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

Annotations already declare readOnlyHint=true, openWorldHint=true, and destructiveHint=false, so safety behavior is covered. The description adds that these mirror PDF report sections, which is useful context, but says nothing about auth, rate limits, or what a missing section returns.

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 sentences, front-loaded with the verb and resource; the enum list is long but earns its place by clarifying allowed values. Slight verbosity from enumerating all sections already in the schema.

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?

Output schema exists so return values needn't be described. However, with 0% schema description coverage and only the section list, the description is minimally adequate: it doesn't explain report_id semantics or error behavior for an invalid report/section.

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 coverage is 0%, so the description carries the burden. It enumerates the section enum values (duplicating the schema) but adds no meaning for report_id or the format/meaning of section values. Baseline 3 as schema has an enum that is self-documenting.

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 ('Fetch') and resource ('one of a report's structured sub-resources') and then enumerates every possible section value, making the scope concrete. An agent can pair this with get_report unambiguously.

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?

The 'Mirrors the sections of the PDF report' line implies this is the way to retrieve sub-resources of a report, but no explicit when-to-use vs get_report or alternative is given. Usage is inferable but not spelled out.

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