compare_mix_to_style

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

readOnlyHint=true already establishes this is a safe read. The description adds genuinely useful context beyond the annotation: it distinguishes dimensions that receive objective 'verdicts' (loudness, true peak, dynamics, low-end mono) from those merely 'reported to judge by ear' (low end, tone). It does not disclose the return shape or what a verdict looks like, but the verdict/by-ear split is real added value.

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?

A single dense sentence front-loads the core action and uses a colon/semicolon to partition the metrics cleanly. No wasted words, though the verdict/by-ear split compresses a lot into one clause.

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?

With no output schema, the description carries the burden of explaining results; it partially does so via verdicts vs by-ear reporting, but leaves the format of a 'verdict' and the origin of style profiles unspecified. Adequate but with visible gaps for a comparison tool.

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 description coverage is 75%, so the schema largely documents track, start_bar, and end_bar. The description mentions the 'style profile' but never says where style values come from or how they relate to siblings like list_genres/get_genre_profile. Baseline 3 is appropriate.

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 pair (measures the mix, compares it against a style profile) and enumerates the dimensions analyzed. The agent can tell what the tool produces, though it does not distinguish this from siblings like analyze_audio, measure_tracks, or master_to_target.

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?

No when-to-use guidance and no alternatives named. Given the cluster of analysis/comparison siblings (analyze_audio, measure_tracks, master_to_target), an explicit routing cue would be expected but is absent; usage is only implied by the description of what gets measured.

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