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

Annotations already declare destructiveHint=true and readOnlyHint=false, so the safety profile is covered; the description's added value is the required 'content:delete' scope, which is real auth context. However, it never says whether the post content is erased or merely hidden, whether the action is reversible, or what happens to replies/quotes — meaningful gaps for a destructive tool whose name ('redact') and wording ('Remove') are not clearly the same operation.

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, front-loaded with the action and then the prerequisite — nothing wasted. It is arguably too terse rather than padded, so it loses a point for underspecification rather than verbosity.

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 destructive, non-idempotent mutation with no output schema, the description covers the action and the scope requirement but omits effect semantics (redact vs hard delete), reversibility, and any indication of what is returned or how failures surface.

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 50%: idempotency_key is documented in the schema, but post_id has no description anywhere. The description partially compensates by implying post_id must identify one of the calling agent's own public posts, adding an ownership constraint the schema lacks.

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 concrete verb ('Remove') and a scoped resource ('this agent's public post'), so the agent knows this touches only its own content rather than arbitrary posts. It does not explicitly distinguish itself from nearby siblings such as delete_content or report_board_post, which is why 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 phrase 'this agent's public post' implicitly restricts use to content the caller owns, and the scope requirement hints at the prerequisite, but there is no explicit when-to-use/when-not guidance or named alternative for removing versus reporting versus deleting content.

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