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-lcx-codex is a DeepSeek Harness plugin that acts as a wire owner for GPT Responses sessions across ordinary turns, tool executions, Native V2 compaction, replay, session resume, and GPT model switching. It integrates GPT-5.6 prompt caching options, native history compaction checkpoints, and hosted/alpha web search tools without overriding DSH's native agent, session, and tool management.

Key Capabilities

Unified GPT Responses request and SSE wire ownership throughout conversation turns
Native V2 history compaction and replay with state persistence in checkpoints
GPT-5.6 implicit prompt caching with TTL configuration for stable topologies
Integration of GPT Hosted Search into DSH's native web search provider
Capability-probed Alpha stateful web actions (search, open, click, screenshot)
Isolated Pi 0.84.3 runtime dependency without host package overrides

Useful For

Optimizing token usage and prompt caching on long-running GPT sessions
Performing native V2 compaction and replay during context-heavy workflows
Routing web search through GPT Hosted Search and stateful browser actions on Sub2API or NewAPI endpoints
Seamlessly migrating or resuming GPT sessions across restarts and compatible route models

Who It Fits

DeepSeek Harness users leveraging GPT endpoints via Sub2API, NewAPI, or direct OpenAI routes
Developers needing granular control over prompt caching, context compaction, and SSE transport

Documented Limitations

Requires disabling LCX before switching to non-GPT models like Claude or Gemini
Dynamic tool additions from newly activated skills can reset the prompt cache epoch
Content-level prompt cache breakpoints are not supported on current routes
Alpha search capabilities fail-closed if capability probes do not pass
Credentialed ALPHA-004 runtime is explicitly not covered

DSH Compatibility

Version-specific runtime evidence collected by DSH Plugin. A missing result means we have not tested that combination yet.

Not tested yetNo runtime compatibility tests have been published yet.

Security Signals

Objective signals discovered from package metadata and source inspection. These are not a guarantee that a plugin is safe.

No automated security signals have been published yet.
