Control plane for the harness's own Agent Teams: members are ordinary independent sessions created through the same seam the GUI uses, each with its own model, so they open and continue like any other conversation while a sidecar roster and task board coordinate them. Task entries carry a definition of done, a member's completion is submitted and waits for the Lead's review, and availability tells idle apart from awaiting-review or a failed last turn. With delegationEngine=auto it uses independent sessions, continuable subagents, or the kernel roster depending on what the composition provides.

AI UI automation via Midscene — android_ui and web_ui tools that tap, type, query, and assert on a real Android device or an already-running Chrome through the ctx.midscene seam.

Runs the agent's filesystem, bash and PTY terminals inside a Docker container by providing the `ctx.fs` and `ctx.subprocess` seams, so cwd, environment and background processes survive a harness restart.

Metaso (秘塔AI搜索) search & reader providers for the web seam: web_search returns page summaries, web_fetch reads full-page markdown, multi-scope search (webpage/document/paper/image/video/podcast).

Registers a wrapper provider that gives delegated subagents their own LLM route — one-off spawns through provider.start, Agent Teams members through a hook on startActivation — while the main agent keeps its model. Ships a Settings section for picking that route, a per-expert override file, a capability flag reporting which seams the hook caught, and a readiness record written at mount.

Niubash-only shell executor and Bash-dialect teaching for DeepSeek Harness (dsh 0.2.0-rc.2, and the 0.1.7-rc.x line it shares its shell seam with): every ctx.shell execution runs as `niu -c`, PowerShell/cmd/WSL/nu handoffs are refused, PowerShell habits a

Tavily-backed search provider for the DeepSeek Harness web capability seam (ctx.web) — replaces the official web search with multi-key balance-aware rotation, manageable from the DSH web settings (Plugins → Plugin configuration).

Firecrawl-backed search and fetch providers for the DeepSeek Harness web capability seam (ctx.web)

OpenTelemetry traces backend for the DeepSeek Harness telemetry seam: folds agent session events into OTLP span trees

Unified web search for the DeepSeek Harness seam (ctx.web): DeepSeek (official), Tavily, and Brave backends with an in-browser selector

Unifies every DSH extensibility seam behind one declarative DSL: a runtime `fabric` service, `fabric_extend`/`fabric_inspect` tools, and a capability-graph settings page.

Native per-workspace memory on the harness's own seams: facts and a bounded always-on profile on the storage-domain JSON unit, approval-gated writes with `(sessionId, seq)` citations, deterministic recall plus session-query FTS over past sessions — no external server, no custom SQLite.

macOS Keychain credential provider that replaces the local-file provider and uses a signed, notarized universal helper.

Command Code Go provider adapter for dsh: scan the Go-plan model catalog dynamically and serve /alpha/generate through the harness LLM seam

Decision layer for dsh: provider-agnostic typed judgments (Jev first) behind tool guardrail, model routing, result judging, and machine approval seams

One prompt row carrying two independently switchable halves. Identity: a fixed self-reference restated at the head, at the tail after every other section, and in the runtime snapshot, with an instruction to treat contradicting claims as stale cache. Discipline: ten rules, each paired with the condition a reviewer checks — external evidence before claiming done, change face equal to review face, correctness from named call points rather than timing, one source of truth, extension through the registered seam, runtime validation only at real boundaries, loud failure instead of silent skips, orthogonal outcomes reported separately, tests through the delivered entry point, and answer shape (conclusion first, length set by the change).

Devin CLI inside DeepSeek Harness: a `devin` delegation tool, a /devin command, and a `devin` LLM provider route — all over the ctx.subprocess seam.

File-defined command hooks across the session, prompt, tool, permission, Stop and PostCompact seams, with an approval-only GUI: no unapproved command runs, and approval binds the exact definition, canonical working directory and pinned watchFiles. Commands run as the DSH OS user without a hook sandbox, so the trust ledger is explicit.

Local art pipeline for DSH: drives the locally installed SD WebUI and ComfyUI backends through ten image_* tools and an Art Studio sidebar panel with an embedded ComfyUI canvas, post-processes with the Python shipped with those installs (rembg cutout, Real-ESRGAN upscale, seamless tiling), and writes Godot-ready assets with res:// paths once a project root is set.

Deep-space theme for the Harness Web GUI: two fully designed light and dark palettes over a seamless cross-dissolve nebula wallpaper, plus a model probe that reports which configured models actually answer and their real context window.

Gives DSH the full 33-tool browser surface (ctx.browser seam -> a self-hosted headless moli browser over CDP: one 127.0.0.1 daemon with Bearer-token auth, request-path whitelist and WebSocket rewriting, no root/GUI/Electron needed; single-engine moli serve with auto LD_LIBRARY_PATH/FONTCONFIG_FILE injection and a persistent profile dir for logins), plus a web panel — a real page you can click, scroll and type in, operation/console/network logs with one-click cleanup, a customizable window (border color, transparency, glass, fit-to-picture with no black bars, top-inset and self-centering) and an adjustable page size (1920x1080 by default) — plus a collapsed pill that can be dragged to any spot on the screen (free position), a live view that auto-resumes when you switch back to the web tab, and a 1920px default max edge for the live frame — and two bundled skills (browser, browser-runtime) served through the plugin built-in skill provider, so the skill centre lists them as system-level by default without writing into $DSH_HOME/skills.

TinyFish-backed search and fetch providers for the DeepSeek Harness web capability seam (ctx.web) — $0 SERP and page extraction, direct or via Monid.
