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

Annotations already declare readOnlyHint, openWorldHint and destructiveHint=false. The description goes beyond them by disclosing the admin/moderator permission requirement, the feature-flag precondition ('Spaces do not accept submissions unless the Space turned them on'), and the API-key auth requirement.

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 opening two sentences restate the same content twice — 'answers, posts and questions followers submitted... waiting for review' followed by 'Lists the submissions in the Space inbox: answers, posts and questions followers sent for consideration'. Front-loaded but with visible redundancy that wastes space.

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 single-parameter read tool with no output schema, it covers permissions, preconditions, auth and the follow-up workflow. Nothing essential to calling it correctly is missing, though the redundant framing slightly dilutes the signal.

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 coverage is 100%, so space_id is already documented as 'Space ID from list_my_spaces'. The description mentions submission_id, but that belongs to the sibling review tool, not this parameter set. Baseline 3 applies when the schema carries the semantic load.

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 (lists) and resource (Space submissions/inbox: answers, posts, questions awaiting review). An agent can distinguish this from siblings like quora_list_answer_requests or quora_review_space_submission without opening the schema.

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?

Provides meaningful context: 'Admins and moderators only', the precondition that submissions must be turned on, and routes to the sibling review_space_submission for processing one item. Lacks explicit when-not-to-use guidance, but the workflow routing is clear.

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