Introduction
📦 @goodandready/dsh-moa
Mixture of Agents (MoA) Multi-Model Collaboration & Synthesis Engine for DeepSeek Harness
⚡ Overview & The Problem
Single-model AI generation often suffers from blind spots, single-perspective biases, hallucinated architectural choices, and inconsistent code quality on challenging engineering tasks. When prompted with ambiguous or complex specifications, a single model may make premature assumptions and produce monolithic, unvetted implementations.
@goodandready/dsh-moa brings the Mixture of Agents (MoA) architecture natively to DeepSeek Harness via the /moa slash command:
- Adaptive Clarification Questionnaire: For broad or underspecified prompts, advisor models formulate clarifying options and the judge synthesizes a structured 2–4 question questionnaire before generating code.
- Parallel Proposers Fan-Out & Workspace Isolation: Multiple independent models evaluate the prompt concurrently. Each candidate's proposed files are written to isolated disk sandboxes (
.moa/candidate-N/), avoiding cross-pollution. - Frontier Judge Evaluation & File Promotion: A flagship reasoning model critically benchmarks all proposals, selects the winning candidate via machine markers (
WINNER_CANDIDATE_INDEX: N), and promotes the winner's files directly into the project root directory. - Instant Live Canvas Previewing: When web applications or UI components are generated,
dsh-moaintegrates seamlessly with@goodandready/dsh-live-canvas, automatically spawning sandboxes for 1-click browser previewing. - Token-Saving Chat Summarization: Replaces massive code dumps in chat bubbles with compact file listings and clean architectural summaries.
- One-Shot Session Model Restoration: Executes cleanly as a one-shot turn modifier, automatically reverting back to the user's primary session model immediately after completion.

✨ Features & Capabilities
1. Slash Command (/moa) & Autocompletion
Integrated directly into the DeepSeek Harness composer via client input triggers. Typing /moa shows presets and instant autocompletion:
/moa build a real-time reactive dashboard with charts and websocket updates
Or target a specific named preset:
/moa:code-review audit the auth middleware and security boundaries
2. Adaptive Questionnaire Gate
When prompts are open-ended or lack architectural specifications (e.g. "build a calculator app"), advisor models detect ambiguities and formulate focused clarifying questions (e.g., UI style, persistence backend, framework choice) before generating code.
3. Parallel Fan-Out with Live Heartbeats
- Proposers query concurrently with live heartbeat progress badges (
⏳ [3s] Processing..., per-model completion status). - Bulky system prompts and tool schemas are cleanly stripped from advisor contexts, eliminating "missing tools" refusals and token bloat.
4. Disk-Level Candidate Isolation & Promotion
Unlike standard chat-only MoA, dsh-moa isolates file generation onto the filesystem:
- Each proposer generates files into
.moa/candidate-1/,.moa/candidate-2/, etc. - The Judge compares implementations and selects the optimal solution with
WINNER_CANDIDATE_INDEX: N. - The winner's files are promoted to the workspace root, and temporary candidate directories are pruned automatically.
5. Live Canvas 1-Click Preview
If web files (index.html, React/JSX components, Vue, CSS) are generated, dsh-moa communicates with @goodandready/dsh-live-canvas via its REST endpoint to instantiate a live preview container with 1-click instant access.
6. Native Settings Card & Presets
Configure your models in Settings → Plugins → Mixture of Agents:
- Set custom Proposer models (e.g., fast generative models for diverse ideas).
- Set the Aggregator / Judge model (e.g., deep reasoning models for rigorous critique).
- Configure named presets (
default,code-review,deep-reasoning).
📦 Installation
Install into your DeepSeek Harness web profile:
dsh plugin --profile web add @goodandready/dsh-moa
Restart your DeepSeek Harness instance and refresh the browser.
