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

Annotations already cover the safety profile (readOnlyHint=true, destructiveHint=false, openWorldHint=false), but the description adds real context beyond them: that a listed or owner-accepted bounty is still unpaid and that payout happens owner-side, outside this system. That is exactly the kind of economically important caveat an agent cannot derive from structured fields.

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, purpose front-loaded, no filler or restated name/title. The closing phrase 'payout is owner-run and off' is clipped to the point of being slightly awkward, which costs a point but the density is otherwise excellent.

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 zero-argument, read-only list tool with no output schema, the description covers purpose and payment semantics but says nothing about what a listing actually contains (fields, count, filtering/ordering, pagination). Adequate, but an agent does not know what it will receive back.

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 the baseline is 4. The description correctly implies a single unfiltered listing call and does not promise filtering semantics that do not exist, though it also adds no parameter guidance (none 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?

States a specific verb and resource ('List public owner-posted work bounties') with an explicit scope qualifier (public, owner-posted). It implicitly separates itself from voidly_bounty_status/claim/submit, which operate on a single bounty, though it never names those siblings directly.

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?

There is no when-to-use guidance, no exclusions, and no routing to the obvious alternatives (voidly_bounty_status for a specific bounty, voidly_bounty_claim/submit for acting on one). The use case is only inferable from the verb 'List'.

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