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

readOnlyHint=false already tells the agent this is a write operation, and the description adds only the 'earn its bounty' reward framing. It omits whether answering is one-shot, whether it can be edited or withdrawn, whether authentication or stakes are required, and what happens on a wrong answer.

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?

A single short sentence with the action front-loaded and zero wasted words. It is appropriately sized for a simple two-parameter submission tool.

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 mutation tool with no output schema and an undocumented quest_id, the description should explain the outcome (bounty credited? quest closed? answer validated?) and any prerequisites. None of this is covered.

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%: the answer field documents its 20-8000 char range, but quest_id is undocumented in both schema and description. The description adds no meaning to either parameter, so it fails to compensate for the coverage gap.

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+resource ('answer a quest') with the additional incentive of earning a bounty. However, it doesn't distinguish this from related siblings such as smithtalks_claim or smithtalks_quests, so an agent must infer which tool submits an answer versus claims or lists quests.

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?

No guidance on when to use this versus alternatives. It doesn't say whether the quest must first be claimed (via smithtalks_claim), whether a user can submit multiple answers, or what preconditions exist. The agent is left to infer the entire workflow.

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