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 | $0.00061 | $0.02213 |
| Opus 5.5 | $0.00024 | $0.00885 |
| Sonnet 5.5 | $0.00012 | $0.00443 |
| Haiku 4.5 | $0.00006 | $0.00221 |
Grade A, and why
code-quality 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 — 322 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Code Quality
Production-grade code standards and review for TypeScript, Python, Go, and Rust.
When to Use
- Writing or reviewing code in TS/Python/Go/Rust
- Code review or pull request analysis
- Security or performance audit
- Setting up linting/CI for a project
- Python-specific style check (PEP 8)
Quick-Start Modes
| Intent | Sections to Use |
|---|---|
| Write code | Core Rules + Language Standards + AI-Friendly Patterns |
| Review PR | Review Process + references/checklist.md + Severity Levels |
| Setup CI | Config Files + Scripts + Enforcement Strategy |
| Python style | references/python.md (full PEP 8 deep-dive) |
Context loading: For deep reviews, read the relevant references/ file for the language under review.
Quick Reference
| Language | Type Safety | Linter | Complexity |
|---|---|---|---|
| TypeScript | strict, no any |
ESLint + typescript-eslint | max 10 |
| Python | mypy strict, PEP 484 |
Ruff + mypy | max 10 |
| Go | staticcheck | golangci-lint | max 10 |
| Rust | clippy pedantic | clippy + cargo-audit | - |
Severity Levels
| Level | Description | Action |
|---|---|---|
| Critical | Security vulnerabilities, data loss | Block merge |
| Error | Bugs, type violations, any |
Block merge |
| Warning | Code smells, complexity | Must address |
| Style | Formatting, naming | Auto-fix |
Core Rules (All Languages)
Type Safety
- No implicit any / untyped functions
- No type assertions without guards
- Explicit return types on public APIs
Security
- No hardcoded secrets (use gitleaks)
- No eval/pickle/unsafe deserialization
- Parameterized queries only
- SCA scanning (npm audit / pip-audit / govulncheck / cargo-audit)
Complexity
- Max cyclomatic complexity: 10
- Max function lines: 50
- Max nesting depth: 3
- Max parameters: 5
Error Handling
- No ignored errors (Go: no
_for err) - No bare except (Python)
- No unwrap in prod (Rust)
- Wrap errors with context

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.
- 1mo ago First seen · 322 lines · 61 tokens per session scan A c1a760c82ba1
code-quality is a skill published in the GitHub repository georgekhananaev/claude-skills-vault (30 stars, last pushed 2mo ago), licensed MIT. It adds 61 tokens to every session and 2,213 once invoked, about $0.0002 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.

r-tidyverse-style
Use when the user asks to review or clean up R code for tidyverse style, standardize formatting or names, remove redundant comments or wrappers, or make a behavior-preserving style pass. Also use when writing substantial new R package code if the user requests tidyverse style or the package already follows it. Not for…
