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 | $0.00028 | $0.00420 |
| Opus 5.5 | $0.00011 | $0.00168 |
| Sonnet 5.5 | $0.00006 | $0.00084 |
| Haiku 4.5 | $0.00003 | $0.00042 |
Grade A, and why
coding-standards 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
Coding Standards & Best Practices
Universal coding standards applicable across all projects. Detailed patterns and examples are in the references/ directory.
Quick Decision Guide
| What you need | Reference file |
|---|---|
| Naming, immutability, types, error handling, async | references/typescript-patterns.md |
| Components, hooks, state, memoization, lazy loading | references/react-patterns.md |
| REST API design, file structure, testing, code smells | references/api-testing-patterns.md |
Categories
TypeScript/JavaScript Patterns
Variable and function naming conventions, immutability (critical), comprehensive error handling, async/await best practices, type safety, comments/documentation style, and database query performance.
See: references/typescript-patterns.md
React Patterns
Functional component structure with typed props, custom hooks (useDebounce pattern), proper state updates with functional setters, conditional rendering without ternary chains, useMemo/useCallback memoization, and lazy loading with Suspense.
See: references/react-patterns.md
API Design, Testing & Code Smells
REST conventions, consistent ApiResponse format, Zod input validation, project file organization and naming, AAA test pattern, descriptive test naming, and anti-pattern detection (long functions, deep nesting, magic numbers).
See: references/api-testing-patterns.md
Core Principles
- Readability First -- self-documenting code over comments
- KISS -- simplest solution that works
- DRY -- extract and reuse common logic
- YAGNI -- build only what is needed now
- Immutability -- never mutate; always spread
What ships with it
3 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.

coding-standards is a skill published in the GitHub repository cloudnative-co/claude-code-starter-kit (153 stars, last pushed 5d ago), licensed MIT. It adds 28 tokens to every session and 420 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.
