README
mizchi/skills
A collection of agent skills maintained by @mizchi, distributed via APM (Agent Package Manager).
Each directory is a standalone skill following the agentskills.io open standard.
Install
Install an individual skill (global / user scope):
apm install -g mizchi/skills//
Or add to a project’s apm.yml:
dependencies:
apm:
- mizchi/skills//
Pin to a tag:
apm install -g mizchi/skills//#v0.1.0
These follow the open Agent Skills format, so any
compatible agent (Claude Code, Codex, opencode, Gemini CLI, Cursor, …) can use
them without APM. Each skill’s README shows a npx skills add command (the
skills CLI, installs into every
detected agent) and a raw npx degit folder copy as alternatives:
npx skills add mizchi/skills --skill
Every skill directory carries its own README.md with copy-paste install
examples, generated from the skill’s SKILL.md frontmatter. Regenerate them all
after editing any frontmatter:
pkf run gen:readme # write / sync every skill README
pkf run check:readme # CI: verify they are in sync

Tools
waxa — skill evaluation CLI
Lives at tools/waxa/ and is published as @mizchi/waxa. Used by the waxa-eval skill, and forms the adoption gate of skill-finder.
Run via npx (no global install needed):
npx @mizchi/waxa
npx caches the package after the first run, so subsequent invocations are fast. Pin a version with npx @mizchi/[email protected] when reproducibility matters (do not pin 0.1.0 — that release shipped a broken shebang and crashes before argv parsing).
Alternatives:
# install globally (when calling waxa frequently)
npm i -g @mizchi/waxa
# run from source (requires Deno 2+)
git clone https://github.com/mizchi/skills.git
cd skills/tools/waxa
deno task run -- path/to/eval.yaml
Requirements: claude CLI on PATH and authenticated (OAuth login or ANTHROPIC_API_KEY).
Quick reference:
npx @mizchi/waxa init [--skill ] [--force] # scaffold /evals/ (skill-local)
npx @mizchi/waxa /evals/eval.yaml # single run
npx @mizchi/waxa /evals/eval.yaml --baseline # with_skill vs without_skill + delta
npx @mizchi/waxa iterate /evals/eval.yaml [--max N] # iteration loop with ledger
npx @mizchi/waxa compare /evals/eval.yaml --models , # multi-model comparison
npx @mizchi/waxa variant /evals/eval.yaml --base --candidate # A/B
From 0.2.0 evals live at /evals/ (skill-local layout, agentskills.io-aligned). Workspace outputs go to /results//iteration-N/. The npm package bundles references/empirical-prompt-tuning.md (the methodology document), so iter / convergence semantics ship with the CLI.
Full reference: tools/waxa/README.md.
Recommended starter set
If you are setting up a new project that will produce or consume skills, this combination covers selection, discovery, and iteration:
# apm.yml
targets:
- claude
dependencies:
apm:
- mizchi/skills/tooling/apm-usage # APM manifest reference
- mizchi/skills/meta/skill-selector # Phase 1: pick from curated catalog
- mizchi/skills/meta/skill-finder # Phase 2: cross-source discovery + waxa eval gate
- mizchi/skills/meta/waxa-eval # waxa CLI operating manual
- mizchi/skills/meta/empirical-prompt-tuning # methodology / Iter 0 / [critical]-tag checklist
Then:
apm install # installs the skills under .claude/skills/
npx @mizchi/waxa --help # cache the waxa CLI on first call
# (or `npm i -g @mizchi/waxa` if you call waxa often enough that startup matters)
The skill-selection / discovery / evaluation flow then proceeds as: skill-selector (catalog pre-flight) → if no fit, skill-finder (Tier 1-4 sweep) → adoption gated by waxa-eval running waxa iterate against a evals// directory you author. empirical-prompt-tuning covers what waxa cannot reach (the Iter 0 description / body consistency check, tool_uses-based skill self-containment diagnosis, and the [critical]-tagged requirements checklist that gives binary success judgment).
Language
All SKILL.md files are written in English. Skills that were originally written in Japanese preserve the original as SKILL-ja.md alongside the English version. mizchi-blog-style is the single exception and stays Japanese-only because the skill itself is about Japanese blog writing style.
Upstream skills (not in this repo)
These are maintained in their own repositories and installed separately:
