Grite substrate cuts multi-agent duplicate work from 78% to 0%
Dipankar Sarkar introduces `grite`, an open-source, serverless coordination substrate embedded in git that eliminates duplicate and conflicting work among concurrent coding agents, reducing redundant task repetition from 78% to 0% while more than tripling useful throughput.
Score breakdown
The paper surfaces a pre-PR coordination layer that existing PR-history analysis cannot see, and provides a concrete substrate and mining toolkit that reduce redundant multi-agent work from 78% to 0% — directly addressing why autonomous agents' PRs are accepted less often despite being produced faster.
- 01Autonomous coding agents open PRs faster but are accepted less often — a gap PR-level telemetry cannot explain, per large-scale studies cited in the paper.
- 02`grite` is an open-source coordination substrate that stores an append-only, signed event log inside git itself, requiring no central server.
- 03Redundant work — tasks that merely re-do a teammate's completed task — falls from 78% to 0% with the shared substrate.
Dipankar Sarkar's paper identifies a fundamental blind spot in current evaluations of autonomous coding agents: large-scale studies show these agents open pull requests faster but get them accepted less often, yet PR-level telemetry cannot explain why. The paper argues the missing signal lives in the pre-PR coordination layer — specifically, in how concurrent agents claim, divide, and collide over shared work items before any code is submitted for review.
Its append-only, signed event log captures the full coordination history directly.
To study this coordination process, the paper introduces `grite`, an open-source substrate that needs no central server and stores its records inside git itself. Its append-only, signed event log captures the full coordination history directly. The paper reports three key findings: first, the shared substrate reduces duplicate and conflicting work dramatically — the share of work that merely re-does a teammate's task falls from 78% to 0%, while useful throughput more than triples. Second, every agent's copy of the log converges to the same state with no write silently dropped, a property that file-based trackers fail to guarantee under concurrent writes. Third, the log functions as a mineable artifact from which concrete failure modes — conflicting edits, lock starvation, redundant rediscovery, and race-to-close — are automatically recoverable with full provenance, several of which are invisible in pull-request history.
The paper releases the dataset, harness, and mining toolkit alongside `grite`, making the coordination substrate and its analysis infrastructure available for further research into multi-agent coding systems.
