agent-skills
A small collection of Agent Skills shipped through Claude Code, Codex, and Gemini CLI from one canonical source. Each skill lives in its own root folder with SKILL.md as the source of truth; per-agent adapters point back at it so there is no drift across runtimes.
Skills
| Skill | Path | Summary | |-------|------|---------| | deep-documentation | deep-documentation/SKILL.md | Create, expand, reorganize, and maintain repository documentation with deep coverage: READMEs, browsable docs, API/reference pages, llms.txt / llms-full.txt, changelogs, and repo-local agent skills. Use when you want comprehensive docs, LLM-friendly indexes, documentation that stays in sync with code, or guidance for future models on how to use the project. | | truthful-coder | truthful-coder/SKILL.md | Strict change transparency while editing code, notebooks, configs, or running commands: announce intent, track what actually changed, and disclose every delta (including formatters, lockfiles, and incidental edits). Use when you want no "hidden" repo or environment changes. |
Install
The recommended path for Claude Code is the plugin marketplace:
/plugin marketplace add adamdroberts/agent-skills
/plugin install deep-documentation@adamdroberts-skills
/plugin install truthful-coder@adamdroberts-skillsThe marketplace name is adamdroberts-skills (the literal agent-skills is reserved by Anthropic). Updates ride on git commits — re-run /plugin marketplace update adamdroberts-skills to pull the latest.
Codex can also add this repository as a plugin marketplace:
codex plugin marketplace add adamdroberts/agent-skillsThen use the Codex TUI Plugins panel to install deep-documentation or truthful-coder. For Gemini CLI, project-scoped installs, and direct use without an agent runtime, see docs/install.md.
Agent support
| Agent | Adapter | Notes | |-------|---------|-------| | Claude Code (marketplace) | .claude-plugin/marketplace.json + per-plugin plugin.json | Each skill is its own plugin under marketplace adamdroberts-skills; "skills": ["./"] loads the root SKILL.md directly. | | Claude Code (project) | .claude/skills/ | Symlinks to the canonical root skill folders. Loaded via --add-dir or copied into another project's .claude/skills/. | | Codex (plugin marketplace) | .agents/plugins/marketplace.json + plugins/ | Codex-native plugin metadata; each plugin exposes a skills/ symlink back to the canonical root folder. | | Codex (repository skills) | .agents/skills/ | Symlinks to the canonical root skill folders. Codex discovers repository skills from .agents/skills and follows symlinks. | | Gemini CLI | .gemini/agents/ | Markdown wrappers (not symlinks) because Gemini does not natively load SKILL.md. The wrapper reads the canonical SKILL.md at runtime. |
Documentation
- docs/ — browsable documentation set.
- docs/install.md — every install path, per agent.
- docs/architecture.md — repo layout, the canonical-folder + adapter pattern, Mermaid diagram of how the distribution paths share one source.
- docs/contributing.md — step-by-step guide for adding a new skill end-to-end (canonical folder, five adapters, plugin manifests, marketplace entries, validation).
- CHANGELOG.md — append-only history.
- llms.txt and llms-full.txt — LLM-oriented index and bundled documentation set for ingestion.
Status
Stable. Two skills, five install paths across Claude Code, Codex, and Gemini CLI, with no breaking changes planned. New skills follow the contribution checklist in docs/contributing.md.
