@lucagiftzek/dsh-request-image-cap
限制 DSH 投入模型请求的每张图像的单边像素尺寸（当请求包含多张图像时，Anthropic 拒绝单边超过 2000 像素的图像）。
插件会安装到这里；不确定时保持 web。
npx -y @deepseek-ai/dsh plugin --profile web add github:lucagiftzek/dsh-request-image-cap#a8f702ffc465c4405da6e7a7f7fbf4cc8c7906ea
Request Image Cap 以 @lucagiftzek/dsh-request-image-cap 发布，当前版本为 0.1.0。Plugin Hub 会校验它的 manifest，并保存精确安装来源，便于复现安装结果。
Clamps every image sent to the model to a pixel cap, so many-image requests stop failing.
dsh plugin --profile web add @lucagiftzek/dsh-request-image-cap
# or from GitHub: dsh plugin --profile web add github:lucagiftzek/dsh-request-image-cap
# then restart dsh web
A tall screenshot failing a many-image request, and the capped version
Keep every image DSH transmits inside the provider's per-side pixel limit.
The Anthropic Messages API accepts 8000 px per side for an ordinary request but only 2000 px per side once the request carries many images:
400 invalid_request_error
messages.10.content.5.image.source.base64.data: At least one of the image
dimensions exceed max allowed size for many-image requests: 2000 pixels
Both DSH image gates are area gates:
| stage | knob | default |
|---|---|---|
ingest (dsh-attachment-local) | normalizedImageMaxPixels / normalizedImageMaxDimension | 4 194 304 px² / 8192 px |
request projection (requestImageDimensions) | llm-pi-ai.requestImagePixelBudget | 4 194 304 px² |
A full-page screenshot therefore lands in the store as e.g. 828x5059 (inside
the area budget, far outside the per-side rule) and is transmitted verbatim.
The failure is latent: the same image is fine in a short request and only kills
a long session later, then on every retry, because the bytes are already in the
history.
Wraps ctx.attachments.readImageRequest(ref, policy, signal) (the single seam
every LLM adapter uses to materialise request bytes) and converts a per-side
cap into the area budget that produces it:
maxPixels' = floor(w * h * (cap / max(w, h))^2)
requestImageDimensions scales by sqrt(maxPixels/(w*h)) and floors, so the
long edge lands at or under cap, aspect ratio preserved.
- id: request-image-cap
config:
enabled: true
maxDimension: 2000 # 64..8192
verbose: false # log every clamp
Install from npm: dsh plugin --profile web add @lucagiftzek/dsh-request-image-cap, or from GitHub: dsh plugin --profile web add github:lucagiftzek/dsh-request-image-cap.
dsh plugin --profile web add @lucagiftzek/dsh-request-image-cap
# or from GitHub: dsh plugin --profile web add github:lucagiftzek/dsh-request-image-cap
The package declares dsh.bundle, so it joins dsh.profile.bundles and its own patch
inserts the entry. Override values with a - id: request-image-cap row (config: only, no
second insert) in your profile's cordis.patch.yml. It mounts at boot: restart dsh web
after installing; the log then shows request-image-cap: active, 2000px per side.
A local checkout works too: dsh plugin --profile web add link:/absolute/path/to/dsh-request-image-cap.
Requires Node 22.18 or newer; used on DSH 0.1.5 and 0.2.1 (the seam is ctx.attachments.readImageRequest).
npm test # node --test test/*.test.js
The tests call the real requestImageDimensions of your installed DSH. They find it under
DSH_GLOBAL_PREFIX or the global prefix of the running node; set DSH_GLOBAL_PREFIX if
DSH lives elsewhere.
Proof on the worst object found in a real attachment store:
828x5059 (388 KB) → 327x1998 (79 KB).
The real fix belongs in requestImageDimensions: a route-owned
maxDimension beside maxPixels. This plugin is the local stand-in.

into ~/.dsh/skills/ once, how).All of them are open source and run on DeepSeek Harness 0.2.x (several on 0.1.5 too).

Built by Luca Tzekos, who also makes Job Opportunities API: employer-direct job data with per-field provenance you can verify yourself, free to read and available as an API. If this plugin is useful to you, a star on this repo or a look at jobopportunitiesapi.org is the best thanks.
