Plugins

Load testing with Grafana k6: smoke-test first, then run scripts and read percentiles from the JSON summary.

Enhanced SSH ops: connectivity testing, remote ls, ssh-config import, known_hosts fingerprint checks and multi-host exec.

Human-in-the-loop tools (`human_task` / `human_task_ready_check`): pause the agent until the user performs a real-world action or returns an observation (GUI operation, game testing, visual verification, hardware checks), gated by session consent and an AFK presence check, returning a structured JSON result via a web task dialog.

Test-stability tools: repeatedly run vitest/jest/pytest/node:test suites, classify flaky cases, keep history, maintain a quarantine manifest and health self-check.

Contract regression harness for plugin authors: a scripted LLM adapter drives the real pipeline in isolated child processes with session-event assertions (load/contract/behavior/fault layers); zero API key, CI-ready.

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.

Structured test runner tool (test_run): auto-detect Vitest/Jest/pytest/node:test, run tests, parse failure summaries for the model.

DeepSee: DeepSeek Harness vision, multi-model routing, and Gemini visual self-checks before delivery

Generates DSH host-side plugin skeletons — tool registration, an approval hook, a dsh.bundle manifest and three test layers — and registers a plugin_kit_new tool so the agent can scaffold a plugin from inside DSH without a shell.

Postman-style HTTP workbench in the Harness Web GUI: collections and environments with {{var}} substitution, a request builder covering method, params, headers, body and auth, a response inspector, cURL import and export, and a CDN origin probe that fetches the same URL twice so a deleted file can be told apart from an edge cache. It also exposes an http_request_desktop agent tool that shares the panel send path, so a request debugged in the panel can be replayed by the agent. Zero runtime dependencies; state lives in $DSH_HOME/postman-desktop/store.json.

Model quality testing for DeepSeek Harness Desktop with a question bank, manual and scheduled checks, saved responses, human reviews, and model attribution. Install it into the desktop profile: the shared Go backend is started only by the desktop app, and a web profile can only view an already-running desktop backend.

Brings the third-party deepseekbase.com index into DSH: eight tools and five DSHIO standard skills (from the @liangjiehappy/dsh-dshio dependency). Search 8,400 plugins with real sandbox install verdicts and risk levels (including red-line warnings where credential access meets network), submit a plugin for a four-stage sandbox test from the conversation, read the verdict, check the remaining free quota, and run a clause-by-clause DSHIO/T 10 conformance check. The skill text is fetched from dshio.org at startup and replaces the bundled copy, so updates need no reinstall. Network: HTTPS to deepseekbase.com and dshio.org, plus an npm registry lookup before a test is submitted; no file reads or writes, no credential access, no shell.

Records a session as a run, replays it in an isolated workspace copy with another model or prompt, diffs the two trajectories side by side, aggregates runs into a task × variant matrix, and gates regressions with task assertions and a CI exit code.

A five-stage engineering loop for agent-built projects — spec, build, verify, ship, learn — with one artifact and one gate per phase, so an agent always knows the single next action. Role policy, project templates and deployment sit behind explicit ports: swap the implementation without rewriting the loop. Its scaffold generator lays out the internal layers of a project — `init --layout {none,webapp,service,plugin} --stack {python,node,none}` — from nine layers sampled out of three unrelated production projects: entry docs, an OpenSpec plan face, a spec truth layer (INDEX, one file per domain, TESTING, CONSTITUTION), a wiki split into knowledge / progress / runbook, the six `.agents/` slots, server+web, scripts/deploy/config, tests+e2e and a gitignored out/. Non-none layouts also gate the directory contract and compile every source root. Ships a Python CLI (init/next/check/ship/new) plus a local command adapter and an SSH/systemd adapter with release directories, an atomic current/previous switch, a deploy lock, a commit-versioned JSON probe and automatic rollback on a failed probe; bootstrap and teardown provision and remove the unit and the reverse-proxy block idempotently and refuse to delete a root they did not create. Includes a runnable example workspace and a skill that keeps the agent on one phase at a time. Requires Python 3.10+ and PyYAML; remote deploys need SSH access, rsync, systemd and Caddy on the target.

Agent application development evaluation skill (skill bundle) for DeepSeek Harness: offline/online suites judged from audit side effects, baseline diff with zero tolerance for safety regressions, and mutation tests proving the evaluators themselves catch regressions. Framework-agnostic - needs a callable chat endpoint and queryable tool-call records. DSH host compatibility is deliberately undeclared.

White-box testing workflow skill for embedded C: host-side stub harness, wb.py test driver with gcov coverage gating, and a control-logic study handbook template.

Runs project check commands itself and records the real exit codes, pins the result to a git or file workspace fingerprint, expires the evidence when the tree changes, and reminds the agent to verify before claiming completion.

A run_tests tool that turns a failing test run into precise context instead of a raw dump. It detects the runner (pytest, jest, vitest, cargo, go, npm), extracts the file, line and assertion of each failure, and stops the loop when failures with an identical signature repeat. Output is decoded so Windows-encoded and non-Latin assertion text stays readable.

Test work framework for DSH that scaffolds a product, module and version directory tree, registers seven test_framework_* tools and four runtime skills, and adds a prompt-level gate that reports which requirement-document splits, versions, related documents and environment credentials are still unrecorded before testing starts. Requires the playwright MCP server (no fallback).

Project Development Mode preset plus an in-chat development board for DeepSeek Harness: the lead conversation clarifies requirements and delegates to an Agent Team, and the floating board tracks each user change request through dispatch, execution, testing and acceptance with 7 board tools.

A fork of Microsoft's official .NET/C# skills for AI coding agents, additionally packaged as a DeepSeek Harness plugin — covering development, testing, diagnostics, migration, and AI integration.

Knowledge-point notebook for DeepSeek Harness: turns a Markdown notes folder into a card canvas — folder = chapter, file = section, body = knowledge points — with masked-answer questions for self-testing, KaTeX formulas, Mermaid flowcharts, a mind map view and in-panel editing.

Ships a skill for verifying a change with the cheapest check that still yields a definite answer: an L0-L3 cost ladder from static checks to a single suite, condition polling with a timeout instead of fixed sleeps, assertions that can actually fail, and durations that are measured rather than remembered. The package also carries the two zero-dependency Node tools the skill calls - wait-until.mjs (poll a command, a file, or a port until it is ready) and measure-runtime.mjs (wall-clock timing for any command, plus a segmented timer for library use).

API regression and acceptance workbench: snapshot the responses of the endpoints you register before the agent edits the backend, rerun them all after the edit, and review a structured field-level diff (status codes, added and removed fields, numeric old → new values with the delta) beside the captured source diff, accepting each endpoint one by one before exporting a Markdown or single-file HTML report.
