performance-optimizer from smicolon/ai-kit is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add smicolon/ai-kit/performance-optimizer@git:20260903.50c14caPins git:20260903.50c14ca in mdr.lock. Pin the fingerprint instead.

This skill should be used when the user asks to "optimize queries", "fix slow queries", "improve performance", "detect N+1", "add indexes", or when writing Django ORM queries that access related objects. Detects and fixes performance issues.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Performance Optimizer
Auto-detects and fixes Django ORM performance issues before they reach production.
## Activation Triggers
This skill activates when:
- Writing ORM queries
- Accessing related objects (foreign keys, M2M)
- Creating views that fetch data
- Mentioning "slow", "performance", "optimization"
- Looping over querysets
- Creating list/detail views
## Performance Targets
- ✅ NO N+1 queries
- ✅ Appropriate indexes on frequently queried fields
- ✅ Pagination for list endpoints
- ✅ `select_related()` for foreign keys
- ✅ `prefetch_related()` for reverse foreign keys and M2M
- ✅ Caching for expensive operations
## Auto-Detection Patterns
### Pattern 1: N+1 Query Detection
**❌ INEFFICIENT (N+1 query):**
```python
# Bad: 1 query for users + N queries for organizations
users = User.objects.all() # 1 query
for user in users: # N queries
print(user.organization.name) # Hits DB each time!
```
**✅ OPTIMIZED:**
```python
# Good: 2 queries total (1 for users + 1 JOIN for organizations)
users = User.objects.select_related('organization').all()
for user in users:
print(user.organization.name) # No DB hit!
```
### Pattern 2: Reverse Foreign Key N+1

How to install
mdr add smicolon/ai-kit/performance-optimizer@sha256:cceaf0c4f89ac14bThe line at the top of this page pins the label git:20260903.50c14ca, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
