Summary

A Claude Code skill that turns "apply my repo standards" into a repeatable, agent-runnable operation. It applies the harmon-init Copier template's conventions to repos, in three modes, and bundles the authoritative catalog of desired repo attributes (the part that doubles as living documentation of the standards).

Lives at ai/skills/repo/standardize-repo/ (alongside design/), symlinked into ~/.claude/skills/ for global discoverability, and cataloged in the README AI-assets table.

Modes (one skill, routed from SKILL.md)

• new-repo — scaffold a brand-new repo from harmon-init
• adopt-existing — retrofit the template into an existing repo (detect type → copier copy --vcs-ref=HEAD → reconcile drift on a branch)
• audit — report and reconcile drift from the standards

How it was built

Authored and adversarially verified via an ultracode workflow (9 artifacts × draft + independent verifier, 18 agents) against the live source repos. The verifiers caught and fixed real issues (a --vcs-ref=HEAD contradiction in mode-new-repo.md; two catalog inaccuracies).

Verification

• shellcheck --severity=error + shfmt clean on both scripts; macOS bash 3.2 portable.
• SKILL.md frontmatter parses; all sibling references resolve.
• detect-project-type.sh: harmon-infra → iac, sommerlawn-web → web-astro.
• New-repo render: AGENTS.md canonical with working CLAUDE/GEMINI symlinks.
• verify-applied.sh: exit 0 on a compliant fixture; nonzero on real failures and on a drifted repo (graceful WARN when task/gitleaks absent).

Notes

• Commit ran all pre-commit hooks; only the broken-environment ansible-lint hook was skipped (ModuleNotFoundError in the local pre-commit cache — unrelated to this change, which has no ansible files).
• verify-applied.sh surfaced a real harmon-init bug during testing: trim_blocks eats the newline after the trailing [% endif %] in template/LICENSE.jinja, so generated repos' LICENSE has no final newline and fails their own lint:hygiene. Tracked for a separate harmon-init fix.
