dsh-chatgpt-web

You already have a free ChatGPT Web account but cannot tap into it as a conversational model source inside DeepSeek Harness. dsh-chatgpt-web closes that gap by taking over the chatgpt.com session through local Playwright browser automation, turning your existing ChatGPT Web into a zero-cost, streaming conversational model provider inside DSH with no OpenAI API key or credit card required.

The plugin operates in a pure-chat mode focused on explanations, Q&A, brainstorming, and short code-snippet generation, deliberately avoiding the prompt bloat and syntax hallucinations that come with multi-tool autonomous execution loops. Its full lifecycle is managed through DSH's Cordis mechanism: the background sidecar starts automatically on launch and shuts down cleanly on exit. It also dynamically detects your ChatGPT tier, defaulting free accounts to Luna and automatically exposing paid models such as GPT-4o and o1 for Plus or Team subscribers. Streaming Markdown and fenced code blocks are pushed in real time to the DSH Web UI or CLI.

It is well suited for developers who want a zero-cost sidecar assistant for everyday explanations, quick Q&A, and short code snippets. Keep in mind that it runs within a single browser tab with sequential queries, so it is not designed for parallel multi-subagent swarms targeting the same window, and it does not execute local filesystem or terminal operations.
