Context Hub Skill

Use chub as a fast retrieval layer for third-party API/SDK integration docs.

When to Use This Skill

Triggered by:

• "查某个 SDK 的最新用法"
• "这个第三方 API 怎么接"
• "给我某库某版本的示例代码"
• "查文档并按语言返回"
• "搜索某个 provider 的文档条目"

Prerequisites

1. Install Node.js and npm
2. Install chub manually:

HTTP_PROXY=http://127.0.0.1:7897 HTTPS_PROXY=http://127.0.0.1:7897 npm install -g --prefix "$HOME/.local" @aisuite/chub
export PATH="$HOME/.local/bin:$PATH"

3. Verify:

chub --cli-version

Routing Policy

1. OpenAI tasks in Claude Code: prioritize official OpenAI docs first (developers.openai.com / platform.openai.com).
2. Non-OpenAI tasks: prioritize chub.
3. If chub has no matching entry, fallback to official vendor docs or source code.

Core Workflow

1. Search the registry:

HTTP_PROXY=http://127.0.0.1:7897 HTTPS_PROXY=http://127.0.0.1:7897 chub search "<query>" --limit 10

2. Fetch the doc/skill entry with language/version:

HTTP_PROXY=http://127.0.0.1:7897 HTTPS_PROXY=http://127.0.0.1:7897 chub get <id> --lang py
HTTP_PROXY=http://127.0.0.1:7897 HTTPS_PROXY=http://127.0.0.1:7897 chub get <id> --lang js --version <version>

3. Pull references when needed:

HTTP_PROXY=http://127.0.0.1:7897 HTTPS_PROXY=http://127.0.0.1:7897 chub get <id> --file references/<file>.md
HTTP_PROXY=http://127.0.0.1:7897 HTTPS_PROXY=http://127.0.0.1:7897 chub get <id> --full

4. Use --json when downstream parsing is required.

Optional Commands (Explicit User Request Only)

Do not run these by default. Run only when the user explicitly asks:

chub annotate <id> "<note>"
chub feedback <id> up
chub feedback <id> down --label outdated

Guardrails

• Official vendor docs and SDK source code remain the source of truth for high-risk decisions.
• For OpenAI topics, use official OpenAI docs as primary evidence.
• Do not claim behavior that chub output does not show.
• Do not auto-send feedback or annotations without explicit consent.
