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

With no annotations, the description carries the full burden of behavioral disclosure, but it only says 'V1 Jobs Multi'. It does not explain that this likely aggregates results across multiple sites, whether it performs network calls, or what side effects or limitations exist.

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?

The description is extremely short, but this is under-specification rather than conciseness. It front-loads nothing useful and every word ('V1', 'Jobs', 'Multi') is either a version marker or a restatement of the tool name.

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 tool with 5 undocumented parameters, no annotations, no output schema, and three siblings, the description is completely inadequate. An agent cannot determine what the tool does, what inputs mean, what it returns, or how it differs from jobs, jobs_indeed, and jobs_linkedin.

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 0%, so the description must compensate, but it provides no parameter information at all. The schema itself has bare names like 'query', 'sites', 'country', 'location', and 'resultsWanted' with no descriptions, leaving the agent to guess formats, defaults, and semantics.

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 'V1 Jobs Multi' is essentially a version label, not a statement of what the tool does. It names the resource ('jobs') and hints at multi-site aggregation, but there is no verb or behavior described, and it does not distinguish it from siblings like jobs, jobs_indeed, or jobs_linkedin.

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 guidance is provided about when to use this tool versus the sibling tools. The name suggests it searches multiple job sites, but the description never states this or gives conditions for choosing it over jobs_indeed or jobs_linkedin.

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