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

With no annotations, the description carries the behavioral burden, and it does describe the musical behavior (downbeat/offbeat patterns per tune type) and return value ('Returns notes created, tune type info, meter, and pattern breakdown'). However, it does not state operational side effects such as whether the tool appends to or replaces existing notes on the specified track, or what happens with invalid inputs.

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 long, but the length is largely devoted to necessary tune-type distinctions and parameter semantics, structured under clear headings. The opening sentence immediately states purpose, and each bullet for tune types adds selection-relevant information rather than filler.

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 9 parameters, no annotations, and an output schema present, this description is unusually complete: it covers all parameters, explains the style and all tune-type variants, and states the return payload. It could mention prerequisites about the target track, but overall it gives an agent enough to invoke correctly.

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?

The 'Args' block provides a semantic description for every parameter, including ranges ('bars: Number of bars (4-32, even)'), value ranges ('velocity: Base velocity 0-1'), and default MIDI pitches. The schema itself has zero descriptions, so this completely compensates for the 0% schema coverage, especially the detailed tune_type guidance.

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 opens with 'Create an Irish traditional music accompaniment — bodhrán + feet for session tunes,' which is a specific verb+resource that clearly distinguishes this from sibling creation tools like create_reggae_percussion or create_tala. It further enumerates six tune types, reinforcing the focused scope.

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?

The description explains that Irish trad is defined by tune types and that the accompaniment is minimal and supportive, providing clear contextual when-to-use guidance. However, it does not explicitly name alternative tools or state when not to use this tool, though the context is sufficient for selection.

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