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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is fully covered and the description does not need to repeat it. The description's one genuine behavioral contribution is 'full text,' implying this returns complete untruncated content rather than a snippet, but it says nothing about what an invalid or unknown ID yields or how large documents are handled.

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?

One sentence, zero filler, with the resource scope front-loaded and the illustrative IDs parenthesized rather than padding out a separate sentence. Nothing could be removed without losing information.

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 single-parameter read-only getter with no output schema and full annotation coverage, the description supplies what an agent needs to call it: what it returns ('full text'), by what key, and valid key shapes. The remaining gap is the lack of any statement about error behavior for bad IDs or the relationship to sibling getters, which matters given four overlapping siblings.

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 100% and the single parameter's own description ('Document ID from search') already explains provenance, so the baseline would be 3. The description earns an extra point by enumerating concrete ID shapes (question-F5, scorecard-finance, overall, methodology), which teaches the agent the ID grammar and origin that the schema never spells out.

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 specific verb and resource — returns the full text of exactly one benchmark document, identified by ID — and the parenthetical examples (question-F5, scorecard-finance, overall, methodology) make the resource concrete. It does not, however, distinguish this generic fetch from the specialized siblings get_question, get_scorecard, get_overall_results, and get_methodology, whose names suggest the same content, so an agent cannot tell from the description alone which to prefer.

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 only implied: 'Document ID from search' hints at the search-then-fetch workflow, and the single-document scope implies 'use once you know the ID.' There is no explicit statement of when to use this versus the per-document-type siblings, nor any exclusion or condition that would make the routing decision deterministic.

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