analyze_audio_character

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

The annotation readOnlyHint indicates no mutation, but the description adds that it renders to WAV and computes metrics, mentioning optional dependency for higher accuracy. This provides some behavioral context, but it does not clarify if the WAV is saved or temporary, nor does it discuss performance or resource implications.

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 very concise with two sentences, packed with essential information: the action, the computed metrics, and the optional enhancement. Every phrase serves a purpose, making it easy to process quickly.

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 that there is an output schema (not shown but known to exist) and no required parameters, the description adequately covers what the tool does and what it returns. It lacks details on prerequisites (e.g., whether stems/master must be audible or selected) but is mostly complete for its simplicity.

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?

There are no parameters, so the schema coverage is complete (100%). The description adds value beyond the schema by explaining what the tool computes and the optional extra, which helps the agent understand the tool's capabilities without needing to interpret an empty 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?

The description specifies the action ('Render stems/master to WAV and compute') and lists exact metrics computed (3-band energy, spectral centroid, LUFS, etc.), making the tool's purpose very clear and distinguishing it from sibling analysis tools like analyze_groove or analyze_harmony.

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 implies usage for obtaining post-FX sonic fingerprint metrics, but does not explicitly state when to use this tool versus alternatives (e.g., analyze_groove) or provide any exclusion criteria. The sibling names provide some context, but the description lacks direct guidance.

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