Three independent agents must vote PASS unanimously — no 2/3 approvals.

Three independent agents vote on every phase gate. All three must return PASS — no 2/3 majority, no shortcuts, no skipped reviews.

AGENT SPAWNS STUDIED

REVIEWERS PER GATE

100%

UNANIMOUS REQUIRED

P2 BUG FOUND

“A code review you can trust because nobody writes and reviews their own work.”

Three specialized agents — Lead (architecture), Alpha (correctness), Bravo (edge cases) — each start fresh and independently verify phase-gate work. All three must return PASS for the gate to open. 2/3 does not pass.

Built from catching a P2 streaming bug that single-agent review explicitly approved. Fix cycles re-validate against ALL agents, not just the failing one. Ships as a Claude Code plugin (5 slash commands, 3 agents, 1 skill, 1 hook) or as a pipx CLI for non-interactive CI — same prompts, same evidence schema.

01. ARCHITECTURE

How it's built

MODULE 00

Lead

Architecture and consistency specialist. Validates cross-component coherence, pattern compliance, and regression detection at phase boundaries.

MODULE 01

Alpha

Code and logic specialist. Reads implementation line-by-line for incorrect accumulation patterns, off-by-one errors, and API contract violations.

MODULE 02

Bravo

Systems and functional specialist. Exercises the running system, verifies real behavior under real conditions, and catches regressions. The only role with Bash.

02. FEATURES

Unanimous Gates

Lead + Alpha + Bravo all vote PASS or the phase doesn't ship. Any FAIL triggers a full re-validation on the next pass.

Independent Starts

Each agent begins with a fresh context. No shared findings leak between reviewers until the vote is cast.

Re-validate All After Fixes

A targeted fix does not get a narrow re-review. All three agents re-run, guarding against regression on previously-passing criteria.

Native Claude Code Integration

`/consensus-run`, `/consensus-validate`, `/consensus-roles`, `/consensus-report`, `/consensus-show-config` as first-class slash commands. Task-tool agents inherit your auth. State resumable via `.consensus/state.json` with `schema_version:1` forward-compat.

03. QUICK START

// install

# install as a Claude Code plugin
claude plugin marketplace add krzemienski/multi-agent-consensus
claude plugin install multi-agent-consensus@multi-agent-consensus

# cheap pre-flight canary (~3 completions) before full pipeline
/consensus-validate --phase audit --target ./my-project

# full pipeline: audit + verify with fix-cycle support
/consensus-run --target ./my-project --phases audit,verify

# resume an interrupted run from the last completed gate
/consensus-run --target ./my-project --phases audit,verify --resume

04. INSTALL

01claude plugin marketplace add krzemienski/multi-agent-consensus
02claude plugin install multi-agent-consensus@multi-agent-consensus
03Run /consensus-validate --phase audit --target <repo> as a 3-completion canary
04Run /consensus-run --target <repo> --phases audit,verify for the full pipeline (~24-30 completions)
05Alternative (pipx / CI): pipx install git+https://github.com/krzemienski/multi-agent-consensus.git
