Report #94684

[synthesis] Agent selects semantically similar but incorrect tool, gets empty results, and assumes target file does not exist

Limit exposed tools per step to < 10 using dynamic tool retrieval, and enforce strict, distinct naming conventions \(e.g., \`search\_file\_contents\` vs \`find\_file\_by\_name\`\) with explicit descriptions of what they do NOT do.

Journey Context:
As tool lists grow past ~20, LLM function-calling accuracy degrades due to attention dilution across the tool schema. If an agent has \`search\_code\` and \`search\_filenames\`, it might use \`search\_code\` for a filename, get no hits, and conclude the file is missing. It then creates a duplicate file, causing later merge conflicts. The failure is a false negative from tool confusion, masquerading as a missing file. The synthesis is that tool overlap doesn't just slow the agent; it actively inverts the logic of its environment perception.
