Step 9 of v3.4.1 plan.
lib/util/cleanup.mjs (new):
- cleanupProject(projectDir, {dryRun, confirm}) reads
.session-state.local.json via validateSessionState; refuses unless the
parsed status is strictly equal to 'completed' (per risk-assessor
Critical 2 — no soft-match on similar statuses).
- Default dryRun: true; refuses dryRun: false without explicit
confirm: true (CLEANUP_REQUIRES_CONFIRM).
- Removes .session-state.local.json + NEXT-SESSION-PROMPT.local.md
candidates; ENOENT counts as "already absent" so the function is
idempotent.
- No CLI shim — invoked from /ultracontinue --cleanup via inline ESM
(Step 10 wires this in).
tests/lib/cleanup.test.mjs (new):
- 7 cases: dry-run lists candidates without deleting; confirm-mode
deletes both files; idempotent re-run signals CLEANUP_NO_STATE_FILE
after fully cleaned; refuses on status: in_progress
(CLEANUP_NOT_COMPLETED); refuses dryRun: false without confirm
(CLEANUP_REQUIRES_CONFIRM); defaults to dry-run; missing state file
returns CLEANUP_NO_STATE_FILE.
Internal scaffolding consumed by Step 10 (Phase 0.5 wire-up). User-facing
docs land with Step 14.
Tests 348 -> 355 (+7).

Three changes in one commit:
1. NEW lib/util/atomic-write.mjs — exports atomicWriteJson(path, obj),
the canonical tmp+rename pattern. Reused by pre-compact-flush.mjs and
(in subsequent steps) by the new session-state writer.
2. NEW tests/lib/atomic-write.test.mjs — 4 unit tests covering
round-trip, no-orphan-tmp, overwrite-atomic, pretty-print formatting.
3. REFACTOR hooks/scripts/pre-compact-flush.mjs — replace the inline
atomicWrite() with the imported atomicWriteJson(). Also fixes a
pre-existing syntax error (leading whitespace + stray --resume token
outside the comment block) that silently broke the hook from v3.1.0
onward — PreCompact runtime is fail-open and swallowed the error.
File reformatted with standard zero-indent JS.
163 → 167 tests, 0 fail.
Step 2 of /ultracontinue v3.3.0 (project 2026-05-01-ultracontinue).
Step 1 of v2.0 plan. Hard cut from commands/ to skills/ per Anthropic
recommendation for new plugins. Frontmatter sets disable-model-invocation:
true and pins model: claude-sonnet-4-6. Docs (README, CLAUDE.md, root
README) deferred to Step 9 per plan.
