Continuity

⚠️ Alpha. This is an early alpha release (0.1.0-alpha.1). Everything here — the local and team flavors, the schema, the plugin, and the tool surface — is unstable and may change without notice. Expect rough edges and breaking changes; not yet recommended for production-critical workflows.

Coordination for parallel Claude Code sessions. When you run more than one Claude Code agent at once — across worktrees, terminals, or teammates — Continuity gives every session a shared view of:

• Presence — who else is working right now and what they're focused on
• File activity — which files other sessions have touched recently (so you don't collide)
• Decisions — typed, append-only shared decisions with explicit supersede semantics
• Task claims — atomic "I've got this issue" claims so two agents don't duplicate work
• Handoffs — structured context transfers between agents (or to a human)
• Audit log — an append-only record of every coordination event

Conflicts are loud, not silent: when two agents disagree (same decision key, same issue), the API returns a conflict instead of overwriting.

Two flavors, one codebase

	Local	Team
Storage	SQLite file on your machine	Neon Postgres
Transport	in-process	Cloudflare Worker (HTTPS + API key)
Scope	one machine, many sessions	many machines, many teammates
Auth	none (single implicit user)	per-teammate API key
Extras	coordination core only	+ GitHub Projects, plan-check, Slack escalation
Setup	zero config	deploy a Worker + Neon

The Claude Code plugin picks the flavor automatically: if you provide an API URL and key it runs in team mode; otherwise it runs local against ~/.continuity/continuity.db.

Install

In Claude Code, add this repo as a plugin marketplace and install the plugin:

/plugin marketplace add uziiuzair/continuity-mcp   # or a local path to this repo
/plugin install continuity@continuity

With no configuration it runs in local mode (SQLite, zero-config). For team mode, set the plugin's apiUrl + apiKey to your deployed Worker.

Requires Node ≥ 22. The local flavor uses Node's built-in node:sqlite (no native dependencies — the plugin bundle is pure JS and cross-platform). The launcher passes --experimental-sqlite, which is required on Node 22.x–23.x and a no-op on Node 24+.

Documentation

• Architecture — the two flavors, the ContinuityBackend seam, the data model
• Local mode — zero-config single-machine setup
• Team mode — deploying the Cloudflare Worker + Neon
• Example team setup — scoping Continuity to specific repos

Status

🚧 Early development. See IMPLEMENTATION_PLAN.md for the architecture and build phases.

Node version: Node ≥ 22 for both flavors — the local flavor uses node:sqlite (Node 22+), and the team flavor's Wrangler 4 tooling also needs Node 22+.
