garageband_make_from_tab

Convert guitar tab notation from text, file, image, or URL into MIDI and open it in GarageBand. Supports BPM override, tuning, arrangement, and export to audio formats.

Instructions

High-level recipe: accept tab text/file/image/URL, create MIDI, open it in GarageBand, optionally show panels, set master volume, snapshot, screenshot, and export audio.

Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations provided, so description carries full burden. It mentions high-level steps but lacks details on side effects, destructive actions, permissions, or what happens to existing projects. The one-sentence summary is insufficient for a tool with 28 parameters.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Single sentence of 27 words is concise and front-loaded with 'High-level recipe'. However, it reads as a list and could benefit from structured formatting.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness1/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given 28 parameters, no output schema, and many sibling tools, the description lacks necessary context. It does not explain workflow steps like how to use 'tab_text' vs 'tab_file', or what 'snapshot' means.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters1/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is only 7%, yet the description does not describe any parameter meanings. It only lists actions without mapping to specific parameters, failing to compensate for the lack of schema descriptions.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Description clearly states it's a recipe that accepts tab text/file/image/URL, creates MIDI, opens in GarageBand, optionally shows panels, sets master volume, snapshots, screenshots, and exports audio. This specific verb+resource combination distinguishes it from sibling tools like garageband_tab_to_midi or garageband_image_to_midi.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool vs alternatives like garageband_tab_to_midi or garageband_make_from_score. Does not specify context or exclusions.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
