DeepSeek Harness Plugin

Category Sessions & Messages Added 2026-11-10

Replaces the dsh compaction backend with a Codex-style window reset: the checkpoint is a handoff assembled from the session log by code, not a model-written summary, so a reset costs no summarization calls. A task ledger with a two-check gate keeps intent, next steps and the files still in play across resets, and a new_context tool lets the model reset on its own. Re-declares the four built-in agent presets (standard, ptc, minimal, cordis) exactly as shipped in dsh 0.2.2-rc.1, so re-run sync-presets.mjs after a dsh upgrade; idle cache keepalive is on by default and sends real requests that use quota (keepalive: false turns it off).

Install

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

dsh plugin --profile web add github:niszhum/dsh-compact-codex

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).
