plugin-store CLAUDE.md

A contributor guide for Plugin Store, a command-line marketplace that installs, updates, and removes add-ons for several coding agents. It describes the Rust build and test commands and how plugins move from a registry into an agent.

In plain words
What is it for?
Use it when building or testing the Rust project, tracing plugin data flow, or changing how skills, MCP server settings, binaries, and installed-plugin records are handled.
Why use it?
It helps contributors understand the project’s architecture and the path from plugin discovery to installation. This reduces mistakes when changing support for skills, MCP servers, binaries, or stored installation state.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

plugin-store CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Project Overview

Plugin Store — a CLI marketplace for installing/uninstalling/updating Skills and MCP servers across Claude Code, Cursor, and OpenClaw.

Build & Test

cargo build                          # Debug build
cargo build --release                # Release build
cargo test                           # Run all tests
cargo test <test_name>               # Run a single test
cargo test --test integration_test   # Run only integration tests

Architecture

Data Flow

Registry (GitHub JSON) → Cache (/.plugin-store/cache/) → Plugin selection → Agent detection → Component installation (skill/mcp/binary) → State tracking (/.plugin-store/installed.json)

Plugin Model

Each plugin (registry::models::Plugin) has three optional components:

  • Skill — a SKILL.md file downloaded from a GitHub repo, written into the agent's skill directory
  • MCP — an MCP server config (npm/pip/binary) injected into the agent's settings JSON
  • Binary — a platform-specific binary downloaded from GitHub releases with optional checksum verification

Agent Adapter Pattern

agent::AgentAdapter trait defines how plugins integrate with each supported agent. Each adapter (claude_code, cursor, openclaw) implements detection, skill directory resolution, and MCP config read/write for its agent's config format. detect_agents() probes all adapters and returns which are available.

State Tracking

state::InstalledState persists to ~/.plugin-store/installed.json. Each installed plugin records which agents it was installed to, with per-agent paths (skill_path, mcp_key, binary_path) for clean uninstall.

CLI Dispatch

main.rs uses clap derive to parse commands → dispatches to commands::<name>::execute(). Each command handler orchestrates registry fetching, user interaction (via dialoguer), and installer calls. The install command supports --skill-only, --mcp-only, and --agent flags to skip interactive selection.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
