⚡ 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. - 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.
- Dynamic Model Pricing Catalog & Token Estimation: Real-time rate resolution for 300+ models fetched automatically in the background from OpenRouter's public catalog (cached locally in
~/.dsh/storages/dsh-moa-catalog.jsonfor 24h), plus support for direct vendor rates and custompricesoverrides insettings.yaml. - Refinement Mode (Incremental Edits): Automatically detects existing codebase context to generate precise delta modifications instead of destructive full-file rewrites.
- Fast Mode & Custom Judge Criteria: Ultra-fast single-model preset for quick tasks and customizable evaluation guidelines for the judge.
- Run History & Win-Rate Leaderboard: Persistent logging of every run kind (synthesis, fast mode, questionnaire) with built-in REST endpoints (
/dsh-moa/history,/dsh-moa/leaderboard,/dsh-moa/runs/<id>). - Live Canvas 1-Click Preview (optional): when the
@goodandready/dsh-live-canvasplugin is installed in the same profile, the promoted HTML is pushed to its sandbox and the MoA answer carries a one-click preview link; without it the step is skipped silently.

✨ 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
The flag form is equivalent:
/moa --preset=deep-reasoning solve this math problem step by step
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. 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,fast,deep-reasoning), judge criteria and temperatures. - Enable or disable MoA and see the real host status chip; the telemetry grid shows total runs and average run cost.
7. Candidate Diff Viewer
Inspect line-by-line differences between candidate proposals and the curator's synthesized deliverable directly in the UI. Features file selection, delta line highlights (added, removed, same), and unified diff rendering via a zero-dependency in-memory LCS algorithm.
8. Pre-Promotion Git Checkpoints (dsh-time-machine)
Before promoting any winning candidate files over the workspace root, dsh-moa invokes the local dsh-time-machine service to create a shadow Git checkpoint (moa-pre-promotion: candidate-N). If dsh-time-machine is absent or unreachable, file promotion proceeds seamlessly via best-effort fallback.
6. Live Canvas 1-Click Preview (optional)
If @goodandready/dsh-live-canvas is installed in the same profile, dsh-moa pushes the promoted HTML file to the Live Canvas REST contract (POST /dsh-live-canvas/api/preview, served by the same harness webServer) and appends a one-click preview link (/dsh-live-canvas/sandbox/<id>) to the answer. Without the plugin the step is skipped silently — no errors in the log, no dead links.
📦 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.
⚡ 10 Specialized Built-in Presets & Candidate Personas
v0.2.13 introduces 10 ready-to-use presets engineered for real-world software workflows:
| Preset Name | Purpose | Default Aggregator | Peer Critique | Blind Eval |
|---|---|---|---|---|
default | Balanced multi-model generation | codex:gpt-5.6-sol | Optional | Off |
code-review | Thorough peer review & vulnerability detection | codex:gpt-5.6-sol | On | On |
fast-audit | Ultra-fast single-model audit (Fast Mode) | codex:gpt-5.6-sol | Off | Off |
deep-architect | Distributed systems & complex architectures | codex:gpt-5.6-sol | On | Off |
bug-hunter | Root cause discovery & adversarial edge cases | codex:gpt-5.6-sol | On | Off |
refactor-cleanup | Dead-code pruning & standard-library simplicity | codex:gpt-5.6-sol | Off | Off |
frontend-ui | High-fidelity responsive web interfaces | codex:gpt-5.6-sol | Off | Off |
security-audit | Zero-trust threat analysis & sanitization | codex:gpt-5.6-sol | On | On |
math-logic | Deterministic algorithmic proofs & math logic | codex:gpt-5.6-sol | On | Off |
creative-brainstorm | Divergent lateral thinking & ideation | codex:gpt-5.6-sol | Off | Off |
Candidate Personas (role_persona)
Assign archetypal engineering mentalities to individual candidate slots to ensure genuine perspective divergence:
minimalist(Ponytail Senior): standard library first, zero external dependencies, minimal moving parts.robustness: defensive coding, boundary validation, graceful fallback handling, idempotent operations.performance: algorithmic complexity minimization, memory efficiency, zero-copy operations.tester: test-driven methodology, high branch coverage, explicit assertion design.general: balanced standard engineering approach.
🤝 Consilium Round 2 (Peer Critique) & Syntax Auto-Fix Gate
- Consilium (Round 2): Enable
peer_critique_enabled: truein preset settings. Each candidate receives peer proposals and submits an improved, hardened iteration before judge evaluation. - Syntax Pre-Check Gate: In-memory JS/MJS and JSON syntax verification runs automatically on all candidate files. If a proposal contains syntax errors, it is flagged with
[⚠️ Syntax Warning]and the judge receives a strict mandate: if this candidate has superior design, auto-correct the syntax in the synthesized deliverable and award them the win. - User Candidate Override: Enable
allow_candidate_override: trueto preserve candidate sandboxes in.moa/candidate-N/. At any time, promote any candidate using/moa promote <runId> <candidateIndex>or the UI button.
