B3.1/5.0
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare idempotentHint=true and destructiveHint=true, and the description adds no further behavioral context. It does not explain what 'mark as applied' implies (e.g., job status change, career history update) or any side effects beyond the annotation hints. The description contributes nothing beyond the structured metadata.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, front-loaded sentence with a clear verb and object. It contains no fluff or redundancy, making it appropriately concise for a simple tool with a single parameter. Every word earns its place.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity (one parameter, output schema present) and the annotations covering safety (idempotent, destructive), the description is minimally sufficient. However, it lacks any note about when to invoke this action, prerelease conditions (e.g., job must exist), or consequences beyond the annotation hints. It is complete enough for a straightforward mutation but misses a chance to add valuable context.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema covers 100% of the parameters, providing a description for job_id ('Job id'). The tool description does not add any additional meaning to the parameter; it relies entirely on the schema, which is complete for this single parameter. Baseline 3 is appropriate because the schema already documents the parameter fully.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description 'Mark a job as applied' clearly identifies the action (mark applied) and the resource (job). It is unambiguous, but it does not explicitly differentiate from siblings like jobs.update or signals.list_applied_jobs, relying on the verb 'mark applied' to convey uniqueness.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus alternatives. It does not mention that this tool should be used after submitting an application, nor does it contrast with jobs.update or other job-state-changing tools. The agent is left to infer usage from the name alone.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
