Deep-clean a repository with the deletion test: delete a unit — a whole dead directory, a file, a region, a line, a word — and let the project's own oracle (build, typecheck, tests) rule. Nothing observable changed? The unit is provably-dead. The oracle objects, or can't see the unit at all (oracle-blind)? It stays live. Here every deletion is a probe — delete → oracle → always revert — that gathers evidence and commits nothing. You probe, you propose, the human approves; only then do approved removals apply. The append-only coverage ledger records every verdict so a massive repo is cleaned incrementally across runs.
Announce at start: "Using house-cleaning to audit <target> (propose-only)."
Scope: /house-cleaning [dir] — default repo root. Scoping slices the audit; it never silently skips.
When NOT to use: a dirty working tree, an untrusted repo (the oracle runs its code), or when you want deletions applied without review — this tool asks first, every time.
NO PROPOSAL WITHOUT A CANDIDATE RECORD
If it never entered as a candidate, it does not leave as a proposal — either as itself, or as the coarser unit it descends from. Units are nominated at Stage 1 and carried down; they are not invented at approval time. Resuming a prior run is no exception: coverage-view --since invalidates stale coverage but writes nothing — re-nominate those units yourself at Stage 1 so they carry a candidate record in this run before anything proposes them. Caught one after the fact? Drop it from the manifest, append a superseding decision:declined, record a kept, and say so in the report.
Standing prohibitions
cull.sh apply runs only the human-authorized manifest.git checkout -- <path> — then re-probe; a dirty tree invalidates every verdict that follows. Never restore the whole tree: .house-cleaning/ carries ledger records not yet checkpointed, and a repo-wide checkout discards them.house-cleaning/<date> branch; never merge red.cull.sh before Stage 0 closes. A probe against an undetected oracle or an unverified baseline proves nothing — it produces verdicts that look identical to real ones..house-cleaning/) · house-cleaning/* branch only · keep-list untouchable · secret-shaped paths refuse · untracked archived before removal.scripts/ledger.sh / scripts/cull.sh so the coverage ledger exists — never substitute a hand-rolled cp/rm/manual test-run probe for those scripts. Recorded by hand? The coverage ledger is wrong and resumption will lie — re-record through the script before the stage closes.The run id set by scripts/ledger.sh init (Stage 0) sticks via .house-cleaning/current-run —
you do NOT need to re-export HC_RUN_ID on every call. Storage is committed by default
(HC_LEDGER_MODE=committed); flip to local for a no-commit, gitignored ledger. In committed
mode, flush the ledger/audit at stage boundaries with scripts/ledger.sh checkpoint "$HC_RUN_ID".
If you catch yourself thinking…
| Thought | Reality |
|---|---|
| "It's not dead, but it's an easy win" | Out of scope. This skill removes dead code and stale prose. Not untidy code. |
| "I'll flag it as optional, so it's honest" | Disclosing scope creep doesn't bring it in scope. Don't surface it. |
| "I declined it, so it's handled" | A decline without a kept record still reads as proposed. |
| "It's obviously dead — the probe is a formality" | Obvious isn't evidence. If the oracle can evaluate it, probe it. If it can't, record oracle-blind and say why. |
| "I'll write up the evidence after approval" | The human approves on evidence. No evidence, nothing to approve. |
| "The baseline is probably green" | Probably ≠ green. Run it. A red baseline invalidates every verdict after it. |
| "I'm not sure, so I'll leave it out" | Silence isn't restraint — it's an uncovered unit. If the oracle can't see it, that's oracle-blind (which becomes a proposal). If you can't establish it's dead, don't nominate it — record kept at Stage 1, with the reason. Recording it is not the same as surfacing it. |
Violating the letter of these lines is violating the spirit of them.
Copy-paste setup, one shot — the run id sticks (see above), so nothing further to export:
git checkout -b house-cleaning/<yyyy-mm-dd>
scripts/ledger.sh init <yyyy-mm-dd-hhmm> <scope> "$(git rev-parse HEAD)"
.house-cleaning/) or a non-git repo. Branch: as above — never main.scripts/oracle.sh detect prints proposed commands; show them and get the user's confirmation before writing .house-cleaning/oracle. Trust boundary — the oracle executes this repo's code.scripts/oracle.sh run twice. Red ⇒ stop and report. A flake ⇒ record it and demote confidence..house-cleaning/keep; offer to seed it (entry points, migrations, licenses).oracle and baseline records.Done when: the ledger holds run + oracle + baseline records, the keep-list is read, and the house-cleaning/<date> branch exists.
Nominate candidates from static detectors (references/tools.md); dynamic languages need two independent signals. Nominate the coarsest unit the evidence supports — a whole dead directory or module is one candidate, not a hundred. Enumerate untracked files (git ls-files --others --exclude-standard) and classify them; untracked removals are always proposals (git can't undo them). Record each in-scope unit as a candidate (evidence + tier + granularity) or a kept record via scripts/ledger.sh append "$HC_RUN_ID" candidate '{…}'.
Done when: every in-scope unit is a candidate or kept ledger record, and scripts/ledger.sh regen-audit "$HC_RUN_ID" is refreshed.
Run the deletion test, batch-first: scripts/cull.sh probe batch <listfile> deletes the whole batch, runs the oracle once, and reverts. Collective green ⇒ every member is provably-dead; red ⇒ the script isolates the live members and the survivors descend coarse-to-fine to scripts/cull.sh probe region|bisect <path> <start> <end>. Every probe logs a verdict and records coverage; nothing is committed or applied.
cull.sh probe only ever writes provably-dead (oracle green) or kept-live (oracle red). A candidate the deletion test cannot safely evaluate at all — dynamic access, reflection, an untested path with no oracle coverage — you record as oracle-blind yourself (scripts/ledger.sh append "$HC_RUN_ID" probe '{…}'); an oracle-blind unit always becomes a proposal, never auto-anything.
Done when: every candidate carries a probe verdict — provably-dead, oracle-blind, or kept-live — in the ledger.
On the survivors only, go to word granularity. Code tokens: oracle-gated probe region|bisect, deletion only (never renaming); an oracle-surviving deletion that hurts a human reader demotes to a proposal. Prose (comments, docstrings, docs): meaning-based per references/prose.md — always proposals, no machine oracle. This is budget-bounded: exhaustive per unit examined, but coverage is incremental — on hitting the per-run budget, checkpoint and report the remainder, never truncate silently. End every run with the mandatory, forced-visible coverage summary — scripts/ledger.sh coverage-summary "$HC_RUN_ID" prints a coverage: line ("swept X of Y candidates; N uncovered"). Never claim "done" while coverage is partial.
Done when: in-scope survivors are audited to word level or a partial checkpoint is recorded, and the coverage: summary is shown.
Regenerate the audit — scripts/ledger.sh regen-audit "$HC_RUN_ID" — and present it as forced-visible-output, grouped by confidence, evidence-forward:
Request approval through the harness's structured question tool where available, else a numbered plain-text list, then stop for the reply. The human's selection is the apply manifest. Record each choice as a decision (approved/declined) ledger record — that record is audit trail, not the enforcement.
Every declined unit also needs a kept record. The decision says how the human ruled; the kept record says the unit stays, and it is the kept record that retracts the unit from the run's proposal set. Decline without one and the unit still reads as proposed to anyone auditing the run. This covers anything you surfaced and then ruled out — including items ruled out as out of scope rather than as live code (a config entry, a stylistic edit inside a live file). Better still, keep out-of-scope items out of the decision stream entirely: it is for units you are proposing to remove.
MUST NEVER write a decision:approved record or call cull.sh apply without a human authorization in the same turn — approval is a forced human turn, not an agent-authored record.
Done when: every proposed unit has a decision record, every declined unit also has a kept record, and the approved units form the apply manifest.
Apply only the approved manifest. Two paths, by granularity:
scripts/cull.sh apply <manifest> (tracked — each deletion → oracle → atomic commit) and scripts/cull.sh apply-untracked <listfile> (untracked — archive-first). Both do a whole-path removal only; a region/word unit like foo.ts:2-2 is not theirs to handle.cull.sh verbs. Re-probe at current positions first (never replay stale line numbers), edit out the approved region/tokens, run scripts/oracle.sh run; on green commit atomically (append an applied record — scripts/ledger.sh append "$HC_RUN_ID" applied '{…}' — then git commit), on red git checkout -- <file> to restore and mark it kept-live.Final gate: full scripts/oracle.sh run. Red ⇒ git bisect across the branch's atomic commits, revert the culprit, re-run to green — never merge red. Then regenerate the audit and persist the additive audit/ledger to the base branch: scripts/ledger.sh persist-base <base_branch> "$HC_RUN_ID" (additive-only — adds .house-cleaning/ files, touches no code) so history and resumption survive even if the deletions are abandoned. Deletions stay on the house-cleaning/<date> branch; the merge or PR is the user's call.
Done when: approved deletions are atomic oracle-green commits, the final oracle is green, and the audit/ledger is persisted to the base branch.
On every invocation, read the ledger to see what scope has been swept and resume the uncovered remainder: scripts/ledger.sh coverage-view --since invalidates coverage for files changed since their recorded sha — it reports, it does not write, so you re-nominate and re-probe those units yourself. "Know what scope you're looking at" is just the coverage summary — this is how the tool cleans a massive repo across many runs.
