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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00033 | $0.00302 |
| Opus 5.5 | $0.00013 | $0.00121 |
| Sonnet 5.5 | $0.00007 | $0.00060 |
| Haiku 4.5 | $0.00003 | $0.00030 |
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 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.
What it actually says
Code Review
When reviewing code, follow this process:
Step 1: Understand the Change
Run git diff (or git diff --staged for staged changes) to see what changed.
Read the modified files in full to understand the surrounding context.
Step 2: Check for Issues
Review each changed file for:
Correctness
- Logic errors, off-by-one errors, race conditions
- Missing null/undefined checks at system boundaries
- Incorrect error handling (swallowed errors, wrong error types)
Security
- SQL injection, XSS, command injection
- Hardcoded secrets or credentials
- Overly permissive file/network access
Performance
- N+1 queries, unnecessary loops, large allocations
- Missing indexes for new database queries
- Blocking operations in async code
Maintainability
- Unclear naming, overly complex logic
- Dead code, unused imports
- Missing types in TypeScript
Step 3: Report
Format your review as:
- Summary: One sentence on what the change does
- Issues: Specific problems with file paths and line numbers
- Suggestions: Optional improvements (clearly marked as optional)
Be direct. Don't pad with praise. Focus on things that matter.
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 owainlewis/youtube-tutorials (408 stars, last pushed 23d ago), licensed MIT. It adds 33 tokens to every session and 302 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-08-30.
