What it does

Code Quality Review is an agent skill from bitsocialnet/5chan. Review a task-owned diff for correctness, regression risk, and unnecessary complexity when a quality review is requested or called for by repository policy.

Its SKILL.md is about 630 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Code quality. The repository describes itself as: A peer-to-peer 4chan alternative. The licence is GPL-3.0.

When your agent uses it

  • Tasks that involve Code quality

Example prompts

  • “/code-quality-review”

What it can do on your machine

Read from SKILL.md and the folder at commit a31f565. 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

    Shell commands in SKILL.md call:

    • yarn

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

  • Network

    No URLs in SKILL.md. Its commands use yarn, which can reach the network depending on how they are called.

    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

Code Quality Review loads about 633 tokens when it runs. Until then it costs about 44 tokens; SKILL.md has 316 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~44
When it runs · the whole SKILL.md, loaded when a task matches
~633

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.

Code Quality Review

Review against the user's base, or the task's base branch plus its relevant staged, unstaged, and untracked changes. Preserve unrelated work. Read nearby source, changed tests, and applicable repository guidance before judging a hunk.

Focus on evidence-backed bugs, error paths, races, state consistency, trust boundaries, and concrete verification gaps. Challenge each finding against the implementation and intended behavior. Apply architecture and performance guidance only where the changed flow makes it relevant; when files or imports moved, run yarn boundaries instead of judging the module boundaries in src/AGENTS.md by eye.

For simplification, use the repository's solution ladder: remove unnecessary work, reuse existing code or platform facilities, and only then introduce new code. Do not trade away correctness, accessibility, validation, error handling, or useful tests. Preserve an unfamiliar guard or workaround until its purpose is understood.

Return actionable findings with file/line evidence, impact, how to show the failure (an input, test, or command) for a bug, and a practical correction, prioritized by risk. Skip tooling-handled style nits and speculative cleanup; if none remain, say so without a canned approval or publishing instruction.

A review-only request returns findings without edits. During an authorized implementation, apply high-confidence in-scope fixes without asking again for that authorization. This is an advisory pass, not an extra approval gate. Reuse verification evidence for the same final state; consult docs/agent-playbooks/verification.md only when a change or concrete uncertainty calls for more checks.

When a substantive review correction exposes a preventable mistake, use retro to identify useful prevention. Keep review-only requests read-only and reuse existing coverage where sufficient.

For an explicitly scoped semantic second opinion, use Jev diff review via the repository root. Select only relevant changed files and rules; the helper is opt-in, sends selected content only with --live, and returns advisory issues or uncertainty. Keep deterministic lint/tests and independent review authoritative. Do not wire it into automatic edit, commit, or repair hooks.
