discord_delete_forum_post

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

Annotations already signal destructiveHint=true. The description adds behavioral context: 'IRREVERSIBLE' emphasizes permanence, and 'Requires the Manage Threads permission' informs about authorization needs. This adds value beyond annotations.

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?

Only two sentences and one warning sentence, all essential and front-loaded. No redundant or unnecessary information.

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 a single required parameter, no output schema, and full schema coverage, the description covers purpose, usage guidance, behavioral traits, and permissions adequately. No gaps.

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 a clear description and pattern for thread_id. The description does not add extra parameter details beyond the schema, so baseline 3 is appropriate.

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?

Description explicitly states 'Permanently delete a forum post (thread) and all its messages', clearly identifying the verb and resource. It also distinguishes from the sibling tool 'discord_update_forum_post' by mentioning the alternative for closing vs deleting.

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?

Directly provides an explicit alternative: 'To merely close it without deleting, use discord_update_forum_post with archived:true.' This tells the agent when not to use this tool and which tool to use instead.

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