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

Annotations already declare destructiveHint=true, idempotentHint=false, and openWorldHint=true, so credit is for added context: the description discloses irreversibility ('cannot be unpublished by this server') and the Final Review gating requirement. What is missing is any mention of what a successful call returns or how partial failures surface.

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?

Three compact sentences, front-loaded with the action, then preconditions, then the irreversibility caveat. Every sentence carries information an agent needs before invoking a destructive publish.

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 two-parameter destructive mutation with no output schema, the definition covers preconditions and consequences well. It stops short of describing the success response or what a refused call looks like, which an agent might want before committing to an irreversible action.

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 coverage is 100%, with both parameters documented, including confirm's refusal behavior and contentItemId's source tools. The description reinforces the confirm requirement but adds no syntax or identifier format beyond what the schema already provides, so the baseline 3 applies.

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 and resource: 'Publishes one saved calendar post to its network immediately'. This clearly distinguishes it from schedule_post, which queues rather than publishes, so an agent can tell the two apart without reading schemas.

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?

Gives clear preconditions: confirm must be true and the post must have passed Final Review. It does not explicitly contrast with schedule_post or list_upcoming_posts as the alternative path, but the usage context for the tool is otherwise unambiguous.

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