Coding Patterns

This skill is a concise playbook for agents writing or reviewing code. It complements workflow-guardrails (which governs process and discipline) with language-aware advice on design, testing, and idioms.

Scope:

• cross-language design heuristics
• honest testing and verification patterns
• Python dos and donts
• TypeScript / JavaScript dos and donts

Non-scope:

• deep style guides, lint rule catalogs, or full framework tutorials
• anything already enforced by the project's linter, formatter, or type checker
