Plugins

Lets the AI insert streaming-generated UI into the conversation or a side panel, written in TSX — already one of the model's native languages, so there is no JSON schema to teach it. Rendered without flicker, state kept across frames with no hard remount, and a click in the card driving the next chat turn. Inline is where streaming matters most; the side Canvas is the more agentic shape. Cards get agentic capabilities of their own — run bash, curl, call the model, read and write files.

Multi-threaded downloader plugin for DeepSeek Harness with bundled aria2: probes the target for Range support, then picks aria2 (4 or 8 connections by file size) or falls back to curl.

Windows PowerShell 5.1 skill for downloading large GitHub release assets: it first read-only probes the host (listening local proxy ports, system proxy and env vars, an installed Clash Verge core and its config, curl version), measures KB/s of four routes in parallel (existing proxy, headless-spawned core, public mirrors, direct), runs a short time-boxed concurrency ladder on the winner, then downloads the asset in parallel curl byte ranges and verifies the byte count plus SHA256 against the release digest. Skips the ladder when the asset is under 100 MB or a single connection already reaches 3 MB/s, because concurrency only pays off when a single connection is throttled: measured 6.3x on a throttled node (1,234 to 7,759 KB/s) but 0.72x on a fast one (5,829 vs 4,175 KB/s). Needs no aria2 or 7z, never changes the system proxy, never asks the user for ports or concurrency, reports ASSET_NOT_FOUND with the real candidate names instead of silently picking a different file, and degrades to a size-only check with DOWNLOAD_SIZE_OK_NO_DIGEST when a release predates digests.

HTTP/API debugging toolset: full-control HTTP requests (method/headers/body/auth), curl command parsing and one-step execution, in-session request history with side-by-side response comparison, pagination-aware Link headers, and DeepSeek-branded UI cards (optional dsh-http-tools-ui).

Keeps bulk output out of the conversation: ctk_execute, ctk_execute_file and ctk_batch_execute run code in a child process and return only the conclusion, ctk_index and ctk_search file long material into a local FTS5 knowledge base built on node:sqlite, and a routing gate refuses curl and wget before they execute. Ships ctk_stats and ctk_doctor plus a settings page with a live context-occupancy panel. No third-party runtime dependencies.

A download-progress indicator for the DSH session header: it reads the background-job roster and parses what downloaders already print — curl --progress-bar, wget, aria2, or a JSON progress file — into a progress ring, animated bars, transfer speed and ETA. Jobs that report nothing show as unknown progress instead of being hidden. A finished file opens with one click, or reveals in the file manager. No third-party plugin required; the package ships zero runtime dependencies.

Device-pairing gateway for DeepSeek Harness: by default it listens on 127.0.0.1:3443 over plain HTTP and reverse-proxies the local dsh at http://127.0.0.1:3080, so a loopback-only install works without any certificate. Production, cross-machine and app pairing require TLS: configure tlsCert/tlsKey plus an https publicUrl (self-signed is fine). A fronting Caddy/Nginx may terminate the public TLS, but the gate itself still needs tlsCert/tlsKey and the proxy must connect back over HTTPS. Features TOTP-authorised QR device pairing, username/password login, sliding sessions with absolute caps, device revocation, a WebUI admin panel and audit log, and a reverse proxy with WebSocket tunnelling. First-run setup is completed in the WebUI wizard. Tests: 171/171 unit tests, 29-step e2e.

Durable cross-session memory plus a fetch ladder that survives hostname-keyed blocking. Four tools: memory_recall, memory_save and memory_stats over a plain-JSON fact store at $DSH_HOME/memory/facts.json, plus resilient_fetch which tries plain fetch, then a same-service alias host (Wikipedia only for now), then curl over IPv6 and IPv4 (needs curl on PATH). No daemon, no npm dependency, no network at import time. (1.3.0 shipped a fifth tool, memory_prune; it was withdrawn in 1.4.0 because adding a tool to a running plugin breaks sessions that were opened before it.)

Outbound route pool for DeepSeek Harness. Ships 15 seed routes plus a 20-entry candidate pool covering 7 target kinds (GitHub raw/codeload/main, npm registry, PyPI index, HuggingFace, general). Routes are verified before use: upstream IP lists go through a TLS handshake with full certificate-chain validation (a bare TCP check can be answered locally and report dead IPs as healthy), and failures advance a cooldown ladder of 2/5/15 minutes with the fastest healthy route picked per target kind. Routes are applied by rewriting the URL with one of four rules (prefix, registry, index, host-replace), reaching git, pip, npm, pnpm, gh, curl and wget through three paths: the shell seam (download commands the model runs through the bash tool are intercepted and rewritten automatically; commands wrapped by the pwsh tool, and fetches made by the host itself or the renderer, are not covered), two registered tools the model can call directly (line_pool_status, line_pool_run), and child-process spawn. Multi-line commands keep their line breaks and only the download segment is touched. URLs carrying credentials (user:token@host) are never rewritten, so tokens are not forwarded to third-party mirrors. No global config is modified. A sidebar panel lists every route with latency, failure reason and cooldown countdown, supports per-route retest and enable/disable, and shows live TUN/proxy status from network-adapter and loopback port checks. The candidate pool is re-verified every 24 hours so newly usable routes are added and dead ones dropped. 570 tests, 87% line coverage.

Draggable floating card that follows background jobs: a progress bar and percentage parsed from wget/curl/apt/pip output, elapsed time, ETA when present, and the latest output line.

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.
