remove_segment

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

No annotations are provided, so the description carries the full burden. 'Ripple-delete' usefully implies that subsequent content shifts, but it does not say whether deletion is permanent/undoable, what happens to clips that straddle the boundaries, or whether a project lock is required for a destructive timeline edit.

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?

A single well-formed sentence with the operation and boundaries front-loaded and no filler. Its brevity is close to under-specification rather than verbosity, so it earns a 4 rather than 5.

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?

This is a destructive timeline mutation with no annotations, no output schema, 0% parameter coverage, and three required parameters. The description does not cover consequences, reversibility, or the project scope, which leaves real gaps an agent must guess at.

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%, so the description must compensate for all three parameters. It clarifies that start_s and end_s are timeline positions for the span to be removed, but it never mentions project_name or the unit (seconds) explicitly, leaving the most important scoping parameter undocumented anywhere.

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 ('ripple-delete') and resource ('timeline span between start_s and end_s'), which is more informative than a bare 'remove'. However, it never distinguishes itself from the sibling tools remove_clip and trim_clip, so an agent cannot tell which removal semantics apply without further inference.

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?

There is no indication of when to use this versus remove_clip, trim_clip, or split_clip, and no prerequisites or exclusions are given. The word 'ripple' hints at a behavioral consequence but not at a usage decision.

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