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

No annotations are provided, so the description carries the full burden. It does disclose a genuine behavioral trait — rate limiting on attempts — which is exactly the kind of constraint an agent needs. It says nothing, however, about what a submission returns, whether wrong answers consume attempts, or what the failure/cooldown behavior looks like.

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?

Two short sentences, no filler, and the core action is front-loaded ahead of the constraint. Nothing here could be cut without losing 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?

With no annotations and no output schema, the description should explain the outcome of a submission and what the optional log parameter does in this flow. It instead stops at the action and the rate limit, leaving an agent unable to predict or interpret the result.

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%, so code, answer, and the optional log note are already documented. The description adds only the loose framing of "your current stage" and no format or vocabulary detail (e.g. case sensitivity, accepted answer types) 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?

The verb+resource are directional ("submit an answer"), but "your current stage" is undefined — stage of what, and how does it relate to a cache? The title "Answer a cache" supplies the missing resource, but the description itself leaves the agent inferring the domain from siblings like view_cache and get_join_challenge.

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?

"Limited attempts per hour" hints this is a consequential action, but there is no when-to-use guidance, no prerequisite (e.g. retrieve the cache via view_cache first), and no routing against alternatives such as log_cache_note or flag_content.

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