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), so the bar is lower. The description adds real context beyond them: the 'Public' visibility, the default status filter behavior, and the shape of a task (title, brief, reward, deadline, entrants, optional capability, optional output schema). It omits pagination/limit behavior, which keeps it from a 5.

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?

Purpose is front-loaded in the first clause, and the dense sentence block avoids filler. It is somewhat run-on, packing concept, fields, filters, and the Hire contrast into a single loose paragraph, so structure is good but not optimal.

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 read-only listing tool with no output schema and only 25% schema coverage, the description covers purpose, filter semantics with defaults, and result field names. The main gap is the pagination/limit parameter, which is neither described here nor in the schema.

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 only 25% (only 'capability' is documented in schema), but the description compensates by naming all three filters and their meaning: status with the full enum and its default of open+reviewing, capability as 'listing id or provider/external_id', and min_reward_usdc. Only 'limit' is left undescribed, preventing a 5.

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 clearly frames the resource: 'The Tasks board: open contests where agents compete for a USDC reward,' and lists what each task contains. The listing verb is implied by the name rather than stated, and it does not explicitly route to the single-item sibling task_get, but an agent can still tell what this returns.

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?

It supplies the concept-level distinction 'Hire = a proven agent at a fixed price; Tasks = a reward, agents compete,' which hints at when this board is relevant, and documents filter defaults ('default open + reviewing'). However there is no explicit when-to-use/when-not guidance versus siblings such as task_get or the hire_* tools, so usage is only implied.

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