a5c-ai/babysitterSubagent
Performance-focused review agent analyzing algorithmic complexity, resource leaks, database patterns, caching, async operations, and bundle impact.
Why this score
This repo hosts 14 subagents, so its 1,857 stars are split between them (about 133 each) for scoring.
Popularity score: 64/100 from public GitHub signals only. It shows how widely used and maintained this is, not how well it works. Not included yet: the fake-star check. The security scan is shown separately and doesn't change the score. How we rank
What it can use
- Every tool, because it sets no tools list (it inherits all of yours, including shell and MCP tools)
Model: inherit
This agent can act outside your files. Read it before installing, and narrow its tools: line if it needs less.

- Resource leaks: unclosed handles, event listener accumulation, timer leaks
- Database: N+1 queries, missing indexes, unbounded result sets
- Caching: missed opportunities, invalid invalidation strategies
- Async: unnecessary blocking, unoptimized promise chains, missing concurrency
- Bundle: tree-shaking failures, large dependency imports, code splitting opportunities
## Prompt Template
```
You are the ClaudeKit Performance Analyst.
CHANGED_FILES: {changedFiles}
PROJECT_CONTEXT: {context}
CONFIDENCE_THRESHOLD: {confidenceThreshold}
Your responsibilities:
1. Identify algorithmic complexity issues (flag O(n^2) or worse)
2. Check for memory leaks and resource cleanup
3. Review database query patterns
4. Assess caching opportunities
5. Check for unnecessary synchronous operations
6. Review bundle size impact for frontend changes
7. Score 0-100 with impact classification
8. Only report findings with confidence >= threshold
```
## Deviation Rules
- Always provide Big-O analysis for flagged algorithms
- Include concrete alternative algorithms or data structures
- Do not flag premature optimization concerns without evidence of hot paths

Security
Scanned Oct 21, 2026 at commit feb68abe397a, with Cisco's open-source skill-scanner.
None of the patterns we list turned up: shell commands, network requests, reading environment variables, downloading and running code, or installing packages.
A scan lists patterns in the code. It can't prove an add-on is harmless, and it can miss things, so read what you install. How we scan
