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

With no annotations, the description carries the full behavioral burden. It discloses two useful traits — that the call is 'Free' and that the payment methods reflect state 'enabled right now' (i.e., dynamic, current data). It does not state that it is read-only, whether results are cached or rate-limited, or how the pricing data is structured.

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?

One front-loaded sentence enumerating exactly the three data groups returned, followed by a one-word cost note. No filler, nothing repeated from structured fields.

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 output schema, the description must convey the return shape, and it largely does by naming the three categories of information returned. It is slightly thin on the granularity of each (e.g., is a 'task type' a slug, a label, a category?) but adequate for a zero-parameter read-only listing tool.

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 of 4 applies. There is no filter or formatting knob for the description to explain, and the description correctly implies a single unfiltered listing.

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 ('List') and three concrete resources (task types, bounty floors in card + USDC, enabled payment methods). It is clearly distinct from siblings like sidequest_list_tasks or sidequest_stats by virtue of being a static pricing/capability reference, though it never explicitly names a sibling to differentiate itself.

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?

Usage is implied rather than stated: an agent can infer this is the tool to call when it needs to know accepted task types, bounty minimums, or which payment rails are live. There is no explicit 'use this when...' or exclusion against sidequest_stats, which also returns ecosystem-level information and could be confused with it.

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