// graph-driven development

Accountable change begins with understanding why.

Git records what changed, Atomic can tell you why. You can't trust a change you can't explain.

Atomic is source code management reimagined at the primitive level: a distributed, agent-native Git alternative. A single CLI connects semantic call graphs and enhanced code search to intents, acceptance criteria, tasks, changes, evidence, provenance, attestations, reviews, views, and memories in one causal graph shared by every agent you already use. Stable change identities keep those relationships intact as work is combined or reorganized, so the graph becomes the state agents work from. Not another audit trail assembled after the fact.

Install Atomic→ Why the graph is the system

// 01 · semantic understanding

Your agents answer better questions when the codebase knows itself.

Atomic enriches every repository with AST analysis, tree-sitter entity extraction, and a semantic graph that operates at the function, class, and token level. Agents stop grepping through files and start querying a graph that understands what your code means, not just what it contains.

44%

Faster sessions

Measured against baseline agents on the same task set.

82%

Less context read

Token budget saved by querying the graph instead of grepping files.

1 call

Replaces 5 tool turns

A single query returns what would take a standard agent five reads.

// 02 · provenance & attestation

Every agent turn. Every decision. Every model. Permanently recorded.

Atomic captures the full causal graph of every agent session: what was requested, what was explored, what was read, what was modified, and why. The record is cryptographically signed, content-addressed, and bound to an immutable change identity.

●
Travels with the code
Provenance is bound to the change, not the branch. Squash, rebase, or cherry-pick: the record follows.
●
Your favorite agent is already supported
Atomic plugins pre-configured to integrate into your existing agents supporting custom prompts and skills to drive your agent workflows with intent
●
Cryptographically signed
Each session is ed25519-signed and content-addressed. Tamper with one byte and the chain breaks.
●
Queryable by intent
Find every line of code produced under a specific intent, by a specific model, on a specific file.

// 03 · agent compatibility

Works with the agents you already use.

Atomic works alongside the agents you already use. A few lines of configuration wire up provenance capture per agent: you don't change your workflow, you gain a complete record of everything your agents have ever done, queryable by intent, model, file, or decision.
