contacts_research

Read-onlyIdempotent

Research a person before outreach: returns a synthesized profile (current role, company, location, career history, education, LinkedIn/social URLs) plus a candidates array for disambiguating namesakes. Use to personalize a first touch or brief before a meeting. Does NOT return contact channels (email/phone/telegram) — use contacts.discover to add a reachable channel, or the LinkedIn URL from the result for a connection request.

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

Input Schema

NameRequiredDescriptionDefault
queryYesWho to research: full name plus any disambiguating context you have (company, role, location), e.g. '[full name], founder of [company]'.
in_workspaceNoRun this one call in this workspace id instead of the session's. Nothing is stored; other sessions are not affected.

TDQS

A4.5/5.0
Behavior4/5

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

Annotations already declare the safe-read profile (readOnly, idempotent, openWorld, non-destructive), so the bar is lower; the description adds real value by disclosing the return shape and the namesake-disambiguation behavior via the candidates array. It stops short of mentioning cost, latency, or caching behavior for an open-world lookup, keeping it from 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.

Conciseness5/5

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

Three clauses, zero waste: purpose and return shape front-loaded, then the negative boundary and its alternative. Every sentence earns its place.

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?

No output schema exists, so the description carries the return-value burden and does so by enumerating the profile fields and the candidates array. Combined with the explicit boundary about contact channels and the usage triggers, an agent has everything needed to call it correctly.

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 100%, so the schema already documents both query and in_workspace with examples. The description adds no syntactic or formatting detail beyond what the schema provides, so 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 (research) and resource (a person) and enumerates the synthesized fields returned (role, company, location, career history, education, social URLs) plus the disambiguation candidates array. It also differentiates itself from siblings by explicitly naming contacts.discover and contrasting the return shape.

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?

Gives explicit when-to-use triggers (before outreach, to personalize a first touch or brief before a meeting) and an explicit when-not (does not return contact channels), routing the agent to contacts.discover for a reachable channel. Nothing is left to inference.

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