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

The description adds real information beyond annotations: that clips are split as a side effect and that ripple=true (a default not declared in the schema) closes the resulting gaps. It does not address reversibility, whether locked tracks are protected, or permission requirements - notable because destructiveHint=false is arguably optimistic for an operation that removes timeline content, though editing tools are typically undoable.

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?

Two tightly packed sentences with the primary action front-loaded and the ripple consequence immediately after. No filler; the only shortfall is that density comes at the cost of omitting the range format.

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?

For a four-parameter, nested, content-removing tool with no output schema, the definition covers the core action and one default but leaves open what is returned, what happens to locked tracks, and how multiple ranges are applied. Adequate to invoke, incomplete to invoke confidently.

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 50%: trackIds and projectId are documented in the schema, while ranges and ripple are not. The description partly compensates by declaring ripple's default of true and clarifying that the track scope defaults to all tracks, but it never explains the units or semantics of the start/end pairs inside ranges.

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?

States a precise verb and resource - 'Cut timeline time ranges out of all (or given) tracks' - and adds the important consequence 'splitting clips', which separates it in spirit from delete_clips (whole clips) and keep_ranges (inverse operation). It stops short of naming those siblings explicitly, so an agent still has to infer the boundary.

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 choose this over delete_clips, trim_clip, close_gaps or keep_ranges, all of which appear in the sibling list and overlap conceptually. The only decision-support offered is the ripple default, which is behavioral rather than a when-to-use rule.

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