code-review hunts bugs, ponytail-audit hunts bloat, medusa hunts secrets. Nothing asked the structural question: where does this codebase hold one truth in two places, mix two reasons to change in one unit, or trust an input it never validated. Those defects pass every test and every linter. Six lenses, each with a falsification test rather than a feeling: DRY demands the proven shared reason to change, so two blocks that merely look alike stay separate; SRP demands two nameable stakeholders; security stays at the trust boundaries and stays defensive. The silent-defaults lens routes to no-defaults instead of restating it. The rules exist to keep the report worth reading. A finding carries file:line the agent actually read, one hit is not a pattern, and a finding whose worst case is "feels wrong" is deleted rather than softened - the expensive ones go through dialectic first. A deliberate ponytail: marker is a known ceiling, not a finding. Read-only by construction, so auto-feature can run it as a first pass without side effects.

skills 🧠
The agent skill collection of Kevin Veen-Birkenbach.
Every skill is pinned in skills-lock.json for reproducible installs.
First-party skills live under skills/ and are layered on top of the locked ones at install time.
Compatible with Claude Code, Codex, Gemini CLI, Cursor, Copilot, Windsurf, Cline, and other agents.
Requirements 📦
- Node.js (provides
npx skills). jq(only required formake update).
Installation 🚀
Install the skills globally into your home (~/.agents/skills and ~/.claude/skills):
make install
Copy the skills into a specific project (<repo>/.agents/skills and <repo>/.claude/skills):
make project TARGET=/path/to/repo
Both commands also patch the target's .claude/settings.json: the caveman and ponytail plugins are enabled so their modes auto-activate on session start, and two reminder hooks are registered — autotune points you at /autotune at most once an hour, dream points you at /dream at most once every twelve hours per repository (stamped in that repository's git dir). Existing settings are preserved.
Restart your agent afterwards so it loads the new skills.
Maintenance 🔧
Refresh every skill to its latest version and rewrite skills-lock.json:
make update
Validate skills-lock.json and shellcheck the scripts (also run by CI on every push and after every update):
make test
