Context7 Integration

When to Use

Use Context7 MCP to fetch up-to-date framework documentation in three contexts:

1. During research (plan-phase Step 2): fetch relevant framework docs per task to populate research notes
2. During implementation (execute-phase): look up specific API details when building features
3. During review/fixing: verify patterns match the current framework version before flagging issues

How to Use

Two-step process for every lookup:

1. Resolve the library ID: Call mcp__context7__resolve-library-id with the library name (e.g., laravel/framework). This returns the correct Context7 identifier.
2. Query the docs: Call mcp__context7__query-docs with the resolved ID and a specific query string.

Rules:

• Always use specific queries: "Inertia useForm validation display" -- not "Inertia docs"
• One concept per query. Do not combine unrelated lookups.
• Do not re-fetch the same documentation multiple times in one session. Cache results mentally and reuse them.

Library IDs Per Stack

Stack	Libraries to Query
laravel-inertia-vue	laravel/framework, inertiajs/inertia, vuejs/core
laravel-inertia-react	laravel/framework, inertiajs/inertia, facebook/react
react	facebook/react
nextjs	vercel/next.js
nestjs	nestjs/nest
react-native-expo	facebook/react-native, expo/expo

Read config.json to determine the project stack, then query only the relevant libraries from this table.

Graceful Fallback

Context7 enhances research but is never required. Follow this three-tier check:

1. Check config: Read config.json for the "context7" field. If false, skip Context7 entirely.
2. Attempt the call: If enabled, call the MCP tools. If the tools are not available (error, not configured), fall back to codebase analysis.
3. Log and proceed: When falling back, note "Context7 not available, using codebase patterns only" and continue. Never hard-fail because Context7 is unavailable.

Query Strategies

Keep queries focused and practical:

• Component patterns: Query component API and composition patterns (e.g., "Vue defineModel two-way binding")
• API details: Query function signatures and configuration options (e.g., "Laravel FormRequest authorize method")
• Testing: Query testing utilities and patterns (e.g., "Pest assertInertia page component")
• Configuration: Query setup and configuration options (e.g., "Inertia shared data middleware")
• Migrations/models: Query schema and relationship patterns (e.g., "Laravel belongsToMany pivot table")

Prefer specific framework features over general queries. A targeted query returns more useful context than a broad one.

If a query returns no useful results, refine it with more specific terms rather than broadening it.
