Pre-flight Dependencies (auto-injected by Plugin Store CI)

Run once per session before first use. These checks ensure required tools are installed.

Plugin Store

A CLI marketplace for installing/uninstalling/updating Skills and MCP servers across Claude Code, Cursor, and OpenClaw. Also an open-source community platform where any developer can submit plugins.

Pre-flight Checks

Run once per session before the first plugin-store command. Do not echo routine output to the user.

1. Check binary version

plugin-store --version 2>/dev/null || ~/.local/bin/plugin-store --version 2>/dev/null || ~/.cargo/bin/plugin-store --version 2>/dev/null

• If the reported version is ≥ 0.3.0 (this skill's metadata.version): binary is current, skip to step 2.
• If the binary is missing or older: run the installer.

Manual install — visit https://github.com/okx/plugin-store/releases, download the binary for your platform, verify it against checksums.txt from the same release, and place it on your PATH (e.g. ~/.local/bin/plugin-store).

Offline fallback: if a binary already exists locally, proceed with it. If not installed and the network is unreachable, stop and ask the user to check their connection.

2. Check for Skill update (remote version check)

Fetch the latest Skill version from GitHub (timeout 5 seconds, non-blocking):

curl -sSL --max-time 5 "https://raw.githubusercontent.com/okx/plugin-store/main/skills/plugin-store/SKILL.md" 2>/dev/null | head -20 | grep 'version:' | head -1

Compare the remote metadata.version with the local version (0.3.0).

If remote version is newer than local, display this notice to the user:

📦 Plugin Store Skill 有新版本可用（当前: 0.3.0, 最新: X.Y.Z）

是否更新？更新命令：

plugin-store install plugin-store --agent claude-code --skill-only

⚠️ 注意：更新后需要重启当前会话，新版 Skill 才会在上下文中生效。

Then wait for the user's response:

• If user says yes / 确认 / 更新 → run the install command, then remind: "Skill 已更新，请重启当前会话（退出并重新进入）以加载新版本。"
• If user says no / 跳过 / 以后再说 → continue with current version, do not ask again this session.
• If the curl fails or times out → skip silently, continue with current version.

If versions match or remote is unreachable, skip silently — do not print anything.

3. Do not auto-reinstall on command failures

Report errors and suggest plugin-store self-update or checking https://github.com/okx/plugin-store.

4. Install onchainos-skills (silent, non-blocking)

npx skills add okx/onchainos-skills --yes 2>/dev/null || true

This installs sub-skills used by Skill Routing (okx-dex-token, okx-dex-swap, etc.). Do not block on failure.

Available Plugins

Always run plugin-store list to get the current plugin list — never rely on a hardcoded table.

plugin-store list

Parse the output and present it to the user as a clean table (name, category, downloads, description). The registry updates dynamically; this is the only source of truth.

User Commands

Developer Commands

Operation Flow

Intent: Strategy / DApp / Capability Discovery

1. Run plugin-store list to fetch the live registry
2. Present results as a clean table (name, category, downloads, description)
3. Suggest next steps: "Want to install one? Just say install <name>"

Intent: Install a Plugin

1. Run plugin-store install <name> --yes
   • --yes skips the community plugin confirmation prompt
   • Agent selection is automatic in non-interactive mode (installs to all detected agents)
2. The CLI will:
   • Fetch plugin metadata from registry
   • Download and install skill, MCP config, and/or binary as applicable
3. Immediately after install succeeds, read the installed skill file directly — do NOT ask the user to restart:

   Read file: ~/.claude/skills/<name>/SKILL.md
   

   Then follow the instructions in that file (Pre-flight → onboarding flow). The skill is immediately usable in the current session.

Intent: Manage Installed Plugins

1. Run plugin-store installed to show current state
2. Run plugin-store update --all to update everything
3. Run plugin-store uninstall <name> to remove

Developer Workflow: Create and Submit a Plugin

Plugin Store is an open-source community platform. Any developer can submit a plugin through a Pull Request. The full workflow:

Overview

Two types of plugins:
  Type A: Pure Skill — just a SKILL.md that orchestrates onchainos CLI commands
  Type B: Skill + Source Code — SKILL.md + a CLI tool compiled/installed from your source repo

Five supported languages for source code:
  Rust, Go         → compiled to native binary (~1-20MB)
  TypeScript, Node.js → distributed via npm install (~KB)
  Python           → distributed via pip install (~KB)

Step 1: Fork and scaffold

# Fork https://github.com/okx/plugin-store on GitHub, then:
git clone --depth=1 git@github.com:YOUR_USERNAME/plugin-store.git
cd plugin-store
plugin-store init <your-plugin-name>

This creates skills/<your-plugin-name>/ with a complete template:

skills/<your-plugin-name>/
├── plugin.yaml           # Plugin manifest (fill in your details)
├── skills/<name>/
│   └── SKILL.md          # Skill definition (built-in onchainos demo)
│   └── references/
├── LICENSE
├── CHANGELOG.md
└── README.md

Step 2: Edit plugin.yaml

Pure Skill — just fill in the basics:

schema_version: 1
name: <your-plugin-name>          # lowercase + hyphens, 2-40 chars
version: "1.0.0"
description: "What your plugin does"
author:
  name: "Your Name"
  github: "your-github-username"  # must match PR submitter
license: MIT
category: utility                 # trading-strategy | defi-protocol | analytics | utility | security | wallet | nft
tags: [keyword1, keyword2]

components:
  skill:
    dir: skills/<your-plugin-name>

api_calls: []                     # external API domains your plugin calls

Skill + Source Code — add a build section pointing to your source repo:

# ... same as above, plus:
build:
  lang: rust                           # rust | go | typescript | node | python
  source_repo: "your-org/your-tool"    # your GitHub repo with source code
  source_commit: "a1b2c3d4e5f6..."     # full 40-char commit SHA (git rev-parse HEAD)
  binary_name: "your-tool"             # compiled output name
  # main: "src/index.js"              # required for typescript/node/python

How to get the commit SHA:

cd your-source-repo
git push origin main
git rev-parse HEAD     # copy this 40-char string into build.source_commit

Step 3: Write SKILL.md

SKILL.md teaches the AI agent how to use your plugin. Required sections:

1. YAML frontmatter — name, description, version, author, tags
2. Overview — what the plugin does (2-3 sentences)
3. Pre-flight Checks — what needs to be installed before use
4. Commands — specific onchainos commands with When to use / Output
5. Error Handling — table of common errors and resolutions
6. Skill Routing — when to defer to other skills

Critical rule: All on-chain write operations (signing, broadcasting, swaps, contract calls) MUST use onchainos CLI. Querying external data sources (third-party APIs, price feeds) is freely allowed.

Step 4: Validate locally

plugin-store lint ./skills/<your-plugin-name>/

Fix all errors (❌), then re-run until you see ✓. Warnings (⚠️) are advisory.

Step 5: Submit via Pull Request

git checkout -b submit/<your-plugin-name>
git add skills/<your-plugin-name>/
git commit -m "[new-plugin] <your-plugin-name> v1.0.0"
git push origin submit/<your-plugin-name>

Then create a PR from your fork to okx/plugin-store. Each PR must contain exactly one plugin.

What happens after submission

Phase 2: Structure check (~30s) — bot validates plugin.yaml + SKILL.md
Phase 3: AI code review (~2min) — Claude reads your code, writes a 9-section report
Phase 4: Build check (if binary) — compiles your source code on 3 platforms
Phase 7: After merge — auto-publishes to registry, users can install immediately

Human review takes 1-3 days. Once merged, your plugin is live:

plugin-store install <your-plugin-name>

Skill Self-Update

To update this skill to the latest version:

macOS / Linux:

plugin-store install plugin-store --agent claude-code --skill-only

Or re-install manually — see Manual install in section 1 above (download the binary from the GitHub releases page and verify it against checksums.txt).
