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

The description adds rich behavioral context beyond the annotations: it discloses the permission requirement, the scheduling effect (publishes at scheduled time or immediately if past), the in-app notification to the author, and specific error codes (400, 403, 404). This fully informs the agent of consequences and failure modes.

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 concise and well-structured, delivering purpose, permissions, behavior, errors, and usage guidance in four tight sentences. No filler or redundancy; each clause contributes actionable information.

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 mutation tool with no output schema, the description covers all necessary context: when to use it, prerequisites, side effects, error conditions, and target state. Nothing essential is missing for an agent to invoke it correctly.

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?

The input schema already documents postId 100% with 'The post ID to approve.' The description does not add additional meaning about the parameter beyond what's in the schema, so 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 states a specific verb ('Approve') and resource ('a post awaiting team approval'), and further clarifies the exact condition ('approvalStatus pending'). It implicitly distinguishes itself from siblings like reject_post and publish_post by focusing on the approval workflow step.

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 includes an explicit usage directive: 'Use this when the user (an owner/admin/approver) wants to approve a post awaiting team approval.' It also specifies the required role. It does not explicitly name reject_post as the alternative for the opposite action, but the when-condition is unambiguous.

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