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

Beyond the readOnly/idempotent annotations, it discloses the two-step stock-lane behavior, the ~200-word script length, and the 100-second window. The 'random picks' wording sits slightly loosely with idempotentHint, but not enough to be a contradiction.

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 sentences, no filler: purpose first, then lane list, then the special stock workflow and reading constraint. Every sentence carries load.

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?

The main call flow and the stock special case are fully described, and with no output schema the script length/content is also given. The only gap is that non-stock lanes do not get similar treatment, though the opening sentence implies they return a read-off script.

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 coverage is 100%, so the baseline is 3; the description adds real value by explaining that symbol is optional and only stock-lane calls without it return the 10 picks to choose from. This clarifies how lane and symbol interact.

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: 'Generate the applicant's read-off script for a Voice Analyst lane', and enumerates the six lane values. It also names get_job_menu as the prerequisite, so it is clearly distinct from the sibling market-data tools.

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 an explicit workflow: call after get_job_menu, and for the stock lane call once without a symbol to get picks and again with the chosen symbol to get the script. It does not explicitly name when-not-to-use alternatives, but the lane list and two-phase instructions make the intended context clear.

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