humanize_clip_timing

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

No annotations provided, so the description must fully disclose behavior. It states that timing variation is added, but does not mention whether the modification is destructive, reversible, or if it affects playback in any specific way. Missing details like 'modifies clip in place' or 'does not affect existing automation'.

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 brief and to the point, with a concise sentence followed by a bulleted list of parameters. Each part serves a purpose, though the bulleted list partially duplicates schema information but adds value with examples.

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 no output schema and no annotations, the description should provide more context about what the tool does to the clip (e.g., permanent change, undoable) and what the result looks like. It does not mention return values or side effects.

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 text provides clear explanations for each parameter, including example values for 'amount' (0.05, 0.1, 0.2). This adds significant meaning beyond the raw schema definitions.

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 action (add random timing variation) and the target (notes in a clip), distinguishing it from the sibling tool humanize_clip_velocity which modifies velocity. However, it does not explicitly name the sibling or contrast them.

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 guidance on when to use this tool versus alternatives like humanize_clip_velocity or other clip editing tools. The description only explains what the tool does, not when it should be chosen.

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