[Bug]: Librarian agent uses incorrect tool name 'websearch_exa_web_search_exa' instead of 'websearch_web_search_exa'

[cyrilkong]

Bug Description

The librarian agent's system prompt contains incorrect example function names for the Exa web search tool, causing the agent to call a non-existent tool web_search_exa instead of the correct websearch_web_search_exa.

Error Observed

When librarian agent attempts to use web search:

invalid [tool=web_search_exa, error=Model tried to call unavailable tool 'web_search_exa'. Available tools: ... websearch_web_search_exa, ...]
Tool execution aborted

Root Cause

Location: dist/index.js lines 69282 and 69285

Current (incorrect):

- **Find Docs URL**: Use websearch_exa — `websearch_exa_web_search_exa("library official documentation")`
- **Latest Info**: Use websearch_exa — `websearch_exa_web_search_exa("query ${new Date().getFullYear()}")`

Should be:

- **Find Docs URL**: Use websearch_exa — `websearch_web_search_exa("library official documentation")`
- **Latest Info**: Use websearch_exa — `websearch_web_search_exa("query ${new Date().getFullYear()}")`

The librarian agent reads these example function calls from its system prompt and copies the incorrect tool name.

Verification

Confirmed correct tool name in codebase:

• Line 75594: MCP configuration correctly references the tool
• Line 39032, 49859: Tool whitelist uses websearch_web_search_exa
• Hook exclude list uses websearch_web_search_exa

Impact

• Librarian agent cannot use web search functionality
• Requires manual correction via session continuation
• Affects all installations using oh-my-opencode 3.10.0

Environment

• oh-my-opencode version: 3.10.0
• Installation: mise (npm-oh-my-opencode)
• Platform: macOS Sonoma 14.8.4

Expected Behavior

Librarian agent should successfully call websearch_web_search_exa(query) for web searches.

Suggested Fix

Update librarian agent's system prompt (source file before compilation) to use correct tool name:

• Change: websearch_exa_web_search_exa
• To: websearch_web_search_exa

Lines 69282 and 69285 in compiled dist/index.js.

Correct tool name: websearch_web_search_exa (verified in codebase: hooks/json-error-recovery, hooks/agent-usage-reminder, cli/run/tool-input-preview)

Impact: Librarian agent attempts to call non-existent tool when performing web searches for documentation discovery.
