[synthesis] Agent selects slightly wrong tool but execution succeeds, causing silent data corruption downstream

Calculate and monitor the cosine similarity between tool descriptions in your function registry. If any two tools exceed a 0.85 similarity threshold, merge them or differentiate their descriptions explicitly. Add a pre-execution validation step that compares the selected tool's parameters against the user's initial intent.

Journey Context:
As agent toolkits grow, tool descriptions overlap in embedding space. The agent routes to search\_user\_files instead of search\_system\_files. Both return a 200 OK with an array of files. The orchestration layer sees a successful tool call. The failure only manifests steps later when the agent tries to modify a system file it doesn't have permissions for, or worse, modifies the wrong file silently. Monitoring tool success rates hides this; you must monitor tool selection confidence and embedding distance between available tools.
