Loading ToolBench
14 tools with basic verb-noun naming (get_, play_, create_, list_, set_, stop_, add_). Descriptions present but generic (avg ~60 chars, well below 194-char baseline). Input schemas visible with types but parameter descriptions are minimal or missing context. No output schemas documented. Error handling returns generic Result<String, String> with no recovery guidance. Missing idempotency hints, rate-limit guidance, and dependency documentation. Composition is reasonable (single responsibility per tool) but lacks chaining metadata.
Add an effect to the current sound
Create a drum loop with the specified pattern
Create a custom effect chain
Create a loop with the specified code
Create a melody loop with the specified notes
Get samples in a specific category
Get the current state of Sonic Pi
No output schemas documented. Tools return Result<String, String> with unstructured text responses. LLMs cannot parse structured data or chain results to downstream tools.
Parameter descriptions are minimal or absent. E.g., 'synth' param in play_note has description 'The synthesizer to use (e.g., "saw", "piano")' but no enum constraint, valid range, or guidance on what happens if invalid synth is passed.

Stop all sounds
No error recovery guidance. Tools return generic error strings with no actionable next steps. E.g., 'Error sending state query' tells LLM nothing about retry eligibility or alternatives.
Tool descriptions are too short (avg ~50 chars vs 194-char baseline). Missing WHEN to use, prerequisites, and side effects. E.g., 'Stop all sounds' lacks context on whether this is idempotent or what state it leaves.
No pagination or result limits documented. list_effects and list_sample_categories return unstructured strings with no indication of max items, offset, or total count.
