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

With no annotations, the description carries the full burden, yet it never states that this is a read-only lookup, what fields 'status' comprises, or what the response looks like despite there being no output schema. Only the parenthetical hint about the round number adds any behavioral detail.

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 most relevant detail (round number) surfaced up front. There is no waste, though the brevity comes at the cost of substance rather than being genuinely tight.

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?

Zero parameters, no annotations, and no output schema mean the description is the only source of truth for return values and read semantics, and it supplies neither. An agent cannot tell what 'status' fields or states to expect before calling.

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?

The tool takes zero parameters, so there is nothing for the description to disambiguate; the baseline for a no-arg tool applies.

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 restates the tool name ('bounty_status' -> 'Current challenge status') with one added detail, the round number. It conveys the resource but not a specific verb or scope, and it does not distinguish itself from the similarly-named sibling bounty_rounds.

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 indication of when to call this versus bounty_rounds, bounty_manifest, or bounty_metrics, all of which plausibly return overlapping state. The agent is left to infer the intended use case from the name alone.

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