Agentic Plugin Marketplace
Production-ready agentic workflow building blocks: 93 plugins, 202 agents, 181 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 93 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)
Setup details and per-harness gotchas: docs/harnesses.md.
What's inside
| Count | What it is | |
|---|---|---|
| Plugins | 93 | Granular, single-purpose installable units (91 local + 2 external via git-subdir) |
| Agents | 202 | Domain experts (architecture, languages, infra, security, data, ML, docs, business, SEO) |
| Skills | 181 | Modular knowledge packages with progressive disclosure (load when activated) |
| Commands | 105 | 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, …)
Tiered model strategy:
| Tier | Model | Use |
|---|---|---|
| 0 | Fable 5 | Longest-horizon autonomous work — large migrations, multi-hour runs (opt-in, premium cost) |
| 1 | Opus | 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 | .agents/plugins/marketplace.json + plugins/*/.codex-plugin/plugin.json (committed); .codex/skills/, .codex/agents/ (gitignored) |
8 KB skill cap respected; commands → skills |
| Cursor | .cursor-plugin/, .cursor/rules/ |
Thin marketplace + curated rules; reuses .claude/ |
| OpenCode | .opencode/agents/, .opencode/commands/, .opencode/skills/ |
permission: block from tools: allowlist; OpenCode-safe skill names |
| Antigravity CLI | .antigravity/plugins/<p>/{skills/,agents/,commands/} |
Self-contained agy plugin per source plugin; model tier alias (inherit/flash/pro) |
| Copilot | .copilot/agents/, .copilot/skills/, .copilot/commands/ |
Markdown agent profiles + SKILL.md skills + commands-as-skills; model maps to native Claude models |
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.

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).
| Harness | Pensyve integration |
|---|---|
| Claude Code | /plugin install pensyve from this marketplace (integrations/claude-code) |
| Codex CLI | integrations/codex-plugin |
| Cursor | integrations/cursor |
| OpenCode | integrations/opencode-plugin |
| Copilot | .copilot/ in repo root or ~/.copilot/ via make install-copilot |
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.
