Agentic Plugin Marketplace

Production-ready agentic workflow building blocks: 82 plugins, 191 agents, 155 skills, 102 commands — built for Claude Code and consumed natively by OpenAI Codex CLI, Cursor, OpenCode, and Gemini CLI from a single Markdown source.

[!NOTE] One source-of-truth (plugins/), five harnesses. Each harness gets idiomatic, harness-native artifacts — not lowest-common-denominator translations. See docs/harnesses.md for the capability matrix.

Quick start

Pick your harness:

Claude Code

/plugin marketplace add wshobson/agents
/plugin install python-development          # or any of 82 plugins

→ Full Claude Code setup, troubleshooting, and plugin catalog

Codex CLI · Cursor · OpenCode · Gemini CLI

gh repo clone wshobson/agents ~/agents
cd ~/agents
make generate HARNESS=<codex|cursor|opencode|gemini>

Per-harness setup guides: CODEX.md · CURSOR.md · OPENCODE.md · GEMINI.md

What's inside

	Count	What it is
Plugins	82	Granular, single-purpose installable units (81 local + 1 external via git-subdir)
Agents	191	Domain experts (architecture, languages, infra, security, data, ML, docs, business, SEO)
Skills	155	Modular knowledge packages with progressive disclosure (load when activated)
Commands	102	Slash commands: scaffolding, security scans, test gen, infrastructure setup
Orchestrators	16	Multi-agent coordination workflows (full-stack, security, ML, incident response)

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, …)

Three-tier model strategy:

Tier	Model	Use
1	Opus 4.7	Architecture, security, code review, production-critical
2	inherit	User-chosen — backend, frontend, AI/ML, specialized
3	Sonnet	Docs, testing, debugging, API references
4	Haiku	Fast operational tasks, SEO, deployment, content

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):

Harness	Generates	Notes
Claude Code	(source-of-truth)	Native marketplace.json + plugins/
Codex CLI	.codex/skills/, .codex/agents/, AGENTS.md	8 KB skill cap respected; commands → skills
Cursor	.cursor-plugin/, .cursor/rules/	Thin marketplace + curated rules; reuses .claude/
OpenCode	.opencode/agents/, .opencode/commands/	permission: block from tools: allowlist
Gemini CLI	skills/, agents/, commands/ (TOML)	Native skills + subagents (April 2026 spec)

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

Quality evaluation

plugin-eval 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
