[gotcha] Agent reasoning loops or exceeds max steps when forced to chain highly granular MCP tools

Design coarse-grained composite tools for common multi-step workflows \(e.g., find\_and\_replace instead of read\_file -> edit\_file -> write\_file\). Limit the depth of tool dependencies.

Journey Context:
To keep tools pure, developers create highly granular tools \(e.g., open, read, modify, save\). An LLM attempting a simple find-and-replace must reason through 4-5 sequential tool calls. This increases latency, consumes context tokens with intermediate outputs, and drastically increases the chance of hitting the agent's maximum step limit or entering a reasoning loop if an intermediate step fails. Composite tools reduce the reasoning burden.
