DeepSeek Harness tool plugin that generates images through Codex CLI (gpt-image-2) and previews results inline in the Web UI.
Install
No clear install command was found in the current repository evidence.
Plugin Overview & Capabilities
AI-assisted organization based on the public repository snapshot. The content must be grounded in source evidence and does not replace compatibility or security verification.
Key Capabilities
- Registers image_gen(prompt, file_name, run_in_background?) for agent use.
- Runs codex exec through the Harness subprocess interface.
- Writes generated images under the session workspace images/ directory.
- Defaults to background execution and returns a job ID for collection with job_output.
- Adds a Web UI tool view that polls a plugin RPC endpoint and displays generated images inline.
- Persists UI-only artifact descriptors so supported Web sessions can replay previews after refresh or restart while the session and file remain available.
- Supports configuration of the Codex executable, generation timeout, termination grace period, image preview size cap, and child-process environment variables.
Useful For
- Let an agent generate illustrations, icons, or other image assets from natural-language prompts.
- Save generated images into a Harness session workspace for later use in a task.
- Review generated images directly in the DeepSeek Harness Web UI.
- Run longer image-generation requests as background jobs.
Who It Fits
- DeepSeek Harness users running the Web profile.
- Users authenticated to Codex CLI with a ChatGPT account.
- Agent workflow builders who need image generation in session workspaces.
Documented Limitations
- Requires a separately installed and logged-in @openai/codex CLI.
- The inline preview requires the Web client layer and connection service; CLI and headless profiles retain text-only behavior.
- Generation is documented as taking roughly one minute and foreground calls are bounded by timeoutMs, which defaults to 300000 ms.
- Git-based installation runs the prepare build script and pnpm 10 or later may require build authorization.
- Preview replay depends on the persisted session and generated file still existing.
- The README documents Codex installation and host issues on Windows.
