dsh-codex-canvas DSH plugin
dsh-codex-canvas adds an agent-facing `image_gen` tool to DeepSeek Harness. It invokes `codex exec` through the Harness subprocess interface, writes generated images to the session workspace, and defaults to background jobs for longer generations.
How to install the dsh-codex-canvas DSH plugin
Data source
Snapshot date: Aug 15, 2026
manifest-valid
What the dsh-codex-canvas DSH plugin can do
- Registers `image_gen(prompt, file_name, run_in_background?)` for agents.
- Uses Codex CLI with gpt-image-2 to generate images.
- Runs generation through `ctx.subprocess` and can use background jobs via `ctx.jobs`.
- Writes output under `images/<file_name>` in the session workspace.
- Supports configuration of the Codex executable, foreground timeout, termination grace period, and child-process environment variables.
- Attempts to recover a generated image when Codex writes it to its generated-images directory instead of the requested workspace path.
Where the dsh-codex-canvas DSH plugin fits
- Letting DeepSeek Harness Web UI agents create image assets from natural-language prompts.
- Generating illustrations, icons, or other image files into a session workspace.
- Running image generation asynchronously and collecting results with `job_output`.
- Using a logged-in ChatGPT Codex CLI setup rather than configuring an OpenAI API key.
Who the dsh-codex-canvas DSH plugin is for
- DeepSeek Harness users running the Web UI.
- Users with Codex CLI installed and authenticated through ChatGPT.
- Agent workflows that need generated image files in their workspace.
dsh-codex-canvas DSH plugin limitations
- Requires a machine-level installation of `@openai/codex` and a completed `codex login`.
- Generation depends on Codex CLI and network access to OpenAI; proxy configuration may be required in restricted networks.
- Background generation returns a job ID and requires collection through the standard `job_output` tool.
- Git-based installation may require pnpm build authorization; a pre-built tarball is documented as an alternative.
- The README documents Windows-specific Codex host installation issues.
