enable_track

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

With no annotations present, the description carries the full burden of behavioral disclosure. It states the outcome (enable/disable) but does not mention preconditions (e.g., track must exist), side effects, error behavior, or whether changes are reversible. For a mutation tool, this is a significant gap.

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 concise sentence with no filler. It is well-structured for readability, but its brevity comes at the expense of critical contextual information. Since the dimension measures conciseness alone, it earns a high score, but not a 5 because it could be slightly more informative without becoming verbose.

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?

The tool has 3 parameters, no output schema, and no annotations, so the description must provide comprehensive context. It fails to explain parameter semantics, return values, or usage scenarios. For an agent to invoke this tool correctly, significant information is missing, making the description incomplete.

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. It provides no information about the parameters (track_type, track_index, enable), their meanings, or how they relate to the action. The agent is left to infer from parameter names alone, which is insufficient.

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 tool's function: enabling or disabling a track in the current timeline. The verb 'enable' plus the resource 'track' provides specific purpose, and mentioning 'disable' covers the boolean parameter. It implicitly distinguishes from sibling tools like add_track (creation) and set_track_volume (volume), though it does not explicitly name alternatives.

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 is provided on when to use this tool versus alternatives. There is no mention of prerequisites, conditions, or exclusions. The description only states what the tool does, not when it should be invoked.

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