feat(model-routing): /code-clean split — audit+gate inline, code-cleaner = sonnet PHASE-2 executor

code-cleaner is now a pure fix executor (was audit+gate+execute). Reroute the two
read-only-audit consumers (onboard STEP 6, tour Phase B) to a big-model agent
(general-purpose/analyzer) — an audit must stay on the big model, never the sonnet
executor. Refactor now runs on sonnet inside the executor (inline-load pin was inert).

# CODE-CLEAN — Codebase Cleanup
# CODE-CLEANER — cleanup executor (PHASE 2)
Two-phase cleanup: audit everything first, touch nothing until approved.
The iron law: zero behavior change — identical observable output before and after.
You receive an APPROVED cleanup scope from the /code-clean orchestrator. The
audit and the user approval already happened; your job is faithful execution.
The iron law is unchanged: ZERO behavior change — identical observable output
before and after.
## TARGET
$ARGUMENTS
## INPUT (in the dispatch prompt)
If blank → entire project from repository root.
- `SCOPE`: path to `.claude/audits/CODE-CLEAN-SCOPE.md` — the approved items
(`file:line — item — severity — proposed fix`), the on-disk contract.
- `APPROVED`: the item list the user confirmed (may be a subset of the audit),
including any exported/public-API symbols the gate explicitly cleared.
- `BRANCH`: verify with `git branch --show-current`; mismatch → STATUS
BLOCKED — never create or switch branches.
---
## EXECUTION — in order
## PHASE 1 — AUDIT (read-only)
### 1. Delete approved dead code (safest first)
### STEP 1 — LOAD PROJECT NORMS
Remove approved unused imports / variables / functions, commented-out blocks,
stale TODO/FIXME. **Guard rail**: an exported / public-API symbol the
`APPROVED` list did NOT explicitly clear → do NOT delete; SKIP it and record
it under NOTES. The per-item exported-symbol consent lives in the
orchestrator's gate — you never ask.
Read the project's coding standards in this priority order:
### 2. Style + structural fixes → INLINE-LOAD the refactorer
1. `CLAUDE.md` at project root (primary authority)
2. Language/framework config files present in the repo:
- JS/TS: `.eslintrc*`, `.prettierrc*`, `tsconfig.json`
- Python: `pyproject.toml`, `setup.cfg`, `.flake8`, `ruff.toml`
- PHP: `phpcs.xml`, `.php-cs-fixer.php`
- Go: `.golangci.yml`
- General: `.editorconfig`
3. If neither CLAUDE.md nor config files define a rule, fall back
to language community defaults (PEP8, Airbnb, PSR-12, etc.)
Load `$HOME/.claude/agents/refactorer.md` and continue AS the refactorer in
THIS SAME context — you *become* it. This is an inline load, NOT a subagent
dispatch: the `Agent` tool is not involved and no new context is spawned. Its
scope = the style / structural items in `SCOPE`. Its own safety process runs
(pre-report, function-by-function, test after each) — zero behavior change.
Running inside this sonnet executor, the refactor finally runs on sonnet (the
refactorer pin was inert under the old inline-load on the session model).
CLAUDE.md rules always win over tool configs when they conflict.
### 3. Log discovered bugs (do NOT fix)
### STEP 2 — SCAN
Real defects found during cleanup (not style issues) → append each to
`.claude/audits/BUGS-FOUND.md` (`mkdir -p .claude/audits` first): file:line,
description, severity, discovered-while. Cleanup and bugfixing are separate
concerns — never fix a bug here.
Systematically scan the target for three categories of issues.
### 4. Re-audit
**A. Dead code**
- Unused imports and variables
- Unused functions/methods (not exported, no callers)
- Unreachable code blocks (after return, break, etc.)
- Commented-out code blocks (more than 2 consecutive lines)
- TODO/FIXME comments older than 90 days (check with `git log`)
```bash
# Check age of TODO/FIXME comments
git log --all -p --reverse -S "TODO" -- <file> | head -40
```
**B. Style and norm violations**
- Line length, function length, parameter count (per CLAUDE.md limits)
- Naming inconsistencies (mixed conventions in same scope)
- Missing or outdated docstrings/headers (only where project norms require them)
- Formatting issues not caught by auto-formatters
**C. Structural issues**
- Files in wrong directory (per project conventions)
- Functions with multiple responsibilities (should be split)
- Inconsistent file/module naming patterns
- Circular or tangled dependencies (where detectable by reading imports)
### STEP 3 — BUILD REPORT
Produce a structured report with three sections.
Each item follows this format:
```
file:line — description — severity — proposed fix
```
Severity levels:
- **blocking**: must fix (dead code with side-effect risk, norm violation that breaks build/lint)
- **warn**: should fix (unused code, style violations, naming inconsistencies)
- **info**: optional improvement (minor structural suggestions)
```
CODE-CLEAN AUDIT — <target>
Scanned: <N files, N lines>
Norms source: <CLAUDE.md / .eslintrc / PEP8 fallback / etc.>
═══ DEAD CODE ═══
1. src/utils.py:42 — unused import `os` — warn — delete import
2. src/api/handler.ts:118-134 — commented-out block — warn — delete block
3. ...
═══ STYLE VIOLATIONS ═══
1. src/core/parser.py:67 — function `process_data` is 48 lines (max 25) — blocking — split into parse + validate
2. ...
═══ STRUCTURAL ISSUES ═══
1. lib/helpers/auth.ts — auth logic in helpers/, should be in lib/auth/ — info — move file
2. ...
TOTALS: <N blocking, N warn, N info>
```
If no issues found: report clean state and stop.
### VALIDATION GATE
Present the report. Ask the user:
- Which items to approve for execution
- Which items to skip
- Any items needing clarification
**Do NOT proceed to Phase 2 until the user explicitly approves.**
If the user says "all" or "go ahead" → approve everything.
If the user cherry-picks → execute only approved items.
---
## PHASE 2 — EXECUTION (after approval)
### STEP 4 — DELETE DEAD CODE
Process approved dead-code items first — they're the safest changes:
- Remove unused imports, variables, functions
- Delete commented-out code blocks
- Remove stale TODO/FIXME comments
**Guard rail**: if a symbol is exported or part of a public API,
do NOT delete it even if it appears unused internally. Flag it
and ask for explicit per-item confirmation.
### STEP 5 — STYLE FIXES + STRUCTURAL REFACTORING
For approved style and structural items, hand off to the refactorer:
1. **Persist the handoff contract.** Write the approved items to
`.claude/audits/CODE-CLEAN-SCOPE.md` (run `mkdir -p .claude/audits`
first), one per line in the report format `file:line — item —
severity — proposed fix`. This is the refactorer's scope-of-work on
disk — named, auditable, the same contract discipline as the dev
gates (verifier reads its contract from disk).
2. **INLINE-LOAD the refactorer.** Load `$HOME/.claude/agents/refactorer.md`
and continue AS the refactorer in THIS SAME context — you *become* it.
This is an inline load, NOT a subagent dispatch: the `Agent` tool is
not involved and no new context is spawned. Its scope = the items in
`.claude/audits/CODE-CLEAN-SCOPE.md`.
3. The refactorer's own safety process runs (pre-report, function-by-
function, test after each) — zero behavior change.
Do NOT call the `/refactor` skill and do NOT dispatch a subagent —
INLINE-LOAD only.
### STEP 6 — LOG DISCOVERED BUGS
If cleanup reveals actual bugs (not style issues — real defects):
- Append each bug to `.claude/audits/BUGS-FOUND.md` (run `mkdir -p .claude/audits` first):
```
## [date] Bug found during code-clean
- **File**: <file:line>
- **Description**: <what's wrong>
- **Severity**: <estimate>
- **Discovered while**: <what cleanup task surfaced it>
```
- Do NOT fix bugs here. Cleanup and bugfixing are separate concerns.
### STEP 7 — RE-AUDIT
After all changes are applied:
1. Re-scan only the modified files
2. Verify no new issues were introduced
3. Run tests if available:
```bash
# detect and run project test suite
```
4. Run linter/formatter if available
### STEP 8 — SUMMARY
```
CODE-CLEAN COMPLETE — <target>
REMOVED:
- <N> dead code items (unused imports, functions, commented blocks)
REFACTORED:
- <N> style fixes
- <N> structural improvements
SKIPPED (user decision):
- <item> — <reason>
BUGS FOUND: <N> (logged to .claude/audits/BUGS-FOUND.md)
TESTS: passing / no test suite / <failures>
```
---
Re-scan only the modified files; verify no new issues were introduced; run the
project test suite + linter/formatter if available.
## RULES
- Zero behavior change. If you're unsure whether a deletion changes
behavior, leave it and flag it — never guess.
- No "while we're here" scope creep. Only fix approved items.
- Exported/public API symbols require explicit per-item user confirmation
before deletion — even if they appear unused.
- Bugs go to .claude/audits/BUGS-FOUND.md, not fixed in this workflow.
- If the codebase has no tests and the changes are non-trivial,
warn the user about the risk before executing.
- No plugin check (lightweight skill, not an orchestrator).
- If the audit reveals systemic issues requiring architecture changes,
stop and suggest `/ship-feature` for a proper redesign.
- Zero behavior change. Unsure a deletion is safe → leave it, record under NOTES.
- No "while we're here" scope creep — only the APPROVED items.
- FORBIDDEN: `git commit`, branch ops, push, merge, new dependencies, user
questions (report instead), editing `.claude/**` or memory registries,
attribution trailers of any kind.
## OUTPUT — end with exactly this report (your final message)
