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

Annotations already declare readOnlyHint=false and destructiveHint=false, so the mutation profile is partly covered. The word 'Replace' adds useful context that existing text is overwritten, and 'approve it for publishing' discloses a state transition. However, it says nothing about permissions, reversibility of approval, or side effects on the publishing pipeline.

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?

A single tight sentence with the action front-loaded and zero filler. It is efficient, though extremely brief for a tool with four undocumented parameters.

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 write-and-approve mutation with no output schema and four parameters at 0% schema coverage, the description is too thin. It does not explain parameter roles, approval consequences, or expected results, leaving significant gaps the structured fields do not fill.

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% across four required parameters (projectId, siteId, postId, body), and the description adds no mapping to them. It only obliquely refers to 'a post's text', leaving the identity/scoping parameters entirely unexplained in prose.

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 names a specific verb ('Replace') and resource ('a post's text') plus a distinct second action ('approve it for publishing'). This separates it reasonably from siblings like approve_distribution_posts and regenerate_distribution_post, though it does not explicitly name those alternatives.

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?

There is no when-to-use guidance, no prerequisites, and no reference to the sibling tools that handle approval-only (approve_distribution_posts) or rewrite-only (regenerate_distribution_post) workflows. The agent must infer selection from the description alone.

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