reins

Shared context for teams that build with AI coding agents.

Live: reinshq.vercel.app · install the hook: npx reins-hook install

What it is

When a team codes with AI agents, each person's agent works on its own. Nobody can easily see what a teammate's agent is doing, so people duplicate work, edit the same files without knowing, and fall back to standups and a context.md that goes stale within a day.

Reins watches what each agent is doing, summarizes it into a short per-person and per-team status, and makes that status available in two places: a dashboard a admin can read, and an MCP server any teammate's agent can query before it starts work.

It is a small project, built for the 0G Zero Cup. The capture, the distillation, and the retrieval all work end to end today.

How it works

Claude Code hook  ->  reins server  ->  distill (triage, extract, reconcile, rollup)
                          |
                          |-- dashboard (Next.js, live over SSE)
                          |-- MCP server (reins_context, reins_pull_context, ...)

A hook in each teammate's Claude Code posts their prompts and agent turns to the reins server. The server runs each event through a short pipeline and keeps a current status per person and per project. The dashboard streams updates over SSE, and the MCP server lets any agent pull the same status as plain markdown.

The distillation pipeline

Each incoming event is processed in steps so that most of the noise is dropped early:

1. Triage (fast model) sorts the event into noise, minor, or major. Low-value events stop here.
2. Extract pulls structured facts: intent, actions, files touched, decisions, blockers, next steps.
3. Reconcile merges those facts into the person's current status by calling tools that update state: set_headline, set_goal, set_status, add_timeline, add_pending, resolve_pending, set_working_on.
4. Rollup (debounced) summarizes the whole team for a lead: a short status, goal alignment, collisions (two people in the same file), and risks.

If no inference backend is configured, Reins still captures raw events but does not distill them.

Where 0G fits

• Inference runs on 0G Compute. The whole pipeline above calls the 0G Private Computer router, which is OpenAI compatible.
• Snapshots live on 0G Storage. Each context snapshot is written to 0G Storage and addressed by its Merkle root hash, so the shared context can be pulled and verified from anywhere, not only from this server's database. The MCP reins_pull_context tool rebuilds a snapshot from a hash alone, with no local state, which is something a plain database cannot do.

What works today

The pipeline is built around teams of people who each run a coding agent. What is working now:

• Capture from Claude Code through a hook, installed with one command.
• Distillation on 0G Compute: triage, extract, reconcile, and a debounced team rollup.
• A current status per person (headline, goal, what they are working on, recent timeline, pending items).
• A team rollup for a lead: summary, goal alignment, file collisions, and risks.
• Handoffs and @mentions, created automatically when two agents touch the same file or one is blocked on another's work.
• A live dashboard over SSE, and an MCP server so any teammate's agent can read or write the shared context.
• Verifiable, portable snapshots on 0G Storage, including reins_pull_context to rebuild context from a hash.
• Multi-tenant auth (workspaces and tokens) and a simple deploy to Vercel plus a small VM.

Roadmap

• More agent harnesses. Today capture is wired for Claude Code. Add hooks for other coding agents (Cursor, opencode, pi, Aider, codex, koda and more) so a team on mixed tools still shares one context.
• Agents and sub-agents without a human in the loop. Capture from agents running in autonomous loops, and from sub-agents that a parent agent fans out, so the shared context keeps updating even when nobody is typing.
• Agents that act on the context. Let an agent claim and resolve pending work through the MCP write tools, so up-for-grabs items get picked up without a person.
• Cross-instance sync over 0G Storage. Two teams hand over a single root hash to share context, with no shared server.
• Optional on-chain anchoring on 0G Chain, so the history of snapshot hashes is a tamper-evident audit trail.
• Smarter retrieval that ranks and trims context, so an agent pulls only what is relevant to its task.
• Digests to Slack or Discord for the humans who still want a glance.

Quick start

npm run install:all

# 1) configure inference (runs on 0G Compute, via the 0G Private Computer router)
cp server/.env.example server/.env
#   set REINS_LLM_PROVIDER=0g-router, OG_ROUTER_API_KEY, REINS_LLM_MODEL, OG_STORAGE=on
#   (or REINS_LLM_PROVIDER=openai with REINS_LLM_BASE_URL for any OpenAI-compatible endpoint)

# 2) run server + dashboard
npm run dev
#   server    on http://localhost:4319
#   dashboard on http://localhost:4320

# 3) optional: populate a demo board without wiring agents
npm run seed

Connect an agent

One command installs the capture hook into Claude Code:

npx reins-hook install --url http://localhost:4319 --me yourname
# then run /hooks in Claude Code to approve it

Every prompt and agent turn now flows into Reins. See hooks/README.md for flags (--global, --project, --key) and the status and uninstall commands.

Pull context from an agent (MCP)

Register the MCP server so a teammate's agent can read the shared context:

{ "mcpServers": { "reins": { "command": "npx", "args": ["tsx", "server/src/mcp.ts"], "cwd": "/ABS/PATH/reins" } } }

Tools:

• reins_context reads a project's current status, fetched and verified from 0G Storage.
• reins_pull_context rebuilds a snapshot from a 0G Storage root hash alone, with no database.
• reins_projects, reins_member, reins_pending, reins_handoffs for narrower reads.
• reins_note, reins_claim, reins_resolve, reins_handoff_ack let an agent write back.

Layout

Path	What
server/	Express ingest, SSE, REST, SQLite, the distillation pipeline, the MCP server
web/	Next.js dashboard, light editorial theme, live over SSE
cli/	reins-hook, the npx installer that bundles the capture hook
hooks/	Hook docs (the hook itself ships inside cli/)
deploy/	DEPLOY.md and the deploy scripts

Auth and deploy

Local dev runs as a single open instance (REINS_AUTH=off). For a shared instance, turn on multi-tenant auth: workspaces are the tenant boundary, ingest tokens authenticate hooks and agents, access tokens authenticate dashboard viewers (httpOnly session cookie), and admin tokens mint or revoke tokens. Bootstrap with npm run admin -- create-workspace "Team".

The dashboard deploys to Vercel and the server with its SQLite database to a small VM. The dashboard proxies /api/* to the backend so the browser stays first party. See deploy/DEPLOY.md.

Configuration

All server config is environment variables (server/.env, see server/.env.example). Inference runs on 0G Compute (REINS_LLM_PROVIDER=0g-router with OG_ROUTER_API_KEY) and snapshots persist to 0G Storage (OG_STORAGE=on). To use a different inference backend, set REINS_LLM_PROVIDER=openai with REINS_LLM_BASE_URL and any OpenAI-compatible endpoint.
