Claude Plugins

Experiments (claude-probe, skill-catalog-routing, subagent-compaction) live under experiments/, each exposed as a just module.

A curated collection of 47 Claude Code plugins providing 400+ skills and 22 agents for development workflows.

The same skills, subagents and safety hooks also run in OpenCode, pi and Antigravity CLI. Skills are read in place from a checkout of this repo, so a skill edit reaches every harness without a copy step; subagents and hooks are exported to each tool's own format. Browse everything in the plugin catalog.

Supported harnesses

Harness	Skills	Subagents	Safety hooks
Claude Code	Native plugin marketplace	Native	Native
OpenCode	Skill adapter: a search_skills tool plus the top 5 matches injected each turn	Exported to OpenCode's agent format	Exported as OpenCode JS plugins
pi	Skill adapter (same as OpenCode)	Exported for @tintinweb/pi-subagents	Run by a generated pi extension
Antigravity CLI	Plugin skill dirs registered in place in skills.json	Exported to agents/<name>/agent.md	Run by a generated hooks.json runner

OpenCode and pi both read SKILL.md unmodified, but neither budgets its skill listing: listing 382 skills natively measured ~34,000 tokens of context on every turn (2026-08-24). The adapter (ADR-0022, adapters/) reaches all of them for ~600.

Claude Code

Add the marketplace, then install the plugins you want:

claude plugin marketplace add laurigates/claude-plugins
claude plugin install git-plugin@laurigates-claude-plugins
claude plugin install python-plugin@laurigates-claude-plugins

Inside a session, /plugin browses and installs the same plugins.

OpenCode

Needs a clone of this repo, bun and just:

git clone https://github.com/laurigates/claude-plugins && cd claude-plugins
(cd adapters && bun install)
just setup-opencode

setup-opencode installs the subagents and hook plugins into ~/.config/opencode and writes an opencode.json that registers the adapter for a local MLX model. An existing opencode.json is kept (a sample is written beside it); wire the adapter into it with just oc-adapter-register. Details: docs/opencode-export.md.

pi

Needs a clone of this repo, bun and just:

git clone https://github.com/laurigates/claude-plugins && cd claude-plugins
(cd adapters && bun install)
just setup-pi

setup-pi registers the adapter in ~/.pi/agent/settings.json, installs the subagents and the safety-hook extension, and prints the steps to serve a local model. just pi-adapter-unregister reverses the registration. Details: docs/pi-export.md.

Antigravity CLI

Needs a clone of this repo, just and Python 3:

git clone https://github.com/laurigates/claude-plugins && cd claude-plugins
just setup-antigravity

setup-antigravity adds each plugin's skills/ directory to ~/.gemini/config/skills.json, and installs the subagents and the safety-hook runner into ~/.gemini/config. Existing entries in skills.json and hooks.json are kept. just unconfigure-antigravity removes the skill registrations, and just agy-check reports what is installed. Details: docs/antigravity-export.md.

Getting Started

1. Install the plugins for your harness, above
2. Run a health check — /health-plugin:health-check then /health-plugin:health-audit to diagnose your setup and get plugin recommendations for your stack
3. Follow the tiered setup — The Plugin Map provides a recommended install order (Tier 0 foundation through Tier 3+ stack-specific), decision trees, and project presets

For MCP servers, /configure-plugin:configure-mcp sets them up interactively.

Design Principles

The methodology behind these plugins — what a probabilistic agent should decide versus what a deterministic substrate should verify and remember. See docs/PRINCIPLES.md for the full set, each grounded in the rules, skills, and hooks that embody it.

Prerequisites

• Bash 5+ — Required for shell scripts. macOS ships Bash 3.2; install via brew install bash.

Questions and Ideas

Discussions is the place to ask things in the open:

Category	For
Q&A	How do I do X, why does a skill behave this way, is Z supported
Ideas	A plugin or skill you would like to exist, before it is a concrete request
Show and tell	What you built with these plugins

Use issues for a defect or a concrete feature request, and please do not open a pull request just to ask a question.

Development

Plugins use release-please for automated versioning. Use conventional commits to trigger releases:

feat(git-plugin): add worktree support    # minor bump
fix(python-plugin): handle empty venv     # patch bump

See CLAUDE.md for detailed development instructions.
