Track Model

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

No annotations are provided, so the description carries the full burden. It does disclose that '' clears the value and that the result appears in project_info and render, which is useful. However it says nothing about permissions, side effects on other fields, or whether the recorded model affects rendering behavior.

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?

Compact but written as a dense run-on with unusual phrasing ('Fits record it themselves') that requires re-reading. It front-loads the core purpose reasonably, but the parameter and guidance clauses are tangled together rather than structured.

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?

An output schema exists, so return values need not be explained, and the description notes where the model is shown. It covers the two non-obvious parameters and the clearing behavior, leaving only permissions and side effects unaddressed.

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%, so the description must compensate, and it does well for the two non-obvious fields: 'on' enumerates concrete value forms ('ref', 'ref:<stem>', 'sound:<name>', a path, 'designed', ''), and 'by' is explained as the method. 'track' and 'project' are left implicit but are self-evident from context.

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: 'Record what a track's sound is modeled on', and ties the result to where it surfaces ('shown by project_info and render'). It is genre-specific and jargon-heavy, but a reader can distinguish it from siblings like track_set or instrument_fit.

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 closing sentence hints at when this is unnecessary ('mimic profiles, measured library voices and imported samples need nothing') and names related tools (instrument_fit apply_to_track, track_fit apply=True), but the phrasing is cryptic and gives no explicit 'use X instead when Y' instruction.

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