# /supergraph:fix

Plan-aware auto-fix loop. Ensure tests pass, lint clean, format applied, graph risks handled.

## Usage

`/supergraph:fix` | `/supergraph:fix plan auth-login` | `/supergraph:fix plan auth-login task 2`

## Steps

### 0. Announce
"🔧 /supergraph:fix — starting auto-fix loop..."

### 1. Select Plan Context

0 plans → skip | 1 → use | >1 → ask | `plan <slug>` → match.
Read `## Environment Context`, fix scoped task or all in-progress/stuck tasks.

### 2. Get Commands

Read from plan `## Environment Context` or `.supergraph-env` (set by `/supergraph:scan`). Missing → STOP, run scan first.
Missing command → skip phase, report as `SKIP`.

### 3. Get Changed Files
`git diff --name-only && git diff --cached --name-only`. Reindex `CBM_PROJECT` if stale (`index_status`→`index_repository`, see `references/codebase-memory-contract.md`) via `codebase-memory-mcp`.

### 3b. Serena pre-loop (optional): See `serena/SKILL.md:Setup`. If scan not run, call `initial_instructions`; `get_diagnostics_for_file` per changed file to catch type errors early. Skip if `SERENA_ACTIVE=false` or unavailable.

### 4. Auto-Fix Loop (max 3 iterations)

At iteration start: "🔧 Fix iteration N/3 — running tests..."

| Phase | Action |
|---|---|
| Reproduce | Smallest failing cmd + expected vs actual |
| Tests | Targeted tests else `$TEST_CMD`; fix source. **Dedup:** if same `HEAD_SHA` and last `PASS <120s` and `git diff` unchanged, reuse evidence; else rerun fresh (respects `verify` freshness guard) |
| Serena fix | `get_diagnostics_for_file` + `replace_symbol_body`/`rename_symbol` (see `serena/SKILL.md`) |
| Format+Lint | `$FORMAT_CMD`→`$LINT_CMD`; rerun lint if formatted |
| Graph | Reindex `CBM_PROJECT` if stale (`index_status`→`index_repository`) — respect `scan: TTL 10m` (skip `index_repository` if fresh per `.supergraph-env`), then `codebase-memory-mcp` recipes `cycles/test-gaps/complexity/cross-boundary` |
| Decide | All clean→break else continue |

### 5. Update Plan Status (if plan exists)

- Succeeded → `Status: completed`
- Failed after 3 → `stuck` + append STUCK log
- Never mark completed if tests or lint fail

### 6. Report

```
## Auto-Fix Report
- Iterations: N/3 | Tests: PASS|FAIL|SKIP | Lint: PASS|FAIL|SKIP | Format: PASS|SKIP
- Graph: PASS|WARNING|CRITICAL | Plan status: updated|none
- Issues: [list or "none"]
Next: /supergraph:verify → /supergraph:review
```

## Rules

- Max 3 fix iterations
- Never commit broken code
- Never use `git add -A`
- Never hide failures by weakening tests
- Prefer source fixes over test edits
- CRITICAL graph findings: fix or escalate
- Warnings: fix or report
- Prefer `mcp__serena__replace_symbol_body` for body fixes and `mcp__serena__rename_symbol` for renames when Serena is available
