unlock_tracker_stats

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

No annotations are provided, so the description carries full responsibility. 'Get' implies a read-only operation, but it does not disclose what exactly the statistics include, whether any side effects occur, or the format of the summary. For a tool named 'tracker_stats', more behavioral detail would be expected.

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 of six words, with no fluff or redundancy. It efficiently communicates the core purpose without wasting tokens.

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 parameterless tool with no output schema, the description is minimally viable but lacks specificity about what 'tracker statistics' includes or how this summary relates to other unlock tools. It could be clearer about the scope (e.g., across all projects, vesting schedules) to help an agent understand its value, but it is not misleadingly 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?

The tool has zero parameters, so schema coverage is trivially 100%. Per the rubric, a baseline of 4 is appropriate for parameterless tools, and the description doesn't need to add parameter details. It provides no contradictory or confusing parameter info.

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 a read operation ('Get') targeting 'overall tracker statistics and summary', which distinguishes it from more specific unlock tools like unlock_get_upcoming or unlock_get_calendar. However, it lacks explicit differentiation from sibling tools that might also provide aggregated data, so it's not 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?

There is no guidance on when to use this tool versus alternatives, nor any exclusions. The description is a bare statement with no context about its typical use case or relationship to other unlock tools.

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