name: external-docs description: Verify external libraries, APIs, and frameworks against current documentation before writing code. Use when about to implement features using external dependencies, when writing import statements for third-party libraries, when unsure if a pattern or method is current, or when the user mentions grounding or verification.

External Docs

Verify external dependencies against current documentation before implementation.

When to Ground

Default: When uncertain, ground.

Decision Tree

CopyWhere does truth live?

CODEBASE ────► Warp-Grep
              "How does X work in our code?"

WEB ─────────► Exa
              "What's the current API for X?"

HISTORY ─────► cm context → cass search
              "How did we do this before?"

TASKS ───────► bv --robot-*
              "What should I work on?"

Exa Query Patterns

Template:

Copy{library} {feature} {version} 2024 2025

Good queries:

CopyFastAPI Pydantic v2 model_validator 2024 2025
Next.js 14 app router server components
React useOptimistic hook 2024

Tools:

• web_search_exa(query) — Documentation search
• get_code_context_exa(query) — Code examples from GitHub
• crawling(url) — Specific doc page

---

Verification

After grounding, check:

---

Record in Bead

Add grounding status table:

Copy## Grounding Status
| Pattern | Query | Source | Status |
|---------|-------|--------|--------|
| `@model_validator` | "Pydantic v2 2024" | docs.pydantic.dev | ✅ Verified |
| `useOptimistic` | "React 19 2024" | react.dev | ✅ Verified |

Status: ✅ Verified | ⚠️ Changed | ❌ Deprecated | ❓ Unverified
