AI explores. You decide. DecRec remembers.
Shared decision memory across Claude, ChatGPT, Cursor, Codex, and other agents.

Keep accounts single-user until we validate team demand.
✓ Committed as DEC-8
Before changing the account model: DEC-8 deliberately kept accounts single-user while validating demand. Want to revisit it?
One decision. Any agent.
MCP gives the agent access to decisions. The Skill teaches it when those decisions matter.
Agent
├─ Skill → judgment: when decisions matter
└─ MCP → durable decision state
↕
DecRec
| Layer | Role |
|---|---|
| Skill | Judgment: what counts as a decision, when to recall, when to capture, when to stop. |
| MCP | Durable state: search, create, update, admit, commit, and archive decisions. |
| DecRec | The shared system of record across chats and agents. |
Tools without the skill still write; the skill without tools cannot persist across agents.
DecRec remembers decisions, not AI output. Agents can prepare and surface records; a human commits the decision.
Your agent already has access to code, chats, docs, and project context. DecRec doesn't try to remember all of it.
It keeps the smaller set of choices that constrain future work:
- what you chose
- why
- what you considered
- who committed it
- what would justify revisiting it
The goal isn't more context. It's giving a fresh agent the reasoning behind decisions already made.
-
Stay in scope — don't advance past what was asked (no catalog → shape → update → explore → admit → commit chain unless requested).
-
Recall — search only at a decision boundary (consequential choice that constrains later work). Never before ordinary coding.
-
Capture — offer once when a consequential fork settles; never auto-create; never interrupt trivia.
-
Humans commit — the agent can prepare and surface records, but it does not place commitments.
Full protocol: skills/decrec/SKILL.md. Exploration prompts: skills/decrec/explore-prompts.md.
After install, allow the MCP connection, then paste one of these into a new conversation:
Should we [option A] or [option B]?
Work through it from more than one side, then record the decision in DecRec.
Or substitute any real decision you're working through.
Here is a [Slack thread / meeting notes]. What is worth recording in DecRec? Don't record until I pick.
[paste]
We picked [option A] over [option B]. Record that decision in DecRec.

Same path on both. Skill and MCP come with the plugin.
- Customize → Plugins → Add → Add marketplace
- URL:
decrec-io/decrec-plugin - Sync → select DecRec → Install
- Allow when asked.
Marketplace plugin. Does not run in Chat.
- Open Plugins → Add → Add a marketplace.
- Source:
decrec-io/decrec-plugin - Add marketplace, then install decrec.
- Allow when asked. Start a new Work conversation.
Marketplace plugin does not run here. Add MCP and the skill on chatgpt.com.
MCP (tools only — no skill):
- Plugins → +
- Connection: Server URL
- URL:
https://decrec.io/mcp - Create. Allow when asked. Start a new conversation.
Skill:
- Download ZIP from the GitHub repo
- Plugins → Skills → + → upload that zip
Command Palette (Cmd+Shift+P / Ctrl+Shift+P), then:
Chat: Install Plugin From Source
Paste the GitHub URL and press Enter:
https://github.com/decrec-io/decrec-plugin
Copy skills/decrec/*.md (SKILL.md and explore-prompts.md) into your client's skill directory. Add an MCP connector to https://decrec.io/mcp.
Useful even if you never use DecRec. Steal these for your own agent skills.
Alternatives (≥2 paths), consequence (constrains later work), future relevance (someone will ask why).
Match the stage they requested; stop there.
Not before ordinary coding, bugfixes, or implementing an already-chosen approach.
locked, in_flight, and pin_mismatch mean stop (or reload). Don't infer from the chat and retry.
Explore from clean contexts; the agent synthesizes options, the agent does not commit.
Don't invent stack, vendors, tenancy, or business metrics the brief doesn't state.
See skills/decrec/SKILL.md for the full rules.
This plugin connects to the remote MCP server at https://decrec.io/mcp (OAuth). DecRec stores account email, organization membership, and decision content you choose to record. Details: Terms & data policy. Support: hello@decrec.io.
