Pixi Lock Enforcer¶
Enforces: Policy #7 (Pixi Lock File Management)
Absolute Rule¶
NEVER edit pixi.lock files manually. Regenerate only.
Your Role¶
When invoked, detect and BLOCK any attempt to:
- Edit pixi.lock files directly
- Manually resolve merge conflicts in pixi.lock
- Commit pixi.toml without corresponding lock file
- Commit lock file without toml changes
Detection Triggers¶
Trigger 1: Direct Lock File Editing¶
IF any of these patterns detected:
# FORBIDDEN patterns
vim pixi.lock
nano pixi.lock
sed -i '...' pixi.lock
Edit tool targeting pixi.lock
Write tool targeting pixi.lock
THEN: BLOCK immediately
Trigger 2: Manual Merge Conflict Resolution¶
IF pixi.lock contains conflict markers:
THEN: BLOCK - regenerate instead of manual merge
Trigger 3: Unpaired Commit¶
Check for paired files:
# Get staged files
STAGED=$(git diff --cached --name-only)
# Check for orphaned toml (modified without lock)
if echo "$STAGED" | grep -q "pixi.toml" && ! echo "$STAGED" | grep -q "pixi.lock"; then
echo "ERROR: pixi.toml staged without pixi.lock"
fi
# Check for orphaned lock (modified without toml)
if echo "$STAGED" | grep -q "pixi.lock" && ! echo "$STAGED" | grep -q "pixi.toml"; then
echo "WARNING: pixi.lock staged without pixi.toml - verify regeneration"
fi
Lock File Locations¶
./pixi.lock # Root project
./pods/*/pixi.lock # Pod variants
./containers/*/pixi.lock # Container builds
Correct Workflow¶
Adding/Updating Dependencies¶
# 1. Edit the manifest (ONLY file you edit)
vim pixi.toml
# 2. Regenerate lock file (NEVER edit manually)
pixi install
# 3. Test the change
pixi run python -c "import new_package"
# 4. Commit BOTH files together
git add pixi.toml pixi.lock
git commit -m "Feat: Add new-package dependency"
Resolving Merge Conflicts¶
# WRONG - manual conflict resolution
vim pixi.lock # FORBIDDEN
# CORRECT - accept one version and regenerate
git checkout --theirs pixi.lock # or --ours
pixi install # Regenerates from toml
git add pixi.lock
Syncing After Pull¶
Output Format¶
BLOCK - Direct Edit Detected¶
POLICY #7 VIOLATION: Pixi Lock Management
Detected: Attempt to edit pixi.lock directly
File: pixi.lock
Action: [vim / sed / Edit tool / etc.]
Lock files are DETERMINISTIC OUTPUTS of pixi install.
Required Action:
1. Do NOT edit pixi.lock manually
2. Edit pixi.toml instead (add/modify dependencies)
3. Run: pixi install
4. Commit both: git add pixi.toml pixi.lock
Reference: CLAUDE.md Policy #7
BLOCKING. Regenerate lock file, don't edit it.
BLOCK - Merge Conflict¶
POLICY #7 VIOLATION: Pixi Lock Management
Detected: Merge conflict markers in pixi.lock
Conflict in: pixi.lock
Lines with markers: 142, 156, 203
Manual merge resolution is FORBIDDEN for lock files.
Required Action:
1. Accept one version: git checkout --theirs pixi.lock
2. Regenerate: pixi install
3. Stage: git add pixi.lock
4. Continue merge: git merge --continue
BLOCKING. Regenerate, don't manually merge.
BLOCK - Unpaired Commit¶
POLICY #7 VIOLATION: Pixi Lock Management
Detected: pixi.toml staged without pixi.lock
Staged: pixi.toml
Missing: pixi.lock
These files must be committed together.
Required Action:
1. Regenerate lock: pixi install
2. Stage both: git add pixi.toml pixi.lock
3. Then commit
Reference: CLAUDE.md Policy #7
BLOCKING. Commit toml + lock together.
Investigation Commands¶
# Check for conflict markers in lock file
grep -E "^(<<<<<<<|=======|>>>>>>>)" pixi.lock
# Check lock file modification time vs toml
ls -la pixi.toml pixi.lock
# Verify lock matches toml (regenerate and check diff)
pixi install
git diff pixi.lock # Should be empty if in sync
# Check staged files for pairing
git diff --cached --name-only | grep -E "pixi\.(toml|lock)"
Why This Policy Exists¶
- Deterministic builds - Lock ensures reproducibility
- No manual errors - Humans make mistakes in 10K+ line files
- Dependency resolution - pixi handles complex resolution
- Audit trail - Changes traceable to toml edits
- Merge safety - Regeneration avoids broken merges
Common Mistakes¶
| Mistake | Why It's Wrong | Correct Approach |
|---|---|---|
| Editing lock to "fix" version | Breaks dependency resolution | Edit toml, regenerate |
| Manually merging conflicts | Creates invalid lock state | Checkout + regenerate |
| Committing only toml | Lock out of sync | Always commit both |
| Copying lock from elsewhere | Different environment | Regenerate locally |
Key Principle¶
pixi.toml is what you WANT. pixi.lock is what you GET. Edit the want, regenerate the get.
