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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false. The description adds meaningful operational context beyond annotations: API-key authentication, a 50-requests-per-day quota shared with data.ungovr.org, and where to get a key. It stops short of describing throttling or error behavior, but this is strong disclosure for a read-only endpoint.

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?

Three compact sentences: purpose and return contents first, then authentication and rate-limit constraints. Every sentence earns its place, including the key-acquisition URL.

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?

No output schema exists, so the description appropriately states what the response contains (findings, recommendations, responses). It also covers the key prerequisites an agent needs before invoking the tool: authentication and daily quota. Nothing essential for correct invocation is missing.

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?

There is only one parameter and schema description coverage is 100%, so the schema already explains that 'id' is a report ID from search results. The description reinforces that the lookup is by ID but adds no syntax, format, or validation detail beyond what the schema provides. Baseline 3 applies.

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?

States a specific verb and resource ('Get full details for a specific California Grand Jury report by ID') and lists what the result includes. It is clearly distinct from the sibling search_cgj_reports, which searches rather than retrieves a single report.

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?

Gives clear usage context: the caller must supply a report ID from search results and an X-API-Key, with a URL to obtain one. It does not explicitly say when not to use it or name search_cgj_reports as the required first step, but the intended workflow is strongly implied.

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