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

The description adds useful context beyond the annotations by clarifying that the tool returns the complete official text and a canonical citation URL. Combined with readOnlyHint=true, openWorldHint=false, and destructiveHint=false, the behavioral profile is clear, though it does not discuss auth, rate limits, or error conditions.

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 description is a single front-loaded sentence with no redundant wording. It efficiently communicates the operation, scope, and return content without wasting space.

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 simple one-parameter read-only tool with full schema coverage, annotations, and an output schema, the description is largely complete. The only minor gap is that the search-then-fetch usage sequence is implied through the schema rather than stated in the description.

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?

Schema description coverage is 100%, so the parameter semantics are already well documented by the schema. The description adds only slight reinforcement by specifying that the ID identifies a public document, meriting the baseline score for a schema-heavy definition.

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 verb-resource pair: retrieving the complete official text and canonical citation URL for one public document ID. This clearly distinguishes a single-document fetch from broader search behavior, though it does not explicitly contrast with the sibling search tool.

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 implied by the scope 'for one public document ID' and by the schema note that the ID is returned by the search tool, suggesting a search-then-fetch workflow. However, the description itself does not explicitly state when to use this tool versus search or other siblings, nor does it mention exclusions.

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