Send outreach emails

exim__email__send

Destructive

Sends outreach emails to the companies in a collection. Without confirm it returns a preview only; with confirm it runs signature, sender-domain and OFAC SDN checks and sends.

Input Schema

Name	Required	Description
`ccMe`	No	CC the sender on each outbound
`brief`	Yes	Outreach brief — what to mention, tone, ask
`dryRun`	No	Explicit preview alias. Equivalent to omitting confirm — generates drafts without sending.
`confirm`	No	Required to actually flush emails. WITHOUT confirm this is always a safe preview (no send), even without dryRun. The pre-send sanity guard runs only when confirm is set.
`profile`	No	Saved ideal-profile name; when set, each draft references the observed fit (matched attributes) to personalize the opening
`regenerate`	No	Redraft fresh copy on send instead of flushing the exact drafts produced by the last `email draft` preview. Default false — send flushes the approved preview so sent copy matches what was reviewed.
`senderName`	Yes	Sender display name
`senderEmail`	No	From email (must be operator-owned domain)
`collectionId`	Yes	Collection name or id
`trackingEnabled`	No	Enable open/click tracking
`includeLowConfidence`	No	Include low-confidence recipient emails (role aliases info@/sales@, no-reply, single-letter local, image-filename addresses). Default false — these are auto-pruned and counted in stats.autoPruned.

Output Schema

Name	Required	Description	Default
`data`	Yes
`stats`	No
`_debug`	No
`summary`	Yes
`warnings`	No
`nextActions`	Yes
`correlationId`	No

TDQS

A3.8/5.0

Behavior4/5

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

Annotations already declare destructiveHint=true, openWorldHint=true and non-idempotent, so the safety bar is lower. The description still adds real value beyond that: the confirm gating on preview vs. actual send and the specific pre-send checks (signature, sender-domain, OFAC SDN) are not in the annotations, giving the agent concrete behavioral context.

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?

Two sentences, no filler, and the critical decision variable (confirm) is stated up front in the first sentence. Every clause earns its place by conveying the preview/send distinction.

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?

An output schema exists, so return values need not be explained, and annotations carry the safety profile. The description covers the destructive-send gating and the compliance checks, leaving only minor gaps such as volume limits or what happens to already-approved drafts — not essential for correct invocation.

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 every parameter including confirm, dryRun, regenerate and includeLowConfidence. The description reinforces the confirm semantics but adds no syntax or format 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.

Purpose4/5

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

The description names a specific verb and resource with scope: 'Sends outreach emails to the companies in a collection.' It clearly distinguishes the two modes (preview vs. real send), but it never explicitly references the sibling exim__email__draft, which is the natural alternative for the drafting-only case, so sibling differentiation is only partial.

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

Usage Guidelines3/5

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

It gives useful conditional guidance ('without confirm ... preview only; with confirm ... sends') that helps an agent decide the mode. However, it never names exim__email__draft as the tool to reach for when the agent only wants drafts, nor does it state prerequisites such as needing an existing collection or an operator-owned sender domain, so usage is implied rather than explicit.

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