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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and closed-world scope, so the safety profile is covered. The description adds real behavioral context beyond that: the view is blinded to parties, and the caller's own vote becomes visible only once cast. It does not disclose error behavior for unauthorized access (e.g. non-panelist) or pagination/return shape, leaving the disclosure useful but partial.

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?

Two short clauses, scoping context front-loaded after the 'Member panel:' prefix, with no filler. The phrasing is dense to the point of being slightly cryptic ('with your own vote once cast'), which costs a point but nothing is wasted.

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 one-parameter read tool with no output schema, the description conveys the key caller-facing facts: what is returned in principle (the case, with parties hidden), what of your own data is visible, and who may call it. A brief note on what happens when access is denied would make it complete.

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?

With a single required parameter at 100% schema description coverage, the schema already documents case_id as a UUID. The description only refers to it obliquely as 'one case' and adds no format, sourcing, or scoping detail, so it meets the baseline without adding meaning.

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 names a specific operation and resource: read a single panel case, with the distinguishing twist that the content is blinded to party identities. It is clearly a single-case read rather than the sibling list tool panel_list_open or the mutation panel_vote. It stops short of a fully explicit verb+scope phrasing, being somewhat telegraphic, but the resource and access mode are unambiguous.

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?

It states the eligibility conditions for calling it: a member who may sit on the case while it is open, and panelists after it closes. That is genuine when-to-use context rather than implied guidance. It does not explicitly name alternatives such as using panel_list_open to discover a case_id first, so it falls short of a 5.

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