set_clip_signature

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

Annotations provide only destructiveHint: false. Description adds that it modifies a clip's time signature, but lacks details on side effects, required permissions, or impact on playback. Does not contradict annotations.

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?

Single sentence with clear purpose and no extraneous words. Front-loaded with the action and resource.

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?

Despite having an output schema (context indicates true), the description omits critical details: parameter ranges, what 'clip's own time signature' means operationally, and how it interacts with existing clip settings. Insufficient for correct invocation in a DAW environment.

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?

All four parameters (numerator, denominator, clip_index, track_index) lack descriptions in the schema (0% coverage). The description does not explain any parameter meanings or constraints, leaving the agent to guess time signature conventions and indexing.

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?

Description clearly states the verb 'Set' and the resource 'a clip's own time signature', with parenthetical context '(polymeter / odd-bar loops)'. This distinguishes it from the sibling tool 'set_time_signature' which likely sets the global signature.

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 explicit when-to-use or when-not-to-use guidance, nor alternatives mentioned. The parenthetical hint implies it's for polymeter/odd-bar loops, but the agent must infer usage context without direct comparison to related tools.

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