Automatic context compaction: a background observer distills early history into summary blocks, and when usage crosses the trigger line the engine commits whole blocks until it is back under the target line, with no model call on the commit path. Blocks merge into higher tiers as material runs out, and decompress or search_context reads any block back at its original length. The background observer spends model tokens: it uses the session's provider and model unless you pick another, with up to 10 distillations at once by default.
Install
# from GitHub (first run asks for allowBuilds approval — follow the hint, retry)
dsh plugin --profile web add github:AfeyGu/dsh-compaction-tower
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).
