consensus-agent-action-guard

consensus-agent-action-guard is the final safety gate before autonomous action execution.

What this skill does

• evaluates proposed agent actions (risk, irreversibility, side effects)
• applies hard-block and weighted consensus logic
• returns one of: ALLOW | BLOCK | REQUIRE_REWRITE
• emits required follow-up actions (e.g., human confirmation)
• writes decision and persona updates to board artifacts

Why this matters

Most catastrophic automation failures happen at execution time. This skill inserts explicit governance before side effects.

Ecosystem role

Built on the same consensus stack as communication and merge guards, giving one policy language across agent operations.

Typical usage

• gating destructive operations
• controlling external messaging/posting actions
• requiring human confirmation for irreversible high-risk tasks

Runtime, credentials, and network behavior

• runtime binaries: node, tsx
• network calls: none in the guard decision path itself
• 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

Quick start

node --import tsx run.js --input ./examples/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<OutputJson | 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.
