[gotcha] Tool selection failure with semantically overlapping tool names

Ensure tool names and descriptions have distinct, non-overlapping semantic boundaries. Use highly specific verb-noun pairs \(e.g., query\_database vs insert\_database instead of manage\_database\).

Journey Context:
When multiple tools share similar verbs or nouns \(e.g., get\_file, read\_file, fetch\_url\), the LLM's attention mechanism struggles to differentiate them. This leads to reasoning loops where the agent calls the wrong tool, gets an error, and retries with the same wrong tool. Developers assume more tools equal more capability, but semantic overlap actually degrades capability. The fix is strict disambiguation in the name and description fields, even if it feels redundant to a human.
