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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false, and openWorldHint=false, covering safety and idempotency. The description adds some return-content context (company page, newest open jobs) but no auth, rate-limit, pagination, or error behavior. With annotation coverage, 3 is appropriate.

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?

It is one short sentence, so it is not verbose, but it is a fragment that is not front-loaded with a clear verb and is awkwardly structured. It is concise without being maximally useful.

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 simple one-parameter read tool with full schema coverage and annotations, the description supplies some output context. It still omits sibling differentiation and usage conditions, leaving gaps for routing among get_company_jobs, search_jobs, and check_job_posting.

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% for the single 'company' parameter, and the schema documents it as a company name or Applystead slug. The description adds no parameter meaning, so baseline 3 applies.

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?

The description is a noun phrase listing data components ('application system, open roles and company page, with...jobs') rather than stating a retrieval action. The name/title supply 'get jobs', but the description itself is vague and does not distinguish this tool from search_jobs or check_job_posting.

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?

No when-to-use guidance, prerequisites, or alternatives are provided. An agent must infer that this is for a specific company's jobs rather than general search; search_jobs and check_job_posting are not mentioned.

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