Cross-platform native desktop control for DeepSeek Harness — Windows first.
Look at the screen, then act — every click gated, every action audited.
Workflow overview: install → open panel → act. The examples below use the real command surface.
| Surface | Status |
|---|---|
| Harness | DeepSeek Harness dsh-v0.2.1-alpha.1 (GitHub tag, verified 2026-09-25). Verified 2026-09-11 against the dsh-v0.1.7-alpha.1 master checkout (full gate chain + profile install smoke). |
| Node | ^22.19.0 || >=24.0.0 |
| Platforms | Windows first (UIAutomation + Win32 input, via a bundled PowerShell helper); macOS/Linux backends are reserved and fail closed with a clear reason |
| Model | Text-only models fully supported (screen_read returns structured text); vision models additionally get screen_shot images |
dsh-click gives the harness a complete observe → act loop over native desktop applications:
screen_shot— screenshot of a window (or the primary screen), downscaled to a configurable bound. With a vision-capable model the result carries the image; otherwise a text description keeps text-only models working.screen_read— the structured observation: the window's accessibility tree (element ids, types, names, rectangles, supported patterns) plus pixel-location hints with colors — plain text, no image model required.click/type/scroll/key— window-scoped actions addressed by element id or coordinates. Delivery prefers UIA invoke, falls back to posted window messages — and never steals foreground focus.app_list/app_launch— enumerate running applications and their windows; launch one by name or path.
Every mutating action crosses one safety boundary:
- Freshness — the action must cite a
basedOnobservation; the window is re-captured right before acting and the action is refused if the screen changed (pixel-hash check + max-age bound). - Approval —
ctx.approvalgates every action by default; window-title/executable regexes can allowlist specific windows (still audited). - Process identity — the owning process's pid and executable path are verified before and after the act; a change refuses the outcome loudly.
- Audit — observations and actions land in the session log as
dsh-click/observed/dsh-click/actionevents (sanitized, log-only).

│ screen_read ──▶ observationId (+ elements, pixels) ← structured text
│ click {basedOn, target} ──▶ freshness check ──▶ approval ──▶ helper (UIA)
│ pixel hash changed? ── refuse + re-observe

│ ◀── canonical JSON + audit events (dsh-click/action)
dsh plugin --profile web add github:PerryLink/dsh-click# 1. install the bundle into your profile
dsh plugin --profile web add github:PerryLink/dsh-click
# or from npm (published releases)
dsh plugin --profile web add dsh-click
# 2. restart and verify the row
dsh --profile web --dump-config | grep -A2 'id: dsh-click'Then ask the agent to look at a window and act — the approval prompt appears for every mutating action:
> Open Notepad, type "hello", then read back what is on screen.
These are the plugin's real entry points; install once, then call one.

All tunables are Schemastery Config fields (changeable from cordis.yml). An id-targeted override replaces the whole row — restate every key you need. cordis.patch.yml documents each key inline.
| Key | Default | Meaning |
|---|---|---|
requireApproval |
true |
Gate every mutating action behind approval; observers never ask |
autoApproveWindows |
[] |
Window-title/executable regexes that skip the approval ask (still freshness-checked and audited) |
auditSessionEvents |
true |
Append dsh-click/observed / dsh-click/action session audit events. The adaptive gate already skips the append on envelope-less hosts (rc.6–rc.8, 0.1.1-rc.2, and 0.1.2-rc.1, which fails closed on unknown types at read); set false to stop audit appends entirely 0.1.2-rc.1 (adapted 2026-09-02): the session envelope keeps its ignorable field for stored-log read compatibility only - Session.append still cannot stamp it, so audit-gate behavior is unchanged. |
focusFallback |
never |
Whether an action may bring the target window to the foreground as a last resort (never / allow) |
imageMode |
auto |
screen_shot rendering: auto (image when the model accepts images, text otherwise) or text |
helperTimeoutMs |
30000 |
Per-helper-call timeout in ms (1..300000) |
maxHelperOutputBytes |
25165824 |
Cap on one helper response in bytes (1024..67108864) |
maxScreenshotSide |
2560 |
Longest screenshot side in pixels (320..7680); larger captures are downscaled |
staleCheckPixels |
true |
Compare a fresh pixel hash before every action and refuse on change |
maxObservationAgeMs |
30000 |
Maximum age in ms of an observation an action may cite (1000..600000) |
maxCachedObservations |
8 |
LRU cap on cached observations (1..64) |
maxElements |
500 |
Cap on accessibility elements per screen_read (1..2000) |
maxTreeDepth |
32 |
Maximum accessibility tree-walk depth (1..64) |
maxTextLength |
200 |
Truncation length for sanitized model-visible strings (16..10000) |
rollbackEnabled |
true |
Back up and restore control text when type fails |
ocr.enabled / command / language |
true / tesseract / eng |
Optional OCR for the screen_find path (probed at mount; degrades to unavailable when tesseract is absent) |
Example override in your profile patch:
- insert:
- id: dsh-click
name: dsh-click
config:
requireApproval: true
autoApproveWindows: ['^Notepad']
focusFallback: never| Tool | Read-only | Needs approval | Notes |
|---|---|---|---|
screen_shot |
✅ | — | Returns an observationId later actions cite in basedOn; image attachment when the model accepts images |
screen_read |
✅ | — | Accessibility tree + pixel hints; element ids are what actions address |
click |
✅ | Exactly one of elementId or (x, y); UIA invoke preferred, posted messages fallback |
|
type |
✅ | Value-pattern elements only; backs up and restores control text on failure | |
scroll |
✅ | Element (scroll pattern) or window (posted wheel) | |
key |
✅ | Posted key combinations ("Ctrl+S"); apps that ignore posted input refuse loudly |
|
app_list |
✅ | — | Running applications and their visible windows |
app_launch |
✅ | By name or executable path, with optional arguments |
- Permissions: mutating actions cross the official
ctx.approvalseam — the plugin never re-implements or bypasses it. The allowlist only ever skips the ask for specific windows; it cannot disable the freshness or process-identity checks. - Data: the plugin stores nothing on disk except the screenshots the attachment store keeps (content-addressed, under the harness's own attachment policy). Observations are cached in memory (LRU, bounded). No network requests, no credential storage.
- Session log:
dsh-click/observedanddsh-click/actionare log-only audit events carrying sanitized window/process facts — titles, paths, and free text are redacted and length-capped before they are written or shown.
- Observe before act, every time. Actions must cite a fresh observation; a changed screen (pixel hash) or an expired observation is refused with a model-readable reason demanding re-observation.
- Approval is the default.
requireApproval: trueunless you explicitly opt specific windows in; every action — allowed or not — is audit-logged. - No foreground stealing. The helper never brings a target window to the foreground (
focusFallback: 'never'by default); input is delivered through UIA or posted messages so background windows are not disturbed. - Process identity is re-verified immediately before and after each action; a mid-act process swap fails the outcome (
PROCESS_CHANGED). - Sanitized output. Control characters are stripped, tabs collapse, credential-shaped values (keys, tokens, JWTs, bearer headers) are redacted before anything reaches the model or the log.
- Fail closed. Unsupported platforms, a missing subprocess service, or an unavailable helper refuse every call loudly — profiles keep booting everywhere.
- Windows first. macOS and Linux backends are reserved; on those platforms every call fails closed with a clear reason.
- Text-only fidelity.
screen_readdepends on the application exposing UIAutomation; apps without an accessible tree yield pixel hints only. Coordinate clicks remain available. - Posted-input apps. Some applications ignore posted window messages (games, some Electron surfaces);
keyreports this honestly instead of pretending success. - Session audit on envelope-less harness builds. The audit events ride an adaptive gate: hosts that know the vocabulary append plainly, hosts with the
ignorableenvelope append with the marker, and envelope-less hosts —0.1.0-rc.6–0.1.0-rc.8,0.1.1-rc.2, and0.1.2-rc.1(which cannot stamp the ignorable marker — the envelope field is retained for stored-log read compatibility only — and fails closed on unknown types at read) — get no audit append; the tool results remain the reconstructable audit trail. SetauditSessionEvents: falseto stop audit appends entirely.
