Digests the images in a prompt with a vision model before admission, so any model — a text-only one included — can read them without the session ever switching models, and adds a describe_image tool for image paths.

Tavily search and page fetch: tavily_search queries with a rotating pool of up to eight API keys that backs off per key on 401/403/429 so one exhausted account does not take the tool down, and web_fetch retrieves a single page through curl, returning its HTTP status with de-tagged text.

Injects the current date and time into the runtime context on every turn, so the agent can read the time instead of inferring it.

ChatGPT-style side chat for the DSH Web GUI: ask small questions about the current topic in a floating side panel, answered by an independent lightweight session over the official /api RPC — the main conversation is never touched. Streaming text, collapsible reasoning, tool chips, stop button, agent-preset selector, and an automatic context snapshot from the visible main chat.

Radial right-click menu on conversation turns in the DSH web GUI for forking a session from a chosen turn, interrupting generation, copying the working directory path or session ID, opening the working directory, and exporting session logs.

Select text in any Windows app to explain or translate it with the Harness agent, answered in a native always-on-top overlay.

Read-only MCP server over the DSH plugin-certification registry, exposing a plugin certification grade, its snapshot and the five-dimension evidence behind it.

DSH plugin: browse local Codex projects & sessions and continue them in DSH — read ~/.codex rollouts, pick a session, resume with full context (goal + transcript + cwd).

Adds per-route context window and compaction threshold fields to the Models settings page and a vendor-aware thinking-effort picker to the composer, writing llm-pi-ai capacities, reasoningEfforts, and a compaction-basic patch row.

Adds a right-click menu to DeepSeek Harness inside desktop shells that ship no context menu: cut, copy, paste and select all in the composer, copy and copy-as-plain-text on selected text elsewhere, and a search entry that opens the default browser with a configurable engine.

MCP server management panel in Settings: add, edit, enable/disable and delete servers across user and workspace scopes with form or JSON editing, and auto-register discovered MCP tools as native conversation tools.

dsh (DeepSeek Harness) plugins for project-level persistent context: session archive with a mechanical index, memory consolidation (CONTEXT.md + MEMORY.md), low-frequency skill autolearn, and automatic handoff.

Adds a Long text button to the composer tool row: write or paste the body in an editor overlay, and on save it is written to <workspace>/.dsh-longtext/<timestamp>_<title>.md and an @ path reference to that file is appended to the composer, leaving the conversation free of the long text itself.

A [DeepSeek Harness](https://github.com/deepseek-ai/deepseek-harness) plugin that adds a **Files** tab to the Conversation View strip — the same level as **Chat** and **Trajectory** — showing the session workspace as a tree with a basic text preview beside it.

Keeps notes as local Markdown files grouped by directory under a root folder you choose, with a sidebar page, AGENTS-style rule files surfaced as writing context, and six agent tools.

Measures what an llm-pi-ai endpoint really accepts — context window from its own model list, output-token limit and reasoning levels read out of its own range errors, image support from a generated test image — then reports declared values that contradict that evidence and rewrites them only after confirmation.

Minimal DSH Web transcript toggle: hide thinking, tool-call, and turn-process rows from the session header while preserving assistant answer text.

Global Quick Actions beside every session-backed composer in DSH. One press sends a preset or your own saved text, with per-action send confirmation.
