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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is fully covered. The description adds the useful context that these are private Q&A attachments, but discloses nothing about return shape, ordering, or pagination, so it earns a modest 3.

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 short sentences with the purpose front-loaded are efficient, but the trailing sentence 'The Q&A answers from the deck plus these documents' is syntactically ambiguous and could be read as describing the return value or the feature rather than the tool behavior.

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 read-only list tool whose annotations cover safety and with no output schema to explain, the description is minimally adequate. It nonetheless omits what the parameter means and what a caller receives, which are the two remaining gaps an agent would want filled.

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% and the description never mentions the sole parameter 'slug' or that it identifies the target deck. With low coverage the description is expected to compensate, and it does not, leaving the parameter undocumented in both structured and unstructured text.

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 clear verb ('Lists') and a specific resource ('supporting documents attached to a deck's private Q&A'), with an example (RFP) that grounds the concept. It is distinct from most siblings, though it never names its natural counterpart remove_qa_document or aitho_add_documents to sharpen 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 when-to-use guidance, no prerequisites (e.g. the Q&A feature must exist or be enabled), and no mention of the sibling alternatives for adding or removing documents. Usage is only inferable from the verb.

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