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

Annotations already declare this is a non-destructive, non-open-world write, so the bar is lower, and the description adds a genuine authorization detail the annotations do not carry: team-scoped creation requires an admin. It does not mention duplicate-name behavior or what happens when the phrase limit is hit, which keeps it from a 5.

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?

Two compact sentences, front-loaded with the verb and resource definition, followed by the one scoping/authorization caveat. No filler and nothing redundant beyond a minor overlap with the schema default.

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?

With four parameters and no output schema, an agent still lacks any hint of what creation returns (a tracker id? the created object?) or how to proceed afterward. The core call is understandable, but the definition stops short of covering the post-call workflow.

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 75%, with the enum, phrase-mode semantics, and teamId fallback already documented in the schema. The description's "personal by default" largely restates the schema's "Default personal" note, and it says nothing about teamId or the phrases array; the admin note is the only real semantic addition.

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 pairs a specific verb ("Creates") with a specific resource ("topic tracker") and even defines the concept: "a named set of phrases note1 watches for across meetings." That makes it distinguishable from the list/update/delete tracker siblings by verb alone, though it never explicitly names those 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?

It states the default scope (personal) and a prerequisite for the team variant (requires an admin), which is useful selection context. However, there is no explicit guidance on when to create versus update an existing tracker, or when a personal tracker is preferable to a team one beyond the admin constraint.

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