A portable tuner: nothing that reduces logic, coverage or correctness counts as a speed-up. Once per session it asks through active-listening, as checklists, what to examine, which performance boundaries hold and which limits apply to optimizations, and works only inside the answers. It measures from logs (profile_tasks durations sit under the next task's header, BuildKit steps pair by number), ranks candidates by fixed cost times count, discards invalid comparisons (shared machine, differing cache state checked by instruction text and base digest, one-time costs, fresh versus update passes), and searches every branch before optimizing. A change of language, such as a Python hot path in Rust, is considered only for measured CPU-bound work, counted at its full toolchain and shipping cost, and applied only where the session's limits allow new languages. Every optimization runs through the funnel skill and is hardened with dialectic. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
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.local.json — the machine-local, untracked file, so a project's reviewed .claude/settings.json is never rewritten by an install: 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
