dsh-janitor

Deterministic artifact lifecycle for DeepSeek Harness (dsh).

Agent sessions leave debris: plan docs from finished tasks, scratch scripts, one-off fixtures. People fear agent-driven cleanup precisely because cleanup driven by an agent is unaccountable. This plugin registers a janitor_scan tool that runs the agent-janitor engine over the workspace and returns a reviewable cleanup plan — every candidate file with a deterministic verdict (protected / keep / recent / needs-review / safe-to-remove) and the evidence behind it.

The janitor is never an agent. The scan and verdicts are pure deterministic rules (reference analysis, git metadata, age thresholds); v0.1 never deletes anything — applying a reviewed plan stays with the upstream CLI or with you, on purpose.

Family: read-guard (what agents read) · pr-gate (what they write) · attest (what they did) · mcp-test (what they can call) · janitor (what they leave behind).

Why now (checked 2026-10-12)

Nothing in the dsh ecosystem does deterministic workspace hygiene. The @goodandready/dsh-time-machine plugin does checkpoints and rollback (snapshot safety), which is complementary: it answers "can I undo?", this answers "what is safe to remove?". Deterministic scan → reviewable plan → apply as a three-step, non-agent pipeline is unowned.

Verdicts (fixed order, first match wins)

verdict	meaning
protected	exact file or directory prefix in the protected list
keep	referenced by any code file
recent	younger than minAgeDays (git commit time preferred)
needs-review	referenced by docs/other, or otherwise ambiguous
safe-to-remove	plan doc with task merged & zero refs, or zero refs + old enough

Install

dsh plugin --profile default add dsh-janitor

From npm — no build step, no allowBuilds authorization; git installs are equally prebuilt (lib/ ships in the repo).

Configure

- id: dsh-janitor
  name: dsh-janitor
  config:
    minAgeDays: 14
    protectedPaths: ["plans", "docs/decisions"]   # exact file or directory prefix

Develop

npm install
npm test   # syncs the vendored agent-janitor engine, builds, runs fixture tests

The scan/verdict engine is vendored from the sibling agent-janitor checkout (npm run sync; CI runs sync --check).

Roadmap

• janitor_apply with an explicit per-path confirmation protocol (still deterministic — no agent judgment in the loop)
• Session-debris presets (.dsh-* ledgers, scratch plugins dirs)
• Plan archive integration with the upstream CLI's apply

Kill criteria

If dsh ships first-party workspace hygiene, or time-machine-style plugins add deterministic removal planning, this freezes at its last working version with a postmortem here. The engine stays owned by agent-janitor either way.
