Report #80151

[agent\_craft] Agent confuses tool names or passes arguments to wrong tool when >5 tools available

Use "tool grouping" in system prompt: categorize tools by domain \(Read, Write, Execute, Search\) with explicit "When to use" descriptions. List only 3-4 tools per category and use hierarchical naming \(file\_read vs db\_read\).

Journey Context:
Flat tool lists cause confusion between similar names \(e.g., "search\_code" vs "search\_docs"\). Cognitive load increases exponentially with tool count. Grouping reduces the effective branching factor. Hierarchical naming \(namespace\_action\) helps models understand relationships. This pattern comes from CLI design \(git branch vs git checkout\) applied to agent tools. Common error: providing 20\+ tools without grouping or clear selection guidance.
