+# `/kaizen` Command Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Build the `/kaizen` kaizen-loop command — a stdlib scanner that parses `docs/FRICTION.md` *Open signals* plus an interactive command that curates them (add/change/park/remove) into the decisions ledger.
+
+**Architecture:** Mirrors `/review-repo` exactly: a deterministic stdlib Phase-0 scanner (`scripts/friction-scan.py`, unit-tested) feeds a markdown command (`.claude/commands/kaizen.md`) that drives the interactive curation. The same scanner powers a stage-2 nudge surfaced in `/review-repo`.
+
+**Tech Stack:** Python 3 standard library only (matches `scripts/repo-scan.py`); pytest; markdown command docs.
+
+**Spec:** `docs/superpowers/specs/2026-06-14-kaizen-command-design.md`
+
+---
+
+## File structure
+
+- Create: `scripts/friction-scan.py` — stdlib parser of `FRICTION.md` *Open signals*; `--json` (default) and `--nudge` modes. One responsibility: turn the prose signal log into structured data + the nudge line.
+- Create: `tests/test_friction_scan.py` — unit tests for the parser (string-based, deterministic via `--today`), matching `tests/test_repo_scan.py`.
+- Create: `.claude/commands/kaizen.md` — the interactive curation process.
+- Modify: `.claude/commands/review-repo.md` — add the stage-2 nudge line to its report.
+- Modify: `STATUS.md` — add a `/kaizen` row.
+- Modify: `docs/TODO.md` — mark item 11.1 in progress / built.
+
+All scanner logic lives in functions that take strings/data (not files) so tests need no fixtures on disk; only `load_signals(path, today)` and `main()` touch the filesystem.

+
+Write `.claude/commands/kaizen.md` with exactly this content:
+
+````markdown
+# Kaizen — curate the friction log into improvements
+
+Consume the **Open signals** in `docs/FRICTION.md`: decide a verdict for each, migrate
+durable knowledge into the right docs, and archive consumed signals into the decisions
+ledger. **Curate-only** — do not hunt for new signals; capture stays manual. This is an
+interactive, judgment-dense pass: propose, the operator decides, you apply on approval.
+
+Design: `docs/superpowers/specs/2026-06-14-kaizen-command-design.md`.
+
+## Phase 0 — scan
+Run `python3 scripts/friction-scan.py > /tmp/kaizen.json`. It returns each Open signal as
+`{tag, first_seen, age_days, recurrence_count, referenced_paths, still_exists, text}`.
+Treat `still_exists: false` as a hint the signal may already be resolved.
+
+## Phase 1 — triage
+Order signals by `recurrence_count` desc, then `age_days` desc, then tag. **Group signals
+that share a root cause** and curate them together. Present the agenda before editing
+anything: total open, how many recurring (≥3), how many look already-resolved.
+
+## Phase 2 — per-signal curation (interactive)
+For each signal/group, present: a one-line restatement, the evidence (age, recurrence,
+still-real), and a proposed **verdict**. Verdicts:
+
+- **SYSTEMATIZE** — migrate the durable lesson into its right home (a runbook, an ADR,
+  `CLAUDE.md`, a new `scripts/repo-scan.py` check, or a hook).
+- **CHANGE** — adjust an existing tool/convention/config rather than document it.
+- **PARK** — *out-of-phase but not obsolete*. Remove from the active tree, but write a
+  ledger row recording **where it now lives (git SHA/branch/doc) and a resurrection
+  trigger**. The default for "not touched lately but not wrong."
+- **REMOVE** — *obsolete*: superseded, wrong, never worked, duplicated. Ledger row states
+  why.
+- **ALREADY-BUILT** — the systematization already exists / the fix landed; archive.
+- **ACCEPTED** — conscious no-op (revisit-if-recurs); archive.
+- **KEEP-OPEN** — still accruing, not ripe; leave it in *Open signals* (no ledger row).
+
+Rules:
+- **Knowledge is never removed** — SYSTEMATIZE/migrate it; only *active surface* (scripts,
+  checks, conventions, plugins) is parked/removed.
+- Every reductive verdict must classify *why unused*: **obsolete → REMOVE**,
+  **out-of-phase → PARK**.
+- The operator approves / modifies / rejects each verdict. On approval: do the mechanical
+  edit (migrate text into the target doc; **move the signal from *Open signals* into the
+  ledger table**; delete the parked/removed file) and show the diff.
+- PARK and REMOVE both delete from the active tree — the difference is the ledger row.
+  Git history + the ledger row are the park mechanism; never create a `parked/` directory.
+
+## Phase 3 — close-out
+- Add a new dated block under `## Kaizen reviews — decisions ledger` (newest first), same
+  shape as the existing block: a table with columns **Signal (first seen) | Verdict |
+  Resolution / where it lives now**.
+- **Bias-to-remove discipline check:** if every verdict this pass was SYSTEMATIZE/CHANGE
+  (only accreting), say so explicitly.
+- **Self-eval (light):** is `/kaizen` being run often enough (oldest consumed age)? Should
+  the nudge thresholds in `scripts/friction-scan.py` change? Note it.
+- Run `make lint` if any code/docs changed; revert anything that breaks it.
+- Commit per `CLAUDE.md` git conventions (one logical unit — straight to `main` if
+  small/safe, a branch if sweeping; show the diff first for a branch).
+- Print a one-line summary: `consumed X · parked Y · removed Z · kept-open W · migrated → <docs>`.
+
+## Headless / cron (future)
+Deferred until the notify + cron stack exists (`docs/TODO.md` 11.3). When run
+non-interactively, **report only**: print the proposed verdicts and the nudge, do not edit
+or commit.
+````
+
+- [ ] **Step 2: Verify it parses against the real log**
+
+Run: `python3 scripts/friction-scan.py --today 2026-06-15 | python3 -c "import sys,json; print(len(json.load(sys.stdin)), 'signals')"`
+Expected: prints a non-zero signal count with no traceback.
+
+- [ ] **Step 3: Lint**
+
+Run: `make lint`
+Expected: passes (markdown isn't linted by yamllint/ansible-lint, but this confirms nothing else broke).
+
+- [ ] **Step 4: Commit**
+
+```bash
+git add .claude/commands/kaizen.md
+git commit -m "feat(kaizen): /kaizen command — interactive friction curation"

+
+## Task 6: Stage-2 nudge in `/review-repo` + STATUS/TODO
+
+**Files:**
+- Modify: `.claude/commands/review-repo.md`
+- Modify: `STATUS.md`
+- Modify: `docs/TODO.md`
+
+- [ ] **Step 1: Add the nudge to the review-repo command**
+
+In `.claude/commands/review-repo.md`, find the "Phase 0 — deterministic pre-scan" section
+(it runs `scripts/repo-scan.py`). Immediately after that paragraph, add:
+
+```markdown
+Also run `python3 scripts/friction-scan.py --nudge` and include its one-line output in the
+report's summary — it flags when the kaizen loop (`/kaizen`) is overdue (recurring signals,
+backlog size, or age). This is a reminder only; do not act on `FRICTION.md` from here.
+```
+
+- [ ] **Step 2: Add a STATUS row**
+
+In `STATUS.md`, under "Real and working today", add a row:
+
+```markdown
+| `/kaizen` | Curate `docs/FRICTION.md` Open signals → decisions ledger (`scripts/friction-scan.py` Phase 0 + `.claude/commands/kaizen.md`). On-demand; `--nudge` surfaces in `/review-repo`. Headless/cron deferred (TODO 11.3). |
+```
+
+- [ ] **Step 3: Update TODO 11**
+
+In `docs/TODO.md` item 11, mark sub-item 1 built:
+
+Change `1. Build `/retro`: ...` to begin with `1. ~~Build `/retro``... ` — i.e. strike it
+through and append: `DONE — built as `/kaizen` (scope narrowed to curate-only per the
+2026-06-14 spec; `/retro` name dropped). `scripts/friction-scan.py` + `.claude/commands/kaizen.md`.`
+
+- [ ] **Step 4: Lint**
+
+Run: `make lint`
+Expected: passes.
+
+- [ ] **Step 5: Commit**
+
+```bash
+git add .claude/commands/review-repo.md STATUS.md docs/TODO.md
+git commit -m "feat(kaizen): nudge in /review-repo; STATUS + TODO"
+```

+
+## Task 7: Dogfood — first real `/kaizen` run
+
+This task is **not** automated; it is the first real use, done interactively with the operator.
+
+- [ ] **Step 1:** Run `/kaizen` against the current Open signals (there are several,
+  including the 3 added 2026-06-14 and the 5× execution-mode-menu signal).
+- [ ] **Step 2:** Work the interactive curation (Phase 2) with the operator, applying
+  verdicts on approval.
+- [ ] **Step 3:** Confirm the close-out: ledger updated, `make lint` green, summary printed.
+  This both processes the backlog and validates the command end-to-end.
+
+---
+
+## Self-review notes (author)
+
+- **Spec coverage:** scope-A curate-only → Task 5 Phase 0–2; verdict model incl. PARK →
+  Task 5 Phase 2 + ledger; single source FRICTION.md → Task 4 `load_signals`; interactive
+  apply (B) → Task 5; ledger format → Task 5 Phase 3; scanner schema → Tasks 2–4; nudge +
+  thresholds → Task 4 + Task 6; out-of-scope items → not built (correct); `/review-repo`
+  relationship → Task 6 nudge. All covered.
+- **No placeholders:** every code step shows complete code; the command doc is written in
+  full.
+- **Type consistency:** the signal dict keys (`tag, first_seen, age_days,
+  recurrence_count, referenced_paths, still_exists, text`) are identical across Tasks 2–4
+  and the command doc; `nudge_line` reads `age_days`/`recurrence_count` only.
