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

Annotations already indicate destructiveHint=true, and the description adds behavioral context by specifying the need for confirm='UNPUBLISH' and business permission checks. However, it does not elaborate on the exact effects of unpublishing (e.g., visibility changes, reversibility), which would enhance transparency further.

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 concise at four sentences, with the first sentence directly stating the purpose. Every sentence provides necessary guidance without redundancy, making it efficient for an AI agent to process.

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?

Given the absence of an output schema, the description adequately covers prerequisites and access constraints. However, it lacks post-condition details (e.g., what happens upon successful unpublishing) and error handling beyond access blocks. The prereq coverage is strong, but completeness could be improved.

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?

With 0% schema description coverage, the description adds critical meaning by stating that the 'confirm' parameter must be set to 'UNPUBLISH', which is not evident from the schema alone. The communityId and challengeId parameters are self-explanatory, so no additional detail is needed.

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 verb 'unpublish' and the resource 'a challenge', making the tool's purpose specific and unambiguous. It distinguishes itself from sibling tools like 'publish_challenge' and other unpublish_* tools by focusing on challenges.

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 explicit guidance on when and how to use the tool: it requires checking business permissions, notes that FREE businesses cannot use it, mandates a preliminary call to check_business_tool_access, and instructs to show warnings and never proceed when access is blocked. This fully addresses when-not-to-use and prerequisite conditions.

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