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

Annotations indicate readOnlyHint: true, and the description is fully consistent, describing the tool as 'Measures the dynamic character' (read operation). The description goes beyond annotations by explaining each metric's meaning (e.g., crest_factor_db, transient_density) and providing contextual semantics (e.g., 'high crest_factor = very dynamic'). This rich behavioral detail aids the agent in understanding what the tool does and how to interpret outputs.

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 well-structured: a summary line, a list of metrics with explanations, compression guidance, argument description, and a return statement. It is front-loaded with the core purpose. While informative, it could be slightly more concise by reducing redundant phrasing (e.g., 'Measures the dynamic character of a track' could be merged with the first line). Every sentence earns its place, but the length is appropriate for the detail provided.

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 tool has an output schema (context signal), the description adequately covers the main return values (dynamics descriptors, 10-segment RMS contour, compression suggestions) and their meanings. However, it lacks information about file format constraints (e.g., sample rate, bit depth) or performance considerations. Overall, it is sufficiently complete for an agent to use the tool 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 single filename parameter has 0% schema description coverage. The description compensates fully by explaining how to specify the file: 'Name of the WAV file in the exports directory (without path), or absolute path to any WAV file.' This adds essential context not present in the schema, making the parameter's usage unambiguous.

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 clearly states the tool's purpose as 'Dynamics analysis' and lists specific metrics (crest factor, loudness range, etc.). It distinguishes itself from sibling analysis tools (e.g., analyze_harmonic_rhythm, analyze_spectrum) by focusing on dynamic character. The verb 'analyze' paired with 'dynamics' makes the action and resource explicit.

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 provides guidance on interpreting results for compression decisions, which helps the agent decide if dynamics analysis is needed. However, it does not explicitly state when to use this tool over other analysis tools or when not to use it. There are no exclusions or alternatives mentioned, leaving the agent to infer intent.

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