name: council description: 'Run multi-judge consensus.'

$council — Multi-Model Consensus Council (Codex Native)

Spawn parallel judges with different perspectives via spawn_agent, consolidate into consensus.

Quick Start

$council --quick validate recent                               # fast inline check
$council validate this plan                                    # validation (2 judges)
$council brainstorm caching approaches                         # brainstorm
$council --deep validate the implementation                    # 3 judges
$council --preset=security-audit validate the auth system      # preset personas
$council --deep --mixed --preset=leadership-quartet validate product thesis

Modes

Note: --debate (multi-round adversarial) requires agent messaging. Use spawn_agent plus send_input for one-off follow-up only; do not rely on debate-style rounds.

Note: --mixed is strict. Pre-flight codex and codex --version before spawning any judges; if Codex CLI is missing or not runnable, hard-error and tell the operator to install/fix Codex CLI or drop --mixed. Never silently convert --mixed into runtime-native-only judging.

Note: --profile=<name> follows the shared model-profile contract: balanced, budget, fast, inherit, quality, thorough. See references/model-profiles.md.

Task Types

Execution Flow

Phase 1: Build Packet

1. Determine task type from user prompt
2. Identify target (files, diffs, plan, code)
3. Read relevant context files
4. Select perspectives (or use preset)

Phase 1a: Spawn Judges

Use one spawn_agent call per judge. Include the same context packet in each prompt and assign a distinct perspective.

Mixed-mode pairing (--mixed only): For --mixed, build the perspective list once. For each perspective, spawn ONE spawn_agent call AND ONE codex exec process with the SAME perspective string, SAME packet, SAME prompt — only the vendor differs. The pair holds perspective constant and varies only the vendor, enabling head-to-head cross-vendor comparison per perspective. Do NOT split perspectives across vendors (e.g., do NOT give Claude judges perspectives 1-3 and Codex judges perspectives 4-6). Total judges = 2 × len(perspectives); default = 6.

spawn_agent(message="You are judge-1.

Perspective: correctness

Task: validate the following target.
Target files: ...
Context: ...

Write your full analysis to .agents/council/judge-1.md and your verdict to the final paragraph.")

spawn_agent(message="You are judge-2.

Perspective: completeness

Task: validate the following target.
Target files: ...
Context: ...

Write your full analysis to .agents/council/judge-2.md and your verdict to the final paragraph.")

With --mixed, spawn the runtime-native judges above plus 3 Codex CLI judges. Codex CLI judges write under .agents/council/codex-{N}.json when --output-schema is supported, or .agents/council/codex-{N}.md as an output-format fallback only. See references/cli-spawning.md for the strict pre-flight and command shape.

Step 1b: Load Project Reviewer Config

Check for project-level reviewer configuration before spawning judges:

REVIEWER_CONFIG=".agents/reviewer-config.md"
if [ -f "$REVIEWER_CONFIG" ]; then
    # Parse YAML frontmatter for reviewer list
    # Use reviewers/plan_reviewers/skip_reviewers to select judge perspectives
fi

If reviewer-config.md exists:

• Use reviewers list to select which judge perspectives to spawn
• Use plan_reviewers for plan validation specifically
• Use skip_reviewers to exclude perspectives even if preset includes them
• Pass markdown body as additional context to all judges

If no config exists, use defaults (current behavior unchanged).

For schema details and an example, see references/reviewer-config-example.md.

Phase 1b: Wait for Judges

wait_agent(targets=["agent-id-1", "agent-id-2"])

If a judge needs follow-up, use send_input on that agent. If a judge stalls, close_agent it and proceed with the remaining responses.

Phase 2: Consolidation (Lead — Inline)

The lead reads each judge's output file and synthesizes:

1. Read each .agents/council/judge-*.md file
2. Compute consensus verdict:
   • PASS: All judges PASS (or majority PASS, none FAIL)
   • WARN: Any judge WARN, none FAIL
   • FAIL: Any judge FAIL
   • Core rules: All PASS -> PASS; Any FAIL -> FAIL; Mixed PASS/WARN -> WARN; cross-vendor disagreement -> DISAGREE.
3. Identify shared findings across judges
4. Surface disagreements with attribution
5. Generate final report

Phase 3: Write Report

Save to .agents/council/YYYY-MM-DD-<type>-<target>.md:

# Council Report: <type> <target>

**Consensus:** PASS/WARN/FAIL
**Judges:** N responded / N spawned
**Date:** YYYY-MM-DD

## Shared Findings
- Finding 1 (judges 1, 2)
- Finding 2 (judges 1, 3)

## Disagreements
- Judge 1 says X, Judge 2 says Y

## Recommendations
1. ...
2. ...

## Individual Verdicts
| Judge | Perspective | Verdict | Confidence | Findings |
|-------|-------------|---------|------------|----------|
| judge-1 | correctness | PASS | high | 3 |
| judge-2 | completeness | WARN | medium | 5 |

Presets

Use: $council --preset=security-audit validate the auth system Use: $council --deep --mixed --preset=leadership-quartet validate product thesis

Graceful Degradation

Context Budget Rule

Judges write ALL analysis to output files. Results to the lead contain ONLY minimal signals. This prevents N judges from flooding the lead's context.

Standards Integration

If $standards is available and the target includes code files, load applicable language standards and include them in each judge prompt.

First-Pass Rigor Gate (validate mode)

When validating plans/specs, judges must check:

1. Mutation + ack sequence is explicit and non-contradictory
2. Consume-at-most-once path is crash-safe
3. Status/precedence behavior has field-level truth table
4. Conformance includes boundary failpoint tests

Missing gate item → minimum WARN. Critical unverifiable invariant → FAIL.
