discord_delete_forum_post

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

Annotations already indicate destructiveHint: true and readOnlyHint: false. Description adds context of irreversibility ('IRREVERSIBLE') and permission requirements, which aligns with annotations. No contradiction.

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 sentences, front-loaded with action and irreversible warning. No unnecessary words. Every sentence adds value.

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 simplicity of the tool (one parameter, no output schema, clear annotations), the description is complete. It covers purpose, irreversibility, permission, and alternative action. 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?

Only one parameter 'thread_id' with schema description that already explains it's a snowflake ID. Since schema coverage is 100%, the description adds no extra semantics beyond the schema, but it is sufficient. 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?

The description clearly states the tool deletes a forum post and all messages. It uses a specific verb ('delete') and resource ('forum post'), and distinguishes from the sibling tool 'discord_update_forum_post' which archives instead.

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?

Explicitly tells when to use this tool vs. alternatives: 'To merely close it without deleting, use discord_update_forum_post with archived:true'. Also mentions required permission: 'Requires the Manage Threads permission (or thread ownership)'.

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