## Compatibility
| Surface | Status |
|---|---|
| Harness | DeepSeek Harness `dsh-v0.1.5-rc.2` (GitHub tag, verified 2026-09-11). Verified 2026-09-11 against the dsh-v0.1.5-rc.2 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 โ act loop over native desktop applications:
- **`screen_shot`** โ 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`** โ the structured observation: the window's accessibility tree (element ids, types, names, rectangles, supported patterns) plus pixel-location hints with colors โ plain text, no image model required.
- **`click` / `type` / `scroll` / `key`** โ window-scoped actions addressed by element id or coordinates. Delivery prefers UIA invoke, falls back to posted window messages โ and **never steals foreground focus**.
- **`app_list` / `app_launch`** โ enumerate running applications and their windows; launch one by name or path.
Every mutating action crosses one safety boundary:
1. **Freshness** โ 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** โ `ctx.approval` gates every action by default; window-title/executable regexes can allowlist specific windows (still audited).
3. **Process identity** โ the owning process's pid and executable path are verified before **and** after the act; a change refuses the outcome loudly.
4. **Audit** โ observations and actions land in the session log as `dsh-click/observed` / `dsh-click/action` events (sanitized, log-only).
```text
model harness
โ screen_read โโโถ observationId (+ elements, pixels) โ structured text
โ click {basedOn, target} โโโถ freshness check โโโถ approval โโโถ helper (UIA)
โ pixel hash changed? โโ refuse + re-observe
โ pid/exe changed after act? โโ PROCESS_CHANGED
โ โโโ canonical JSON + audit events (dsh-click/action)
```
## Quick start
```sh
# 1. install the bundle into your profile
dsh plugin --profile web add "github:PerryLink/dsh-click#main"
# 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 โ 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#main"` โ 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-.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` โ 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 โ 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.6โrc.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:
```yaml
- insert:
- id: dsh-click
name: dsh-click
config:
requireApproval: true
autoApproveWindows: ['^Notepad']
focusFallback: never
```
## Tools & surfaces
| Tool | Read-only | Needs approval | Notes |
|---|---|---|---|
| `screen_shot` | โ
| โ | Returns an `observationId` later actions cite in `basedOn`; image attachment when the model accepts images |
| `screen_read` | โ
| โ | Accessibility tree + pixel hints; element ids are what actions address |
| `click` | | โ
| Exactly one of `elementId` or `(x, y)`; UIA invoke preferred, posted messages fallback |
| `type` | | โ
| Value-pattern elements only; backs up and restores control text on failure |
| `scroll` | | โ
| Element (scroll pattern) or window (posted wheel) |
| `key` | | โ
| Posted key combinations (`"Ctrl+S"`); apps that ignore posted input refuse loudly |
| `app_list` | โ
| โ | Running applications and their visible windows |
| `app_launch` | | โ
| By name or executable path, with optional arguments |
## Permissions & data
- **Permissions**: mutating actions cross the official `ctx.approval` seam โ 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 โ 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 โ allowed or not โ 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 โ 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 โ `0.1.0-rc.6`โ`0.1.0-rc.8`, `0.1.1-rc.2`, and `0.1.2-rc.1` (which cannot stamp the ignorable marker โ the envelope field is retained for stored-log read compatibility only โ and fails closed on unknown types at read) โ get no audit append; the tool results remain the reconstructable audit trail. Set `auditSessionEvents: false` to stop audit appends entirely.
