coding-standards

A shared set of coding rules covering naming, immutability, readability, small functions, file size, and error handling.

In plain words
What is it for?
Use it when starting modules, reviewing or refactoring code, enforcing conventions, or setting up linting and type checks.
Why use it?
It gives projects a consistent baseline for maintainable code and makes reviews and onboarding clearer.

Token cost

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.

Security

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 yesterday.

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.

Coding Standards & Best Practices

Baseline coding conventions applicable across projects.

This skill is the shared floor, not the detailed framework playbook.

  • Use frontend-patterns for React, state, forms, rendering, and UI architecture.
  • Use backend-patterns or api-design for repository/service layers, endpoint design, validation, and server-specific concerns.
  • Use rules/common/coding-style.md when 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

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 artttj/rapid-stack (2 stars, last pushed 1mo ago), licensed MIT. It adds 46 tokens to every session and 3,118 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 86% identical to coding-standards, differing in 6 lines, and is treated as a copy.
