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

Annotations already declare readOnly, idempotent, non-destructive, non-open-world. The description adds genuine context beyond that: it notes the object is returned exactly as publicly served and discloses that freshness, confidence and relations come back as 'not established or not published', which tells the agent what to expect in the payload.

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 front-loaded sentence that leads with the primary return value and defers secondary detail to a parenthetical. It is dense but earns its words; no filler.

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 structure needn't be spelled out, and annotations cover the safety profile. The description adds the governance-view caveats, making it reasonably complete for a single-object read, though the absence of parameter and sibling-routing detail is 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 only 33% – only 'id' is documented (as listed by list_objects), while 'type' and 'namespace' carry no schema description. The description adds nothing about any parameter's format, allowed values, or role, so it fails to compensate for the coverage gap.

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+resource: returning one public governed object plus its governance view. It is clear what the tool produces, but it does not differentiate itself from the sibling 'fetch' or explain why one would use get_object over fetch, so an agent must infer the boundary.

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 guidance, no when-not-to-use conditions, and no alternatives named. The siblings fetch/search/list_objects are never referenced, so routing between them is left entirely to inference.

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