## Install & uninstall
- **git channel** (latest `main`): `dsh plugin --profile web add github:PerryLink/dsh-draw` — the `prepare` script builds with production dependencies only.
- **npm channel** (published releases): `dsh plugin --profile web add dsh-draw`.
- **tarball channel**: `pnpm pack` in this repo, then `dsh plugin --profile web add ./dsh-draw-.tgz`.
- **uninstall**: `dsh plugin --profile web remove dsh-draw` (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.

## What is dsh-draw?
Unified static-image generation routing for DeepSeek Harness.
One tool, many engines — health-aware fallback, durable results, counted usage.
*Workflow overview: call → plugin → result. The examples below use the real command surface.*
## Maintenance status: 🧊 FROZEN
> **Frozen on 2026-10-05. No new features.** This package still works, and it is not retired — but it no longer receives feature work. Only a genuine breakage will be fixed.
Maintainers treat this capability as one where **the ecosystem has converged on a more widely adopted implementation**, so effort has moved elsewhere. The comparison below was measured on 2026-10-05 and is recorded so nobody has to redo it.
| | package | weekly downloads |
|---|---|---|
| **this package** | `dsh-draw` | 973 |
| more widely adopted implementation | [`dsh-image-gen`](https://github.com/shanliuling/dsh-image-gen) | **7,216** |
| another alternative | `@goodandready/dsh-image-gen` | 4,822 |
**Why it is the mainstream choice.** `dsh-image-gen` provides Gemini, OpenAI, Seedream, DashScope and a local ComfyUI in one plugin.
**Compatibility.** declares no dsh peers, so the compatibility guard never blocks it.
👉 **For new work, dsh-image-gen is the mainstream choice.** Existing installs keep working unchanged; nothing is being removed.

## Comparison
measured 2026-10-05 · from the README's FROZEN maintenance table (npm weekly downloads)
## Compatibility
| Surface | Status |
|---|---|
| Harness | DeepSeek Harness `dsh-v0.2.1-alpha.1` (compat declared for `0.1.5-rc.2`) |
| Node | `^22.19.0 \|\| >=24.0.0` |
| Engines | Any OpenAI-compatible images endpoint; presets for OpenAI Images (`gpt-image-1`) and Zhipu CogView (`cogview-3-flash`) |
| Surfaces | Host `image_generate` tool + web result card + Plugins settings tab |
The browser half rides the cordis `Context` and the published client packages (`dsh-client-ui-slots`, `dsh-client-ui-settings`, `dsh-client-ui-tool`, `dsh-client-locale`, `dsh-client-connection`); it no longer depends on the removed `dsh-client-runtime` package (the tool-call block is read through a local structural contract), so the client surface also lines up with `0.1.2-rc.1` hosts.
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. Verified 2026-09-06 against the dsh-v0.1.7-alpha.1 master checkout (full gate chain + profile install smoke).
0.1.6-alpha.2 (adapted 2026-09-18): `Session.append`'s third parameter exists only for surface-eligible event types and is a `SurfaceIntent`, never an `ignorable` envelope, so `draw/generated` (a non-surface type) is still not written on this line — quota is counted in memory per session and resets when the session restarts, exactly as the "Quota durability" note below describes. Verified 2026-09-18 (dual typecheck rulers + the full suite + self-contained/artifacts/readme gates).
0.1.7-rc.2 (adapted 2026-10-04): the client `tool.call.toolview` contract split its owner into three stages (`preparing` / `start` / `result`), and a keyed card is now dispatched while the arguments are still streaming. The result card therefore also renders the in-flight row for those earlier stages — an occupied keyed slot never reaches the host's own generic row, so answering a prepared stage with nothing blanked the line for the whole streaming window. Nothing else changed: the settled card, the accounting line, and regenerate behave exactly as before. Verified 2026-09-23 (dual typecheck rulers + the full suite + the new host-contract gate).
## What you get
`dsh-draw` gives the harness one unified `image_generate` tool with standard parameters (`prompt`/`size`/`count`/`quality`/`style`/`engine`) that are translated per engine:
- **Multi-engine routing** — a config-driven chain (OpenAI Images, Zhipu CogView, or any OpenAI-compatible endpoint) walked top-down with **health-aware fallback**: consecutive failures push an engine into cooldown, and the next healthy engine serves the call.
- **Durable results** — generated images are saved as workspace attachments (content-addressed, under the harness's attachment policy) and returned as canonical file references.
- **Quota accounting** — per-session caps on generation calls and image bytes, folded from the durable session log and enforced before engine spend and before storage.
- **Credentials as references** — engine API keys are environment-variable names resolved per call through the official `ctx.credentials` seam; literal keys are never stored in configuration and never logged.
- **Web surfaces** — an in-conversation result card (images, engine, quota, one-click regenerate) and a Plugins settings tab (engine chain, credential status, probes, quota limits).
```text
model harness
│ image_generate {prompt, ...} ──▶ validate ──▶ quota check ──▶ router
│ openai ──(fail)──▶ cogview ──▶ images
│ ◀── canonical JSON + image blocks (durable attachment refs)
│ └── draw/generated session event (quota + audit)
```
## Quick start
```sh
dsh plugin --profile web add github:PerryLink/dsh-draw
```
```sh
# 1. install the bundle into your profile
dsh plugin --profile web add github:PerryLink/dsh-draw
# or from npm (published releases)
dsh plugin --profile web add dsh-draw
# 2. provide the engine keys as credential references (environment variables)
# OPENAI_API_KEY and/or ZHIPU_API_KEY — never in the profile patch
# 3. restart and verify the row
dsh --profile web --dump-config | grep -A2 'id: dsh-draw'
```
Then ask the agent to draw:
```
> Draw a 1536x1024 landscape of a lighthouse at dusk, vivid style.
```

#### Brief examples
## 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 |
|---|---|---|
| `engines` | OpenAI + CogView presets | Ordered engine chain, walked top-down with fallback; each entry: `id`, `baseUrl` (no credentials), `model`, `apiKeyRef` (env-var name), `provider` (`openai`/`replicate`/`fal`, default `openai`), `enabled`, `sizeMap`, `qualitySupported`, `styleSupported`, `responseFormat` (`b64_json`/`url`), `imageMediaType` |
| `defaultEngine` | `openai` | Engine id the router prefers; must name a configured engine |
| `requestTimeoutMs` | `120000` | Per-generation HTTP timeout (1000..600000) |
| `maxImagesPerCall` | `4` | Cap on images one call may produce (1..10) |
| `maxPromptLength` | `4000` | Prompt length cap in characters (1..32000) |
| `maxGenerationsPerSession` | `200` | Per-session generation-call cap (1..100000) |
| `maxBytesPerSession` | `209715200` | Per-session image-byte cap (1048576..4294967296) |
| `failureThreshold` | `2` | Consecutive failures before an engine enters cooldown (1..10) |
| `cooldownMs` | `60000` | Engine cooldown after the threshold trips (1000..3600000) |
Example override in your profile patch:
```yaml
- insert:
- id: dsh-draw
name: dsh-draw
config:
defaultEngine: cogview
maxImagesPerCall: 2
```
## Tools & surfaces
| Surface | Notes |
|---|---|
| `image_generate` | Standard parameters; returns canonical JSON (engine/model/size, image references, quota, fallback flag, attempts) plus image content blocks |
| Result card (`tool.call.toolview`, key `image_generate`) | In every stage of the call: an in-flight row while the arguments stream, then images, engine/quota line, and one-click regenerate once it settles (full drawer path: quota + routing + audit) |
| Settings tab (Plugins → Image generation) | Engine chain, credential status, set/remove API keys (credential references), connectivity probes, quota limits |
## Permissions & data
- **Permissions**: the plugin makes outbound HTTPS calls to the configured engine endpoints only; every other surface is read-only. The settings tab's only writes are credential set/remove calls on the official `ctx.credentials` seam.
- **Data**: generated images are saved through the official attachment store under the harness's own attachment policy. Quota usage is folded from the `draw/generated` session events, plus the in-memory fallback ledger on hosts that cannot log those events — nothing else is stored.
- **Session log**: the `draw/generated` event records engine, model, standardized request, byte totals, and attachment ids — the audit facts, never the API keys. The event is appended only when the host knows the type or honors the `ignorable` envelope (probed at mount); on rc.6/rc.7 hosts and the `0.1.2-rc.1` line (whose `Session.append` cannot stamp the marker and which fails closed on unknown types at read) the payload goes to the in-memory fallback ledger instead, so generating images can no longer make a session refuse to reopen.
## Security boundaries
- **Credential references, never literals.** `apiKeyRef` names an environment variable; a `baseUrl` embedding credentials fails the load loudly.
- **Sanitized display.** URLs, probe notes, and error text are redacted (userinfo passwords, credential query values, bearer tokens, JWTs) before any display or log.
- **Quota before spend.** Generation and byte caps are checked before engine calls and before attachment storage; exhausted sessions fail fast without spending engine credits.
- **Fail loud, fall back deliberately.** Malformed responses surface as structured errors; a failing engine is skipped after its cooldown threshold, and a fully exhausted chain returns the complete attempt record instead of pretending success.
## Known limitations
- **Image models only.** No video, audio, or edit endpoints; no vision understanding.
- **Engine compatibility.** Three vocabularies are supported through the provider seam: `openai` (the `POST /images/generations` shape), `replicate` (prediction create + poll), and `fal` (the `fal.run` queue). Provider-specific extras beyond `prompt`/size/count (e.g. seed, scheduler) are out of scope.
- **Cost awareness is structural.** The plugin counts calls and bytes but does not know engine pricing — pair with `dsh-budget` for cost governance.
- **Quota durability on rc.6/rc.7, 0.1.2-rc.1 and 0.1.6-alpha.2.** On hosts whose session log cannot carry `draw/generated` (static event whitelist, no `ignorable` envelope; `0.1.2-rc.1` cannot stamp the marker and fails closed on unknown event types at read; on `0.1.6-alpha.2` the append's third parameter is a `SurfaceIntent` for surface types only, so a non-surface event cannot be marked), quota stays exact for the live session from the in-memory fallback ledger but resets on restart; durable accounting resumes on hosts with a plugin event surface. The first refused commit warns once, so a degraded session is visible instead of silent.
## Development
```sh
pnpm install # node ^22.19 || >=24
pnpm run typecheck # tsc: src + tests against the local harness checkout
pnpm run typecheck:ci # tsc against the published 0.1.7-rc.2 faces (no paths)
pnpm test # vitest: 19 spec files (scripted transport, real Context/Session/ToolRuntime)
pnpm run build # tsc declarations + tsdown bundles (lib/)
pnpm run verify:self-contained # dependency specs resolve from the registry
pnpm run verify:host-contract # the host tool-view contract still matches what this plugin declares
pnpm run verify:artifacts # host ESM face + typert manifest + browser bundle + config files
pnpm pack # the published tarball
```
