# Fix LLM Artifacts

Apply fixes from a previous `review-llm-artifacts` run with automatic safe/risky classification.

## Usage

```
/beagle:fix-llm-artifacts [--dry-run] [--all] [--category <name>]
```

**Flags:**
- `--dry-run` - Show what would be fixed without changing files
- `--all` - Fix entire codebase (runs review with --all first)
- `--category <name>` - Only fix specific category: `tests|dead-code|abstraction|style`

## Instructions

### 1. Parse Arguments

Extract flags from `$ARGUMENTS`:
- `--dry-run` - Preview mode only
- `--all` - Full codebase scan
- `--category <name>` - Filter to specific category

### 2. Pre-flight Safety Checks

```bash
# Check for uncommitted changes
git status --porcelain
```

If working directory is dirty, warn:
```
Warning: You have uncommitted changes. Creating a git stash before proceeding.
Run `git stash pop` to restore if needed.
```

Create stash if dirty:
```bash
git stash push -m "beagle: pre-fix-llm-artifacts backup"
```

### 3. Load Review Results

Check for existing review file:
```bash
cat .beagle/llm-artifacts-review.json 2>/dev/null
```

**If file missing:**
- If `--all` flag: Run `review-llm-artifacts --all --json` first
- Otherwise: Fail with: "No review results found. Run `/beagle:review-llm-artifacts` first."

**If file exists, validate freshness:**
```bash
# Get stored git HEAD from JSON
stored_head=$(jq -r '.git_head' .beagle/llm-artifacts-review.json)
current_head=$(git rev-parse HEAD)

if [ "$stored_head" != "$current_head" ]; then
  echo "Warning: Review was run at commit $stored_head, but HEAD is now $current_head"
fi
```

If stale, prompt: "Review results are stale. Re-run review? (y/n)"

### 4. Partition Findings by Safety

Parse findings from JSON and classify by `fix_safety` field:

**Safe Fixes** (auto-apply):
- `unused_import` - Unused imports
- `todo_comment` - Stale TODO/FIXME comments
- `dead_code_obvious` - Obviously unreachable code
- `verbose_comment` - Overly verbose LLM-style comments
- `redundant_type` - Redundant type annotations

**Risky Fixes** (require confirmation):
- `test_refactor` - Test structure changes
- `abstraction_change` - Class/function extraction
- `code_removal` - Removing functional code
- `mock_boundary` - Test mock scope changes
- `logic_change` - Any behavioral modifications

### 5. Apply Safe Fixes

If `--dry-run`:
```markdown
## Safe Fixes (would apply automatically)

| File | Line | Type | Description |
|------|------|------|-------------|
| src/api.py | 15 | unused_import | Remove `from typing import List` |
| src/models.py | 42 | verbose_comment | Remove 23-line docstring |
...
```

Otherwise, spawn parallel agents per category with `Task` tool:

```
Task: Apply safe fixes for category "{category}"
Files: [list of files with findings in this category]
Instructions: Apply each fix, preserving surrounding code. Report success/failure per fix.
```

Categories to parallelize:
- `style` - Comments, formatting
- `dead-code` - Imports, unreachable code
- `tests` - Test-related safe fixes
- `abstraction` - Safe refactors

### 6. Handle Risky Fixes

For each risky fix, prompt interactively:

```
[src/services/auth.py:156] Remove seemingly unused authenticate_legacy() method?
This method has no callers in the codebase but may be used externally.
(y)es / (n)o / (s)kip all risky:
```

Track user choices:
- `y` - Apply this fix
- `n` - Skip this fix
- `s` - Skip all remaining risky fixes

### 7. Post-Fix Verification

Detect project type and run appropriate linters:

**Python:**
```bash
# Check if ruff config exists
if [ -f "pyproject.toml" ] || [ -f "ruff.toml" ]; then
    ruff check --fix .
    ruff format .
fi

# Check if mypy config exists
if [ -f "pyproject.toml" ] || [ -f "mypy.ini" ]; then
    mypy .
fi
```

**TypeScript/JavaScript:**
```bash
# Check for eslint
if [ -f "eslint.config.js" ] || [ -f ".eslintrc.json" ]; then
    npx eslint --fix .
fi

# Check for TypeScript
if [ -f "tsconfig.json" ]; then
    npx tsc --noEmit
fi
```

**Go:**
```bash
if [ -f "go.mod" ]; then
    go vet ./...
    go build ./...
fi
```

### 8. Run Tests

```bash
# Python
if [ -f "pyproject.toml" ] || [ -f "pytest.ini" ]; then
    pytest
fi

# JavaScript/TypeScript
if [ -f "package.json" ]; then
    npm test 2>/dev/null || yarn test 2>/dev/null || true
fi

# Go
if [ -f "go.mod" ]; then
    go test ./...
fi
```

### 9. Report Results

```markdown
## Fix Summary

### Applied Fixes
- [x] src/api.py:15 - Removed unused import `List`
- [x] src/models.py:42-64 - Removed verbose docstring
- [x] src/auth.py:156-189 - Removed dead method (user confirmed)

### Skipped Fixes
- [ ] src/services/cache.py:23 - User declined risky fix
- [ ] tests/test_api.py:45 - Test refactor skipped

### Verification Results
- Linter: PASSED
- Type check: PASSED
- Tests: PASSED (42 passed, 0 failed)

### Diff Summary
```bash
git diff --stat
```

## Cleanup

On successful completion (all verifications pass):
```bash
rm .beagle/llm-artifacts-review.json
```

If any verification fails, keep the file and report:
```
Review file preserved at .beagle/llm-artifacts-review.json
Fix issues and re-run, or restore with: git stash pop
```

## Example

```bash
# Preview all fixes without applying
/beagle:fix-llm-artifacts --dry-run

# Fix only dead code issues
/beagle:fix-llm-artifacts --category dead-code

# Full codebase scan and fix
/beagle:fix-llm-artifacts --all

# Fix style issues only, preview first
/beagle:fix-llm-artifacts --category style --dry-run
```
