track_changes

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

With no annotations, the description must disclose behavior, but it only says 'monitor' with no details on side effects, return format, or performance implications. It does not explain whether this is a read-only operation, what data it returns, or how changes are tracked, which is a significant gap for a monitoring tool.

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 sentence with no filler words or redundant information. It is front-loaded and appropriately sized for a one-line description, though the brevity comes at the cost of detail.

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 has 3 parameters (one required, one with enums) and no output schema or annotations. The description fails to explain what the tool returns, how the optional parameters affect results, or any practical usage context. This is completely inadequate for a tool that could involve querying historical changes.

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 100%, so each parameter already has a description. The tool description adds no additional meaning about how these parameters affect behavior, so the baseline score applies without extra credit.

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 states a specific verb ('monitor') and resource ('vault evolution and changes over time'), which conveys the core function. It is distinguishable from sibling tools like scan_vault and generate_report, though it could be more explicit about what kind of output is produced.

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 given on when to use this tool versus alternatives. Sibling tools exist, but the description does not mention any use cases, exclusions, or selection criteria, leaving the agent to infer based solely on the tool name.

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