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

Annotations already flag this as a non-read-only, open-world, destructive-intent write, but the description adds genuine context the annotations cannot: that submitted details are transmitted to a US-hosted recruiter and that submission constitutes consent, with a privacy link. It does not explain post-submission behavior (confirmation, follow-up), which keeps it out of 5 territory.

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?

Three short sentences, front-loaded with the core action, then eligibility, then the consent notice. Every sentence carries distinct information, though the privacy sentence is slightly detached from the rest.

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 write tool with no output schema and a fully documented input schema, the description covers audience, consent, and data residency. It leaves the agent without any notion of what a successful submission returns or what happens next, but nothing required to invoke it correctly is missing.

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% and all 7 fields carry their own descriptions, so the schema does the heavy lifting. The description adds only indirect meaning about role targeting, which loosely maps to role_category, so the baseline 3 is appropriate.

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 ("Apply to Ruzora's talent network") and narrows the audience to LATAM software engineers seeking remote US-startup roles. It is clearly distinguishable from siblings like create_hiring_lead or request_demo, though it never names an alternative explicitly.

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 a concrete eligibility condition (software engineers in LATAM interested in remote USD positions with US startups), which tells the agent when this tool applies. It stops short of stating when not to use it or which sibling to pick for non-matching users.

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