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

With no annotations present, the description carries the full disclosure burden and does well: it reveals a third-party scraper source, up to 1 h caching, a hard cap of 50 results, and a per-call price of 0.02 USD via x402. It stops short of covering failure modes or what happens when a paid call returns nothing, which matters for a metered tool.

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?

Four dense sentences, front-loaded with scope and return fields, followed by operational facts (limit, provider, caching, price). No filler, though the provider and price facts could be merged for tighter structure.

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?

There is no output schema, so the description correctly compensates by naming the returned fields. The commercial framing (paid per call, third-party seller) is present, which an agent needs before invoking. Missing only error/empty-result behavior for a metered third-party endpoint with 11 optional parameters.

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 every one of the 11 parameters is already documented in the schema. The description adds only marginal semantics ('salary (where shown)', 'up to 50 jobs per call' reinforcing the maxItems clamp) and does not explain sort, jobType, or datePosted behavior beyond the schema.

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 ('Live Indeed job listings') and enumerates both geographic scope (Denmark, Sweden, Norway + 57 other country sites) and the exact fields returned. No sibling tool in the list does anything similar, so there is no ambiguity to resolve.

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?

The description establishes clear usage context: keyword or location driven search, up to 50 jobs per call, and cached results. It doesn't state any when-not-to-use condition, but with an unrelated sibling set (dk_address, fx_dkk, mica_casp, etc.) there is no competing tool to steer away from.

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