What Does It Do?
dsh-error-lens is a read-only error diagnostics DSH plugin for DeepSeek Harness that turns vague "this run failed" messages into actionable information. It solves the problem of third-party OpenAI-compatible gateways returning different errors (like 401, 403, 429, 400, 5xx) that are hard to pinpoint, letting you see redacted error details directly in the DSH Web UI and copy a diagnostic report suitable for GitHub Discussions with one click. Maintained by Wanbinyu under the MIT license, it is built on the official session projection and Web UI slots with no DOM injection.
Core Features
- Shows the most recent unresolved request failure above the message input area, expandable to view the last 3 failures for comparison.
- Categorizes errors into authentication, forbidden, rate limit, context length, compatibility, timeout, network, and server errors, and displays the provider error message and Request ID persisted by DSH.
- Copies a redacted diagnostic report in Chinese or English with one click, removing API keys, Bearer tokens, URL key parameters, and user directories.
- Automatically hides the notice after the next successful turn while retaining limited in-session error statistics.
- Does not read credential storage, save full prompts, auto-retry, or modify model requests.
How to Use This Plugin?
After enabling it in DSH Web, the plugin displays an error notice above the input area when a model request fails. Click to expand and view the last 3 failures, and use the copy button to generate a redacted diagnostic report. Default configuration is in cordis.patch.yml of the Web profile, where you can adjust maxRecords (default 10, range 1-50) and maxMessageLength (default 2000, range 256-8000) to control the number of retained errors and the maximum character length per error. Note that the plugin only processes terminal failure records already present in session logs; always manually review sensitive information before copying or publishing reports.
