The pith
Explicit state management outperforms workspace isolation for multi-agent collaboration
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
Core claim
STORM manages agent states by mediating their interactions with the shared workspace, ensuring that each agent operates on a consistent view of the codebase and that conflicting edits are detected and resolved at write time, which outperforms the git-worktree-based baseline by +18.7 on Commit0-Lite and +1.4 on PaperBench.
What carries the argument
The state-oriented mediator in STORM that tracks agent interactions with the shared workspace to enforce consistent views and resolve conflicts at the point of writing.
If this is right
- Conflicts are resolved during the write operation rather than through expensive post-hoc merges after agents complete their work.
- STORM integrates into any existing multi-agent system without requiring changes to the agents' internal logic.
- Higher overall task success rates are achieved on concurrent editing benchmarks when state management replaces workspace isolation.
- Combining the multi-agent state-managed runs with single-agent executions produces the highest scores on the evaluated tasks.
Where Pith is reading between the lines
- The same mediation approach could extend to non-code shared resources, such as multi-agent updates to a common knowledge base or simulation state.
- Testing on larger real-world repositories would show whether the early conflict resolution scales without introducing new bottlenecks.
- The reported cost efficiency opens the possibility of using STORM in resource-constrained deployments where repeated merges would otherwise waste compute.
Load-bearing premise
The benchmarks Commit0 and PaperBench, along with the specific implementation of conflict detection and resolution, are representative of real multi-agent collaboration scenarios and that performance gains are attributable to the state management mechanism.
What would settle it
A direct comparison on a new codebase with deliberately introduced concurrent edit conflicts, measuring whether integration failure rates drop under state mediation versus post-hoc workspace merging.

read the original abstract
Recent advances in multi-agent systems have shown great potential for solving complex tasks. However, when multiple agents edit a shared codebase concurrently, their changes can silently conflict and inconsistent views lead to integration failures. Existing multi-agent systems address this through workspace isolation (e.g., one git worktree per agent), but this defers conflict resolution to a post-hoc merge step where recovery is expensive. In this paper, we propose STORM, i.e., STate-ORiented Management for multi-agent collaboration. Specifically, STORM manages agent states by mediating their interactions with the shared workspace, ensuring that each agent operates on a consistent view of the codebase and that conflicting edits are detected and resolved at write time. We evaluate STORM on Commit0 and PaperBench across multiple LLMs. STORM outperforms the git-worktree-based multi-agent baseline by +18.7 on Commit0-Lite and +1.4 on PaperBench, while achieving comparable or better cost efficiency. Combined with single-agent runs, STORM reaches highest scores of 87.6 and 78.2 on the two benchmarks respectively, suggesting that explicit state management is a more effective foundation for multi-agent collaboration than workspace isolation. STORM can also be plugged into any multi-agent system seamlessly.

Referee Report
Summary. The paper introduces STORM (STate-ORiented Management), a framework for multi-agent collaboration on shared codebases. Unlike workspace isolation approaches such as per-agent git worktrees, STORM mediates agent interactions with a shared workspace to maintain consistent views and detect/resolve conflicts at write time. Evaluated on Commit0 and PaperBench across multiple LLMs, STORM outperforms a git-worktree baseline by +18.7 points on Commit0-Lite and +1.4 on PaperBench, reaching combined highest scores of 87.6 and 78.2. The central claim is that explicit state management provides a more effective foundation for multi-agent collaboration than workspace isolation, and that STORM can be plugged into existing multi-agent systems.
Significance. If the performance deltas are causally due to the state-management abstraction, the work could shift design patterns in multi-agent coding systems toward shared consistent state rather than deferred merges. The plug-in compatibility is a practical advantage for adoption. The empirical nature of the contribution means significance hinges on verification that gains are not artifacts of benchmark choice or unablated implementation details.
major comments (2)
- Abstract: the central performance claim (+18.7 on Commit0-Lite, +1.4 on PaperBench) is presented without any mention of experimental controls, number of trials, statistical tests, error bars, or data exclusion rules. This directly undermines verification of whether the reported gains support the claim that state management outperforms workspace isolation.
- Evaluation / baseline comparison: the manuscript contrasts STORM against a git-worktree baseline but provides no ablation that holds conflict detection, resolution, merging, and locking logic fixed while toggling only the isolation mechanism (shared consistent state vs. per-agent workspaces). Without this control, the observed deltas cannot be confidently attributed to the state-oriented architecture rather than differences in how STORM implements write-time mediation.
minor comments (1)
- Abstract: the statement that STORM 'can also be plugged into any multi-agent system seamlessly' would benefit from a brief description or pseudocode of the integration interface in the main text.

Referee: Abstract: the central performance claim (+18.7 on Commit0-Lite, +1.4 on PaperBench) is presented without any mention of experimental controls, number of trials, statistical tests, error bars, or data exclusion rules. This directly undermines verification of whether the reported gains support the claim that state management outperforms workspace isolation.
Authors: We agree that the abstract would benefit from additional context on the experimental protocol. In the revised manuscript we will update the abstract to note that results are reported as averages over multiple independent trials with standard deviations, following standard statistical practices for the benchmarks. Full details on the number of runs, controls, error bars, and any data exclusion criteria already appear in the Evaluation section; the abstract revision will provide sufficient high-level information to support the reported deltas without requiring readers to consult the body for basic verification. revision: yes

Authors: We acknowledge the value of a more tightly controlled ablation. The git-worktree baseline implements the standard per-agent isolation approach used in prior multi-agent coding systems, without STORM's shared-state mediation. To address the referee's concern, we will add a new ablation experiment in the revision that attempts to hold conflict detection, resolution, and locking logic as constant as possible while varying only the workspace isolation mechanism. We note that complete decoupling may introduce implementation artifacts, but the added study will help clarify the contribution of the shared consistent state. revision: partial
Circularity Check
No circularity: empirical results are direct measurements
full rationale
The paper proposes the STORM system for explicit state management in multi-agent collaboration and reports performance deltas (+18.7 on Commit0-Lite, +1.4 on PaperBench) from direct experimental comparison against a git-worktree baseline. No derivation chain, fitted parameters renamed as predictions, or self-citation load-bearing steps exist; the central claim follows from benchmark outcomes on external tasks without reducing to inputs by construction. The evaluation is self-contained against the stated benchmarks.
