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

No annotations are provided, so the description carries the full burden and does so: it discloses that step 1 only validates and returns a summary/consent line/token, that step 2 commits the enquiry, that an email verification gate stands between submission and provider visibility, and what consent actually means. This is far more than the schema reveals.

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 critical caveat (not a purchase, not a quote) is front-loaded and the two steps read in order. It is a single dense paragraph and the German consent sentence is repeated verbatim from the schema, a minor redundancy, but almost every clause earns its place.

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?

There is no output schema, so the description must cover return values — and it does, naming the summary, the consent line and the confirmation token returned by step 1. For a stateful, human-in-the-loop write tool, nothing an agent needs to drive both calls correctly is missing.

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, but the description adds real meaning the schema cannot: it explains that answers must be keyed by field key from enquiry_fields, and that confirmation is only supplied on the second call after human approval. It stops short of describing value formats, but the two-step semantics are the important addition.

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+resource ('Submits an enquiry to Rechner HQ') and immediately negates what it is not ('NOT a purchase, NOT a guaranteed quote'). It also names the sibling dependency enquiry_fields for the answer keys, so an agent can place it among the dataset_* / enquiry_* tools without opening a schema.

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 explicit sequencing: Step 1 with answers + consent=true, show the summary; Step 2 only if the person agrees, with the same answers plus the confirmation token. It also states the gating condition for downstream visibility (the person must click an emailed link before any provider sees it).

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