Find the right DSH plugin
for your next workflow

Plugin-combination analysis for the DeepSeek Harness: dependency trees, conflict detection, risk scoring with prediction, visualization, and combination simulation.

Offline diagnostic for DSH: 19 checks across env, profile, and session state, with a settings "Doctor" panel and a read-only JSON API.

Discovers installed DSH plugins with tags, overlap and compatibility detection, one-click enable/disable, failure diagnosis, and update checking.

Session-bound persistent TypeScript REPL for DSH PTC mode: bindings and imports stay live across run_code calls, edit_run_code replaces one line without resending the block, module import/export syntax is adapted via AST rewriting, and durable bindings are restored from the session journal after a cold restart.

Cadence SKILL (Virtuoso Lisp) assistant for EDA engineers: official-doc-anchored API lookup (3557 entries across 5 IC6.1.8 manuals, signature confidence levels, never invents APIs) plus zero-execution static analysis driven by a lexical depth coordinate system — iterator-safe deletion with position-sensitive copy() protection, printf placeholder/argument reconciliation, in-loop nth O(N^2) detection, deprecated APIs with page refs, dangerous-intent interception and CIW error-log triage. Host half has zero third-party dependencies.

Auto-approval agent for DSH permission requests: rule layer (denyAlways/allowlist) plus Hermes Pro semantic adjudication with quick-fail retries, fail-closed to human when Hermes is unavailable, rejection feedback returned to the requesting session, and approve tasks enqueued into the task queue with a shared busy mutex.

Mandatory cross-review for design proposals and lessons-learned: auto-detects design doc writes and enqueues them (tier=review) into the task queue, delivers the external reviewer verdict back to the initiating session, and appends approved preventive measures to OPS-GUARDRAILS.md (append-only, conflict-checked).

Hands DSH reset requests to an external ops agent via a versioned JSON protocol: preflight snapshot, pre-restart maturity gate (no pending approvals, free disk, cooldown), restart, health check, and interrupted-work recovery, with the result delivered back to the requesting session.

Tiered task queue as the single source of truth for DSH↔Hermes work (reset > approve > review): enqueue tools for all submission paths, lease/claim model with concurrency 1, priority aging against starvation, atomic busy mutex, and a Hermes-side consumer (cron */1 + monitor gating) that drains tasks, writes review-handoff requests with single-slot checks, and invokes the reset agent.

Bridges the harmonyos-dev-mcp Python MCP server into DSH: HarmonyOS device discovery, build/install/run/uninstall, UI automation (click/input/keys/swipe/screenshot), E2E UI-tree inspection, and log/crash analysis as 18 mcp__harmonyos__* tools.

Windows system-tray launcher for DeepSeek Harness Web: start, stop, restart, open the Web UI, tail logs, live status icon, and a launch-at-login toggle.

Ship a project to Cloudflare and publish your plugin to npm — the first deploy needs no cloud account, and credentials never reach the model.

Plugin health checks: manifest protocol / patch format / build traps, zero-dependency and read-only.

Frame-level scan diagnostics for session files (torn/corrupt/empty detection).

Plugin template repo (based on the official turtle-ui repo).

An MC-Fabric-style hook processor.

Loads Claude-style plugins into DeepSeek Harness (dsh): discovers skills, commands and optional SessionStart hooks from Claude plugin directories, with hot command reload and uninstall cleanup.

Freshness gate for the agent's test, typecheck, lint and build claims: each verification run becomes a receipt on tools/post-execute, file edits are tracked, and on agent/turn-stopping a claim whose latest receipt is stale, failed or has no readable result steers one more step naming the receipt and the files edited since.

Performance profiling and LLM cache diagnostics for DeepSeek Harness — context engineering, latency profiling, and cache behavior reports.

Read-only runtime management panel for the official DSH MCP client: connection status, registered tools, errors, and reconnect counts through the /mcp command and a Settings tab, with sanitized display and enable/disable patch suggestions.

Exports the session event stream to OpenTelemetry OTLP and Langfuse as sanitized, buffered traces and metrics, off by default.

Runtime-switchable model output styles with Claude Code outputStyles parity, plus the output.render.* presentation protocol: a /style command, per-session persistence, systemPrompt injection, six built-in styles, a web picker, and a renderer registry with per-session/per-tool rules and /export.

Multi-dimensional quality scoring for DeepSeek Harness plugins that scores a repo or npm package across install success, maintenance activity, documentation completeness, security scan, and protocol compliance using real CLI evidence, and produces a JSON or Markdown leaderboard report.

Runs isolated install-and-smoke test drives for DSH plugins in throwaway profiles, returning structured pass/fail records and batch matrices without touching your real profile.
