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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds only the freshness nuance of "latest," and says nothing about what "owner document" means or what happens when no document exists. With annotations carrying most of the burden, this is adequate but thin.

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, front-loaded sentence with no filler or repetition. Brevity is appropriate, though it is under-specified rather than maximally efficient.

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 carries responsibility for describing what is returned (document body? metadata? which fields?), and it does not. The meaning of "owner document" and its relationship to the embedded app remain unexplained.

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% for the single required 'id' parameter, so the description must disambiguate it — yet it never says whether the id is a document id or an app id. Combined with "owner document," this leaves the caller guessing what entity they are addressing.

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?

It states a verb (read) and a resource (document) scoped to an embedded app, which is more than a tautology. However, "owner document" is opaque, and nothing distinguishes it from siblings like get_document, show_document, or get_document_sharing — an agent cannot tell which read variant applies.

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 when-to-use guidance and no mention of alternatives despite thirteen sibling document tools. The phrase "for the embedded app" hints at a context but never states the condition under which this tool is preferred over get_document.

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