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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so the safety profile is covered. The description adds a genuinely useful disclosure about data-exposure boundaries (no raw artifacts, unpublished output, review notes, or bucket keys), but says nothing about the observation_limit cap, pagination, or behavior on an unknown report_id.

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 what is returned before the exclusion clause. No filler, though the second sentence is a generic privacy guarantee that is only marginally specific to this tool.

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?

An output schema exists, so return-value explanation is not required, and annotations cover safety. However, with 0% parameter description coverage and no usage guidance across five sibling tools, the definition leaves real gaps an agent would need to close.

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 0%, so the schema documents neither parameter's meaning; the description must compensate but does not. 'Bounded observation projection' hints at observation_limit yet never states the default, maximum, or what happens when observations exceed the limit, and report_id's format constraints are left entirely to the schema pattern.

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 gives a specific verb and resource ('Returns one published report revision') plus the scope of the observation projection, so an agent knows exactly what it retrieves. It stops short of naming or contrasting any sibling (e.g. get_methodology, get_data_coverage), so it does not fully differentiate itself within the family.

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 statement of when to call this tool versus the alternatives, nor any prerequisite or precondition. The sibling names suggest plausible overlaps (methodology, coverage, latest prices) that the description never resolves.

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