AI Plugins Marketplace

Welcome to the AI Plugins Marketplace, a monorepo designed to host, manage, and distribute plugins for various autonomous AI agents.

Supported Agents (Initial)

Initially, this marketplace provides and supports plugins for the following agents:

• Claude Code
• Antigravity
• Qwen
• OpenCode

Installing

This repository is itself a Claude Code marketplace:

claude plugin marketplace add ckir/aiplugins

Working inside a clone of this repository, skip that step: .claude/settings.json declares the marketplace, so claude plugin install resolves it already.

Each plugin's own README then carries its claude plugin install line, along with the prerequisites that plugin needs. The entries resolve to plugin zips on the latest release that already contain the binaries for Windows x64 plus Linux and macOS on x86_64 and aarch64, so nothing is cloned, built, or compiled at install time. The Antigravity and Qwen plugins install through their own agents' mechanisms — again, see their READMEs.

The OpenCode plugins install as file copies — no registry, no build of the TypeScript itself. Per plugin (full steps in its README):

Plugin	Copies	Binary staging
aiplugins-devtools-opencode	skills/* → .opencode/skills/, commands/* → .opencode/command/	none (skills and a command, no binary)
rtk-mcp-opencode	plugin.ts → .opencode/plugins/, skills/* → .opencode/skills/	just build-rtk-mcp-opencode
re-ghidra-mcp-opencode	plugin.ts → .opencode/plugins/, skills/* → .opencode/skills/, agents/* → .opencode/agents/	just build-re-ghidra-mcp-opencode
todov2-opencode	whole folder → .opencode/plugins/todov2-opencode/ (multi-file: plugin.ts, tui.tsx, tool/)	none (pure TypeScript, no binary)

Merge each plugin's opencode.jsonc into .opencode/opencode.jsonc; the ./bin/<name> command in it is relative to the installed plugin copy, so stage the built binary next to that copy's merge target.

Prefer to have an agent do it? Tell it to fetch and follow the install document for the plugin you want — it performs the whole procedure (prerequisites, file copies, dependency, binary, config merge, verification) and asks whether to install project-local or global first:

What each plugin costs a context window

Resident is what the host holds in every request, for the whole session — the MCP tool schemas plus the frontmatter it reads to decide what each skill and agent is for. Invocation loads only when one of them actually runs.

Setup, on OpenCode plugins only. An OpenCode plugin also loads its plugin.ts setup module in-process with the host on every request — a third tier the table above does not include. Each plugin's own page reports it as Setup alongside these two tiers.

Bytes, not tokens. This is the exact serialised size of what the host loads, measured by probing the plugin's own MCP server and reading its skill and agent frontmatter. It is not a token count and does not convert to one at a fixed rate — treat it as a figure you can compare between plugins, not as a context budget.

≥, because hook output is excluded. Measuring it would mean executing the plugin's hooks against a synthetic event, which this tool will not do. A plugin whose hooks emit a large preamble costs more than the figure shown.

Generated by tools/plugin-footprint; regenerate with just footprint-regen.

Repository Structure

This repository is structured as a monorepo. It will contain specialized packages, shared resources, and individual plugins tailored to the agents they support.

shared/ holds engines rather than plugins. A crate belongs there when more than one agent's plugin would otherwise reimplement it — the agent-specific half (manifest, skills, hooks, settings format) stays in that agent's directory and is usually a thin front end.

Crate	What it is
shared/ghidra-ipc	Wire protocol, framing and error envelopes for the Ghidra worker channel
shared/ghidra-worker-ctl	Headless Ghidra JVM lifecycle: boot, launch, connection, Windows Job Object containment
shared/ghidra-mcp	The MCP server and its 19 reverse-engineering tools, plus the embedded Ghidra worker script and driver skill

Fronted by all four agents: claude-code/plugins/re-ghidra-mcp-cc, opencode/plugins/re-ghidra-mcp-opencode, antigravity/plugins/re-ghidra-mcp-agy and qwen/plugins/re-ghidra-mcp-qwen.

shared/devtools/ is not a crate (it is excluded from the Cargo workspace). It holds the canonical copy of the skills that the four aiplugins-devtools-* plugins ship; just emit-devtools-skills copies them into each plugin and just devtools-skills checks them (maintainer notes: shared/devtools/README.md).
