Serve one plugin source (plugins/winapp/) to both GitHub Copilot and Claude Code via per-host manifests and marketplaces, eliminating the generated .claude/ mirror and its sync script. - Move the agent + 8 skills from .github/plugin/ into plugins/winapp/ (skill dirs renamed to winapp-<name> so both hosts load them with no transform step) - Add per-host plugin manifests: plugins/winapp/plugin.json (Copilot) and plugins/winapp/.claude-plugin/plugin.json (Claude) - Add per-host marketplaces: .github/plugin/marketplace.json (Copilot) and .claude-plugin/marketplace.json (Claude), both sourcing ./plugins/winapp - Keep the repo-root plugin.json as a thin shim so "copilot plugin install microsoft/WinAppCli" and the awesome-copilot listing keep resolving the repo as a plugin with no external change - Delete the .claude/ mirror and scripts/sync-claude-plugin.ps1 - Update generate-llm-docs.ps1 to write skills to plugins/winapp/skills/ and sync the version field across all 5 manifests; update validate-llm-docs.ps1 paths - Update .gitattributes and docs (README, llms.txt, AGENTS.md, internal pr-review dev skills) Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com>

Why
We currently maintain two skill trees: the hand-authored GitHub Copilot plugin under
.github/plugin/and a generated byte-identical Claude Code mirror under.claude/(produced byscripts/sync-claude-plugin.ps1). That's duplicate content to keep in sync for no real benefit.This PR follows the model already proven in the sibling repo
microsoft/win-dev-skills: serve one plugin source to both hosts via per-host manifests and marketplaces. No more mirror, no more sync script.What changed
Single plugin source — everything lives under
plugins/winapp/:.github/plugin/→plugins/winapp/(puregit mv, zero content change).winapp-<name>so both Copilot and Claude load them with no transform step (Claude requires dir == frontmattername; Copilot tolerates it).Per-host manifests (convention-based, like win-dev-skills):
plugins/winapp/plugin.json— Copilot manifest (agents/,skills: ["skills/"])plugins/winapp/.claude-plugin/plugin.json— Claude manifest (no agents/skills fields; addshomepage/repository)Per-host marketplaces, both sourcing
./plugins/winapp:.github/plugin/marketplace.json(Copilot).claude-plugin/marketplace.json(Claude)Root
plugin.jsonshim kept (load-bearing) — repointed atplugins/winapp/. This keepscopilot plugin install microsoft/WinAppCliand the awesome-copilot listing (plugins/external.jsonresolves the repo root as a plugin) working with no external coordination and no breakage window.Removed duplication:
.claude/mirrorscripts/sync-claude-plugin.ps1Tooling & docs:
generate-llm-docs.ps1now writes skills toplugins/winapp/skills/winapp-<name>/and syncs theversionfield across all 5 manifests (surgical regex replace, preserves hand-authored formatting; guarded so validator temp-dir runs don't mutate committed files).validate-llm-docs.ps1paths updated..gitattributes,README.md,llms.txt,AGENTS.md, and internal pr-review dev-skill docs updated.Install (after merge)
GitHub Copilot CLI — unchanged:
Claude Code — new:
The agent frontmatter keeps its existing
infer: true(automatic activation). win-dev-skills instead usesuser-invocable: true(explicit-only). I preserved current behavior to avoid a regression; Claude tolerates the unknowninfer:key. If we'd rather match win-dev-skills' explicit-invocation model, say so and I'll switch it.Verification
generate-llm-docs.ps1: 8 skills regenerate intoplugins/winapp/skills/, manifest versions sync to0.4.1.validate-llm-docs.ps1 -FailOnDrift→ passes (schema + all skills up-to-date, exit 0).Co-authored-by: Copilot App 223556219+Copilot@users.noreply.github.com
