Public Company Contacts

extract_company_contacts

Read-only

Company contact lookup from a domain: published emails and LinkedIn, X and GitHub links from the home, about, contact, team and careers pages, deduplicated, plus MX, SPF and DMARC records. Not mailbox verification. Use when an agent needs public company contact data for outreach research. $0.01; nothing found is free.

`domain`	Yes	Bare public company domain whose published contact pages and DNS records should be inspected.

TDQS

A4.1/5.0

Behavior4/5

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

Annotations already declare readOnlyHint and openWorldHint, so safety is covered; the description adds genuinely new behavior: deduplication, the specific pages crawled, DNS record inclusion, and a pricing model ('$0.01; nothing found is free'). That cost/no-result rule is exactly the kind of detail an agent needs before spending on a call. It doesn't state rate limits or latency, keeping it short of a 5.

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

Conciseness4/5

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

The output inventory and crawl scope are front-loaded, followed by the exclusion, the use case, and pricing — a sensible priority order with no filler. The opening sentence is long and packs four clauses, which is dense but still parseable.

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

Completeness4/5

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

With an output schema available, the description doesn't need to describe return shape, and it covers scope, exclusions, and cost. For an open-world scraper, missing details are error/empty-result handling beyond the free-if-nothing-found note, and expected latency — minor for a two-parameter read tool.

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 coverage is 100%, including a clear definition of 'domain' as a bare public company domain and the optional 'context' field. The description adds nothing parameter-specific beyond implying the domain drives the page crawl, so the schema does all the work — the baseline 3 applies.

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?

States a specific verb and resource ('Company contact lookup from a domain') and enumerates exactly what comes back: published emails, LinkedIn/X/GitHub links, and MX/SPF/DMARC records. It also scopes the crawl to home, about, contact, team and careers pages, so the agent knows the boundary of the lookup without opening the schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

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

'Use when an agent needs public company contact data for outreach research' gives a clear triggering context, and 'Not mailbox verification' excludes a plausible misread. It stops short of naming an alternative tool from the sibling list (e.g. private_blind_lookup or company_footprint_check), so routing between siblings still requires inference.

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