code-quality

A code-quality review process for TypeScript and React files that combines automated checks with a manual review of common code and accessibility problems.

In plain words
What is it for?
Use it to check files or folders for unsafe types, weak error and loading states, missing empty states, accessibility gaps, styling issues, oversized functions, and import problems.
Why use it?
It brings linting, type checking, formatting, and practical review criteria together so issues are easier to find before code is merged.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Made for: Claude Code.

Per session 10 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 429 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

code-quality scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Code Quality Review

Review code quality in: $ARGUMENTS

Instructions

1. Identify target files

Find all .ts and .tsx files in the target path. Exclude node_modules, dist, .next, and generated files (*.generated.*, *.d.ts).

2. Run automated checks

# Lint
npx eslint --no-error-on-unmatched-pattern $ARGUMENTS

# Type check
npx tsc --noEmit

# Format check (don't fix, just report)
npx prettier --check $ARGUMENTS

3. Manual review checklist

For each file, verify:

  • No TypeScript any types (use unknown with type guards)
  • No type assertions without // SAFETY: comment
  • Error handling: all catch blocks surface feedback to user
  • Loading states: isPending && !data pattern, not bare loading
  • Empty states: every list has an explicit empty state
  • Mutations: triggers disabled during pending, onError shows toast
  • Accessibility: semantic HTML, alt text, keyboard support
  • No inline styles for layout — use Tailwind/CSS modules
  • Functions under 50 lines, components under 250 lines
  • Imports: no circular dependencies, no deep barrel re-exports

4. Report findings

Organize by severity:

CRITICAL (must fix before merge)

  • Security vulnerabilities, data loss risks, logic errors

WARNING (should fix)

  • Convention violations, accessibility gaps, missing error handling

SUGGESTION (consider improving)

  • Naming, readability, minor performance gains

Include file:line references and example fixes for each finding.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

code-quality is a command published in the GitHub repository Piyush8296/claude-workspace (2 stars, last pushed 4mo ago), licensed MIT. It adds 10 tokens to every session and 429 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
