Production-grade guidance for writing, reviewing, and maintaining high-quality SKILL.md files across the entire agent ecosystem.
This plugin provides the canonical reference for creating skills that activate reliably in Claude Code, Cursor, Codex, OpenCode, Kiro, Gemini CLI, and other tools that support the Agent Skills standard.
- Teaches current skill design: short trigger descriptions tested with trigger evals, bodies that carry only what the agent would otherwise get wrong, constraints with reasons, progressive disclosure into
references/, scripts for deterministic work - Helps you write new skills from scratch
- Reviews and improves existing skills with specific, actionable feedback
- Ensures compatibility with
agnixlinting and the broader agentsys ecosystem

- Triggerable: the description says when to use the skill, and a trigger eval confirms it
- Lean: they carry what the agent lacks and leave out what it knows
- Explained: constraints come with reasons, so the agent handles cases the rule did not foresee
- Cross-tool: they follow the Agent Skills spec and say what to do when a tool is missing
- Maintainable: they pass
