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-reviewer-react 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 1mo 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.

How it starts

The opening of the file, as written. The whole thing — 195 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Positioning

Focused on logic and structure review of React + TypeScript frontend code. Checks whether code is correct, robust, and maintainable.

Difference from code-audit: code-audit focuses on CSS/styling/visual aspects (spacing, colors, responsiveness); this skill focuses on JS/TS logic (component design, types, Hooks, performance, error handling).

Execution timing: After code submission, before merge; or when user explicitly requests review Scan scope: Specified files, or file list obtained via git diff


Review Process

Step 1: Determine Review Scope

Determine files to review by priority:

  1. Files or directories explicitly specified by user
  2. User mentions PR or branch → run git diff --name-only <base>..HEAD to get changed files
  3. User says "look at recent changes" → run git diff --name-only HEAD~1 to get last commit changes
  4. None of the above → ask user which files to review

Only review .ts / .tsx / .js / .jsx files. Skip test files (*.test.* / *.spec.*), type declaration files (*.d.ts), and config files.

Step 2: Per-file Review

Read the complete file content first, understand context, then check each item. Don't just look at the diff — local changes may introduce problems in the global context. Execute the following review items for each file.

Step 3: Summary Report

Generate a structured report using the output template at the bottom.


Review Checklist

1. Component Design

Good components are highly cohesive and loosely coupled. Check whether components have single responsibility and clear interfaces.

Check items:

  • Single component exceeds 300 lines → suggest splitting into sub-components
  • More than 8 Props → may need consolidation into an object or component splitting
  • Components defined inside other components (nested definitions) → recreated every render, causing state loss
  • Prop drilling (props passed through 2+ layers) → consider Context or composition patterns
  • Component handles both data fetching and UI rendering → suggest separating into container + presentational
  • Unused props or imports

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.
