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

Annotations already declare readOnlyHint=false, destructiveHint=false, openWorldHint=true, so the agent knows this is a non-destructive external write. The description adds the meaningful confirmation requirement ('Show the user each post first') and the social-publishing target, but says nothing about reversibility, what approval triggers, or whether it can be undone.

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?

Two short sentences with the core action front-loaded and the safety instruction second. Nothing is padded or redundant.

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?

Annotations cover the safety profile and no output schema is required, so the main gap is the undocumented parameters and the absence of any statement about what approval actually does (schedule? immediate publish?). Adequate but thin for a state-changing batch operation.

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 0% for three required parameters, so the description carries the full burden and largely fails it. 'posts' loosely hints at postIds, but projectId and siteId are never explained, nor is the 200-item cap or that the array is a batch operation.

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 (Approve) and resource (distribution posts) plus the consequence (publishing to the user's social accounts), which is enough to tell it apart from reject_distribution_posts and edit_distribution_post by verb alone. It does not explicitly name a sibling, so it falls 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 line 'Show the user each post first' is a genuine usage rule about presentation before invocation, but there is no guidance on when to approve versus reject or edit, nor any precondition about post state. Usage is implied rather than stated.

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