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

With no annotations, the description carries the behavioral disclosure burden. It mentions the output format ('MIDI file') and input constraints, but does not disclose side effects (e.g., file creation/storage), error behavior, or any required authentication/compute limitations. It is not misleading, but it leaves notable behavioral gaps.

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

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

The description is a single focused sentence, front-loaded with the key verb and output, and contains no redundant or filler language. Every word contributes to the understanding of the tool.

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

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

Given the presence of an output schema and the simple zero-parameter input, the description covers the primary scenario well. It could additionally mention supported audio formats or the exact meaning of 'MuScriptor', but these are not critical gaps for basic invocation.

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

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

There are no structured parameters in the input schema, so the baseline is 4. The description adds essential semantic context by explaining what the tool operates on (a local or public HTTPS audio file), which is not represented in the empty schema.

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

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

The description uses a specific verb ('Transcribe') and clearly identifies the resource ('audio file') and output ('multi-instrument MIDI file'), making the tool's purpose unambiguous. It also naturally distinguishes itself from the sibling tool 'check_model', which is unrelated.

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

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

It establishes clear usage context by specifying accepted input types ('local or public HTTPS audio file') and the intended transformation. While it doesn't explicitly state when not to use it or mention alternatives, the context is sufficiently clear for an agent to decide when to invoke it.

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