v1.2.0Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must carry the burden of behavioral disclosure. It only states that a track is added, without explaining any side effects, whether the operation is undoable, what happens with existing tracks, or what success/failure looks like.
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 a single, front-loaded sentence that states the essential action and resource. Every word earns its place, with no filler or redundancy.
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 mutation tool with no annotations and no output schema, the description is too thin. It fails to mention the meaning of an omitted position, whether the tool returns anything, or potential error conditions. The schema covers parameters but not operational context.
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?
The schema covers all parameters with descriptions, so the baseline is 3. The description adds 'video or audio' which aligns with the trackType enum but adds no new meaning beyond the schema. Position semantics are left to the schema's enum and description.
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 ('Adds a new video or audio track') and the target resource ('to the sequence'), making the tool's basic purpose unambiguous. However, it does not explicitly differentiate from the sibling tool 'add_tracks' beyond the singular/plural name difference.
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 provides no guidance on when to use this tool versus alternatives such as 'add_tracks', 'delete_track', or 'rename_track'. There is no mention of prerequisites, default behavior when 'position' is omitted, or any exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
