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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint, and destructiveHint=false, so the safety profile is covered. Because there is no output schema, the description carries the burden of describing the return value, and it does so well by enumerating the returned fields. It adds no operational context such as auth requirements, rate limits, or what an empty/inactive committee response looks like.

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 front-loaded sentence that names the resource first, then lists the returned data. It is dense but every clause conveys a distinct returned field, so little is wasted; a light structural split into purpose vs. return contents would improve scannability.

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 zero-parameter read operation with no output schema, the description supplies enough field-level detail that an agent knows what it will receive and can decide whether calling it is worthwhile. Only minor gaps remain, such as how member statuses are represented or how absent actions are reported.

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 takes zero parameters and the schema coverage is 100%, so there is nothing for the description to disambiguate; the baseline for a no-param tool is 4.

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?

Names a specific resource (the Cardano constitutional committee) and enumerates exactly what the response covers: members with status and term-end epoch, voting-member count, quorum, minimum size, constitution in force, and the latest committee/no-confidence/constitution actions. It is clearly distinct from list_governance_actions or get_drep in content, though it does not explicitly contrast itself with them.

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 statement of when to call this versus alternatives, nor any prerequisites or context. The closest sibling, list_governance_actions, is never mentioned even though the description overlaps with it by promising 'the latest committee, no-confidence and constitution actions'. Usage must be inferred entirely from the content list.

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