Add hosts/copilot-cli.ts with tool rewrites mapping Claude Code tools to Copilot CLI equivalents (view, create, edit, bash, grep, glob, task, ask_user, web_fetch). Path rewrites translate .claude/skills → .copilot-cli/skills and CLAUDE.md → AGENTS.md. Suppressed resolvers: CODEX_SECOND_OPINION, CODEX_PLAN_REVIEW (Codex-specific), GBRAIN_CONTEXT_LOAD, GBRAIN_SAVE_RESULTS (not available). REVIEW_ARMY, ADVERSARIAL_STEP, and DESIGN_OUTSIDE_VOICES are kept — they map to Copilot CLI's task tool for parallel sub-agent dispatch. Includes boundary instruction to prevent reading .claude/ skill definitions. - Generation: bun run gen:skill-docs --host copilot-cli (36 skills) - Detection: cliCommand 'gh' with alias 'copilot' - Install path: ~/.copilot-cli/skills/gstack - All 355 gen-skill-docs tests pass - All 73 host-config tests pass (count bumped 10→11) Co-authored-by: Copilot <[email protected]>
Copilot CLI discovers personal skills at ~/.copilot/skills/ and project skills at .github/skills/ (not .copilot-cli/). Updated: - globalRoot: .copilot-cli → .copilot (matches ~/.copilot/ config home) - localSkillRoot: .copilot-cli → .github (native project skill path) - hostSubdir: .copilot-cli → .copilot (build output dir) - cliCommand: copilot is the actual binary (gh is an alias) - All path rewrites and boundary instruction updated Skills are now auto-discovered by /skills list without manual /skills add.

Summary
Adds GitHub Copilot CLI as gstack's 11th supported host.
What's included
hosts/copilot-cli.ts— Declarative host config following the pattern inADDING_A_HOST.mdhosts/index.ts— Registration in the host registry.gitignore— Added.copilot-cli/for generated skill docstest/host-config.test.ts— Bumped host count assertion (10→11)Design decisions
Tool rewrites — Copilot CLI uses different tool names than Claude Code:
Path rewrites:
.claude/skills/gstack→.copilot-cli/skills/gstackCLAUDE.md→AGENTS.md(Copilot CLI reads AGENTS.md as custom instructions)Suppressed resolvers:
CODEX_SECOND_OPINION,CODEX_PLAN_REVIEW— Codex-specificGBRAIN_CONTEXT_LOAD,GBRAIN_SAVE_RESULTS— Not availableKept resolvers:
REVIEW_ARMY,ADVERSARIAL_STEP,DESIGN_OUTSIDE_VOICES— these map to Copilot CLI'stasktool which supports parallel sub-agent dispatch (similar to Claude's Agent tool)Detection:
cliCommand: 'gh'with alias'copilot'. The GitHub CLI (gh) hosts the Copilot CLI extension.Boundary instruction: Prevents the agent from reading
.claude/or.agents/directories.Verification
Context
I use GitHub Copilot CLI as my primary AI coding agent. gstack's methodology (especially /review, /office-hours, /cso) is exactly what's missing from my workflow. The generated skill docs work as reference documents that the agent reads on demand via its
viewtool.TODO (follow-up PRs)
copilot-clidetection to setup script (gh copilot --versioncheck)
