In the author's own words, from each skill's SKILL.md — showing the first 30 of 73 files.

• actions-ci-tuning

  Use when auditing or improving GitHub Actions workflows for a project. Covers cache setup (npm/pnpm/yarn), job parallelism, shard-based test splitting, artifact handling pitfalls, and Playwright-specific patterns. Trigger on: slow CI, cache miss, flaky shard jobs, merge-reports failures, or an explicit 'tune CI' request.

• ai-index

  Method and tooling for measuring how AI-generated a piece of prose reads, in Japanese or English. Two layers — a deterministic lint for removable surface tells (scripts/slopscore.py, no API) and a judgment layer of typed probabilistic questions (Jev noul/score) for the tells that survive editing. Includes measured human/AI baselines, a gap-first calibration procedure, and labeled fixtures. Use wh…

• apm-usage

  Reference for APM (Agent Package Manager) — apm.yml syntax, install / uninstall / update commands, target detection, lockfile workflow. Read when you need exact field names, but do NOT auto-invoke on every apm-related task; user prompts about projects with installed skills can be handled with general APM knowledge. Invoke explicitly when the user mentions APM by name, asks to author or audit an a…

• ast-grep-practice

  Operate ast-grep as a project lint tool. Covers sgconfig.yml, fix/rewrite rules, constraints, transform, testing, and CI. Use when writing rules ast-grep can express but general-purpose linters cannot.

• dotenvx

  Use when working with the `dotenvx` env-var management tool — encrypting .env files, juggling multiple environments (.env.production / .env.staging / .env.ci), committing encrypted secrets to git with `.env.vault` / `.env.keys` / `.env.encrypted`, or wiring dotenvx into GitHub Actions. Trigger on `.env.vault` / `.env.keys` / `dotenvx` commands or symptoms (env-var leak risk, env per-stage managem…

  frontend-review-deps/SKILL.md on GitHub (opens in a new tab)

• frontend-review-hygiene

  Use when assessing code quality hygiene — TypeScript strictness, lint violations, dead code, and duplication. Runs `audit-typescript.sh`, `audit-lint.sh`, `audit-similarity.sh`. Does NOT cover dependency freshness or CVE audit — use `frontend-review-deps` for that.
