Agentic Plugin Marketplace

> Production-ready agentic workflow building blocks: 91 plugins, 202 agents,
> 180 skills, 105 commands — built for Claude Code and consumed natively by
> OpenAI Codex CLI, Cursor, OpenCode, Gemini CLI, and GitHub Copilot from a single Markdown source.

Quick start

Pick your harness:

Claude Code

/plugin marketplace add wshobson/agents
/plugin install python-development          # or any of 91 plugins

→ Full Claude Code setup, troubleshooting, and plugin catalog

Codex CLI · Cursor · OpenCode · Gemini CLI · Copilot

Codex and Cursor install natively from the committed registries (which point at the source plugins/):

npx codex-marketplace add wshobson/agents        # Codex; then install individual plugins
# Cursor: add the marketplace, then `/plugin install <name>` (reads .cursor-plugin/ + source)

Gemini and OpenCode install via clone + generate (the transformed trees are gitignored):

gh repo clone wshobson/agents ~/agents && cd ~/agents
make generate HARNESS=gemini && gemini extensions install .   # Gemini
make install-opencode                                          # OpenCode (runs generate + symlinks)

Setup details and per-harness gotchas: docs/harnesses.md. Gemini-specific setup: GEMINI.md (also auto-loaded by Gemini CLI).

How it works

Each plugin is isolated and composable: agents, commands, and skills are auto-discovered
from directory structure. **Installing a plugin loads only its components into
context** — not the whole marketplace.

plugins/python-development/
├── .claude-plugin/plugin.json
├── agents/             # 3 Python agents (python-pro, django-pro, fastapi-pro)
├── commands/           # 1 scaffolding command
└── skills/             # 16 specialized skills (async, testing, packaging, …)

Tiered model strategy:

Multi-harness support

This marketplace ships to five agentic harnesses from one Markdown source. Each adapter
emits harness-native artifacts (not lowest-common-denominator translations):

make generate-all                        # all five
make validate                            # structural checks
make garden                              # drift / dead-link / cap detection

Codex and Cursor install from source via committed registries; Gemini and OpenCode install via clone + make.

Quality evaluation

<code class="ra0-md-code">plugin-eval</code> is a three-layer evaluation framework for measuring
and certifying plugin/skill quality:

• Static — deterministic structural analysis (<2s, free)
• LLM Judge — semantic evaluation across 4 dimensions (~30s, Haiku + Sonnet)
• Monte Carlo — statistical reliability via 50-100 simulated runs (~2-5 min)

uv run plugin-eval score path/to/skill --depth quick
uv run plugin-eval certify path/to/skill

→ PluginEval framework documentation

Documentation map

Detail lives in docs/. Read in this order:
