consensus-guard-core

consensus-guard-core is the common policy engine behind the Consensus guard ecosystem.

What this skill/package provides

• unified hard-block taxonomy
• deterministic aggregateVotes() policy function
• deterministic reputation update rules with clamping
• idempotency key generation for retry-safe execution
• strict-schema unknown-field rejection helpers
• indexed board read helpers for scalable artifact lookup

Why this matters

Without a shared core, every guard drifts into incompatible policy logic. This package keeps behavior consistent, replayable, and comparable across domains.

Ecosystem role

consensus-guard-core is consumed by publish/support/merge/action guards and should be treated as policy infrastructure, not an end-user workflow skill.

Benefits for LLM orchestration

• lower integration drift
• consistent decision semantics across workflows
• easier auditing and cross-skill analytics

Runtime, credentials, and network behavior

• runtime binaries: node, tsx
• network calls: none in this package's core decision/path helpers
• credentials: none required by this package
• environment config read by this package: CONSENSUS_STATE_FILE, CONSENSUS_STATE_ROOT (for board/state path resolution)
• filesystem writes: board/state artifacts under the configured consensus state path when callers use write helpers (for example writeArtifact)

Dependency trust model

• consensus-guard-core is a first-party consensus package
• versions are semver-pinned in package.json for reproducible installs
• this skill does not request host-wide privileges and does not mutate other skills
• note: dependency trees should be audited separately by consumers for transitive packages

Install

npm i consensus-guard-core

Quick start

npm test

Import contract

Use the package root import (stable public API):

import { aggregateVotes, writeArtifact, resolveStatePath } from 'consensus-guard-core';

Do not import internal paths like consensus-guard-core/src/index.mjs in dependent skills.

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() is primitives-only and delegates to a caller-provided handler. It does not perform persona generation or model/provider calls.
