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

Annotations already cover the safety profile (readOnly, idempotent, non-destructive), so the description's added value is content semantics: which items appear and the notable aggregation rule that the project-total oversize is reported as a project-scope item. It does not mention pagination behavior even though a result_offset parameter exists, which is a real gap for a list tool.

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 dense sentence, front-loaded with the resource and then the enumeration, with zero filler. The equivalence note is tacked on at the end and earns its place.

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?

With no output schema the description does explain the content of the returned list well, including the project-scope item convention. But for a paginated read tool with a completely undocumented schema it omits both parameter meanings and any hint that results can be paged.

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 description must carry the burden for both parameters, and it says nothing about project_id or result_offset. It neither explains what project_id accepts nor that result_offset is a pagination cursor, leaving the agent to infer both.

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 names the resource and enumerates exactly what counts as an 'attention item' (empty/unchanged templates, access-register discrepancies, oversized documents, undocumented keys), which makes the scope concrete. It lacks an explicit verb, but the intent is unambiguous and clearly distinct from the read_* document/method siblings.

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?

By stating it returns 'the same list as the attention field of read_project' it implicitly points at the alternative and lets an agent choose the narrower call, which is genuinely useful routing information. However, it never says when to prefer this over read_project (e.g. to avoid a full project read) nor any exclusions or prerequisites.

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