DeepSeek Harness Plugin

zjsthmjialin/pdf-background-gray-codex-skill#dsh-pdf-background-gray

Stars ★ 1 Category Docs & Rendering Added 2026-08-16 npm dsh-pdf-background-gray

Registers the remove-pdf-background-gray skill for DSH: whitens gray/off-white scan backgrounds in image-based PDFs while preserving resolution, page geometry, and anti-aliased text edges (lossless Flate write-back), via a single Python script (pypdf + Pillow + numpy).

Install

# from npm (prebuilt)

dsh plugin --profile web add dsh-pdf-background-gray

# from GitHub (first run asks for allowBuilds approval — follow the hint, retry)

dsh plugin --profile web add github:zjsthmjialin/pdf-background-gray-codex-skill#path:/dsh-pdf-background-gray

Any plugin you install runs third-party code with your own permissions — it can read your files, use your credentials, and reach the network, and tool approvals don’t sandbox it. GitHub-sourced plugins also run build scripts at install time. Only install sources you trust, and pin a commit (github:owner/repo#sha).
