add_track

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

No annotations provided. Description is minimal and does not disclose behavioral traits such as whether count parameter overrides the singular 'a new', or any side effects. There is a slight contradiction between singular 'a new' and the count parameter allowing multiple.

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?

Single sentence, no redundant words. Front-loaded with purpose. However, it omits key information about parameter behavior, so conciseness comes at cost of completeness.

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 simple tool with 2 parameters, no output schema, and no annotations, the description should explain the behavior of count and any default. It does not, leaving the agent uncertain about adding multiple tracks. Incomplete for reliable tool selection.

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 100%, so description need not repeat parameter details. The description adds no additional meaning beyond the schema; it does not clarify the effect of count or the difference between video and audio tracks.

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?

Description states clear verb+resource: 'Add a new video or audio track to the active sequence'. It is specific about the resource type (track) and location (active sequence), but does not differentiate from sibling 'add_tracks' which may have similar functionality.

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 vs alternatives like 'add_tracks' or 'add_adjustment_layer'. No context on prerequisites or scenarios.

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