Agentic Plugin Marketplace

Production-ready agentic workflow building blocks: 94 plugins, 202 agents, 183 skills, 105 commands — built for Claude Code and consumed natively by OpenAI Codex CLI, Cursor, OpenCode, the Antigravity CLI, and GitHub Copilot 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 94 plugins

→ Full Claude Code setup, troubleshooting, and plugin catalog

Codex CLI · Cursor · OpenCode · Antigravity 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)

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

gh repo clone wshobson/agents ~/agents && cd ~/agents
make generate HARNESS=antigravity && make install-antigravity  # Antigravity (agy)
make install-opencode                                          # OpenCode (runs generate + symlinks)

Skills only: gh skill · npx skills

Both Agent Skills installers read plugins/*/skills/ straight from GitHub, into whichever agent you use. No clone, no marketplace, no generate step. Skills only: no agents, commands, or hooks.

gh skill install wshobson/agents                                 # browse, then pick a skill or --all
gh skill install wshobson/agents python-testing-patterns --agent claude-code
npx skills add wshobson/agents --skill python-testing-patterns   # add -a claude-code, -g for user scope

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; Antigravity and OpenCode install via clone + make. Individual skills install into any agent with gh skill install wshobson/agents or npx skills add wshobson/agents, no clone needed.

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

External Memory Integration

Pensyve is included as an external git-subdir entry for Claude Code. Pensyve also maintains direct upstream integrations for Codex CLI, Cursor, OpenCode, and Copilot (not yet Antigravity CLI).

External Security Integration

HOL Guard is included as an external git-subdir entry for Claude Code from the reviewed distributions/wshobson-agents payload in hashgraph-online/hol-guard-plugin. The payload exposes local hol-guard and plugin-scanner skills. Guard Cloud is neither required nor promoted on the default path. This marketplace entry is a Claude Code discovery surface only; it does not add HOL Guard to this repository's generated Codex, Cursor, OpenCode, Antigravity, or Copilot registries.

The reviewed external payload is pinned to commit 43b2dda59e9f07057c52e69fd7426188faae1488. Its local CLI pins are hol-guard==2.2.119 and plugin-scanner==2.2.119, and installation requires user approval. For a reviewed payload update, the marketplace sha and the matching marketplace/external manifest versions must be advanced together. When protection is explicitly requested, the external hol-guard runtime can modify supported harness hook/settings configuration; those changes are performed by the local Guard CLI, not by files in this marketplace repository.
