DevCD is the current working name for one conviction: AI agents should know what you are trying to continue without you having to tell them every time.
Today, every agentic tool starts with a blank slate. You paste context. You explain what happened. You re-describe the task that was already described in three other places. The next agent repeats failed attempts because it cannot see what already went wrong. Context is not portable, not structured, and not policy-governed.
DevCD is a local-first Agent Continuity Layer that sits between a person's working environment and the agents that assist it.
It is not a model, a chat interface, a task runner, a remote exporter, or a telemetry service. It is a local, structured source of truth about what is happening right now that survives session boundaries and expresses continuity through a typed, policy-filtered Continuity Packet.
The first mature proof is developer workflow continuity: coding agents resume from goal, failure history, and stale attempts recorded locally. Context Packs define a path for other domains without adding remote dependencies; the current research pack is exercised through synthetic metadata-only events.
-
Local-first, always. Work context is sensitive. Observation runs locally by default. Remote export requires explicit configuration and policy.
-
Explicit policy. Every observation or action passes through a policy decision that can be inspected, logged, and reasoned about. No implicit side effects.
-
Structured state, not raw text. Events are normalized. State is typed. Memory has scope and TTL. Agents receive structured context, not raw file diffs.
-
Vertical Slice Architecture. Each feature domain — events, state, memory, policy, ambient context — owns its models, services, and tests. The kernel stays intentionally small.
-
Zero vendor lock-in. The protocol is MCP-compatible. The storage is local JSON Lines. The daemon runs on any POSIX-compatible machine.
