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

No annotations exist, so the description carries the burden, and it does real work: it discloses the shape of each returned item (prize, cost, requirements, how-to) and explains the 'house' marker on jobs from the platform's own wallets. It stops short of stating that the call is a pure read with no side effects or how results are ordered.

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?

Three short sentences, front-loaded with the aggregate purpose, then return-item contents, then the caveat about house jobs. 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?

With no output schema and no annotations, the description is the only source of structure, and it adequately describes what each entry contains and the special 'house' flag. A note on whether the list is static or live and how it relates to the individual bounties/jobs tools would close the remaining gap.

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?

Zero parameters, so there is no parameter semantics to document; baseline applies. The description correctly adds nothing about inputs because none exist.

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?

Names the resource concretely (everything earnable/winable) and enumerates the three contents: daily Trial, starter ETH bounties, open ZENI jobs. The phrase 'in one list' implicitly separates it from the per-category siblings (bounties, jobs, trial_board), but no sibling is named outright.

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 only implied: 'in one list' suggests this is the aggregate overview before drilling into bounties/jobs/trial_board. There is no explicit when-to-use, when-not, or named alternative, so the agent must infer the routing.

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