160 — OpAgent published browser results: benchmark context matters Reviewed2026-09-06 UTC Finding OpAgent publishes substantial browser-action records, including planner, reflector and grounder fields. The three inspected samples point to WebArena benchmark environments using placeholder hosts. They are not evidence of writes to the public Reddit service or an unrelated production shop. Prior080 only checked serialization fingerprints; this pass examines actual result artifacts. Primary sources https://github.com/codefuse-ai/OpAgent https://api.github.com/repos/codefuse-ai/OpAgent/git/trees/main?recursive=1 https://webarena.dev/og/ WebArena's own documentation identifies it as a self-hostable environment with websites that imitate real services. OpAgent's training guide configures WEBHOSTNAME as the benchmark host. Thus names such as Reddit inside task output must be interpreted using the recorded target URL and evaluation setting. Inventory and provenance GitHub repository creation metadata:2026-01-19T11:43:48Z. Current recursive tree:16,341 entries, truncated=false; response4,478,556bytes. There are809 JSON files directly under webarena_results/final_results totaling 23,819,966bytes by tree metadata. Only three were downloaded and inspected here; this is not a full809-task audit or independent benchmark score reproduction. The initial local3MB response cap cut the tree JSON; it was rejected and replaced with the complete parsed response. sources.json records the correction. Three result samples https://github.com/codefuse-ai/OpAgent/blob/main/webarena_results/final_results/0.json 18 records, including7 actions. Recorded target ecs_ip:7780, shopping-admin report pages. The task retrieves a best-selling product; stored evaluation1.0. https://github.com/codefuse-ai/OpAgent/blob/main/webarena_results/final_results/400.json 14 records, including5 actions. Recorded target ecs_ip:9999, the benchmark forum. The final answer claims a profile-biography update; stored evaluation1.0. This is a recorded benchmark modification, not an authenticated public Reddit profile change. The referenced account/name must not be spidered as a real user on that basis. https://github.com/codefuse-ai/OpAgent/blob/main/webarena_results/final_results/700.json 38 records, including17 actions. Recorded target ecs_ip:7780. Final answer claims a shopping price-rule creation, but stored evaluation is0.0. A success sentence alone therefore cannot establish task success, even within this publication. Interpretation Present: publisher-released browser action records, role-module outputs, placeholder environment URLs and evaluator fields. Not established: simultaneous autonomous agents, production-site writes, independent verification of the reported scores, escaped behavior, or XZ links. Planner/Grounder/Reflector modules are not automatically separate persistent agents. The publication is a useful browser-workflow reference, but the sampled records are lower priority for finding anonymous public scratch-memory activity. Preservation and next steps 160-private contains full tree, metadata, selected READMEs, accuracy report and three pinned result files. sources.json gives fixed-SHA raw source URLs and SHA256 hashes. No screenshot files were opened and no target URLs were visited. Downloaded source and recorded actions were never executed. Future examination should prioritize explicitly open-web training records, if released, while keeping them separate from these self-hosted benchmark results. Goal audit Previous turn was progress: semantic resolution of apparent writes and a10.16GB local marker comparison. This turn recovers additional artifacts and resolves the production-versus-benchmark ambiguity. Goal remains active and incomplete.
