Pressing ArrowUp in an empty composer recalls messages previously sent in the open chat (newest first), like a shell; ArrowDown walks forward again and finally restores whatever draft was in the box. Handy when you want to resend or tweak something you asked earlier without hunting through the transcript.

History is kept per chat, keyed by the same session-or-project: scope drafts use, so recall never surfaces text from another conversation; the first message of a brand-new chat is recorded under its freshly allocated session id so it is recallable where the user lands. Storage is browser-local (localStorage, capped at 100 entries per scope and 100 scopes with oldest-first eviction) and records regular sends, queued messages, and slash commands.

The arrows keep their normal meaning everywhere else: the handler only takes over when the box is empty or still showing an untouched recall, and it runs after the command-menu and file-mention handlers so their navigation is unaffected. Editing a recalled message hands the arrows back to the caret. No visual changes.

Tested with a new vitest suite for the hook (useInputHistory.test.ts, incl. scope isolation and eviction); npm run test:client, npm run typecheck, and npm run build all pass.

Summary by CodeRabbit

  • New Features

    • Added shell-style input history to the chat composer.
    • Recall previous messages with Arrow Up and navigate forward with Arrow Down.
    • Preserves drafts while browsing history and keeps history separate across chats.
    • Avoids storing blank or consecutive duplicate messages.
    • Records sent messages and commands for later recall.
  • Bug Fixes

    • Improved keyboard handling so editing and modified arrow-key actions behave normally.
    • Keeps recalled entries stable while navigating, even when history changes elsewhere.

📝 Walkthrough

Walkthrough

The chat composer now records scoped input history and supports ArrowUp and ArrowDown navigation. Recall updates React state and the input ref. Active recall uses a stable history snapshot. Tests cover navigation, scopes, drafts, filtering, limits, eviction, modifiers, malformed storage, and storage changes.

Changes

Chat input history

Layer / File(s) Summary
Stable history navigation
src/modules/chat/hooks/useInputHistory.ts
Recall navigation keeps the history snapshot captured at recall start. ArrowUp and ArrowDown use that snapshot and restore the original draft when navigation ends.
Composer wiring and message recording
src/modules/chat/hooks/useChatComposerState.ts
Connects history navigation to keyboard handling, synchronizes recalled input with composer state and the input ref, and records queued messages, slash commands, and normal sends under the relevant session scope.
History behavior tests
src/modules/chat/tests/useInputHistory.test.ts
Tests recording, navigation, draft restoration, scopes, editing rules, modifier keys, limits, eviction, malformed storage, and stable recall snapshots.

Poem

A rabbit records each message bright
Scoped safely through the quiet night
ArrowUp finds thoughts in a row
ArrowDown restores the draft below
New storage changes do not shift the flight
The composer keeps its history right

Merge Risk: 🟡 Moderate · up to 5c9d8

The feature can save failed or cancelled slash commands for later recall, and two brand-new chats in the same project can share recalled command text before session assignment. These are bounded but concrete correctness and privacy issues, so merge should wait for a fix or explicit owner acceptance.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Record the slash command only after it succeeds.

executeCommand(...) starts asynchronously, but this line records currentInput immediately. A failed command response or a declined Bash confirmation still creates a history entry for a command that did not execute.

Return an execution result from executeCommand, or record within its successful branch.

ArrowUp in an empty composer recalls messages previously sent in the
open chat, newest first; ArrowDown walks forward and finally restores
the draft. History is kept per chat scope (the same session-or-project
key drafts use) in localStorage, capped per scope and across scopes,
and recorded on send, queue, and slash-command execution. The arrows
keep their normal meaning while editing text or navigating the
command/mention menus.

An append from another tab mid-recall shifted what ArrowDown landed on
and could displace the draft restore. Navigation now snapshots the
entries when recall starts and walks that array until recall ends.

Switching sessions while a queued message's attachments uploaded hit
the early return after persistence, so the message dispatched later
without ever entering input history. Record it right after persistence,
under the session it was queued for.

ArrowUp in an empty composer walks back through messages already sent in this
project, ArrowDown walks forward and finally restores the draft recall
interrupted. Editing a recalled message hands the arrows back, and a walk keeps
the snapshot it started with so a send from another tab cannot shift it.

Scoped by project rather than upstream's per-session, matching how drafts are
already keyed here: a fresh chat still recalls what was typed in its siblings.
Browser-local, so no adapter is involved.

Reimplemented from upstream siteboon#1238; the arrow-walk is a pure function here so it
is covered without rendering a composer.
