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

Annotations already establish this is a safe, idempotent, read-only, closed-world operation, so the bar is lower. The description adds genuinely useful behavioral context: it returns ordered steps, a run count, the daily allowance, and a matching plan with price and link — output behavior the annotations do not convey.

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 core action is front-loaded in the first clause, followed by the outputs and then the usage trigger. It is somewhat run-on with a long mid-sentence list, but every clause carries distinct information and nothing is redundant.

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, the description correctly explains the return values (steps, run count, allowance, plan with price/link), and the single required parameter is fully covered by the schema. It is complete enough for correct invocation; only the absence of an explicit single-task alternative keeps it from a 5.

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?

There is a single parameter at 100% schema coverage, so the schema already documents that 'job' is the whole job in the user's words. The description adds a concrete example ('merge these scans, compress to 4 MB for IRCC and add a password') but no additional format or syntax constraints beyond the schema. 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?

States a specific verb and resource ('turn a PDF job with several steps ... into ordered steps, each with the DocuGrip page that does it') plus the secondary outputs (run count, allowance, plan fit). This clearly distinguishes it from sibling lookup tools like find_pdf_tool, get_pdf_tool, and get_plans.

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?

Explicitly states the triggering conditions: 'when the user describes more than one thing to do to their files, a batch of files, or work they do regularly.' That is a clear when-to-use rule, though it never names the alternative (find_pdf_tool) for the single-step case, leaving that inference to the agent.

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