feat: add_component — lift a starter's CI/CD layer into an existing repo#56
Merged
Conversation
The remediation half of the audit loop: audit_* diagnose gaps against the Starter Series bar; add_component installs the missing files from the matching starter. MCP tool + CLI subcommand + /add-component slash command. - Component groups: ci / security (codeql + SECURITY.md) / dependabot (+auto-merge) / maintenance (stale + weekly health) / all. Deliberately never lifts cd*.yml (secrets — deploy-setup's job), setup.yml, update-changelog.yml, PR templates, or app code. - Safety: dry-run by default (per-file plan: create / identical / skip-exists / overwrite); refuses a dirty git tree unless force; existing-but-different files skipped unless force — the dry-run plan doubles as a drift report against the starter (v1 answer to update_component). - Reuses scaffold machinery: fetchTarball caps (50MB/30s/3 retries), safe extract, extractStarterSignals auto-detection (warns below high confidence). - 10 new tests (123/123 green); verified e2e against the real browser-extension-starter: auto-detected, downloaded the live tarball, all 7 files identical.
