create_track

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

With no annotations, the description carries the full burden. It discloses that the track is appended at the end, but says nothing about what is returned (track index/ID), whether a project must be open first, or what happens on duplicate names.

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?

Two short lines, action front-loaded, zero filler. It is efficient though it trades away detail that would have been useful for an unannotated mutation 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?

For a no-annotation, no-output-schema mutation with an undocumented required parameter, the definition is thin: no prerequisites, no result shape, no failure behavior. The only additions are placement and the track_type vocabulary.

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?

Schema coverage is 0% and the schema declares no enum, so listing "audio, midi, instrument, folder" is genuine added value for track_type. The required `name` parameter is never explained, and the audio default is left to the 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?

States a specific verb and resource ("Create a new track") plus the placement semantics ("at the end of the project"), which separates it from insert_track_template and create_bus. It does not explicitly name a sibling alternative, but the action is unambiguous.

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?

There is no guidance on when to use this versus insert_track_template or create_bus, nor any prerequisite such as a loaded project. The only usage signal is implicit in the append-at-end phrasing.

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