code-review-performance SKILL.md skillA
code-review-performance from eltmon/overdeck is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add eltmon/overdeck/code-review-performance@git:20260714.8d8cc01Pins git:20260714.8d8cc01 in mdr.lock. Pin the fingerprint instead.

Deep performance analysis focusing on algorithms and resources.
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 Review
## Algorithm Complexity
- Identify O(n^2) or worse algorithms
- Look for unnecessary iterations
- Check for opportunities to use better data structures
## Database/API Patterns
- N+1 query detection
- Missing indexes (check query patterns)
- Unbounded queries (missing LIMIT)
- Connection pool exhaustion risks
## Memory & Resources
- Memory leaks (unclosed resources)
- Unbounded caches or buffers
- Large object allocations in loops
## Concurrency
- Lock contention hotspots
- Blocking operations in async contexts
- Thread pool exhaustion
## Blocking Operations (CRITICAL for Node.js)
- **execSync/spawnSync** - These BLOCK the event loop and cause UI freezes
- Search for: `execSync`, `spawnSync`, `readFileSync` in hot paths
- **ALWAYS flag as HIGH IMPACT** - causes perceived hangs and latency spikes
**Fix pattern to recommend:**
```typescript
// Replace execSync with async version
import { exec } from 'child_process';
import { promisify } from 'util';
const execAsync = promisify(exec);
const { stdout } = await execAsync('command here');
```
Common offenders in this codebase:
- `tmux capture-pane` / `tmux send-keys` / `tmux has-session`

How to install
mdr add eltmon/overdeck/code-review-performance@sha256:0a09d83f53536184The line at the top of this page pins the label git:20260714.8d8cc01, 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.
