🎯 Use case
This file lives under “hooks/”, which covers reusable UI or integration hooks. On the API surface it exposes useMergedTools — mainly functions, hooks, or classes. Dependencies touch React UI. It composes internal code from Tool, tools, state, and utils (relative imports).
Generated from folder role, exports, dependency roots, and inline comments — not hand-reviewed for every path.

/**
* React hook that assembles the full tool pool for the REPL.
*
* Uses assembleToolPool() (the shared pure function used by both REPL and runAgent)
* to combine built-in tools with MCP tools, applying deny rules and deduplication.
* Any extra initialTools are merged on top.
*
* @param initialTools - Extra tools to include (built-in + startup MCP from props).
* These are merged with the assembled pool and take precedence in deduplication.
* @param mcpTools - MCP tools discovered dynamically (from mcp state)
* @param toolPermissionContext - Permission context for filtering
