Plugins

Let DSH act as a Locus client to deliver a one-stop Unity development experience. The plugin itself does not depend on Locus: you can install the Locus plugin for your Unity project in the settings interface. Features include operating the Unity Editor through Locus’s native broker; semantic analysis and debugging of C# code; and previewing prefabs and 3D models in the sidebar. Its Unity tools can evaluate C# on the editor main thread and edit assets and scene objects.

Registers a battle-tested development delivery rulebook as a skill family - one core skill (clarification, delivery checklist, navigation) plus nine focused skills (layered architecture, evidence-driven debugging, minimal changes, impact-graded verification, migration feature parity, async UI feedback, sizing rules, CLI safety and cleanup, project notes). Only the skills matching the current task are loaded, trivial tasks (small reversible single-file edits) are exempted outright, so each session pays tokens just for the rules it actually uses.

Records browser bugs, freezes expected results, and verifies fixes against a fresh original-code control.

Local dev panel for the DSH web GUI: follow service logs, start/stop workspace programs, debug Java over JDWP, browse and edit workspace files, and search file names. Needs DSH 0.2.0-rc.2 or later; starting or debugging Java programs needs a local JDK and Maven, and starting front-end programs needs Node.

Exposes a stdio MCP server as native DeepSeek Harness tools. Ships with the official Microsoft Playwright MCP preset, so the agent browses through the Edge or Chrome you already have open, with your logins intact; any other stdio MCP command can be configured instead. Host-only, no client bundle, no npm dependencies. To drive your own browser, start Edge/Chrome with remote debugging and allow npx to fetch @playwright/mcp.

Agent-native API client for DeepSeek Harness: Postman-like debugging UI (request tree with context menus and full keyboard navigation, resizable sidebar, layered auto-generated header preview with per-item suppression and constant secret masking), six api_client_* agent tools sharing the same request core, redaction and audit chain with the human UI, Postman Collection v2.1 import with a migration report, environment variables with SecretRef indirection, and a fail-closed SSRF network policy.

HTTP network debugging toolset for DeepSeek Harness: a general-purpose HTTP client with SSRF/private-network protection, per-session request history with replay, response inspection and HAR export - three dsh tools plus a zero-dependency CLI.

Bundles an engineering-methodology skill library as one Cordis plugin: 14 Agent Skills (planning, testing, debugging, review, delivery) registered on ctx.skills for DeepSeek Harness.

Exact-profile control of your real logged-in Chrome browser: an MCP server plus MV3 extension and authenticated localhost bridge for tabs, locators, file injection, media export, and durable scroll capture, with no debug profile or remote-debugging port.

Inspect and manage the live instruction chain and project skills for the current dsh session, with in-place creation and editing — what you see is what the model gets

Local-first failure evidence capsules for DeepSeek Harness sessions

Feishu (Lark) IM bridge for DeepSeek Harness via `dsh plugin add`; one DM user to one persistent dsh session, with full debugging docs.

Adds a top-left Harness/Chat switcher and a web-chat workspace that drives your own logged-in chat.deepseek.com session in a persistent headless browser, with one-click task extraction to a Harness session and results sent back to the web chat. Starts a persistent Chrome or Edge profile with remote debugging on 127.0.0.1:9410 that keeps your chat.deepseek.com login; its /dual-mode routes have no DSH access check and can create Harness tasks from the web chat.

Pick elements on a real Chrome, Edge or ego lite page inside DeepSeek Harness, comment and screenshot them, then insert the annotation as a chat reference chip — the agent receives the CSS selector, page position, comment and screenshot, and edits the front end you are looking at. It launches Chrome or Edge with its own profile and a random local debugging port and injects an overlay into the pages; for ego lite it attaches to the instance you already have open unless DSH_VISUAL_ANNOTATOR_ADOPT_RUNNING=0.

Freezes a six-step repair chain into callable tools — freeze the facts, measure the real shape, minimal repro, single-variable A/B, a judge that must say OK, delivery gate — plus a zero-dependency boot self-check (path drift, missing files, version sync, crash-log freshness), per-item tunables and a rollback ledger that backs up every action.

Amazon product research workbench for DeepSeek Harness: category, brand and follow-seller collectors driven through the local Edge browser, a product library with unified filters, an FBA/FBM/self-operated profit calculator, blue-ocean category scoring with candidate picks, trademark lookup, supplier image search and Excel export. Proprietary software: it installs and starts without a license, but every data call returns 403 until the author issues a device-bound license key. Needs Edge started with --remote-debugging-port=9222 and signed in to Amazon; starts a local backend on port 3088. The separate 智赢 collector browser extension is optional and adds size, weight, trademark and monthly-sales fields.

Appends one short user message before the next step when the model is circling: the same absolute path written three times with no measurement landing in between, the same error episode (tool, target and normalised fingerprint) returning twice, or a write followed by two steps with no measurement — the last one only arms, and the message lands before the next write rather than interrupting reading. A measurement has two states: intent is judged from the tool arguments at call time, and the write streak is cleared only when the result comes back, only for that command directory. A failed test still counts, because it yields the line that is wrong. Hard measurements are `lsp_diagnostics`, `verify`, `run_tests` and `run_test`; `ops_bash`, `bash`, `shell` and `pwsh` count only when the command matches a measurement pattern, so `ls` no longer launders a blind edit streak. Signals fire once per episode, re-arm after a real measurement, and are capped per turn; a successful `present` sleeps the gate until the next write, and subagent sessions are skipped. Generated paths (build output, lock files, logs) are excluded. Error targets are read out of real `file:///` ESM stacks, so two different files never collapse into one episode, and `cd <dir> && cmd` counts as a measurement of that directory rather than its parent. Ships the `stuck-gate` skill at bundled rank 600 (a user-level copy at 400 overrides its wording) plus a read-only observation panel at `/better-debug` reporting firings, sessions covered, the first action after each message across six classes, and how many measurement loops actually closed. The log defaults to `$DSH_HOME/logs/better-debug.log` and is created on first write, so the panel has data right after install. Optional host services are subscribed dynamically, so a host without them still loads the gate. It does not estimate tokens saved, and it does not claim the message caused the change. The panel banner counts only the failures after the most recent load (`log.current`), so one old mount failure no longer reads as "currently disabled". Test suites wait for log conditions instead of fixed delays (test-only change in 0.2.5).

Screen frames, log lines and (on Windows) key/mouse input on one millisecond timeline: record, mark the failing seconds, box the problem on the frame, then hand the agent a keyframe strip, an animated GIF and the aligned log slice.

Controls an already-running NetEase Cloud Music desktop client over CDP (the client must be started with --remote-debugging-port=9222) and searches songs through NetEase's public web API; no API key or extra login, and member-only features use the client's own signed-in account.

Provides 15 Superpowers skills for DeepSeek Harness, covering test-driven development, debugging, planning, and code review.

Ports the obra/superpowers methodology as 14 native DSH skills — brainstorming, writing-plans, executing-plans, subagent-driven development, test-driven development, systematic debugging, parallel agent dispatch, git worktrees, code review, verification before completion and skill authoring — served through the DSH skills registry with their scripts, references and cross-links intact (frontmatter folded into a manifest, prefixes realigned to DSH skill names). Requires DSH session format v4 (official DeepSeek Harness 0.1.7+): the /superpowers slash command declares the producer-owned source kind plugin:dsh-plugin-superpowers.

Runs Superpowers as an agent preset and gives each skill its own subagent model from a Settings table, so TDD, debugging and verification no longer all inherit the parent model.

Drives a Chromium browser you are already running — Chrome, Edge, Brave, Vivaldi, Opera, Chromium, Arc or Thorium — over one long-lived CDP connection, so the remote-debugging approval is asked once instead of per command. Commands for tabs, navigation, JS evaluation, DOM snapshots, clicks, typing, screenshots and CSS/DOM/pixel assertions go over a loopback HTTP route that the agent calls with the shell tool it already has, so no new tools are registered, and the plugin registers its own usage skill with no runtime dependencies.

Browser automation connector: drives the local Edge or Chrome over the DevTools Protocol with zero runtime dependencies — launch a headless throwaway-profile browser or attach to one started with --remote-debugging-port, then navigate, read page text and interactive elements, click, type, and screenshot through 11 agent tools.
