Terminal-agent RL
Full recorded reasoning, tool calls/results, generated code, and experiment artifacts from Qwen3.5-9B terminal-agent RL.
Four views:
- Tasks: 216 instructions and screening records, split into
train(80),validation(23), andscreening_only(113). - Rollouts: all 12,134 episode snapshots, representing 11,737 unique IDs. Native full-content paths and line numbers are retained; repeated snapshots are not extra attempts.
- Results:
screening(1,728),validation_base(184), andvalidation_step10(184). The 17 screening infrastructure errors retain null rewards. - Training selection: all 1,394 returned final-training episodes, including 640 accepted for updates, with policy and update labels.
from datasets import load_dataset
tasks = load_dataset("suunny/terminal-agent-rl", "tasks", split="validation")
results = load_dataset("suunny/terminal-agent-rl", "results", split="validation_step10")
The trained adapter passed 83/184 held-out attempts versus 91/184 for the base. This run did not show improvement. Screening selected tasks with 2–6 passes in eight valid attempts (25–75%).
The viewer is an index, not a replacement for the full traces. Follow artifact and line into native JSONL; decompress .zst with zstandard. Do not execute generated code. Historical campaigns retain their identities; final_task_assignment identifies membership in the final split, not the purpose of an earlier run.
All original tables, native artifacts, coverage, and audit details remain downloadable. Viewer validation records the joins and counts. No original data was deleted or deduplicated for this layout.
Task sources are AI& TermGrade and its BandCentral subset, both Apache-2.0. Attribution covers source revisions and embedded third-party material. Credentials are redacted. The archive contains tests and solutions, so it is not an uncontaminated benchmark training set.
