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

No annotations are provided, so the description carries the full behavioral burden. 'Compare' implies a read-only operation, but the description does not confirm that, nor does it describe permissions, cost, rate limits, or the shape of the comparison it produces.

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?

A single compact sentence with the comparison action and the ranking criterion front-loaded; nothing is wasted, though the brevity comes at the cost of detail rather than being efficient.

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?

An output schema exists so return values need not be explained, but the definition still omits how 'paths' should be formatted and offers no guidance on when to invoke the tool, leaving an agent with too little to call it confidently.

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% for the single 'paths' parameter, and the description never names or explains it. Only the phrase 'several candidates from different registries' loosely implies that multiple paths are supplied, but format, separator, and count are left entirely unspecified.

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+resource (compare several candidates from different registries) plus an ordering behavior (rank by verdict and evidence base), which lets an agent distinguish it from the lint_rules/lint_skill siblings. However, 'candidates' is loosely worded given the tool is compare_skills, so the resource is slightly ambiguous.

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 explicit when-to-use, when-not-to-use, or alternative guidance. The phrase 'from different registries' hints at a cross-registry comparison scenario but never states when an agent should pick this tool over the lint siblings.

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