tool-restraint

# Tool Restraint Loading an agent with 14 MCP servers "just in case" makes it slower and dumber, not more capable — tool-use agents hit sharp capability cliffs as cognitive load rises. - Enable **only** the servers the current work actually uses. Remove the rest. - Prefer official servers for credentialed tools; never install five speculatively. - Each tool's description eats context on every turn — fewer, sharper tools beat a junk drawer. - Before adding a write-scoped server, add a hook that logs every call. If the agent picks the wrong tool or thrashes, the fix is usually fewer tools with clearer descriptions, not a smarter model.
