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

Annotations already declare readOnlyHint=true and openWorldHint=false. The description adds real behavioral context beyond them: the call is free, competitors are counted but not named, and an un-analyzed posting returns status 'building' with retry_after_seconds. That retry/async detail is exactly the kind of trait annotations cannot express.

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?

Front-loaded with the comparison purpose, then identification, then the async/free caveats. The opening metric list is dense but every clause maps to a returned field, so it earns its place; only mild trimming is possible.

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?

For a read-only tool with no output schema and six loosely-required params, the description covers what it returns, how to identify the posting, the 'building' state, and cost/privacy caveats. The main lingering gap is param precedence and how to disambiguate multiple matching postings.

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?

With only 50% schema coverage and 0 required parameters declared, the schema alone is ambiguous. The description resolves this by mapping parameters into alternative identification sets (URL, job_id, or employer+title+city+state), telling the agent that any one set suffices. It still doesn't state precedence when multiple sets are supplied, keeping it short of 5.

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+resource: comparing one open US healthcare clinical posting against its local market, and enumerates the exact metrics returned. It implicitly distinguishes itself from hiring_market (which is presumably broader) by emphasizing 'one ... posting', though it never names the sibling to sharpen the contrast.

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?

Gives three concrete ways to identify the posting (careers-site URL, VeritaHire job id, or employer+title+city/state), which is genuine usage guidance. However it never states when to prefer this over hiring_market or is_job_still_open, so the routing to alternatives is left to inference.

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