dMatrix decision-capture Skill for Chat-to-Matrix — structured decision matrices from natural conversation
Bring dMatrix decision-capture to your favorite AI assistant. dMatrix notices when you're weighing alternatives, evaluating trade-offs, or making a decision — and offers to capture it as a structured, auditable decision matrix.
| Assistant | Guide | One-step setup? |
|---|---|---|
| Claude (Code, Desktop, claude.ai) | claude/README.md | ✅ Claude Code plugin |
| OpenAI (ChatGPT & Codex) | openai/README.md | — two quick steps |
| Google (Antigravity CLI) | google/README.md | ✅ Antigravity plugin |
Both parts are required. With only the behavior, the assistant can talk about your decision but can't create or save anything in dMatrix — so it ends up offering help it can't deliver. Always set up both. Some assistants do it in one step; others take two. Each guide walks you through it. You'll need a free dMatrix account — sign up at dmatrix.com.
Once set up, the assistant will:
Detection stays conservative — dMatrix only offers to capture on a clear decision signal, and never interrupts.
You don't have to wait for the assistant to notice a decision. At any point, type:
/dmatrix:decide
This works in Claude Code, Codex CLI, and Antigravity CLI. It tells the assistant to capture a decision right now — even if you're mid-conversation, or looking back at a decision you already made. The assistant will review what you've discussed and build a matrix from it.
Use it when:
shared/canonical-prompt/source.md # The single source of truth (canonical behavior)
.claude-plugin/ · .mcp.json # Claude Code plugin manifest + MCP wiring (repo root)
skills/decide/SKILL.md # The dMatrix Skill (Claude / standalone)
claude/README.md # Claude install guide (all surfaces)
openai/ # ChatGPT paste-in + Codex (AGENTS.md, config.toml)
google/antigravity/dmatrix/ # Antigravity CLI plugin bundle
mcp/connectors/ # Host-agnostic MCP connector reference
Every behavior-bearing artifact is generated from one source,
shared/canonical-prompt/source.md, by the renderer pipeline in the dMatrix monorepo
(packages/canonical-prompt). The pipeline injects the canonical body verbatim into
each surface — only the per-provider wrapper differs — and stamps a content hash
(version_hash) so every artifact stays provably in sync. To re-sync after the canonical
prompt changes, the pipeline regenerates this whole repo in one run; the artifacts here
are not edited by hand.
