[synthesis] Agent selects wrong tool due to semantic similarity in tool names

Ensure high 'semantic distance' between tool names and descriptions. Use distinct, specific verbs \(e.g., \`delete\_file\` vs \`clear\_file\_contents\`\) and avoid overlapping descriptions.

Journey Context:
LLMs rely heavily on semantic similarity for tool selection. If tool names are too alike \(e.g., \`search\_user\` vs \`find\_user\`\), the agent will confidently select the wrong one. This isn't a reasoning failure; it's a retrieval failure. Increasing the semantic distance between tools reduces the chance of collision and makes the agent's selection more deterministic.
