| # Opencode Traces |
|
|
| A collection of redacted [opencode](https://opencode.ai) session traces, published as raw data for studying agent behavior, tool-use patterns, and model anomalies. |
|
|
| ## File naming convention |
|
|
| Each trace is published as a **pair** of files: |
|
|
| | Suffix | Format | Description | |
| |---|---|---| |
| | `.redacted.md` | Markdown | Human-readable transcript: messages, reasoning, tool calls, outputs | |
| | `.redacted.jsonl` | JSONL | Raw session export (one JSON object per message, Opencode native format) | |
|
|
| Both files share the same base name: `session_<session-id>.redacted.<ext>` |
|
|
| All traces are **redacted**: hostnames, IPs, tokens, presigned-URL credentials, and passwords are replaced with `REDACTED`. No real secrets are present. |
|
|
| ## Traces |
|
|
| ### 1. `ses_f850ff37effecxAxwdMVLnS5FR` — OSS bucket hallucination |
| |
| - **Files**: `session_ses_f850ff37effecxAxwdMVLnS5FR.redacted.{md,jsonl}` |
| - **Model**: `opencode-go/qwen3.8-flash` (Qwen 3.8 Flash via Opencode Go) |
| - **Agent**: `build` |
| - **Task**: Deploy frappe/helpdesk with Docker & Tailscale HTTPS |
| - **Anomaly**: The model fabricated a presigned Alibaba OSS URL (`routify-file-proxy-sg.oss-ap-southeast-1.aliyuncs.com`) and attempted to `webfetch` it mid-task. Nothing in the context mentioned Routify, OSS, or object storage — a pure hallucination of a storage bucket endpoint. |
| - **Session**: 57 messages, 235 parts, 2026-09-07 08:15–08:52 UTC |
| |
| <details> |
| <summary>Hallucinated tool call (message 18, 08:19:02Z)</summary> |
| |
| ```json |
| { |
| "url": "https://routify-file-proxy-sg.oss-ap-southeast-1.aliyuncs.com/REDACTED?Expires=REDACTED&OSSAccessKeyId=REDACTED&Signature=REDACTED" |
| } |
| ``` |
| |
| Result: `403 Forbidden` |
| |
| </details> |
| |
| ## Use cases |
| |
| - Studying hallucination patterns in tool-use agents |
| - Evaluating model reliability on multi-step DevOps tasks |
| - Benchmarking fabrication of external resource URLs (storage buckets, presigned URLs) |
| - Regression testing for opencode / Opencode Go model routing |
