Council of Experts — Multi-Model Validation
When to Auto-Trigger
Plans (auto_validate_plans)
When you write a plan to ~/.claude/plans/, automatically validate it:
~/bin/validate-plan --threshold 2 ~/.claude/plans/<plan-file>.md
- 2+ of 3 approve → execute immediately
- 1 of 3 → surface reviewer feedback to user before proceeding
- 0 of 3 → revise plan, re-validate
Architecture Decisions (auto_review_architecture)
When making architectural changes (new services, API redesigns, database schema changes), run:
~/bin/review --all "Review this architecture: <summary>"
PR Review (auto_review_prs)
Before marking a PR as done, run:
~/bin/review --all --file <changed-files>
Configuration
Council behavior is configured in ~/.claude/council.yaml. The Maggy dashboard (Settings > Council) also manages this config.
Chief of the Council
chief: claude-fable-5 — Claude Fable 5 (Anthropic's most capable widely-released
model, GA 2026-06-09) leads every panel as the chief: it reviews first and casts
the deciding synthesis. Invoked via ~/bin/claude-fable-5. Override the chief in
~/.claude/council.yaml.
Reviewer Contexts
The chief leads each context, followed by the panel:
| Context | Default Reviewers | When |
|---|---|---|
plan | Claude Fable 5 (chief), DeepSeek Pro, Codex, Gemini Pro | Before executing any plan |
review | Claude Fable 5 (chief), DeepSeek Pro, Kimi | Code review, PR review |
architecture | Claude Fable 5 (chief), DeepSeek Pro, Gemini Pro, Grok | System design, schema changes |
Threshold Rules
The threshold setting controls how many approvals are needed:
threshold: 2with 3 reviewers → need 2/3 to auto-execute- Clamped to [1, reviewer_count] — can't be 0 or exceed available reviewers
Model Inventory
All 13 tiers are listed in ~/.claude/council.yaml under models:. Each has:
id— unique identifiercmd— CLI command to invoke (null for Claude models, which are the host)tier— routing priority (0=cheapest, 12=most capable)label— human-readable name
Use POST /api/models/health to verify all models are responding.
How This Skill is Used
This skill is loaded by Claude Code on session start. It provides the behavioral rules for when to invoke multi-model validation. The actual execution happens via ~/bin/validate-plan and ~/bin/review which are already installed.
Do not skip council validation for CLAUDE-tier tasks. The whole point is that architecture and security decisions get independent verification before execution.
