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

Annotations say readOnlyHint=false, openWorldHint=true, idempotentHint=false, destructiveHint=false. The description usefully adds 'Sends nothing' (no transmission to employers) and points to `say` for the summary. That is real value beyond annotations. However, it does not explain the non-idempotent nature or what openWorld fetching occurs, leaving a gap given the write-ish annotation profile.

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?

Four short sentences, front-loaded with the core action and scope. Terse and largely waste-free; the mention of `say` could be clearer but does not pad the text.

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 no output schema, zero parameter documentation, and a batch mutation-adjacent operation with openWorld behavior, the description omits too much: parameter formats, behavior at the 10-job limit, and what 'prepare' actually creates. For a 2-param tool with these annotations, this is under-specified.

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 document job_ids and cv_variant, yet it mentions neither. It only says 'up to 10 jobs' without mapping that limit to job_ids, and cv_variant is entirely undocumented.

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 action (prepare applications) and scope (up to 10 jobs), and explicitly frames it as the batch version of prepare_application. That framing against the sibling is the clearest signal of purpose. Could be sharper about what 'prepare' produces internally for the agent.

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 equivalent single-job tool (prepare_application), implying you use this when handling multiple jobs. But it never states when NOT to use it or the 10-job boundary behavior — e.g., whether it truncates or fails on more than 10 ids.

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