discord_delete_message

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

Beyond the destructiveHint and readOnlyHint annotations, the description adds concrete behavioral details: the action is IRREVERSIBLE, permission depends on message ownership, and the optional reason is recorded in the audit log. These disclosures help an agent anticipate side effects without relying on structured fields alone.

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?

All sentences are short and information-dense, with the core action and irreversibility warning front-loaded. The alternative-tool routing and permission note each earn their place; there is no fluff or repetition.

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 simple single-message delete operation, the description covers the action, destructiveness, permission requirements, the relevant alternative, and the audit-log side effect. No output schema exists, and none is needed for an agent to invoke this tool correctly.

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 description coverage is 100%, with all three parameters already documented with descriptions and patterns. The description only restates the audit-log effect of the reason parameter, already present in the schema, so it adds no new parameter-level meaning. 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 opens with 'Permanently delete one specific message', a clear verb+resource+scope statement. It distinguishes itself from bulk deletion and other delete-related siblings by emphasizing 'one specific message'.

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 names discord_bulk_delete_messages as the alternative for removing many messages at once. It also states the permission prerequisite: the bot can always delete its own messages, while deleting another user's message requires Manage Messages permission. This gives clear when-to-use and when-not-to-use guidance.

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