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

Annotations already cover safety (readOnlyHint) and reach (openWorldHint). The description adds real context beyond them: the source is credential-free public ATS JSON, and the listing returns only a short description rather than full job detail. It stops short of stating pagination limits or rate behavior, but adds substantive value.

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?

Dense but front-loaded: the core action and paging come first, then parameter derivation, then the sibling routing. No sentence is wasted, though the URL/format parenthetical is slightly packed.

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 description needn't explain return values, and it correctly signals that listings are short and that full detail requires the sibling. Credential and safety context are covered by description plus annotations, leaving only minor gaps like paging defaults.

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%, so the baseline is 3, yet the description adds meaning the schema lacks: it explains that host and site are extracted from the careers URL pattern, that host must be an *.oraclecloud.com hostname, and that site resembles 'CX_1'. This exceeds what the terse schema descriptions convey.

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 ('Lists ... public requisition rows') and pins the platform (Oracle Recruiting Cloud tenant). It explicitly distinguishes itself from the sibling single-item tool, so an agent can pick it without opening either 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?

Names the alternative explicitly ('Use jobs_oracle_job to get a single ... requisition') and gives the condition that selects it ('for full detail'), with the implicit complement that this tool is for listing. Routing is unambiguous.

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