context7

从Context7获取最新版的库文档与代码示例。在使用任何编程库或框架时，若需要最新的API文档、使用示例，或特定版本的文档资料，即可使用此技能。当用户询问某库的API、需要某特定库的代码示例、以库名或框架名进行引用，或在编写代码前需验证当前库的行为时，此技能便会自动触发。

  Retrieve up-to-date library documentation and code examples from Context7.
  Use when working with any programming library or framework and you need
  current API docs, usage examples, or version-specific documentation.
  Triggers: user asks about a library API, needs code examples for a specific
  library, references a package/framework by name, or you need to verify
  current library behavior before writing code.

Context7

Fetch version-specific documentation and code examples for any programming library directly from source repositories.

Workflow

1. Resolve library ID

bash
bun ~/.claude/skills/context7/context7.ts resolve-library-id \
  --query "<what the user needs>" \
  --library-name "<library name>"

Returns a Context7-compatible library ID (e.g., /vercel/next.js, /mongodb/docs).

Skip this step if the user provides an ID in /org/project format.

2. Query documentation

bash
bun ~/.claude/skills/context7/context7.ts query-docs \
  --library-id "<id from step 1>" \
  --query "<specific question>"

Example

bash
# Find the library ID for React
bun ~/.claude/skills/context7/context7.ts resolve-library-id \
  --query "useEffect cleanup function" --library-name "react"

# Query docs with the returned ID
bun ~/.claude/skills/context7/context7.ts query-docs \
  --library-id "/facebook/react" \
  --query "How to use useEffect cleanup function"

Constraints

  • •Call each command at most 3 times per question.
  • •Never include sensitive data (API keys, passwords) in queries.
  • •Be specific in --query — prefer "How to set up JWT auth in Express" over "auth".
