Guidance for AI coding agents (Claude Code, Codex, Warp, etc.) working in this repository.
A Claude Code / OpenCode skill implemented entirely as Markdown. The runtime artifact is SKILL.md: the agent reads its YAML frontmatter (metadata + allowed tools) followed by the editor prompt. There is no build step and no code to run.
SKILL.md — the skill itself. YAML frontmatter (name, version, description, allowed-tools) followed by the canonical, numbered pattern list with before/after examples. This is the source of truth.README.md — for humans: installation, usage, a summary table of the patterns, and a version history.SKILL.md and README.md must stay in sync. When you change behavior or content:
SKILL.md frontmatter has a version: field and README.md has a "Version History" section. Bump both together.
