+# Setup Repo
+
+Bootstraps this clone in one pass:
+
+1. Activates repo git hooks
+2. Syncs generated skill mirrors for Claude, Codex, and Copilot
+
+Implementation layout:
+
+- Canonical entrypoint: `ai-artifacts/skills/shared/setup/setup-repo/scripts/Invoke-SetupRepo.ps1`
+- Repo convenience wrapper: `scripts/setup-repo.ps1`
+
+## Applicability (capability contract)
+
+This skill needs shell + filesystem access in a local git checkout. In chat-only environments,
+provide the exact commands and explain what each command configures.
+
+## Default command
+
+```powershell
+pwsh scripts/setup-repo.ps1
+```
+
+## Common variants
+
+Project-local mirrors for one harness:
+
+```powershell
+pwsh scripts/setup-repo.ps1 -Target Copilot -Scope Project
+```
+
+User-scope mirrors for all harnesses:
+
+```powershell
+pwsh scripts/setup-repo.ps1 -Scope User
+```
+
+Bootstrap only missing generated mirrors (keeps existing generated files untouched):
+
+```powershell
+pwsh scripts/setup-repo.ps1 -IfMissing
+```
+
+Refresh generated mirrors without touching git hooks:
+
+```powershell
+pwsh scripts/setup-repo.ps1 -SkipHooks
+```
+
+Check generated mirrors for drift:
+
+```powershell
+pwsh scripts/setup-repo.ps1 -SkipHooks -Check
+pwsh scripts/setup-repo.ps1 -SkipHooks -Target Codex -Skill tdd -Check
+```
+
+Run only one phase:
+
+```powershell
+pwsh scripts/setup-repo.ps1 -SkipHooks
+pwsh scripts/setup-repo.ps1 -SkipSkillSync
+```
+
+## Verify
+
+```powershell
+git config --get core.hooksPath
+Test-Path .claude/commands
+Test-Path .agents/skills
+Test-Path .github/skills
+pwsh scripts/setup-repo.ps1 -SkipHooks -Check
+```
+
+Expected:
+
+- `core.hooksPath` prints `.githooks`
+- mirror folders exist for selected targets
