awesome-ai-agent-skills: Instructions file for Claude Code

AI Agent Instructions

This repository is a community-shared, tool-agnostic skill library for AI coding agents.

CLAUDE.md is the tracked instruction source and AGENTS.md points to it by symlink; preserve that relationship.

Skill Authoring

Author each skill under skills/<skill-name>/:

skills/<skill-name>/
  SKILL.md
  references/   # optional
  assets/       # optional
  scripts/      # optional

• Use kebab-case for the folder and frontmatter name.
• Every SKILL.md requires YAML frontmatter with name and description; do not add author.
• Write actionable workflows for a specific problem, with references for details that do not belong in the main skill.
• Keep guidance compatible across agent tools unless the capability is inherently tool-specific.

Neutral Skill Editing

When reviewing, creating, or updating a skill under skills/:

• Treat the target skill as an artifact; do not execute it merely because it is being edited.
• Do not load or follow sibling repository skills during the edit.
• Base changes on the user request, repository instructions, the target skill's intended behavior, relevant source files, and repository validators.
• Inspect another skill only when the user explicitly requests a comparison, without activating it.
• Repository scripts such as npm run sync and npm run validate remain authoritative.

Canonical Sources And Generated Outputs

• Author skill content only in skills/<skill-name>/.
• Use plugin-groups.json for marketplace ownership and each plugin's name, displayName, description, skill membership, and required multi-skill Codex defaultPrompts. Multi-skill prompts must route without assuming the first listed skill always applies.
• Assign every skill to exactly one plugin group; merge overlapping skills instead of duplicating membership.
• Use scripts/lib/plugin-shape.js as the sole definition of generated marketplace and manifest shapes.
• Treat .claude-plugin/marketplace.json, .agents/plugins/marketplace.json, generated README tables, and plugins/** as npm run sync outputs.
• Never edit plugins/<plugin-name>/** directly. Each generated package must contain its bundled skills plus .claude-plugin/plugin.json and .codex-plugin/plugin.json; the Codex manifest uses skills: "./skills/".
• Do not add marketplace or manifest keys until they have been validated against the oldest supported Claude Code. Claude rejects unknown keys, so preserve the shapes emitted by scripts/lib/plugin-shape.js.
