Claude Plugins

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

A curated collection of 49 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

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:

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

OpenCode

Needs a clone of this repo, bun and just:

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:

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:

setup-antigravity adds each plugin's skills/ directory to
~/.gemini/config/skills.json, and installs the subagents…
