Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden for behavioral disclosure. It only states the action (arm/disarm) without revealing side effects, prerequisites (e.g., track must exist), or confirmation that the arm parameter sets the exact state (no toggle behavior specified).
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 efficiently conveys the core action. However, it could be slightly improved by adding more context without becoming verbose, but it avoids 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 tool with 3 parameters and no output schema, the description is insufficient. It does not explain how 'track_index' is used (e.g., zero-based indexing) or the behavior of 'arm' when the track is already in that state. The required 'ctx' parameter is not clarified in the tool 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?
Schema description coverage is 0%, yet the description does not elaborate on parameters. 'track_index' (integer) and 'arm' (boolean) are not explained beyond their titles. The description adds no value to the schema, which lacks descriptions, so the agent lacks context for values (e.g., index range, arm meaning).
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 verb 'arm or disarm' and the resource 'a track for recording,' making the tool's purpose unmistakable. It distinguishes from sibling tools like 'set_track_mute' or 'set_track_solo' by specifying recording-specific state.
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 (e.g., checking if track is already armed, required track state). No context or exclusionary criteria are mentioned, leaving the agent to infer usage.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
