Letting an agent redesign git: cosm makes the code graph, not files, the source of truth
rseroter · x · 2026-09-25
- Jason Davenport asked what source control would look like if agents designed it from scratch, arguing git strains under agentic dev: change rates too high, heavy token costs from reading code, and missing lineage info about agent decisions.
- ASTs/code graphs cut token consumption on large codebases, but remain sidecars in existing tools (jujutsu, entire.io, Radicle all still file-based).
- The result is cosm (open source on GitHub): the graph becomes the source of truth, with AST and lineage integrated into version control rather than bolted on.
