CommonGround Kernel
VerifiedOpen-source kernel for durable, shared multi-agent work records.
What is CommonGround Kernel?
CommonGround Kernel acts as the retained public substrate beneath agent runtimes and orchestration tools. It records requested work, handoffs, outputs, and termination reasons so later humans or agents can inspect and continue tasks without starting from fragments.
The system treats each Turn as the core durable unit that owns its inputs, observations, and deliverables. Explicit causal links between turns allow recovery even after original sessions or runtimes disappear.
It targets teams building real multi-agent processes that cross people, tools, and time. Developers and operators who need inspectable, resumable work records benefit most from its small constitutional ledger approach.
What you can build with CommonGround Kernel
Cross-session research handoff
An agent researches market data and records findings in a Turn; a later agent or human reviews the same public record to draft strategy without repeating queries.
Multi-runtime task recovery
Work started in one runtime pauses and resumes in another because boundary inputs, outputs, and evidence stay stored in the kernel ledger.
Audit and reuse of agent output
Organizations keep explicit causal lineage and artifact references so completed agent work can be audited, reused, or extended by future participants.

CommonGround Kernel: pros & cons
Pros
- +Keeps shared work facts public and durable across participants
- +Minimal kernel design avoids locking users into one runtime or memory model
- +Explicit causality supports later inspection and recovery
- +Open-source with clear focus on agent identity and turn boundaries
Cons
- –Preview release may lack full documentation and stability
- –Requires separate higher-layer tools for complete workflows
- –PostgreSQL dependency adds setup overhead for simple use cases
Frequently asked questions
No, it is a small ledger kernel that supplies durable public records; full orchestration and memory live in other layers.
