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.

source-grounded
dsh-codex is an installable DeepSeek Harness provider plugin that interfaces with a locally authenticated Codex app server. It exposes the 'codex' provider route to DSH, mapping text messages, reasoning effort, streaming, cancellation, and token usage to the Codex JSON-RPC stdio protocol without directly handling credentials or OAuth flows.

Key Capabilities

  • Integrates the Codex provider route directly into DeepSeek Harness LLM workflows
  • Communicates over validated JSON-RPC via JSONL stdio with a local Codex app server child process
  • Supports model selection, streaming output, reasoning effort configuration, and turn cancellation
  • Provides an experimental dynamic tool bridge mapping DSH tool catalogs to Codex turns
  • Preserves session state across host restarts using Codex thread IDs

Useful For

  • Accessing ChatGPT subscription-backed models and execution directly from DeepSeek Harness
  • Running local agent workflows using Codex sandbox policies and approvals within DSH
  • Bridging DSH tool calls to Codex agent sessions via opt-in experimental tool support

Who It Fits

  • DeepSeek Harness developers utilizing ChatGPT subscriptions through local Codex CLI authentication
  • Developers looking to route LLM queries through a locally running Codex app-server

Documented Limitations

  • Requires a local Codex CLI installation with active login credentials
  • Does not manage OAuth, credential storage, or make direct API calls to OpenAI
  • Experimental dynamic tool bridge is text-only, not available for ephemeral sessions, and cannot replay threads after restarts
