consensus-send-email-guard

consensus-send-email-guard is a production-style outbound communication guardrail.

What this skill does

• evaluates an email draft with a persona panel
• aggregates votes by reputation (weighted approval policy)
• enforces hard-block categories (sensitive data, legal/medical certainty, disallowed guarantees)
• returns final decision: APPROVE | BLOCK | REWRITE
• writes decision artifacts to board state

Why this matters

Email is high-impact and irreversible once sent. This skill reduces hallucinated promises and policy-violating claims before external side effects occur.

Ecosystem role

Stack position:

consensus-tools -> consensus-interact pattern -> persona_set -> send-email-guard

It converts raw generation into governed action with auditability.

Governance and learning

• strict JSON contracts for automation pipelines
• idempotent retries to prevent duplicate reputation mutation
• reputation updates calibrate evaluator influence over time

Use cases

• customer-facing outbound messaging
• partner/legal-sensitive communications
• automated campaign quality gates

Runtime, credentials, and network behavior

• runtime binaries: node, tsx
• network calls: none in guard decision logic
• environment config read by this package: CONSENSUS_STATE_FILE, CONSENSUS_STATE_ROOT
• filesystem writes: board/state artifacts under the configured consensus state path

Dependency trust model

• consensus-guard-core is the first-party consensus package used in guard execution
• versions are semver-pinned in package.json for reproducible installs
• this skill does not request host-wide privileges and does not mutate other skills

Install

npm i consensus-send-email-guard

Quick start

node --import tsx run.js --input ./examples/email-input.json

Tool-call integration

This skill is wired to the consensus-interact contract boundary (via shared consensus-guard-core wrappers where applicable):

• readBoardPolicy
• getLatestPersonaSet / getPersonaSet
• writeArtifact / writeDecision
• idempotent decision lookup

This keeps board orchestration standardized across skills.

Invoke Contract

This skill exposes a canonical entrypoint:

• invoke(input, opts?) -> Promise\x3COutputJson | ErrorJson>

invoke() starts the guard flow and executes deterministic policy evaluation with board operations via shared guard-core wrappers.

external_agent mode

Guards support two modes:

• mode="external_agent": caller supplies external_votes[] from agents/humans/models for deterministic aggregation.
• mode="persona": requires an existing persona_set_id; guard will not generate persona sets internally.
