select_track

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

With no annotations, the description carries the full burden of behavioral disclosure, but it only says 'Navigate into' without explaining side effects, state changes, or failure conditions. It does not indicate whether this action changes the current page, requires a prior list of tracks, or throws errors for invalid input.

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 with no redundant wording. It is appropriately concise for a simple operation, though it sacrifices important contextual details that could be added without significant verbosity.

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 exists in a browser-automation suite with siblings like list_tracks and navigate, yet the description provides no context about dependencies or expected flow. It does not mention that tracks must be listed first, how navigation is realized, or what the resulting state is, making it incomplete for an agent to invoke reliably.

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 provides a complete description of the parameter 'trackNameOrId' (partial match or index number), achieving 100% schema coverage. The tool description adds no extra parameter semantics, so the baseline score of 3 applies.

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 'Navigate into a specific track' clearly identifies the action (navigate) and the target resource (track), which is specific enough to distinguish from sibling tools like select_course. However, it does not explicitly contrast with any sibling or mention alternatives, so it falls short of a 5.

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 such as list_tracks or select_course. It does not mention prerequisites (e.g., browser launched, login required) or typical usage sequences, leaving the agent without context for selection.

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