Module tools 

Tools layer. The tool registry (Tool trait, Registry, ToolResult, ToolCtx) and most tool implementations (fs, edit, search, web, browser, git, exec, todo, media, code-nav, the memory tool…) live in the sparrow-tools crate so the heavy tool code compiles once and is cached. Re-exported here so existing crate::tools::* imports keep working.

extras and subagent stay in the binary crate: they sit at the top of the dependency graph (they hold an Arc<Engine>, spawn sub-agents via the Engine/Router, and carry gateway::GatewayResponse), which would create cycles if pulled below the engine.

Modules

browser_sandbox

builder_tools

code_exec

Code execution in sandbox — runs code with timeout.

code_nav

Code navigation tools that bring Sparrow’s self-coding loop closer to a frontier agent’s: glob (find files by name pattern) and symbols (find where a symbol is defined / who calls it). The symbols tool is a regex-based index today; a tree-sitter AST upgrade keeps the same name/schema.
