Behavior2/5

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

No annotations are provided, and the description does not disclose behavioral traits such as whether the operation is read-only, any side effects, permissions needed, or response details. It only describes the basic action without further transparency.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is very concise: two sentences plus an Args section, front-loaded with the main purpose. Every piece of information earns its place with no redundancy.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's simplicity, the description is mostly complete: it states the purpose, param details, and a helpful note. However, lacking annotations, it could explicitly mention that the operation is read-only and safe to call.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The description adds value beyond the input schema by specifying the format of tracker_id ('TRK...' id) and the auto-resolution behavior of account_id, which are not present in the schema (0% description coverage).

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description 'Get full detail for a specific tracker' clearly states the action (get) and resource (tracker), with specificity (full detail). It distinguishes from sibling tools like 'list_trackers' and 'update_tracker'.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description hints at usage with 'Args: tracker_id: 'TRK...' id.' and 'account_id: Auto-resolves if omitted.', but does not explicitly state when to use this tool versus alternatives (e.g., list_trackers) or provide exclusion criteria.

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