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

With no annotations, the description carries the full load and does so well for a destructive operation: it discloses irreversibility once claimed, the precondition, and the financial side effect (full refund on paid quests). Missing are permission/auth requirements and what happens on a repeat call or on an already-claimed quest.

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?

Three short sentences, front-loaded with the action and precondition, then the monetary consequence, then the hard limit. Nothing is redundant and nothing needs rereading.

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 one-parameter destructive tool with no annotations and no output schema, the description covers the essentials an agent needs: when it is legal, what gets reversed, and what is permanent. Error/edge behavior (nonexistent id, already-cancelled id, idempotency) is the only notable omission.

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 0% and the description adds no meaning about quest_id — no format, no source (e.g. from list_quests or get_quest). The parameter is self-evident for a single-id cancel tool, so the gap is minor rather than disabling.

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?

A specific verb+resource ('Cancel a quest') with an explicit scope qualifier ('before a quester claims it'). It is distinguishable from approve_quest/create_quest by the verb, but the description never names or contrasts with any sibling, so it stops short of a 5.

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 clear use condition (pre-claim) and an explicit exclusion (claimed quests cannot be cancelled). It does not point to any alternative action for claimed quests, such as dispute_quest, which would be the natural routing fallback.

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