humanize_clip_timing

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 discloses the action (random timing variation) and provides example amounts (0.05 subtle, 0.1 moderate, 0.2 heavy), but it does not mention side effects, reversibility, whether it affects all notes, or if it only works on MIDI clips. This is a moderate level of disclosure with clear gaps.

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 compact, with a clear first sentence and a structured 'Parameters:' section. Every sentence is informative, and there is no repetition or fluff. The format is easy to parse and front-loaded.

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's simplicity (3 flat parameters, no output schema), the description covers the core usage well. It explains the purpose and all parameters with examples. However, it omits details like whether the clip must be MIDI or the exact nature of the randomness, but these are minor for the task complexity, so a 4 is appropriate.

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 0%, but the description compensates fully by listing all three parameters and providing meaningful explanations and example values. 'amount: Amount of timing variation in beats (0.05 = subtle, 0.1 = moderate, 0.2 = heavy)' adds value beyond the raw schema, making the parameters self-documenting.

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 uses a specific verb+resource: 'Add random timing variation to notes in a clip' and clearly distinguishes from sibling tools like humanize_clip_velocity (which varies velocity) and quantize_clip (which removes timing variation). The purpose is immediately clear.

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 states the context: 'for a more human feel,' which implies use when you want to add subtle variety to clip timing. It does not explicitly mention alternative tools or exclusions, but the clear purpose and context provide adequate guidance, earning a 4 rather than a 3.

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