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 goes further with genuinely useful behavioral detail: membership is re-evaluated per request, revocation blocks search/downloads even with an existing session, org API keys stay within existing grants, and responses are private/no-store. Much of it reads as general team-access policy rather than this operation's specifics, which keeps it short of a 5.

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?

The one-sentence purpose is front-loaded, but it is followed by roughly seven sentences on sharing semantics and CSRF/origin checks that are largely about sharing, publishing and revocation tools rather than about reading an answer. Several sentences do not earn their place in this specific tool's description.

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 read-only tool with no output schema and full schema coverage, the description should at minimum say what comes back. It states only 'an answer and its source versions' and spends the rest on authorization policy, so return shape and any pagination/size behavior remain unspecified. Adequate but with clear gaps.

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 100%, so base_id, question_id and organization_id are already documented in the schema, including the OKFIndex/membership requirement for organization_id. The description adds no additional meaning about parameter format, relationship between question_id and the returned answer, or constructors. Baseline 3 applies.

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 opening sentence gives a specific verb and resource: 'Read an answer and its source versions.' That is considerably better than a tautology, but it never names or distinguishes itself from close siblings such as team_get_base_document, team_read_base_source, or get_base, so an agent cannot tell from the text alone which of these to pick.

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 statement, no prerequisite ordering, and no named alternative. The bulk of the text describes access-control mechanics rather than telling the agent when this tool is the right choice, leaving selection to inference from the name.

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