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

Annotations indicate this is a write operation (readOnlyHint=false) and not idempotent, but the description adds the key behavioral consequence: 'Once approved, it will be published at the scheduled time.' This goes beyond the structured annotations by clarifying the downstream effect, though it does not discuss reversibility or permission requirements.

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 description is two sentences, front-loaded with the primary action and followed by a concise consequence. Every word earns its place, with no redundant or vague filler.

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?

Given the simple input schema, strong annotations, and no output schema, the description provides sufficient context: it names the resource, the condition ('pending approval'), and the post-approval behavior. It does not mention return values, but for an action-oriented tool this is not a critical gap.

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%, with clear descriptions for postId, comment, and team_id. The tool description itself adds no parameter details, but because the schema already thoroughly documents each parameter, the baseline score of 3 is appropriate.

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 clearly states the specific action: 'Approve a scheduled post that is pending approval,' identifying both the verb and resource. It also explains the outcome ('published at the scheduled time'), but it does not explicitly differentiate from the sibling tool reject_post, so it stops short of a 5.

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?

The description implies the usage context: it is for approving pending scheduled posts. However, it does not provide explicit guidance on when to use this tool versus alternatives such as reject_post or list_pending_approvals, nor does it mention exclusions or prerequisites.

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