ContextGraph

Stop losing agent context. ContextGraph is the memory backend for coding agents and multi-agent teams. Capture durable facts, compile trusted context packs, and make agent state visible with reactive checkpoints and repo-local memory directories.

Why It Stands Out

Most agent memory tools either store raw text in a vector database or replace long sessions with one lossy summary.

ContextGraph is built for the gap between those two:

• governed shared memory so agents can reuse facts without losing provenance, freshness, or access control
• context packs so agents get token-budgeted, explainable context instead of opaque recall results
• reactive delta compaction so coding agents can checkpoint decisions, open tasks, blockers, and changed files before the context window collapses
• branch-aware context cache so child sessions can reuse shared checkpoint prefixes instead of recompiling everything from scratch
• .contextgraph/ memory directories so the latest session state is inspectable in the repo, not trapped inside one response payload

If you want memory that is inspectable, team-safe, and useful during real work, this is the wedge.

Start Here

The fastest path to understand the repo is:

1. run the 2-minute setup in examples/beta_quickstart.py
2. run the coding-agent continuity demo in examples/reactive_delta_compaction_demo.py
3. inspect the generated .contextgraph/ folder from that demo to see resume prompts, open tasks, failures, and branch/cache metadata
4. run the governed retrieval demo in examples/context_pack_demo.py
