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

Annotations declare destructiveHint=false and idempotentHint=true, so the description's statement that clips are removed is genuinely useful context that the annotations do not convey. However, it does not explain why a clip-deleting cascade is flagged non-destructive (presumably because every edit returns a new timeline handle and is undoable) or whether the removal is reversible — the single most important thing an agent needs before calling this.

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 short sentences, front-loaded with the action and its blast radius. "(see the server instructions)" is a deferral that forces an extra lookup, which is the only real waste.

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?

An output schema and annotations exist, so return values need not be spelled out. Still missing for a mutation tool: reversibility/undo semantics, the expected track_id format, and whether track_id must belong to the given timeline_id.

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 coverage is 67%; timeline_id and preview are documented in the schema, but track_id has no description anywhere. The description adds nothing about parameters, so it neither compensates for the track_id gap nor explains the preview option's relevance to a removal call (baseline 3 at this coverage level).

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 specific verb and resource ("Remove a track") and adds the important scope detail that its clips go with it, which distinguishes it from clip.remove and clip.link. No explicit sibling routing, but the resource is unambiguous.

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 versus track.set, clip.remove, or timeline-level edits. The agent must infer that this is the whole-track deletion path from the name alone.

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