ClawArena-Team: Benchmarking Subagent Orchestration and Dynamic Workflows in Language-Model Agents
The pith
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
Core claim
The paper establishes that management ability can be isolated by constraining the main agent to a fixed subagent pool with restricted direct access, and that the resulting Subagent-Management Score shows privilege granting as the primary performance limiter across tested models, with cost decoupled from quality and behavioral diversity hidden by score clustering.
What carries the argument
The Subagent-Management Score (SMS), which multiplies task correctness by a least-privilege factor and a modality-routing factor applied to execution outcomes.
Load-bearing premise
Score differences measure only management skill because the subagent pool is fixed and locally served, independent of any variation in subagent capability.
What would settle it
Observing a model that grants workspace permissions with greater than 50 percent precision while still achieving high task correctness would indicate that privilege granting is not the dominant bottleneck.
If this is right
- Raising permission precision directly increases overall management scores for any given level of task correctness.
- Models at the low end of the cost range can match or exceed far more expensive models in management quality.
- Similar overall scores can conceal large differences in how models structure workflows and handle asynchronous subagent returns.
- Agent management can be evaluated without an LLM judge when outcomes are measured through execution.
Where Pith is reading between the lines
- Real deployments may need external permission safeguards because model judgment alone does not reach usable precision.
- Testing the benchmark with variable subagent capabilities could show whether management skill interacts with differences in subagent strength.
- The tight clustering of scores suggests current models share similar limits that may require new architectures to exceed.
Editorial analysis
A structured set of objections, weighed in public.
Referee Report
Summary. The manuscript introduces ClawArena-Team, a benchmark of 41 multi-turn, multimodal, multi-directory scenarios (258 evaluation rounds, 72 staged updates) to measure LLM agents' subagent orchestration and management ability. The main agent is deliberately restricted to text-only native perception and partial workspace access while commanding a fixed, locally served subagent pool; scoring uses an execution-based Subagent-Management Score (SMS) that multiplies task correctness by least-privilege and modality-routing factors, with no LLM judge. Experiments on twelve models report that privilege granting is the primary bottleneck (no model exceeds 50% workspace-permission precision), that API cost and management quality are decoupled (cost spans >100x while scores span <4x), and that leaderboard scores cluster within a 9.9-point band while orchestration behaviors diverge by more than an order of magnitude. Code is released at https://github.com/aiming-lab/ClawArena.
Significance. If the fixed-subagent-pool isolation is successfully enforced, the benchmark supplies a reproducible, execution-based instrument that separates management skill from raw subagent capability and perception, addressing a gap in existing agent evaluations. The public code release and avoidance of LLM judges are concrete strengths that enable external checking. The reported decoupling of cost from quality and the privilege-granting bottleneck, if substantiated, would supply actionable guidance for agent-system design.
major comments (2)
- [Abstract] Abstract: the central claim that 'score differences reflect management skill, not raw capability' rests on the premise of a fixed, locally served subagent pool being uniformly enforced; the abstract supplies no implementation details on pool standardization, local serving, or verification that subagent capabilities are identical across the twelve models, which is load-bearing for the isolation result.
- [Abstract] Abstract: quantitative claims such as 'no model exceeds 50% workspace-permission precision', 'API cost spans over 100 times', and 'overall score spans under 4 times' are presented at high level without reference to data tables, per-model breakdowns, error analysis, or statistical tests, preventing assessment of robustness.
minor comments (2)
- [Abstract] The abstract mentions '72 staged updates' and '258 evaluation rounds' without explaining their role in scenario construction or how they affect the SMS calculation.
- The manuscript would benefit from an explicit methods subsection describing the 41 scenarios and the precise definition of the least-privilege and modality-routing factors in the SMS formula.
Simulated Author's Rebuttal
We thank the referee for the detailed feedback on the abstract. We agree that additional clarity in the abstract would strengthen the presentation of our claims and have made partial revisions accordingly.

Referee: [Abstract] Abstract: the central claim that 'score differences reflect management skill, not raw capability' rests on the premise of a fixed, locally served subagent pool being uniformly enforced; the abstract supplies no implementation details on pool standardization, local serving, or verification that subagent capabilities are identical across the twelve models, which is load-bearing for the isolation result.
Authors: While the abstract is space-constrained, the manuscript body (Section 3) fully specifies the fixed subagent pool, its local serving, standardization across models, and verification of identical capabilities. To better support the isolation claim in the abstract, we will add a brief reference to the standardized pool. This revision clarifies the premise without altering the core contribution. revision: partial

Authors: The abstract summarizes findings detailed in the results (Table 2 for per-model breakdowns of precision, costs, and scores; Section 4 for error analysis and the observed spans; appendix for statistical tests). We will revise the abstract to include inline references such as '(Table 2)' for the quantitative claims to improve traceability, while noting that full robustness assessment requires the main text. revision: partial
Circularity Check
No significant circularity
full rationale
The paper introduces ClawArena-Team as a new benchmark with an explicit design premise (fixed, locally served subagent pool) stated upfront to isolate management skill. The Subagent-Management Score (SMS) is defined directly from execution outcomes (task correctness multiplied by least-privilege and modality-routing factors) with no equations that fit parameters to the evaluated runs and then rename those fits as predictions. No self-citation chains, uniqueness theorems, or ansatzes are invoked to justify core claims. All reported findings (privilege bottleneck, cost decoupling, score clustering) derive from the benchmark execution itself, which is externally verifiable via the released code. This is a standard benchmark construction with no reduction of outputs to inputs by construction.
Axiom & Free-Parameter Ledger
read the original abstract
Production large language-model (LLM) agents are increasingly deployed not as lone problem-solvers but as managers: a main model creates specialized subagents, delegates work, and orchestrates their parallel, asynchronous returns through dynamic workflows. Whether one model can actually run such a team is largely unmeasured: existing benchmarks score a policy's own task-solving or a fixed multi-agent system's emergent behavior, but none isolate the management ability of the single LLM acting as leader. We introduce ClawArena-Team, a benchmark of 41 multi-turn, multimodal, multi-directory scenarios spanning 258 evaluation rounds and 72 staged updates that measures this management ability. The main agent is deliberately constrained: it natively perceives only text and directly accesses only part of the workspace. It commands a fixed, locally served subagent pool, so score differences reflect management skill, not raw capability. All scoring is execution-based with no LLM judge: an overall score -- the Subagent-Management Score (SMS) -- multiplies task correctness by a least-privilege and modality-routing factor. Across twelve proprietary, community-hosted, and self-hosted models, experiments show that the management bottleneck is privilege granting rather than perception (no model exceeds 50% workspace-permission precision); that cost and management quality are decoupled (API cost spans over 100 times while the overall score spans under 4 times, with the cheapest open models on the Pareto frontier); and that most leaderboard scores cluster within a 9.9-point band while orchestration behaviors diverge by more than an order of magnitude. Code is available at https://github.com/aiming-lab/ClawArena.

Model or Harness? An Interaction-Centric Taxonomy for Localizing Agent Failures
The paper introduces a 41-mode taxonomy that assigns each agent failure to an interaction edge and a fault side, and shows LLM judges can reproduce the labels with Cohen's κ=0.76.
