Verify an email

leads_get_email_status
Read-onlyIdempotent

Whether an email address the user already has will deliver.

Use when: "is jane@acme.com still valid", cleaning a list before a send, checking a shortlist from leads_get_domain_emails. Not for: finding an address, use leads_get_email or leads_get_domain_emails. Returns: Record. email, status (valid | invalid | accept_all | unknown; accept_all means the server takes anything, so the address is unproven), result (deliverable | undeliverable | risky | unknown), score (0 to 100), mx_records, mail_provider (who runs the mail servers: google, microsoft, or a filter such as mimecast). disposable, webmail and smtp_check are null: the verifier does not report them, so judge free-mail and throwaway domains by the domain. Cost: 1 credit. Cached 30 days. Example: {"email": "jane@acme.com"}

TDQS

A4.7/5.0
Behavior5/5

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

Beyond the annotations (which already cover readOnly/idempotent/non-destructive), it discloses cost (1 credit), a 30-day cache, and interpretive caveats that matter operationally: accept_all means the server takes anything so the address is unproven, and disposable/webmail/smtp_check come back null so free-mail must be judged by the domain. Those are real behavioral facts an agent could not infer from the structured fields.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Labeled sections (Use when / Not for / Returns / Cost / Example) front-load purpose and routing, and every sentence carries a decision-relevant fact. The single-argument example is short and immediately actionable.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a four-parameter, read-only lookup with an output schema and full annotations, nothing an agent needs to call it correctly is missing: routing, cost, caching, result-code interpretation, and a call example are all present. The Returns narrative slightly overlaps the output schema but adds interpretation the schema cannot.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 75%, with dry_run, provider and max_credits documented in the schema itself, so the baseline is near 3. The description adds no guidance on dry_run, provider selection, or max_credits budgeting, though the cost line implicitly motivates budget control. Adequate but with a clear gap.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

"Whether an email address the user already has will deliver" gives a specific verb (verify deliverability) and a specific resource (an email address the user already possesses). The phrasing itself carves out the boundary with leads_get_email and leads_get_domain_emails, which find addresses rather than test them, so an agent can distinguish the siblings 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.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It supplies concrete triggering scenarios ("is jane@acme.com still valid", cleaning a list before a send, checking a shortlist from leads_get_domain_emails) and an explicit exclusion: "Not for: finding an address, use leads_get_email or leads_get_domain_emails." Both the when and the when-not are stated with the named alternative.

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