Real-time LSP diagnostics loop: lsp_diagnostics / lsp_workspace_errors / lsp_hover tools over headless stdio language servers (TypeScript/JavaScript + Python), plus an auto-injected post-edit diagnostics delta wired to the harness fs/observed event — Cursor-style edit → diagnostics → fix for dsh agents.

DeepSeek Harness plugin for organizing AI discussions into research topics, traceable knowledge cards, and reusable research materials on an interactive graph

A focused end-user QA surface backed by native DeepSeek Harness sessions

P0–P4 deterministic-first permission gate with permissive tier, learning sedimentation and approval-history UI; hard-deny credentials and protected paths, auto-allow internal read-only tools.

DSH markdown preview: clicking a markdown document in the conversation opens a rendered preview panel docked to the right of the chat.

Compares existing DSH sessions or runs controlled A/B trials between agent presets, showing aligned timelines, paired metric deltas, explicit success checks, and exportable reports.

Drag or paste files into the Web composer with one image-and-file preview rail; native PNG/JPEG/WebP/GIF keep the image attachment path, while other files reuse a matching local path or stream to Host staging and become @ references only at send time. Includes browser media/PDF and bounded text previews; Office and archives show identity cards, and unsent file entries are page-local.

Live request metadata minimization for DeepSeek Harness, covering the native DeepSeek provider with WebUI settings.

Git-native, auditable long-term memory for AI agents

Self-evolution actuator: consumes problem tickets mined from session logs, synthesizes skill candidates (zero-code tiers by default) behind an eval gate with hold-out canaries, then promotes to project .dsh/skills with human confirm and deterministic rollback.

Cross-app project memory for DeepSeek Harness with role-separated writeback, a visual knowledge workspace, confirmed corrections, session controls, local Writer and organizer settings, and an account-free Windows local installation preview.

Session health-check: mechanically mines session logs into structured problem tickets (retry loops, tool-error clusters, interrupted turns, token waste) over the official session-query seam; works standalone.

Governs multi-model access, monthly credits, manual/quality/credit/auto routing, failure rerouting, and usage auditing for DSH.

OpenAI-completions-compatible adapter for custom gateways (vLLM / LM Studio / self-hosted proxies): always role:"system", thinking driven by the model config, Qwen-style response split, and vision-model image input (single / multiple).

Conversation-level multi-agent workbench for editable task planning, real child-session observation, plan-versus-runtime comparison, and evidence-backed recovery previews; tested with DSH 0.1.1-rc.2.

Turns DSH conversations into reviewable community feedback and, after confirmation, submits it to the official DeepSeek Harness Discussions.

Consent-bound one-turn voice preview for DSH Web with a credential-free local synthetic demo, optional Qwen Audio, exact Session isolation, and explicit transcript-to-draft handoff without automatic submission.

Compare DeepSeek Harness, Codex, and Claude Code instruction surfaces for the same workspace.

Piano performance plugin: ask the agent to play a piece and it renders on a Canvas2D grand piano with real Salamander Grand samples, an immersive stage, and an interactive 88-key keyboard.

Model visibility manager for DeepSeek Harness: hide or show any model in the conversation model selector from a dedicated settings page. Per-model switches, search, provider-level batch actions, reset-all. Zero intrusion - writes only its own hidden list, never the provider config; hiding a model in use never interrupts a running session.

Terminal-native frontend for the DeepSeek Harness plugin ecosystem

Live Spring Boot error HUD with opt-in AI diagnosis for DeepSeek Harness

Bidirectional RPC between DSH Host and Client through the native Connection and Typert Gateway, with targeted peer calls, cancellation, and connection lifecycle handling.

Escaped, theme-aware HTML code-block rendering service for DSH Web plugins, built on structured syntax-highlight tokens with source line-ending preservation.
