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

With no annotations, the description carries the full disclosure burden. It usefully declares 'Credential: none' and 'Cost: Free', which tells the agent no auth or payment is required, and the verb 'collects' implies a read operation. However, it never confirms read-only status, reversibility, or what the response contains.

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 short sentences, front-loaded with purpose and followed by operational metadata (credential, cost, rule source). Nothing is wasted, though the quoted first-person intent phrasing is slightly indirect compared to a direct verb-first statement.

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 informational tool with no output schema and no annotations, the description covers purpose and access metadata but omits the return format and any differentiation from closely named siblings such as restatement_index. An agent can invoke it, but selection confidence is incomplete.

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, so the schema needs no documenting and the description cannot add parameter meaning. Baseline 4 applies for a parameterless tool.

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 concrete outcome: rules from published decisions organised by topic, each linked to its source, with binding rules identified. That is specific enough for an agent to know what the tool produces. It does not, however, distinguish itself from the obvious sibling restatement_index, which is named nowhere in the text.

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 when-to-use or when-not-to-use guidance is given, and no alternative tool (e.g. restatement_index, law_index, lookup_authority) is referenced. The opening 'I want the Court's case law organised by topic' implies an intent but gives no selection criteria against siblings.

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