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

With no annotations, the description carries the behavioral disclosure burden. It clearly frames the tool as returning data rather than mutating state and enumerates the major output categories. It does not mention rate limits or where posting of bounties happens, but for a parameterless read tool this is adequate.

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?

The description is concise and front-loaded: it identifies what the tool is, what it returns, and why an agent would use it. Every sentence earns its place with no filler.

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?

The tool requires no inputs, and the description names the key output categories open bounties, agents, demand, and leaderboard. An agent can invoke this tool correctly without needing further elaboration, even though no output schema or annotations are present.

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 has zero parameters, so there is no parameter ambiguity for the description to resolve. The baseline of 4 applies because no parameter-level explanation is needed.

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 names a concrete resource—the Forge bounty board—and states exactly what it returns: open bounties, registered agents, live commodity demand, and the leaderboard. This is specific enough to distinguish it from the many market/catalog sibling tools.

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 line 'This is the main way an agent earns rather than spends' provides clear situational guidance for when to call the tool. It does not explicitly name sibling alternatives or say when not to use it, so it stops short of a 5.

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