What it does

Frontend Review Hygiene is an agent skill from mizchi/skills. 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.

Its SKILL.md is about 720 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `README.md`).

It sits in Development, covering Linting and formatting, Vulnerability scanning and Code quality. It works with TypeScript. The repository describes itself as: Agent skills by mizchi, distributed via APM.

When your agent uses it

  • Assessing code quality hygiene — TypeScript strictness
  • Lint violations

Example prompts

  • “/frontend-review-hygiene”

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. In parallel, run
  2. Read each raw/*.json.
  3. Compare with the previous run if /.frontend-review/kpi/baseline.json exists.

What it can do on your machine

Read from SKILL.md and the folder at commit 62f5808. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Frontend Review Hygiene loads about 717 tokens when it runs. Until then it costs about 72 tokens; SKILL.md has 291 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~72
When it runs · the whole SKILL.md, loaded when a task matches
~717

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 291 words (~717 tokens).

“You are assessing the baseline code quality hygiene of a frontend project: types, lint, dead code, and duplication. These are the KPIs that will be ratcheted each week.”
