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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00072 | $0.00909 |
| Opus 5 | $0.00036 | $0.00454 |
| Sonnet 5 | $0.00014 | $0.00182 |
| Haiku 4.5 | $0.00007 | $0.00091 |
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 3d 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 Skill
Purpose
Code review focused on quality, structure, naming, and maintainability. For security reviews, use /security-verify scan.
Quick Start
/code-review <file-path>
Review Categories
1. Code Quality (Critical)
File Organization
- File size <= 500 lines
- Single responsibility
- Clear module structure
Naming
- Self-documenting names
- Verbs for functions, nouns for data
- Consistent naming style (snake_case/camelCase)
- No abbreviations
Type Hints (Python) / Types (TS)
- All function parameters typed
- Return types specified
- No implicit
Any
Docstrings/Comments
- Google-style docstrings on public API
- Comments explain WHY, not WHAT
- No commented-out code
2. Error Handling
- Specific exception types
- No bare
except: - Clear error messages
- Cleanup in finally/with blocks
3. Complexity
- Functions < 50 lines
- Cyclomatic complexity < 10
- Nesting depth < 4 levels
- No deep callback chains
4. Testing Readiness
- Dependencies injectable
- Side effects isolated
- Pure functions where possible
5. Style
- Consistent formatting
- Imports organized
- No unused imports/variables
Review Output
# Code Review: src/module.py
## Quality Score: 8/10
## Critical Issues (Must Fix)
- Line 45: Function `process_data` is 78 lines. Split into smaller functions.
## Important Issues (Should Fix)
- Line 23: Missing type hint on return value
- Line 67: Bare `except:` - specify exception type
## Suggestions
- Line 12: Consider extracting magic number 86400 to constant
## Strengths
- Clear function naming
- Good separation of concerns
Common Issues Checklist
Python
- No mutable default arguments
- Using context managers for resources
- No string concatenation in loops
- Using generators for large datasets
TypeScript
- Strict mode enabled
- No
anytypes - Proper null checks
- No type assertions without reason
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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-review is a skill published in the GitHub repository matteocervelli/llms (25 stars, last pushed 3mo ago), licensed MIT. It adds 72 tokens to every session and 909 once invoked, about $0.0004 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 2026-09-03.
