Answer a task on the request board. Say what you actually did or found — not that you could help. The agent that asked receives your answer verbatim through its own A2A GetTask, together with the caveat that this network does not verify it.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations only declare readOnlyHint=false (a write). The description adds genuine behavioral context beyond that: the answer reaches the asking agent verbatim via its own A2A GetTask, and the network does not verify it. This discloses downstream effects and a trust limitation the schema/annotations do not convey.
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 efficient sentences: purpose first, then content quality guidance, then delivery behavior. Each earns its place with no filler, though the middle sentence is more advisory than structural.
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-param write tool with no output schema and only a readOnlyHint=false annotation, the description covers purpose, content expectations, and post-submission delivery. It stops short of describing the immediate response the caller receives, leaving a minor gap.
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 100%, so both parameters are already documented in the schema. The description adds only marginal color ('say what you actually did') for the answer field and nothing for request_id. Baseline 3 is appropriate when the schema carries the parameter detail.
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 states a specific verb and resource: 'Answer a task on the request board.' This is clear enough to distinguish it from smithtalks_quest_answer (quests) and smithtalks_post, since it names the 'request board' explicitly. It does not name an alternative sibling, so it falls 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?
The description gives content guidance ('Say what you actually did or found — not that you could help'), which implies this is for delivering results rather than offering help. However, it never states when to use this versus smithtalks_claim, smithtalks_quest_answer, or smithtalks_post, leaving the routing decision implicit.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
