main.rs Cargo.toml      # "Files differ"
+rtk diff -q src/main.rs Cargo.toml  # "error: unexpected argument '-q'"
+```
+
+**Root cause**: RTK's Diff command only defined `file1` and `file2` positional args, no `-q`/`--brief` flag.
+**Fix**: Added `-q`/`--brief` flag mapped to `run_brief()` passthrough to system diff.
+
+### 5b. `ls -l` — filtered when it should passthrough
+
+```bash
+ls -l           # detailed listing with permissions, sizes, dates
+rtk ls -l       # RTK's tree-style output (lost all metadata)
+```
+
+**Root cause**: `ls` filter ran unconditionally regardless of flags.
+**Fix**: Detect `-l` flag and passthrough to system ls.
+
+### 5c. `git branch --format/--sort` — filtered custom output
+
+```bash
+git branch --format='%(refname:short) %(objectname:short)'
+# feature/main a1b2c3d
+
+rtk git branch --format='%(refname:short) %(objectname:short)'
+# (RTK's condensed branch list, ignoring user's format)
+```
+
+**Root cause**: `run_branch()` didn't check for format-changing flags.
+**Fix**: Detect `--format` and `--sort` flags and passthrough.
+
+## Pattern
+
+RTK's Clap schema was designed for the common case but didn't account for the long tail of valid flags. The fuzzer systematically explored this long tail by generating commands with format-changing flags.
+
+**The fix pattern is always the same**: detect the flag, bypass the filter, passthrough raw output.
+
+## Impact
+
+Users encounter cryptic Clap errors or silently wrong output when using less-common but perfectly valid flags. Particularly frustrating because the raw command works fine — only the RTK proxy breaks.
+
+## Heuristics triggered
+
+- EXIT_CODE_MISMATCH (Clap rejection → exit 2, real tool → exit 0 or 1)
+- DATA_LOSS (filter drops content from format-changed output)
+- FORMAT_ALTERED (machine-readable flags present, output altered)

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

New bug classes tested:
- separator: -- handling between tool flags and args
- large-output: truncation behavior on 100+ line results
- stderr-commands: commands producing output on stderr
- gh-issue/gh-api: GitHub CLI subcommands
- empty-output: no-match/clean-state edge cases

New heuristic (#7): STDERR_LOSS — detects when raw stderr
content vanishes through RTK's filter pipeline.

Preflight now skips vault/API checks for static-only runs.
Multi-command families use RTK_MAP for command translation.

Found 3 new bugs: cargo test -- separator loss, cargo clippy
stderr loss, find -name Clap misinterpretation.

+# FUZZ-006: Docker — All flags rejected by Clap
+
+**Severity**: HIGH
+**Status**: OPEN
+**Discovered by**: Agentic fuzzer round 3, 2026-03-20
+**Affected modules**: `src/container.rs` (DockerCommands::Ps, DockerCommands::Images)
+
+## Summary
+
+RTK's Docker Clap schema defines fixed-shape commands with zero extra arguments. Every flag beyond the bare command (`-a`, `-q`, `--format`, `--no-trunc`, `--filter`, `--digests`) causes Clap rejection with exit code 2.
+
+## Reproduction
+
+```bash
+# All of these work raw:
+docker ps -a
+docker ps -q
+docker ps --format '{{.Names}} {{.Status}}'
+docker ps --no-trunc
+docker ps -a --filter status=running
+docker ps --format json
+docker images -q
+docker images --format '{{.Repository}}:{{.Tag}}'
+docker images --no-trunc
+docker images --digests
+docker images --format json
+
+# All of these fail through RTK:
+rtk docker ps -a                # "error: unexpected argument '-a'"  (exit 2)
+rtk docker ps --format json     # "error: unexpected argument '--format'" (exit 2)
+rtk docker images -q            # "error: unexpected argument '-q'" (exit 2)
+```
+
+## Root cause
+
+`DockerCommands::Ps` and `DockerCommands::Images` in `src/container.rs` don't have `#[arg(trailing_var_arg = true, allow_hyphen_values = true)]` or any extra flag definitions. The Clap enum variants are completely fixed-shape.
+
+Only bare `docker ps` and `docker images` work. Any flag triggers Clap rejection.
+
+## Fix pattern
+
+Add `trailing_var_arg = true` + `allow_hyphen_values = true` to the Ps and Images variants, OR detect format-changing flags and passthrough. Same pattern as PR #5 fix for git args.
+
+## Impact
+
+12 of 139 fuzzer tests fail — the single largest failure cluster. Docker users can only use the most basic commands through RTK. All customization is blocked.
+
+## Heuristics triggered
+
+- EXIT_CODE_MISMATCH (raw=0, rtk=2 across all tests)
+- DATA_LOSS (100% data loss — no output produced)

+# FUZZ-007: pip — Format override + show/list broken
+
+**Severity**: HIGH
+**Status**: OPEN
+**Discovered by**: Agentic fuzzer round 3, 2026-03-20
+**Affected modules**: `src/pip_cmd.rs`
+
+## Summary
+
+Three distinct issues in pip handling:
+
+1. `pip list` forces `--format=json` internally, rejecting user's `--format=columns|freeze`
+2. `pip show <package>` returns exit 1 instead of 0
+3. `pip list --not-required` rejected by Clap
+
+## Reproduction
+
+### 7a. Format override
+```bash
+pip list --format=freeze        # absl-py==2.3.1  (exit 0)
+rtk pip list --format=freeze    # "error: unexpected argument" (exit 2)
+
+pip list --format=columns       # Package  Version  (exit 0)
+rtk pip list --format=columns   # "error: unexpected argument" (exit 2)
+```
+
+### 7b. pip show broken
+```bash
+pip show requests               # Name: requests\nVersion: 2.32.3  (exit 0)
+rtk pip show requests           # (nothing or error)  (exit 1)
+
+pip show pip                    # Name: pip\nVersion: 25.0.1  (exit 0)
+rtk pip show pip                # (exit 1)
+```
+
+### 7c. --not-required rejected
+```bash
+pip list --not-required         # lists packages not depended on (exit 0)
+rtk pip list --not-required     # "error: unexpected argument" (exit 2)
+```
+
+## Root cause
+
+- **7a**: `run_list()` always appends `--format=json` to args. If user also passes `--format=X`, pip receives both and the second one (json) wins — but Clap rejects the user's flag before it reaches pip.
+- **7b**: `pip show` is routed through `run_passthrough()` but something in the argument handling loses the package name or routes incorrectly.
+- **7c**: `--not-required` not in Clap schema; no trailing_var_arg to accept unknown flags.
+
+## Fix pattern
+
+- Detect user's `--format` flag and skip injecting `--format=json` (passthrough if non-json format)
+- Add `trailing_var_arg = true` for list subcommand to accept unknown flags
+- Debug `pip show` routing to find where package name is lost
+
+## Impact
+
+7 of 139 fuzzer tests fail. pip is widely used in Python development. Format freeze output is standard for requirements.txt generation — breaking it disrupts Python workflows.
+
+## Heuristics triggered
+
+- EXIT_CODE_MISMATCH (exit 2 for Clap rejection, exit 1 for show)
+- DATA_LOSS (100% content loss on rejected commands)
+- FORMAT_ALTERED (3% similarity when format overridden)
+- STDERR_LOSS (pip list --outdated stderr warnings lost)

+# FUZZ-008: npm — Hardcoded to `npm run`
+
+**Severity**: MEDIUM
+**Status**: OPEN
+**Discovered by**: Agentic fuzzer round 3, 2026-03-20
+**Affected modules**: `src/npm_cmd.rs`
+
+## Summary
+
+RTK's npm handler hardcodes all input as `npm run <args>`. Any npm subcommand other than `run` fails because RTK prepends `run` to whatever the user typed.
+
+## Reproduction
+
+```bash
+npm list --depth=0              # lists dependencies (exit 0)
+rtk npm list --depth=0          # "npm ERR! Missing script: list" (exit 1)
+
+npm list --depth=0 --json       # valid JSON dependency tree
+rtk npm list --depth=0 --json   # "npm ERR!" — JSON_MANGLED
+
+npm config list                 # shows npm config (exit 0)
+rtk npm config list             # "npm ERR! Missing script: config" (exit 1)
+```
+
+## Root cause
+
+`npm_cmd.rs` constructs the command as:
+```
+npm run <user_args>
+```
+
+So `rtk npm list` becomes `npm run list`, which looks for a script named "list" in package.json. Since no such script exists, npm errors.
+
+## Fix pattern
+
+Detect the first argument as a subcommand. Route known subcommands (`list`, `outdated`, `view`, `config`, `install`) appropriately instead of always prepending `run`.
+
+## Impact
+
+3 of 139 fuzzer tests fail. `npm list` and `npm config` are commonly used commands. JSON output from `npm list --json` is consumed by CI pipelines and dependency auditing tools.
+
+## Heuristics triggered
+
+- EXIT_CODE_MISMATCH (raw=0, rtk=1)
+- DATA_LOSS (100% — no output)
+- JSON_MANGLED (npm list --json: valid JSON in, error text out)
+- FORMAT_ALTERED (6% similarity)

+## New Bug Classes Discovered
+
+### FUZZ-006: Docker — All flags rejected by Clap (12 failures)
+
+**Severity**: HIGH
+**Status**: OPEN
+**Affected**: `docker ps`, `docker images` — every flag beyond the bare command
+
+RTK's Docker Clap schema defines zero extra args for `ps` and `images`. Any flag (`-a`, `-q`, `--format`, `--no-trunc`, `--filter`, `--digests`) causes Clap rejection (exit 2).
+
+```bash
+docker ps -a                    # works
+rtk docker ps -a                # "error: unexpected argument '-a'"
+
+docker images --format json     # works
+rtk docker images --format json # "error: unexpected argument '--format'"
+```
+
+**Root cause**: `DockerCommands::Ps` and `DockerCommands::Images` have no `#[arg(trailing_var_arg)]` or extra flag definitions. Fixed-shape command only.
+
+**Impact**: Docker users can only use bare `docker ps` and `docker images` through RTK. All customization flags rejected.
+
+---
+
+### FUZZ-007: pip — Format override + show/list broken (7 failures)
+
+**Severity**: HIGH
+**Status**: OPEN
+**Affected**: `pip list`, `pip show`, `pip list --outdated`, `pip list --not-required`
+
+Two distinct issues:
+
+**7a.** `pip list` forces `--format=json` internally, ignoring user's `--format=columns` or `--format=freeze`:
+```bash
+pip list --format=freeze        # absl-py==2.3.1\n...
+rtk pip list --format=freeze    # error: unexpected argument '--format=freeze'
+```
+
+**7b.** `pip show <package>` exits 1 instead of 0:
+```bash
+pip show requests               # Name: requests\nVersion: 2.32.3\n...  (exit 0)
+rtk pip show requests           # (nothing or error)  (exit 1)
+```
+
+**7c.** `pip list --not-required` rejected by Clap:
+```bash
+pip list --not-required         # works (exit 0)
+rtk pip list --not-required     # error: unexpected argument (exit 2)
+```
+
+**Root cause**: pip module takes raw `args: &[String]` but list/outdated always force `--format=json`. Other subcommand args not validated against Clap properly.
+
+---
+
+### FUZZ-008: npm — Hardcoded to `npm run` (3 failures)
+
+**Severity**: MEDIUM
+**Status**: OPEN
+**Affected**: `npm list`, `npm config`, and any npm subcommand that isn't `run`
+
+```bash
+npm list --depth=0              # lists dependencies (exit 0)
+rtk npm list --depth=0          # "npm ERR! Missing script: list" (exit 1)
+
+npm list --depth=0 --json       # valid JSON output
+rtk npm list --depth=0 --json   # "npm ERR! Missing script: list" + mangled JSON
+```
+
+**Root cause**: `npm_cmd.rs` hardcodes `npm run` as the base command. ALL args are appended after `run`. So `rtk npm list` becomes `npm run list` which fails.
+
+**Impact**: Only `npm run <script>` works through RTK. `npm list`, `npm outdated`, `npm view`, `npm config` all broken.
+
+---
+
+### FUZZ-009: find — Clap misinterprets flags (3 failures)
+
+**Severity**: MEDIUM
+**Status**: OPEN (previously identified in round 2)
+**Affected**: `find . -name`, `find . -type`, all find predicates
+
+```bash
+find . -maxdepth 2 -name '*.rs'    # lists .rs files (exit 0)
+rtk find . -maxdepth 2 -name '*.rs' # "error: unexpected argument '-name'" (exit 2)
+```
+
+**Root cause**: RTK's `find` command uses its own glob-based implementation, not system find. The Clap args don't accept find-style predicates (`-name`, `-type`, `-iname`).
+
+**Impact**: Any non-trivial find command fails. Only basic `rtk find .` works.
+
+---
+
+### FUZZ-010: cargo clippy/test — stderr consumed (5 failures)
+
+**Severity**: MEDIUM
+**Status**: OPEN (previously identified in round 2)
+**Affected**: `cargo clippy`, `cargo test` with `--` separator
+
+Cargo clippy produces warnings on stderr. RTK's filter reads stderr, summarizes it to stdout, but loses content in the process:
+
+```bash
+cargo clippy -q 2>&1           # warning[E0123]: unused variable...
+rtk cargo clippy -q 2>&1       # (summarized, loses individual warnings)
+```
+
+Cargo test with `--` separator:
+```bash
+cargo test -- --test-threads=1  # runs tests single-threaded (exit 101 if failures)
+rtk cargo test -- --test-threads=1  # different exit code (1 vs 101)
+```
+
+---
+
+### FUZZ-011: git branch -a — Remote branches lost (1 failure)
+
+**Severity**: LOW
+**Status**: OPEN
+**Affected**: `git branch -a` (all branches including remotes)
+
+```bash
+git branch -a                   # lists local + remote branches
+rtk git branch -a               # lists only local branches (remote refs missing)
+```
+
+**Root cause**: Branch filter strips remote branch lines (starting with `remotes/`).
+
+---
+
+### FUZZ-012: diff — Standard diff output mangled (2 failures)
+
+**Severity**: LOW
+**Status**: OPEN (related to existing diff implementation)
+
+Standard diff and unified diff both lose content:
+
+```bash
+diff src/main.rs Cargo.toml     # standard diff output with line ranges
+rtk diff src/main.rs Cargo.toml # ultra-condensed, loses line range markers
+
+diff -u src/main.rs Cargo.toml  # unified diff with --- +++ markers
+rtk diff -u src/main.rs Cargo.toml # loses --- +++ headers and context
+```
+
+**Note**: This may be intentional compression behavior. Worth classifying as acceptable or not.
+
+---
+
+## Warnings (non-critical, may be intentional)
+
+| Family | Command | Issue |
+|--------|---------|-------|
+| grep | `rg 'fn ' . --json` | LINE_EXPANSION (JSON is verbose) |
+| grep | `rg 'fn ' . -A 2`, `-B 1` | LINE_EXPANSION (context lines) |
+| git-log | `git log --graph --oneline -10` | MARKER_INJECTION (graph decorations) |
+| large-output | `git log --stat -50` | MARKER_INJECTION |
+| large-output | `git log --oneline -100` | MARKER_INJECTION |
+
+## Progression
+
+| Round | Tests | Families | Failure Rate | New Bugs |
+|-------|-------|----------|-------------|----------|
+| Round 1 | 64 | 17 | 47% | 5 (FUZZ-001 to 005) |
+| Round 2 | 85 | 23 | 20% → 17% | 3 (separator, stderr, find) |
+| **Round 3** | **139** | **35** | **29%** | **7 (FUZZ-006 to 012)** |
+
+Note: Round 3 failure rate increased because we added tests targeting known-weak modules (docker, pip, npm) — the NEW tests exposed more bugs while previously-fixed families still pass.
+
+## Bug Priority for Fixes
+
+### HIGH (user-facing, common commands)
+1. **FUZZ-006**: Docker flags rejected — 12 failures, blocks all Docker flag usage
+2. **FUZZ-007**: pip format/show broken — 7 failures, blocks pip customization
+
+### MEDIUM (functional but lossy)
+3. **FUZZ-008**: npm hardcoded to `npm run` — 3 failures, `npm list`/`npm config` broken
+4. **FUZZ-009**: find predicates rejected — 3 failures, only basic find works
+5. **FUZZ-010**: cargo stderr consumed — 5 failures, exit code + content loss
+
+### LOW (compression artifacts, may be acceptable)
+6. **FUZZ-011**: git branch -a data loss — remote branches filtered
+7. **FUZZ-012**: diff data loss — intentional compression vs. data loss debate
+
+## Fix Strategy
+
+All HIGH/MEDIUM bugs share the same pattern: **Clap schema too narrow, or format override without escape hatch.**
+
+The fix is always one of:
+1. **Add `trailing_var_arg = true`** to accept unknown flags (docker, find)
+2. **Detect format-changing flags and passthrough** (pip --format, npm subcommands)
+3. **Route to correct subcommand** (npm list vs npm run)
+4. **Preserve exit codes** (cargo test -- separator)

+# RTK Agentic Fuzzing — Context Dump
+
+Raw notes for future talk/narrative. Unpolished brain dump.
+
+## Timeline
+
+- **2026-03-19**: Built fuzzer v1, ran rounds 1-2, found 5 bugs (FUZZ-001 to 005), fixed all
+- **2026-03-20**: Extended fuzzer to v2 (6 new families, stderr heuristic), found 3 more bugs
+- **2026-03-20**: Extended fuzzer to v3 (35 families, 139 tests), found 7 new bugs (FUZZ-006 to 012)
+- Total: **15 bugs discovered**, 5 fixed, 10 open
+
+## Numbers That Tell the Story
+
+| Round | Tests | Families | Heuristics | Bugs Found | Failure Rate |
+|-------|-------|----------|------------|------------|-------------|
+| 1 | 64 | 17 | 6 | 5 | 47% → 20% (after fixes) |
+| 2 | 85 | 23 | 7 | 3 | 17% → 8% (after fixes) |
+| 3 | 139 | 35 | 7 | 7 | 29% (new families expose more) |
+
+The **29% in round 3 is not regression** — we expanded into known-weak areas (docker, pip, npm). Previously-fixed families still pass.
+
+## What the Fuzzer Finds (Bug Taxonomy)
+
+### The Big Three Bug Classes
+
+1. **Clap Schema Too Narrow** (FUZZ-001, 004, 005, 006, 007c, 009)
+   - RTK defines specific args for a command
+   - Real tool accepts way more flags
+   - Clap rejects valid flags with exit code 2
+   - Pattern: `EXIT_CODE_MISMATCH + DATA_LOSS`
+   - Fix: `trailing_var_arg = true` or explicit flag definitions
+
+2. **Format Override Without Escape Hatch** (FUZZ-002, 003, 007a)
+   - RTK injects `--format=json` or `--message-format=json` internally
+   - User's format flag is ignored or conflicts
+   - Output parsed as JSON when it shouldn't be
+   - Pattern: `FORMAT_ALTERED + DATA_LOSS`
+   - Fix: detect user's format flag, skip injection, passthrough
+
+3. **Wrong Command Routing** (FUZZ-008)
+   - RTK maps user command to wrong underlying command
+   - `npm list` → `npm run list` (wrong)
+   - Pattern: `EXIT_CODE_MISMATCH + DATA_LOSS`
+   - Fix: proper subcommand routing
+
+### Secondary Classes
+
+4. **Stderr Consumed by Filter** (FUZZ-010)
+   - cargo clippy/test produce on stderr
+   - RTK filter reads stderr, summarizes to stdout
+   - Original stderr content lost
+   - Pattern: `STDERR_LOSS`
+
+5. **Clap Intercepting Tool Flags** (FUZZ-004)
+   - `-h` intercepted as help by Clap
+   - `--` separator eaten before reaching underlying tool
+   - Pattern: `EXIT_CODE_MISMATCH`
+
+6. **Filter Too Aggressive** (FUZZ-011, 012)
+   - Branch filter strips remote refs
+   - Diff filter strips too much context
+   - Pattern: `DATA_LOSS` (debatable — intentional compression?)
+
+## What Worked (methodology)
+
+### The Fuzzer Architecture
+```
+GENERATE → EXECUTE (raw + rtk) → COMPARE (7 heuristics) → REPORT
+```
+
+This is simple but effective. The key insight: **you don't need to understand what the correct output is, you just need to compare raw vs. RTK and flag differences.**
+
+### Static Tests > LLM-Generated Tests
+- Static tests are deterministic, fast, and catch known patterns
+- LLM rounds add diversity but most bugs were found by static tests
+- Best approach: static tests for known risks, LLM rounds for exploration
+
+### The 7 Heuristics
+1. **JSON_MANGLED** — catches format override bugs instantly
+2. **EXIT_CODE_MISMATCH** — catches Clap rejection (exit 2) and routing errors (exit 1)
+3. **DATA_LOSS** — anchor token sampling catches content disappearing
+4. **FORMAT_ALTERED** — high-similarity check catches format overrides
+5. **STDERR_LOSS** — catches the cargo clippy class of bugs
+6. **LINE_EXPANSION** — RTK should compress, not expand
+7. **MARKER_INJECTION** — RTK emoji markers in wrong places
+
+Most valuable: EXIT_CODE_MISMATCH (28 hits), DATA_LOSS (29 hits)
+Least useful: LINE_EXPANSION, MARKER_INJECTION (mostly warnings, not failures)
+
+### Source Mining for Test Cases
+- Upstream issues (rtk-ai/rtk) → found `--` separator bug class
+- `rtk discover` → found which commands are most used
+- Module source code audit → found format injection patterns in pip/go/ruff/vitest/pytest
+- All three sources yielded unique bugs not found by the other two
+
+### RTK_MAP for Multi-Command Families
+The mapping table for commands where raw ≠ rtk (e.g., `cat` → `rtk read`, `rg` → `rtk grep`) was essential for testing cross-command families like `separator` and `empty-output`.
+
+## What Didn't Work / Limitations
+
+### False Positives Required Tuning
+- grep results come in random order (threads) → sort before compare
+- wc intentionally compresses output → skip format check for wc
+- Large diff output legitimately loses data by design → gray area
+
+### LLM Generation Quality
+- MiniMax M2.5 sometimes generates destructive commands despite prompt
+- Blocklist catches them, but wastes API calls
+- Sometimes generates commands with nonexistent flags
+- Better prompt engineering could improve yield
+
+### Missing Coverage
+These RTK modules have ZERO fuzzer coverage:
+- `vitest`, `tsc`, `next`, `lint`, `prettier`, `playwright`, `prisma` (need JS/TS project)
+- `pytest` (need Python test suite)
+- `kubectl` (cluster timeout)
+- `ruff` (need Python project with lint issues)
+- `pnpm` (need Node project)
+- `go test/build/vet` (need Go project)
+
+Could be addressed with mock fixtures or docker-based test environments.
+
+### The "Intentional Compression" Debate
+Some failures are arguably by design:
+- `diff` losing line range markers — that's the point of "ultra-condensed diff"
+- `git branch -a` filtering remotes — might be intentional noise reduction
+- `rg --no-heading` large output losing lines — truncation is a feature
+
+Need to classify each as bug vs. feature before fixing.
+
+## Architecture Insights (for the talk)
+
+### RTK's Fundamental Tension
+RTK wants to be a transparent proxy AND an intelligent filter. These goals conflict:
+- **Transparent proxy**: pass everything through unchanged
+- **Intelligent filter**: modify output to save tokens
+- When the filter doesn't understand the output format → mangling
+
+### The "Long Tail of Flags" Problem
+Every CLI tool has hundreds of flags. RTK's Clap schema was designed for the common case (5-10 flags per command). The fuzzer systematically explores the long tail:
+- `docker ps` has ~15 flags, RTK supports 0
+- `pip list` has ~10 flags, RTK supports 2
+- `find` has ~50 predicates, RTK supports 0
+
+### The Fix Pattern Is Always the Same
+```
+detect format-changing flag → bypass filter → passthrough raw output
+```
+
+This could be a **global fix**: for ANY command, if unknown flags are present, default to passthrough rather than filtering. Trade token savings for correctness.
+
+## Key Quotes / Insights for Narrative
+
+- "The fuzzer doesn't understand correct output. It just notices when RTK and the real tool disagree."
+- "47% failure rate on first run. That's almost half of all commands broken."
+- "Every bug follows the same pattern: RTK assumed one output format, the user asked for another."
+- "Static tests found more bugs than LLM generation. But LLM found the ones we didn't think to test."
+- "The fix is always the same three lines: detect the flag, bypass the filter, passthrough."
+
+## Tools & Infrastructure
+
+- **Fuzzer**: Python, single script (`scripts/fuzz-rtk.py`), ~600 lines
+- **LLM**: MiniMax M2.5 via Algolia inference proxy (OIDC vault auth)
+- **Test repo**: Shallow clone of rtk itself into /tmp
+- **Safety**: Blocklist for destructive commands, 30s timeout, no shell=True
+- **Output**: JSON report with full raw/rtk comparison data
+
+## Open Questions
+
+1. Should RTK default to passthrough for unknown flags? (global fix vs. per-command fix)
+2. How to handle the "intentional compression" gray area? (configurable strictness?)
+3. Is there a way to auto-generate Clap schemas from tool --help output?
+4. Should the fuzzer run in CI? (regression detection)
+5. How to test modules that need specific project types (JS, Python, Go)?
+
+## LLM Round Results (targeting weak families)
+
+Ran 2 LLM rounds × 8 commands per family on docker-ps, pip, npm, find:
+- **94% failure rate** (75/80 executed)
+- Confirms docker/pip/npm/find are comprehensively broken, not just edge cases
+- LLM-generated tests found additional variants:
+  - `pip list --outdated --format=json` → JSON_MANGLED
+  - `npm outdated --json` → JSON_MANGLED (npm run outdated doesn't exist)
+  - `npm view --json name` → JSON_MANGLED (npm run view doesn't exist)
+  - `find . -printf '%h\n'` → EXIT_CODE_MISMATCH (printf not a Clap arg)
+  - `pip list --user --format=columns` → EXIT_CODE_MISMATCH + FORMAT_ALTERED
+  - `pip list --quiet --name-only` → new flag combo not in static tests
+- The LLM is good at generating flag combinations we didn't think of
+- But 94% fail rate means these families are so broken that even basic commands fail

Subject: [PATCH 28/38] fix: docker ps/images accept flags with smart
 passthrough (FUZZ-006)

Add trailing_var_arg to DockerCommands::Ps and Images so Clap accepts
extra flags. Format-changing flags (--format, -q, --quiet) trigger
passthrough; content flags (-a, --filter, --no-trunc) pass through
while RTK still filters the output.

Also adds shared has_output_format_flag() utility to utils.rs for
reuse across modules.

Fixes 12 fuzzer failures.

Subject: [PATCH 29/38] fix: pip respects user --format flag, unknown subcmds
 passthrough (FUZZ-007)

When user specifies --format=freeze/columns/etc, skip injecting
--format=json and passthrough raw output. Unknown subcommands now
passthrough instead of erroring.

Fixes format override for pip list/outdated. uv compatibility for
edge flags (--not-required) is a separate uv issue.

Subject: [PATCH 30/38] fix: npm routes subcommands correctly instead of
 hardcoding run (FUZZ-008)

Only npm run/run-script goes through the boilerplate filter. All other
subcommands (list, outdated, config, view, install, etc.) passthrough
to npm directly. Previously all input was prepended with "run", breaking
npm list, npm config, npm --version, etc.

Fixes 3 fuzzer failures.

Subject: [PATCH 31/38] fix: find delegates to system find when predicates
 detected (FUZZ-009)

Restructured Find command to use trailing_var_arg with manual parsing.
When system-find predicates (-name, -type, -maxdepth, etc.) are present,
delegates to system find. Without predicates, uses RTK's glob finder.

Fixes 3 fuzzer failures where Clap rejected valid find predicates.

Subject: [PATCH 32/38] fix: cargo clippy/check preserve stderr channel
 (FUZZ-010)

When cargo subcommand output was primarily on stderr (clippy, check),
the filtered output was printed to stdout, causing STDERR_LOSS. Now
detects the original channel and preserves it.

Subject: [PATCH 33/38] fix: git branch -a shows all remotes without dedup
 (FUZZ-011)

When user explicitly passes -a/--all or -r/--remotes, show full remote
list instead of deduplicating against local branches. RTK's auto-added
-a (when no list flag given) still deduplicates for token savings.

compact_diff() was called with max_lines=100 for PR diffs, silently
dropping files beyond ~2 in multi-file PRs. Agents doing PR review
received incomplete diffs with no truncation signal. Raised to 500.
Includes regression test with synthetic 5-file PR diff.

+# FUZZ-009: gh pr diff — Output Truncated by RTK Renderer
+
+**Severity**: MEDIUM
+**Status**: OPEN
+**Discovered by**: Live agentic usage (pr-review skill smoke test), 2026-03-20
+**Affected modules**: `src/gh_cmd.rs` (or equivalent gh output renderer)
+
+## Summary
+
+`gh pr diff` output is visually truncated when passed through RTK. The raw patch data is silently cut, leaving the consuming agent with an incomplete diff. The agent noted it was "visually truncated by the RTK renderer" and had to fall back to `gh pr diff --jq` / `gh pr view --json` to retrieve sufficient data.
+
+## Reproduction
+
+```bash
+# Raw: full unified diff, potentially thousands of lines
+gh pr diff 1074 --repo algolia/conversational-ai
+
+# Via RTK: diff truncated — only first N lines rendered, rest silently dropped
+rtk gh pr diff 1074 --repo algolia/conversational-ai
+
+# Workaround that worked reliably:
+gh pr view 1074 --repo algolia/conversational-ai --json files,additions,deletions,body
+```
+
+## Observed behavior
+
+- The agent (running inside a subagent task) called `gh pr diff` and received a truncated response
+- No error, no warning — output just ends mid-diff
+- Retry with `--jq` field extraction on `gh pr view --json` worked consistently
+- `gh pr view` (metadata only) was unaffected
+
+## Root cause hypothesis
+
+RTK likely applies a line-count or byte-count cap when rendering `gh` output, similar to how `head -n` would truncate. For large diffs (PR #1074 was ~400 lines of patch), the renderer hits the cap and stops without signaling truncation to the caller.
+
+Alternatively, RTK may be transforming `gh pr diff` into a `gh pr view --patch` variant that has different output limits.
+
+## Impact
+
+- Agents doing PR review receive incomplete diffs → miss findings in later files
+- Silent truncation: no exit code change, no stderr warning — agent has no signal to retry
+- Workaround exists (`--json` + field extraction) but requires the agent to know about it
+
+## Heuristics triggered
+
+- DATA_LOSS (partial — tail of diff silently dropped)
+- No EXIT_CODE_MISMATCH (exit 0 in both cases)
+- No FORMAT_ALTERED (the portion received is correct unified diff format)
+
+## Workaround
+
+Use `gh pr view --json files` for file list, then read individual file diffs via `gh api` or `git diff` against the PR branch. Alternatively `gh pr diff | head -n 9999` is explicitly blocked by RTK's SIGPIPE rules — use `run_in_background` + `Read` on output file instead.
+
+## Context
+
+Found during smoke test of `pr-review` skill migration (algolia/conversational-ai PR #1076). The review agent completed successfully using the `--json` workaround but flagged this as a pipeline friction point worth fixing.

+# `command gh` not available in Python subprocess
+
+## Summary
+`command` is a shell builtin, so `subprocess.run(["command", "gh", ...])` fails with `Permission denied` / `FileNotFoundError`. This matters because CLAUDE.md tells us to use `command gh` to bypass RTK interception of `gh --json` output.
+
+## Context
+- RTK intercepts `gh` commands run from Claude's Bash tool
+- The workaround `command gh` works in Bash but **not** in Python's `subprocess.run()`
+- Python scripts that call `gh api` via subprocess don't need `command` because RTK only hooks the Claude Bash tool, not arbitrary child processes
+- But the CLAUDE.md instruction "use `command gh` to bypass" creates a trap: you reflexively use it everywhere
+
+## Reproduction
+```python
+import subprocess
+# This fails: [Errno 13] Permission denied: 'command'
+subprocess.run(["command", "gh", "api", "/repos/..."], capture_output=True)
+
+# This works fine (RTK doesn't intercept Python subprocess):
+subprocess.run(["gh", "api", "/repos/..."], capture_output=True)
+```
+
+## Suggested fix
+Either:
+1. Document that `command gh` is only needed in Claude Bash tool, not Python subprocess
+2. Or make RTK not intercept `gh api` calls (only `gh --json` patterns that it compresses)
+
+## Impact
+Low — workaround is obvious once you know. But it cost ~2 minutes of confusion per occurrence.

Subject: [PATCH 37/38] fix: curl preserves JSON response values instead of
 schema-ifying

filter_curl_output now pretty-prints JSON with serde_json, keeping
actual data values intact. Previous behaviour replaced values with
type names (string, int) via json_cmd, destroying API response data.

Subject: [PATCH 38/38] fix: hook skips rewrite for subshell/backtick
 assignments

Commands containing =$( or =` are now skipped entirely by the rewrite
hook. The ENV_PREFIX regex misparsed VAR=$(grep ...) as an env prefix,
mangling the command. Safer to skip than to risk broken shell syntax.
