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

Annotations already cover the read-only, non-destructive, open-world profile, so the description's job is added context — and it delivers by enumerating the payload sections (header, fee/split data, contacts, custom fields) and noting they are returned 'as Bilflo returns them,' hinting at raw passthrough. It omits failure behavior (e.g., unknown job_id) which keeps it below 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?

Two short sentences, zero waste, with the core payload description front-loaded before the endpoint reference. Nothing is padded or redundant.

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 appropriately lists what the caller gets back (header, fee/split, contacts, custom fields), which is the key missing piece an agent needs. Only the absence of error/not-found behavior keeps it from a 5.

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 coverage is 100% and the single parameter already documents itself as the Bilflo direct hire job id. The description's 'GET /v1/DirectHires/{jobId}' only restates that the id is the path segment, adding little 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 (get) and resource (one direct hire), helped by the parenthetical gloss 'a permanent placement' that disambiguates the Bilflo term. The singular 'One' signals fetch-by-id versus the list-style siblings, though the contrast with bilflo_get_contract_job is only implied by naming rather than stated.

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: retrieve a single direct hire by its job id. There is no explicit when-to-use/when-not, no mention of when to prefer bilflo_get_contract_job for contract placements, and no statement of prerequisites such as required id validity.

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