What is dsh-click?

Cross-platform native desktop control for DeepSeek Harness — Windows first.

Look at the screen, then act — every click gated, every action audited.

The same run, animated.

Compatibility

| 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 |

What you get

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:

1. Freshness — the action must cite a basedOn observation; the window is re-captured right before acting and the action is refused if the screen changed (pixel-hash check + max-age bound).
2. Approval — ctx.approval gates every action by default; window-title/executable regexes can allowlist specific windows (still audited).
3. Process identity — the owning process's pid and executable path are verified before and after the act; a change refuses the outcome loudly.
4. Audit — observations and actions land in the session log as dsh-click/observed / dsh-click/action events (sanitized, log-only).

model                           harness
  │ screen_read ──▶ observationId (+ elements, pixels)         ← structured text
  │ click {basedOn, target} ──▶ freshness check ──▶ approval ──▶ helper (UIA)
  │                             pixel hash changed? ── refuse + re-observe
  │                             pid/exe changed after act? ── PROCESS_CHANGED
  │ ◀── canonical JSON + audit events (dsh-click/action)

Quick start

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.

Install & uninstall

• git channel (latest main): dsh plugin --profile web add github:PerryLink/dsh-click — the prepare script builds with production dependencies only.
• npm channel (published releases): dsh plugin --profile web add dsh-click.
• tarball channel: pnpm pack in this repo, then dsh plugin --profile web add ./dsh-click-<version>.tgz.
• uninstall: dsh plugin --profile web remove dsh-click (or remove the row from the profile patch).

If pnpm reports ERR_PNPM_IGNORED_BUILDS for this package (esbuild's harmless platform-binary validation), add allowBuilds: { esbuild: true } to your pnpm-workspace.yaml — the dsh CLI prints the exact snippet.

Configuration

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

Tools & surfaces

| 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 & data

• Permissions: mutating actions cross the official ctx.approval seam — 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/observed and dsh-click/action are 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.

Security boundaries

• 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: true unless 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.

Known limitations

• Windows first. macOS and Linux backends are reserved; on those platforms every call fails closed with a clear reason.
• Text-only fidelity. screen_read depends 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); key reports 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 ignorable envelope append with the marker, and envelope-less hosts — 0.1.0-rc.6–0.1.0-rc.8, 0.1.1-rc.2, and 0.1.2-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. Set auditSessionEvents: false to stop audit appends entirely.
