MCP Skill: Context7 (Docs Lookup)

Scope

Use the MCP server configured as context7 in .vscode/mcp.json to retrieve documentation context for libraries used in this repo.

Preconditions

• Ensure .vscode/mcp.json contains the context7 server.
• Ensure the CONTEXT7_API_KEY input is available (the VS Code MCP input prompt will request it).

Operating Rules

• Use Context7 for API correctness when there is a meaningful chance memory is wrong (new Angular versions, new NgRx Signals APIs, Firebase SDK changes).
• Prefer primary documentation references; do not quote large blocks.

Typical Uses In This Repo

• Angular 20 control flow and signals interop APIs.
• NgRx Signals (signalStore, withState, withMethods, rxMethod, tapResponse).
• AngularFire / Firebase modular APIs.
• Playwright test APIs.

Prompt Templates

• “Look up the correct API/signature for in (target versions: Angular ~20, @ngrx/signals ~20). Provide minimal usage example.”
• “Confirm best practice for converting Observable to Signal in Angular 20, including cleanup semantics.”

Output Requirements

• Provide the minimal snippet needed to implement correctly.
• Call out version assumptions explicitly (match package.json versions).
