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

With no annotations, the description carries the full behavioral burden and does disclose meaningful traits: no credential required, free of cost, and the constitutional source. It does not cover ordering, pagination, or freshness of the fingerprint data, but the auth/cost disclosure is real value beyond structured fields.

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?

The return contents are front-loaded in the first two sentences, with credential/cost/source metadata trailing as a compact block. The opening 'I want to see...' phrasing is a stylistic detour from an imperative verb, 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 zero-parameter listing tool with no output schema and no annotations, the description supplies enough: what is listed, the fields included, and the access/cost profile. It lacks a note on result ordering or scope of 'where available' fingerprints, which keeps it below 5.

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 (schema coverage 100% trivially), so the baseline is 4. There are no parameter semantics to clarify and the description correctly does not invent any.

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 resource set (laws, rules and procedure instructions published by the Court) and enumerates what is returned: documents, versions, published status, links, and digital fingerprints. The plural 'Lists the documents' implicitly separates it from the sibling read_instrument, but no sibling is named explicitly, so it stops short of a 5.

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?

Usage is framed as a user intent ('I want to see which laws...'), which implies the discovery/browse case, but there is no explicit when-to-use statement, no exclusions, and no routing to read_instrument for retrieving a single document. Adequate but leaves the agent to infer the choice.

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