claude-brainstorm-multiagent

Multi-agent ideation skill for Claude Code that fights LLM conformity through structural diversity — morphological decomposition, Quality-Diversity (MAP-Elites), explicit adversaries, and Pareto convergence — with a live force-graph dashboard that shows ideas being born, merged, critiqued, promoted, and bifurcated in real time.

Why this exists

Default LLM brainstorming converges to "average ideas" because:

• Post-RLHF mode collapse pushes outputs toward typical responses
• Multiple agents from the same base model amplify each other ("artificial hivemind", arXiv 2510.22954)
• Scalar scoring (ICE/RICE sums) hides trade-offs and rewards mediocrity

This plugin attacks each failure mode explicitly:

Failure mode	Counter-mechanism
Mode collapse	Verbalized sampling + min-p + cycling operators
Persona homogenization	Interview-grounded personas with cosine < 0.7
Convergence to mean	MAP-Elites archive (best per region, not best overall)
Premature consensus	Devil's-advocate + minority-voice critics every round
Judge bias	Rotated LLM judges in Elo tournament
Stagnation	Boden transformational rewriting of morphological axes
Hidden trade-offs	Pareto front over (novelty × feasibility × impact)

Method

A Double Diamond pipeline with Co-Scientist-style inner loop:

Phase 0  Socratic clarify          (1 agent)
Phase 1  Morphological decompose   (1 agent)      → defines the design space
Phase 2  Persona forge             (1 agent)      → N orthogonal personas
Phase 3  Ideation rounds (loop R rounds):
   3a    Divergent generation      (N parallel agents, cycling operators)
   3b    Embed + archive           (MAP-Elites placement)
   3c    Cluster + KJ              (HDBSCAN)
   3d    Adversarial critique      (Black Hat + Minority Voice)
   3e    Evolution                 (crossover, mutation, Boden transformation)
   3f    Tournament                (Elo with rotated judges)
Phase 4  Pareto front extraction
Phase 5  Meta-review + design docs

Operators that the divergent agents cycle through:

• SCAMPER (7 mutation types)
• Lateral PO (provocations)
• Random stimuli (Wikipedia / Oblique Strategies cards)
• Remote analogy (cross-domain, biomimicry)
• Worst-possible-idea + inversion
• Crazy 8s (8 quick ideas, no category overlap)
• Verbalized sampling (distribution with probabilities)
• Cell sampling (forced into under-explored MAP-Elites cells)

Intensity tiers

Tier	Time	Personas (N)	Rounds (R)	Archive	Tournament
instant	< 1 min	1	1	off	top-3
quick	5–10 min	3	2	5×5	top-5
standard	~1 h	6	5	8×8	Elo 30
deep	several h	8	12	10×10	Elo 100 + Pareto
marathon	1 day	12	30	12×12 + Boden	Elo 300 + adversarial
epic	several d	16	100+	16×16 + transforms every 20	Elo 1000

Installation

1. Install the plugin

From a marketplace (recommended):

/plugin marketplace add giordanorec/claude-brainstorm-multiagent
/plugin install claude-brainstorm-multiagent

Or directly from a local copy:

/plugin install file://path/to/plugin

2. Requirements

• Claude Code v2.1.172 or later
• Python 3.10+ available on PATH (the MCP server uses uvx; install via pip install uv if needed)
• For the dashboard: a modern browser. The launcher uses python -m http.server (already covered if you have Python).

3. First run

/brainstorm standard

then enter your topic when prompted, e.g.:

"New directions for renewable energy storage at residential scale."

The skill creates a run directory under runs/<timestamp>-<slug>/ and prints a URL like http://localhost:8765/dashboard.html — open it to see ideas being generated live.

Dashboard

Single-file HTML using force-graph (Vasco Asturiano) + ECharts via CDN. No build step.

Panels:

• Center: force-directed graph of ideas. Node size = Elo, color = cluster, glow = recent activity, particles = lineage flow.
• Right top: Agents activity feed — "div_3 is applying SCAMPER:Combine to i_0042".
• Right middle: Top-5 ideas (sentence each).
• Right bottom: Coverage gauge + structural-gap suggestions.
• Footer: timeline of round events.
• Drawers: semantic UMAP, parallel coordinates, MAP-Elites coverage heatmap, lineage tree.

Animations:

• idea_created — flash + grow
• idea_merged — convergent particles
• idea_bifurcated — radial burst
• idea_promoted — golden glow
• idea_critiqued — pulsing ring in critic's color
• Old ideas decay to ghost opacity but reappear when cited

Distribution

The plugin is self-contained. To share:
