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.

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 | $0.00035 | $0.03119 |
| Opus 5 | $0.00017 | $0.01559 |
| Sonnet 5 | $0.00007 | $0.00624 |
| Haiku 4.5 | $0.00003 | $0.00312 |
Grade A, and why
coding-standards scanned grade A with 1 finding 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 2d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

92% identical to coding-standards — 2 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Coding Standards & Best Practices
Baseline coding conventions applicable across projects.
This skill is the shared floor, not the detailed framework playbook.
- Use
frontend-patternsfor React, state, forms, rendering, and UI architecture. - Use
backend-patternsorapi-designfor repository/service layers, endpoint design, validation, and server-specific concerns. - Use
rules/common/coding-style.mdwhen you need the shortest reusable rule layer instead of a full skill walkthrough.
When to Activate
- Starting a new project or module
- Reviewing code for quality and maintainability
- Refactoring existing code to follow conventions
- Enforcing naming, formatting, or structural consistency
- Setting up linting, formatting, or type-checking rules
- Onboarding new contributors to coding conventions
Scope Boundaries
Activate this skill for:
- descriptive naming
- immutability defaults
- readability, KISS, DRY, and YAGNI enforcement
- error-handling expectations and code-smell review
Do not use this skill as the primary source for:
- React composition, hooks, or rendering patterns
- backend architecture, API design, or database layering
- domain-specific framework guidance when a narrower ECC skill already exists
Code Quality Principles
1. Readability First
- Code is read more than written
- Clear variable and function names
- Self-documenting code preferred over comments
- Consistent formatting
2. KISS (Keep It Simple, Stupid)
- Simplest solution that works
- Avoid over-engineering
- No premature optimization
- Easy to understand > clever code
3. DRY (Don't Repeat Yourself)
- Extract common logic into functions
- Create reusable components
- Share utilities across modules
- Avoid copy-paste programming
4. YAGNI (You Aren't Gonna Need It)
- Don't build features before they're needed
- Avoid speculative generality
- Add complexity only when required
- Start simple, refactor when needed
TypeScript/JavaScript Standards
Variable Naming
What ships with it
1 file 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.
- 2d ago First seen · 550 lines · 35 tokens per session scan A 924693e72547
coding-standards is a skill published in the GitHub repository ysyecust/everything-claude-code (43 stars, last pushed 15d ago), licensed MIT. It adds 35 tokens to every session and 3,119 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). It is 92% identical to coding-standards, differing in 2 lines, and is treated as a copy.

systematic-debugging
Use when encountering any bug, test failure, or unexpected behavior, before proposing fixes.
brainstorming
You MUST use this before any creative work - creating features, building components, adding functionality, or modifying behavior. Explores user intent, requirements and design before implementation.
auto-perf-optimize
Run agent-driven VS Code performance or memory investigations. Use when asked to launch Code OSS, automate a VS Code scenario, run the Chat memory smoke runner, capture renderer heap snapshots, take workflow screenshots, compare run summaries, or drive a repeatable scenario before heap-snapshot analysis.
