DeepSeek Harness Plugin

yanzhaohui1999/dsh-perf-hud

Category Development & Runtime Added 2026-10-18

Client-side performance HUD and always-on recorder for DeepSeek Harness: FPS and worst frame, long tasks with four-leg attribution (React fiber / subtree / DOM writes / scheduler), per-plugin callback rate and sync time, DOM growth and writers, JS heap, host event loop and link RTT, plus a night-watch recorder that keeps the worst stalls and exports incident packs for replay.

Install

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

dsh plugin --profile web add github:yanzhaohui1999/dsh-perf-hud

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 — pnpm blocks those until you allow them, so an install can stop with ERR_PNPM_GIT_DEP_PREPARE_NOT_ALLOWED or ERR_PNPM_IGNORED_BUILDS; dsh prints the exact key to add under allowBuilds in your profile’s pnpm-workspace.yaml, and the install works on the next run. Allowing a build is a trust decision: only install sources you trust, and pin a commit (github:owner/repo#sha).
