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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint, and destructiveHint=false, so the safety profile is fully covered structurally. The description adds nothing beyond them: no auth/permission requirements, no behavior when the document ID is unknown, no note that it resolves the latest revision rather than a specific one. It does not contradict the annotations.

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?

A single short sentence, front-loaded and free of filler. It is efficient, but because it merely mirrors the title it earns less than a maximally useful one-liner would.

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 two-parameter read with full annotation coverage and a complete schema, this is roughly sufficient. However, with no output schema, the description only vaguely gestures at the return ('document and its current revision') without indicating what that payload contains, leaving a minor gap.

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% with two fully documented parameters (company UUID, document ID pattern), so the schema carries the semantics. The description's mention of 'company knowledge document' loosely maps to the two params but adds no format or constraint detail. Baseline 3 applies.

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 (Read) and resource (one company knowledge document plus its current revision). The phrases 'one' and 'current revision' implicitly separate it from knowledge_list (many documents) and knowledge_history (all revisions), though no sibling is named. It is a verbatim duplicate of the title, so it adds no clarifying detail of its own.

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?

There is no explicit when-to-use, when-not-to-use, or named alternative. The only hint is 'current revision,' which weakly implies using knowledge_history for older revisions, but nothing is stated. An agent must infer selection from the sibling names alone.

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