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-review 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 2mo 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.

Code Review

Perform thorough code review analyzing quality, potential bugs, security issues, and suggesting improvements.

Parameters

{
  "type": "object",
  "properties": {
    "target": {
      "type": "string",
      "description": "File path, directory, or glob pattern to review"
    },
    "focus": {
      "type": "string",
      "enum": ["general", "security", "performance", "maintainability"],
      "description": "Primary focus area",
      "default": "general"
    }
  },
  "required": ["target"]
}

When to Use

  • User asks to "review" or "check" code
  • User wants to find bugs or issues
  • User asks about code quality
  • User wants security analysis
  • User asks for improvement suggestions

Methodology

Phase 1: Context Gathering

  • Read the target files
  • Understand the codebase structure
  • Identify the programming language and framework
  • Check for related tests and documentation

Phase 2: Analysis

  1. Logic Review: Check for bugs and edge cases
  2. Security Scan: Look for vulnerabilities (injection, auth issues, etc.)
  3. Performance Check: Identify bottlenecks and inefficiencies
  4. Style Review: Check consistency and best practices

Phase 3: Prioritization

  • Categorize issues by severity (Critical, High, Medium, Low)
  • Focus on actionable feedback
  • Provide concrete examples

Phase 4: Output

Provide structured review with:

  • Summary of findings
  • Issues list with severity and line numbers
  • Specific improvement suggestions
  • Code examples where helpful

Guidelines

  • Be constructive, not just critical
  • Provide specific line references
  • Explain WHY something is an issue
  • Suggest concrete fixes, not just problems
  • Acknowledge good patterns when found
  • Consider the project's existing style

Examples

Example 1: File Review

User Input: "Review src/auth.ts for security issues"

Expected Behavior:

  1. Read the file and understand authentication flow
  2. Check for common security issues (SQL injection, XSS, weak crypto)
  3. Verify input validation and sanitization
  4. Check for proper error handling
  5. Provide prioritized list of findings with fixes

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.
