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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It does add a permission requirement and an implied state precondition (the post must be awaiting approval). However, it does not mention whether the approval is irreversible, what side effects occur, or what the response format looks like—important gaps for an approval action.

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 with no wasted words—first sentence gives the core action and state, second gives the permission requirement. It is front-loaded with the main purpose and stays efficient.

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 one-parameter approval tool with no output schema, the description gives the essential context: what action is performed, when it applies ('awaiting team approval'), and what prerequisite must hold (approval permission). It doesn't specify return details, but for a straightforward state update, this is sufficient.

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 schema has 0% description coverage for the single parameter 'post_id', and the tool description does not explicitly define the parameter either. The meaning is strongly implied by the tool name and the phrasing 'a post,' but the description adds no direct semantic detail about the post_id field, so it only partially compensates for the schema gap.

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 action with a specific verb ('approve') and a specific resource ('a post'), and it includes the context of being 'awaiting team approval.' This is immediately distinguishable from sibling tools like reject_post (opposite action) and publish_post_now (which triggers publication rather than approval).

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 provides a clear scenario of when to use the tool: when a post is awaiting approval. It also mentions a prerequisite ('Requires approval permission in the team'). However, it doesn't explicitly mention exclusions or alternative tools, so it stops short of being fully prescriptive.

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