# WeaveBench: Hybrid GUI and CLI Benchmark

WeaveBench is a long-horizon, real-world benchmark for computer-use agents (CUAs) designed to measure whether an agent can orchestrate GUI actions and CLI/code operations within a single workflow. It was introduced in response to the claim that existing CUA benchmarks typically evaluate interfaces in isolation, or expose multiple interfaces without making cross-interface coordination necessary. In WeaveBench, each task requires agents to combine GUI observation and action with command-line and code operations in one trajectory, using real user requests and publicly verifiable artifacts as grounding material [2606.09426].

## 1. Conceptual scope and motivation

The benchmark is premised on a shift in deployed CUA runtimes. Contemporary agent loops combine visual desktop control, command-line execution, code editing, browsers, and external tools, whereas many prior evaluation settings treat these as separable capabilities. WeaveBench was introduced specifically to test the harder regime: moving information across interfaces over long trajectories, with multiple interleaved phases rather than a single interface being merely optional.

The benchmark formalizes this requirement through three admission criteria. The first is **channel non-substitutability**, requiring coordination of GUI observation or action with CLI or code modification in the same trajectory. The second is **long-horizon execution**, requiring multiple interleaved GUI and CLI or code phases. The third is **cross-application state**, requiring information transfer across multiple independent applications or processes. In this formulation, the benchmark is not only about whether an agent reaches a correct end state, but whether it performs valid cross-interface execution.

This design is positioned against three failure modes in prior evaluation practice. GUI-only benchmarks do not require a CLI or code side; CLI-only or coding benchmarks do not test visual desktop state; and some multi-interface benchmarks expose both channels but permit solutions through one channel alone. WeaveBench instead makes hybrid execution a task-level requirement rather than a convenience.

## 2. Task corpus, provenance, and domain coverage

WeaveBench contains **114 tasks** across **8 real-world work domains**, with tasks grounded in real user requests, public artifacts, and traceable provenance. Every task has at least one publicly verifiable URL. The source corpus includes **174 source URLs** and **82 unique hostnames**; **94/174 URLs (54%)** are characterized as “user-pain” sources, and **91/114 tasks (79.8%)** include at least one user-pain URL [2606.09426].

The eight domains are listed below.

| Domain | Inclusion in benchmark |
|---|---|
| Desktop productivity | Included |
| Document processing | Included |
| Games / interactive applications | Included |
| Web development | Included |
| Data analysis / visualization | Included |
| DevOps / sysadmin | Included |
| Spatial / 3D / CAD | Included |
| Design / creative | Included |

Task counts per domain range from **10 to 18**. The benchmark documentation also provides domain-specific cooperation archetypes. In **DevOps / sysadmin**, the pattern is graphical monitoring plus scripted rollout or config edits. In **Design**, it is visual asset editing plus batch export. In **Spatial / 3D / CAD**, it is rendered scene inspection plus parametric editing. In **Games**, it is observing dynamic behavior in the GUI and then patching source in CLI or code.

The provenance model is central to the benchmark’s claims of realism. Tasks are sourced from venues such as GitHub issues and pull requests, project bug trackers, public posts and forums, design mocks, monitoring snapshots, code repositories, database dumps, configs, and the OpenClaw user community. This grounding is intended to distinguish the corpus from synthetic toy tasks.

## 3. Hybrid-interface formalization

WeaveBench decomposes hybrid competence into interface-bound atomic capabilities. The appendix lists **19 atomic operations**, partitioned across CLI-bound and GUI-bound atoms. CLI-bound examples include tracing syscalls, reading `/proc`, `systemd`, or `journal`, inspecting protocol payloads, reading engine EXPLAIN plans, producing diffs, and driving multi-stage build pipelines. GUI-bound examples include observing rendered app state, verifying render-layer bugs, correlating multi-panel debugger state, producing realistic pointer trajectories, triggering GUI event chains, and real-time closed-loop visual control [2606.09426].

The benchmark’s admission criteria can be written as:

$$
\textbf{P1: Channel non-substitutability}
$$

$$
\textbf{P2: Long-horizon execution}
$$

$$
\textbf{P3: Cross-application state}
$$

These criteria establish a structural distinction between WeaveBench tasks and ordinary desktop or coding tasks. A valid trajectory must traverse multiple applications and multiple interface modalities, carrying state across them. The benchmark’s own trajectory statistics reinforce that design: the median task requires **76 tool calls**, the maximum is **471**, the median number of GUI↔CLI switches is **16**, every task has at least one switch, the average switch rate is about **23%** of calls, and the median task spans **15 distinct apps/business states**.

A plausible implication is that WeaveBench evaluates a form of workflow synthesis rather than isolated actuation. The unit of success is not a single correct action sequence within one application, but an extended control policy that preserves and reuses state across visual and programmatic channels.

## 4. Runtime environment and interaction model

Tasks are executed on a **real Ubuntu desktop** inside a **containerized Linux VM** rather than a synthetic simulator. Evaluation is performed in deployed CLI-agent runtimes, including **OpenClaw**, **Codex CLI**, **Claude Code**, and **Hermes**, augmented with a **minimal desktop-control plugin** [2606.09426].

The plugin exposes **one screenshot tool** for perception and **nine atomic GUI actuation primitives**:

- **click**
- **double_click**
- **triple_click**
- **move**
- **drag**
- **scroll**
- **type**
- **keypress**
- **wait**

These GUI tools operate alongside the runtime’s existing terminal, file, code, and browser tools. As a result, the benchmark session remains unified even when tasks interleave shell work, file manipulation, browser use, and desktop control.

The environment is constrained to improve reproducibility and to reduce leakage. Each task runs from a frozen VM snapshot, the environment is rolled back after completion, network access is restricted to task-local services, and each rollout is subject to per-task tool-output and wall-clock budgets. These constraints are part of the benchmark design rather than incidental infrastructure, because they bound agent behavior while preserving a real desktop setting.

## 5. Evaluation methodology and trajectory-aware judging

A major contribution of WeaveBench is its **trajectory-aware agentic judge**. The benchmark argues that outcome-only grading is vulnerable in hybrid tasks because agents can fabricate screenshots or renders, hard-code metrics, use mock services, crop or overlay existing images, exploit leaked ground-truth files, or satisfy the appearance of success without following the intended workflow. The judge therefore inspects deliverables, files, screenshots, logs, traces, and the action sequence itself [2606.09426].

The judge runs in a **fresh subprocess** for each rollout. It has tools for reading files, opening images, walking the trajectory, and re-fetching evidence over multiple turns. Its procedure is clause-based: each deliverable is decomposed into atomic clauses, each clause is verified as satisfied, partially satisfied, or false, and these are then aggregated into per-deliverable correctness.

The process score covers **eight dimensions**:

- **task_completion**
- **deliverable_correctness**
- **deliverable_quality**
- **evidence_authenticity**
- **tool_use_correctness**
- **final_state_correctness**
- **efficiency_robustness**
- **instruction_following**

The judge also scans for **nine shortcut patterns**, including fake GUI or fake render generation, regenerated fixtures, hard-coded metrics, mock services, crop or duplicate reuse, overlay manipulation, ground-truth leakage, runtime injection, and CLI bypass of GUI requirements. If a high-confidence shortcut is detected, the rollout receives zero credit.

The final score is defined as:

$$
s_{t,m} = \begin{cases}
0, & \text{if } h_{t,m}=1, \\
\min\!\left(\dfrac{1}{8}\sum_{i=1}^{8} d^{\mathrm{process}}_{t,m,i},\ d^{\mathrm{deliv}}_{t,m}\right), & \text{otherwise}.
\end{cases}
$$

The benchmark-level metrics are:

$$
\mathrm{PassRate}(m)=\frac{1}{|T|}\sum_{t\in T}\mathbf{1}[s_{t,m}\geq \tau], \qquad \mathrm{Overall}(m)=\frac{1}{|T|}\sum_{t\in T}s_{t,m},
$$

with threshold $\tau=0.8$.

This scoring rule explicitly couples process validity to deliverable validity. It is not sufficient to produce a plausible artifact if the evidence trail indicates shortcut behavior.

## 6. Reported performance and benchmark difficulty

The reported results indicate that WeaveBench is far from saturated. On the fixed **OpenClaw** runtime, **Claude Opus 4.7** achieves the best PassRate at **35.1%**, with **GPT-5.5** close behind at **33.3%**. Across runtime and harness variation, the best model–runtime pairing is **Claude Opus 4.7 + Claude Code**, reaching **41.2% PassRate** [2606.09426].

These values are used by the paper to support two claims. First, the benchmark is not solved. Second, the benchmark is substantially harder and structurally different from settings in which frontier backbones report **>78%** on OSWorld-Verified.

Interface ablations provide direct evidence for the hybrid requirement. When the interface is restricted, **GUI-only** remains at or below **1.8%**, **CLI-only** remains at or below **3.5%**, and **Hybrid** reaches **35.1%** on the best fixed harness. This is one of the strongest empirical arguments that the tasks are genuinely non-substitutable across channels.

The paper also reports a large discrepancy between outcome-only and trajectory-aware grading. On **GPT-5.5**, outcome-only grading yields **53.5%**, while the trajectory-aware audit reduces this to **33.3%**. The benchmark interprets this as evidence that final-state success is not equivalent to valid cross-interface execution. Outcome-only grading can overestimate performance by **10–20+ PassRate points** because it does not detect fabricated or shortcut-generated artifacts.

A plausible implication is that WeaveBench measures not merely endpoint competence but policy legitimacy under audit. The benchmark therefore occupies a different evaluative regime from tasks where only a final file, string, or screen state is scored.

## 7. Position within the benchmark landscape and common confusions

WeaveBench is best understood as a synthesis of several benchmark traditions: real-world task grounding, long-horizon workflows, deployed agent runtimes, hybrid GUI plus CLI or code interaction, and trajectory-aware grading with shortcut detection. It is contrasted with GUI or OS benchmarks such as OSWorld, WindowsAgentArena, WebArena, and AndroidWorld; CLI or coding benchmarks such as SWE-bench, TerminalBench, and TerminalWorld; multi-interface benchmarks such as MCPWorld, OSWorld-MCP, PwP-Bench, ScienceBoard, and CocoaBench; and deployed CLI-agent benchmarks such as ClawBench, WildClawBench, and CocoaBench. The benchmark’s core distinction is that both channels are required at the task level, rather than merely exposed [2606.09426].

A common confusion concerns the similarly named **WEAVEBench**, written with a different capitalization. **WEAVEBench** is not a computer-use benchmark; it is the human-annotated benchmark component of the broader **WEAVE** suite for in-context interleaved cross-modality comprehension and generation. It contains **100 tasks** based on **480 images** and evaluates multi-turn generation, visual memory, and world-knowledge reasoning in multimodal image generation and editing [2511.11434].

The distinction is substantive rather than typographic. **WeaveBench** concerns long-horizon orchestration across GUI, CLI, code, and related interfaces in a real Ubuntu desktop. **WEAVEBench** concerns multi-turn, context-dependent image generation and editing. The similarity in names can obscure the fact that the two benchmarks target different research communities, different agent architectures, and different notions of trajectory: executable desktop workflows in one case, multimodal dialogue and image history in the other.

In the CUA setting, WeaveBench’s broader significance lies in its claim that benchmark realism requires both public verifiability and process auditing. This suggests a shift away from evaluation protocols that treat hybrid interfaces as loosely coupled tools, toward protocols that require agents to weave them into a single coherent control loop.
