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

Goes well beyond the readOnly/openWorld annotations by disclosing the pricing model ($0.002 USDC per successful call, paid via x402 on Base, Solana or Arc) and that failed calls are not charged. It also states the page granularity (~20 per page) and that a total match count is returned, which materially affects how an agent budgets and paginates.

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 and scope are front-loaded, and the cost sentence at the end earns its place. The middle enumeration of return fields is slightly dense and partly duplicates the output schema, but nothing is wasted or buried.

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 an output schema present, the field-by-field enumeration is redundant, but the description supplies everything else an agent needs: filtering options, page size, total count, and cost/payment behavior. Complete for correct invocation, just mildly over-specified on the return shape.

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%, so all four parameters are already documented with examples. The description restates their meaning (keyword, optional location, optional remote-only filter) and adds only the ~20-per-page figure, which is marginal value over the structured fields.

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: tech job listings from Dice (US) for a keyword plus optional location, and enumerates what each listing contains. The named source (Dice) and tech-only scope are enough to tell it apart from the dozens of sibling job-board tools without opening a schema.

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 by the source and scope (US tech jobs, keyword search, optional remote-only or location filter) but there is no explicit when-to-use or when-not-to-use guidance and no routing to alternatives like a multi-job-board aggregator. An agent must infer selection from the source name alone.

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