context7-latest-usage
Fetch the latest, docs-grounded API details and best practices for a library/framework using Context7 MCP tools `resolve-library-id` and `get-library-docs`. Use when a user asks for “最新用法/最新寫法/最佳實務/latest usage/current best practice/latest API” of a package, or asks how to implement a feature with a library and wants the newest docs-based guidance.
When & Why to Use This Skill
The Context7 Latest Usage skill empowers developers to access real-time, documentation-grounded API details and best practices for any library or framework. By integrating with Context7 MCP tools, it bypasses LLM training data limitations to provide the most current library usage, verified code snippets, and official citations, ensuring your implementation follows the latest industry standards and avoids deprecated patterns.
Use Cases
- Upgrading legacy codebases: Quickly identify breaking changes and migration paths when moving to the latest version of a framework like React, Next.js, or FastAPI.
- Implementing new features: Retrieve the most current syntax and best practices for specific library functions to ensure high-quality, performant, and secure code.
- Verifying API signatures: Eliminate LLM hallucinations by fetching verified API parameters, default values, and return types directly from official documentation.
- Environment-specific setup: Get tailored installation and configuration guidance based on your specific runtime (e.g., Node.js 20, Python 3.12) and package manager.

Context7 Latest Usage
Workflow
1) Clarify the target library and environment
- Extract the library/framework name and ecosystem (npm/pip/cargo/go/etc).
- Extract language + runtime (e.g., Node.js 20, Python 3.12) and any required version constraints.
- Extract the user’s intent (which feature/task they want to build).
- If any of these are missing or ambiguous, ask a brief clarification question before calling Context7.
2) Resolve the library identifier (Context7)
- Call Context7 MCP tool
resolve-library-idwith the library name (and ecosystem if supported). - If multiple candidates are plausible, pick the best match and confirm with the user.
3) Fetch the newest relevant docs (Context7)
- Call Context7 MCP tool
get-library-docsfor the resolved id, scoped to the user’s task. - Prefer latest stable docs; include migration notes if the user is upgrading.
- If the docs are large, fetch only the sections needed (install, quickstart, the specific API symbols, config, and pitfalls).
4) Produce the response in a fixed format
Return exactly:
- Up-to-date API / best practices: concise bullet summary grounded in the fetched docs
- Copy-paste snippet: tailored to the user’s language/runtime/version, includes minimal setup
- Sources: Context7-provided citations/links for every important claim (especially API signatures, defaults, and behavior)
5) Failure handling (no guessing)
- If Context7 MCP tools are unavailable or any call fails, say so clearly and ask the user to enable Context7 MCP or paste/link the docs.
- Do not provide “latest API” claims without sources from Context7 output.
