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

review-and-refactor 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.

Review and Refactor

Act as a senior software engineer. Review the specified code (or the full project) and apply refactoring improvements while maintaining correctness.

Instructions

Step 1: Understand the Standards

Check for project-level coding guidelines in common locations:

  • CONTRIBUTING.md, CODING_STANDARDS.md, or similar docs
  • Linter/formatter configs (.eslintrc, pyproject.toml, .editorconfig)
  • Existing code patterns and conventions

If coding standards exist, all refactoring must conform to them.

Step 2: Review the Code

Analyze each file for these issues:

Readability

  • Unclear variable or function names
  • Missing or misleading comments
  • Overly complex expressions that could be simplified
  • Inconsistent formatting or style

Maintainability

  • Functions longer than ~40 lines (candidates for extraction)
  • Duplicated logic across files
  • Deep nesting (> 3 levels) that could be flattened
  • Magic numbers or hardcoded strings (extract to constants)

Best Practices

  • Missing error handling or overly broad exception catches
  • Unused imports, variables, or dead code
  • Mutable default arguments or other language-specific pitfalls
  • Missing type hints or annotations (where the project uses them)

Step 3: Refactor

Apply improvements while following these rules:

  1. Keep existing file structure — do not split files unless explicitly asked.
  2. Preserve behavior — refactoring must not change what the code does.
  3. Run tests after changes — if the project has tests, verify they still pass.
  4. Make small, reviewable changes — each refactoring should be easy to understand.

Step 4: Summarize

After refactoring, provide a summary:

## Refactoring Summary

### Changes Made
| File | Change | Reason |
|------|--------|--------|
| ... | ... | ... |

### Tests
- All existing tests: PASS / FAIL
- New issues introduced: None / <list>

### Recommendations
- <any further improvements that were out of scope>

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.
