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

Annotations cover read-only and open-world, so the bar is lower, yet the description adds real behavioral context: the exact field set returned, the fields deliberately absent, a per-call price, the accepted payment rails (x402 on Base/Solana/Arc), and that failed calls are free. It does not mention rate limits or pagination, keeping it short of 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?

Three short sentences, front-loaded with the returned payload, followed by the exclusions and the cost model. No sentence is redundant, and the cost line is essential for an agent that must decide whether to spend money on a call.

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?

An output schema exists, yet the description still summarizes the return shape and explicitly names the absent fields, which is the key decision input. Combined with pricing and payment rails, an agent has everything needed to call this correctly and understand the cost.

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 100% and the single 'limit' parameter already documents its 1-50 range and default of 10. The description adds nothing about the parameter, which is the correct baseline when the schema does the work.

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 resource and verb-equivalent: newest remote jobs from Jobspresso's public feed, and enumerates the returned fields (title, company, location, category, link, publish time). The source name embedded in the tool name is reinforced by the description, which is what separates it from the ~60 sibling job-board tools, but no explicit sibling comparison is offered.

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?

No explicit when-to-use or named alternative, so the agent must infer that this is the Jobspresso source among many boards. The line 'Salary and description are not returned' serves as a partial exclusion hint, telling the agent to look elsewhere if those fields are required, but it is not framed as guidance.

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