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

With no annotations, the description carries full behavioral load and does so well: it discloses the validation step, the returned summary/consent line/token, the mandatory email click before any provider sees the enquiry, and the 'up to three providers' disclosure scope. It stops short of stating failure modes, what happens if consent=false, or whether a validated step-1 call can be re-called.

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?

Front-loads the crucial framing ('NOT a purchase') before the two-step procedure, which is the right ordering for an agent. Slightly long because the consent paragraph is reproduced nearly verbatim from the schema, but every remaining sentence carries procedural weight.

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?

For a two-phase, consent-gated submission tool with a nested answers object and no output schema, the description covers the sequence, the token, the consent meaning, and the email-verification gate. It could add what step-1 returns structurally or the consequences of an aborted step 2, but an agent can invoke it correctly from this text.

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 100% and the consent parameter already embeds the full consent text, so the description largely mirrors what the schema provides. It does add the key insight that 'answers' must be keyed by enquiry_fields keys and that 'confirmation' comes from step 1, but otherwise the schema does the heavy lifting.

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 ('Submits an enquiry to Malta Work Permit Checker') and immediately negates the wrong reading ('NOT a purchase, NOT a guaranteed quote'). It is clearly distinguishable from siblings like enquiry_describe and enquiry_fields, which the description names as the source of field keys.

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 lays out the two-step when/when-not flow: Step 1 validates and returns a summary/token; Step 2 only fires 'if the person agrees'. It also names the sibling enquiry_fields as the source of answer keys, so an agent knows the prerequisite call.

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