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

Annotations already declare destructiveHint=true and idempotentHint=true, so the safety profile is partially covered. The description adds value beyond that: the deletion is permanent, it extends to attached files, it breaks the share link, and it is restricted to the owner, none of which appear in the annotations. It does not say what happens on a permission failure or a missing quest, which keeps it off a 5.

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?

Four short sentences with zero filler, front-loading the permanence and file destruction before the permission constraint and the confirmation requirement. Every clause carries actionable 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?

For a two-parameter destructive tool with rich annotations and no output schema, the definition covers destruction scope, side effects, authorization, and required user confirmation. Only the failure behaviour and any return payload are unaddressed, which is acceptable given the annotation coverage.

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%: edit_token is documented in the schema but quest_id is not. The description does not describe quest_id semantics either, though the name is self-evident, and the 'Owner only (co-editors cannot)' line indirectly clarifies that an edit token does not confer delete rights. That indirect hint is the only meaning added beyond the schema.

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 specific verb and resource ('Permanently delete a quest') plus the scope of deletion ('and its files'), which immediately separates it from every sibling tool, none of which remove a quest. An agent knows exactly what this tool does without opening the schema.

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?

Gives a real precondition ('Owner only (co-editors cannot)') and a procedural requirement ('Confirm with the user first'), which is the correct usage guidance for a destructive operation. It does not name a sibling alternative, but for an irreversible delete there is no competing tool to route to, so the omission is minor.

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