# RFC: perf-sentinel Plugin
|
||||
|
||||
**Status:** Proposal
|
||||
**Created:** 2026-01-28
|
||||
**Author:** Claude Code Analysis
|
||||
**Priority:** Medium
|
||||
**Estimated Effort:** 2 sprints
|
||||
**Depends On:** None (can be implemented independently)
|
||||
|
||||
---
|
||||
|
||||
## Executive Summary
|
||||
|
||||
Create a new plugin dedicated to performance profiling, benchmarking, and optimization of the plugin/hook ecosystem. This plugin automates the kind of manual analysis performed in RFC-Hook-Efficiency-Improvements, providing continuous monitoring and regression detection.
|
||||
|
||||
---
|
||||
|
||||
## Motivation
|
||||
|
||||
### Problem Statement
|
||||
|
||||
1. **Manual analysis is time-consuming** - The hook efficiency review required reading 15+ files and manual assessment
|
||||
2. **No regression detection** - Performance degradations go unnoticed until they become painful
|
||||
3. **No baseline tracking** - We don't know if changes improve or worsen performance
|
||||
4. **Optimization suggestions require expertise** - Not all users can identify inefficiencies
|
||||
|
||||
### Goals
|
||||
|
||||
1. Automate performance audits
|
||||
2. Establish and track performance baselines
|
||||
3. Detect regressions before they accumulate
|
||||
4. Provide actionable optimization recommendations
|
||||
5. Keep monitoring overhead minimal (< 10ms per session)
|
||||

## Feature Specifications
|
||||
|
||||
### Command: `/perf-audit`
|
||||
|
||||
**Purpose:** Automated performance audit (what we did manually for hooks)
|
||||
|
||||
**Behavior:**
|
||||
1. Enumerate all hooks across all plugins
|
||||
2. Measure execution time of each hook (dry run with mock input)
|
||||
3. Analyze hook scripts for known anti-patterns
|
||||
4. Check for redundant operations across hooks
|
||||
5. Generate report with recommendations
|
||||
|
||||
**Output Example:**
|
||||
```

|
||||
HOOK ANALYSIS (16 hooks across 12 plugins)
|
||||
|
||||
SessionStart Hooks (7):
|
||||
┌─────────────────────────────────┬──────────┬─────────────────────────────┐
|
||||
│ Hook │ Time │ Concerns │
|
||||
├─────────────────────────────────┼──────────┼─────────────────────────────┤

|
||||
│ viz-platform (inline echo) │ 2ms │ ⚠️ No value │
|
||||
└─────────────────────────────────┴──────────┴─────────────────────────────┘
|
||||
Total SessionStart overhead: 1,004ms
|
||||
|
||||
PostToolUse Hooks (4):
|
||||
┌─────────────────────────────────┬──────────┬─────────────────────────────┐
|
||||
│ Hook │ Time │ Concerns │
|
||||
├─────────────────────────────────┼──────────┼─────────────────────────────┤

|
||||
│ doc-guardian/notify.sh │ 12ms │ OK │
|
||||
└─────────────────────────────────┴──────────┴─────────────────────────────┘
|
||||
Avg PostToolUse overhead: 50ms per edit
|
||||
|
||||
REDUNDANCY ANALYSIS
|
||||
- MCP venv check: duplicated in 3 hooks
|
||||
- Git remote check: duplicated in 2 hooks
|
||||
- JSON parsing: 8 independent implementations
|
||||
|
||||
ANTI-PATTERNS DETECTED
|
||||
1. HTTP calls in SessionStart (2 hooks)
|
||||
2. Full project find in PostToolUse (1 hook)
|
||||
3. Broad Bash matcher triggering on all commands (2 hooks)
|
||||
|
||||
RECOMMENDATIONS (see /perf-optimize for details)
|
||||
1. Consolidate SessionStart hooks → est. -400ms
|
||||
2. Add cooldown to project-hygiene → est. -50ms/edit
|
||||
3. Remove viz-platform echo hook → est. -2ms
|
||||
4. Add early-exit to git-flow hooks → est. -20ms/cmd
|
||||
|
||||
Overall Score: 62/100 (Needs Improvement)
|
||||
```
|
||||
|
||||
**Anti-patterns to detect:**
|
||||
| Pattern | Detection Method | Severity |
|
||||
|---------|------------------|----------|
|
||||
| HTTP calls in SessionStart | grep for `curl`, `wget`, API URLs | High |
|
||||
| Full project `find` | grep for `find "$PROJECT"` or `find .` | High |
|
||||
| Python spawn for simple tasks | grep for `python` in shell scripts | Medium |
|
||||
| No early exit | Check if script bails out quickly for irrelevant input | Medium |
|
||||
| Broad Bash matcher | Check hooks.json for `"matcher": "Bash"` | Medium |
|
||||
| Duplicate logic | Compare function signatures across hooks | Low |
|

||||
+ data-platform/schema-diff-check.sh (PostToolUse)
|
||||
|
||||
Modified hooks:
|
||||
~ projman/startup-check.sh → +12ms (added version check)
|
||||
|
||||
Recommendation:
|
||||
Review data-platform SessionStart hook - consider lazy loading
|
||||
Run /perf-optimize for detailed suggestions
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### Command: `/benchmark-hooks`
|
||||
|
||||
**Purpose:** Detailed benchmarking of specific hooks

||||
2. Provide statistical analysis
|
||||
3. Optional: use hyperfine if available
|
||||
|
||||
**Parameters:**
|
||||
- `HOOK_PATH` - Path to specific hook, or "all"
|
||||
- `--runs N` - Number of runs (default: 20)
|
||||

|
||||
|
||||
**Output Example:**
|
||||
```
|
||||
[perf-sentinel] Hook Benchmark: projman/startup-check.sh
|
||||
========================================================
|
||||
|
||||
Configuration:
|
||||
Runs: 20 (+ 3 warmup)
|
||||
Input: mock SessionStart payload
|
||||
Tool: hyperfine (detected)
|
||||
|
||||
Results:
|
||||
Mean: 342.3ms
|
||||
StdDev: 28.1ms
|
||||
Min: 298ms
|
||||
Max: 412ms
|
||||
P50: 338ms
|
||||
P95: 389ms
|
||||
|
||||
Time Breakdown (via strace):
|
||||
Network I/O: 267ms (78%) ← Gitea API calls

|
||||
|
||||
Recommendation:
|
||||
Network calls dominate. Consider:
|
||||
- Caching API responses
|
||||
- Making calls async/lazy
|
||||
- Reducing call frequency
|
||||
```
|
||||
|
||||

Based on audit from 2026-01-28 12:00
|
||||
|
||||
PRIORITY 1 - High Impact, Low Effort
|
||||
────────────────────────────────────
|
||||
1. Remove viz-platform SessionStart hook
|
||||
File: plugins/viz-platform/hooks/hooks.json
|
||||
Action: Delete the hook (provides no value)
|
||||
Impact: -2ms startup
|
||||
Effort: 1 line change
|
||||
|
||||
2. Make clarity-assist opt-in
|
||||

||||
Action: Change default from true to false
|
||||
Impact: -50ms per prompt (when disabled)
|
||||
Effort: 1 line change
|
||||
|
||||
PRIORITY 2 - High Impact, Medium Effort
|
||||
───────────────────────────────────────
|
||||
3. Add early-exit to git-flow hooks
|
||||
Files: plugins/git-flow/hooks/branch-check.sh
|
||||
plugins/git-flow/hooks/commit-msg-check.sh
|
||||
Action: Check for "git" in command before full parsing
|
||||
Impact: -20ms per non-git bash command
|
||||
Effort: ~10 lines each
|
||||
|
||||
4. Add cooldown to project-hygiene
|
||||
File: plugins/project-hygiene/hooks/cleanup.sh
|
||||
Action: Skip if ran in last 5 minutes
|
||||
Impact: -89ms per edit (when cooling down)
|
||||
Effort: ~15 lines
|
||||
|
||||
PRIORITY 3 - High Impact, High Effort
|
||||
─────────────────────────────────────
|
||||
5. Consolidate SessionStart hooks
|
||||
Action: Create central dispatcher, remove individual hooks
|
||||
Impact: -400ms startup (estimated)
|
||||
Effort: New architecture, ~200 lines
|
||||
|
||||
6. Create shared hook library
|
||||
Action: Extract common JSON parsing, path filtering
|
||||
Impact: Reduced maintenance, consistent behavior
|
||||
Effort: ~100 lines library + refactor all hooks
|
||||
|
||||
ESTIMATED TOTAL IMPACT
|
||||
──────────────────────
|
||||
If all optimizations implemented:
|
||||
Session startup: 487ms → ~180ms (63% reduction)
|
||||
Edit cycle: 156ms → ~60ms (62% reduction)
|
||||
|
||||
Implementation order recommendation:
|
||||
Sprint 1: Items 1-4 (quick wins)
|
||||
Sprint 2: Items 5-6 (architecture)
|
||||
```

### Hook: Session Metrics (Lightweight)
|
||||
|
||||
**File:** `hooks/hooks.json`
|
||||
```json
|
||||
{
|
||||
"hooks": {
|
||||
"SessionEnd": [
|
||||
{
|
||||
"type": "command",
|
||||
"command": "${CLAUDE_PLUGIN_ROOT}/hooks/session-metrics.sh"
|
||||
}
|
||||
]
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Design Principles:**
|
||||
1. **SessionEnd only** - No per-tool overhead
|
||||
2. **Fast execution** - Must complete in < 10ms
|
||||
3. **Minimal I/O** - Single file write
|
||||
4. **No network** - Never make HTTP calls
|
||||
|
||||
**Script:** `hooks/session-metrics.sh`
|
||||
```bash
|
||||
#!/bin/bash
|
||||
# perf-sentinel session metrics collector
|
||||
# MUST be lightweight - runs on every session end
|
||||
|
||||
# Metrics directory
|
||||
METRICS_DIR="$HOME/.cache/claude-plugins/perf-sentinel/sessions"
|
||||
TODAY=$(date +%Y-%m-%d)
|
||||
mkdir -p "$METRICS_DIR/$TODAY" 2>/dev/null
|
||||
|
||||
# Collect only what's cheap to measure
|
||||
SESSION_ID="${CLAUDE_SESSION_ID:-$(date +%s)}"
|
||||
DURATION="${CLAUDE_SESSION_DURATION_MS:-0}"
|
||||
|
||||
# Single atomic write
|
||||
cat > "$METRICS_DIR/$TODAY/$SESSION_ID.json" << EOF
|
||||
{"ts":"$(date -Iseconds)","dur":$DURATION,"id":"$SESSION_ID"}
|
||||
EOF
|
||||
|
||||
exit 0
|
||||
```
|
||||

|
||||
|
||||

|
||||
|
||||
**Model:** `sonnet` (good balance of speed and analysis quality)
|
||||
|
||||
---
|
||||
|
||||
### Agent: benchmark-runner
|
||||
|
||||
**Purpose:** Execute systematic benchmarks

## Implementation Plan
|
||||
|
||||
### Phase 1: Core Infrastructure (Sprint 1)
|
||||
1. Create plugin structure
|
||||
2. Implement `/perf-audit` command
|
||||
3. Implement lightweight SessionEnd hook
|
||||
4. Create scripts/lib/ utilities
|
||||
|
||||
### Phase 2: Baseline System (Sprint 1)
|
||||
5. Implement `/perf-baseline` command
|
||||
6. Implement `/perf-compare` command
|
||||
7. Set up data storage structure
|
||||
|
||||
### Phase 3: Advanced Features (Sprint 2)
|
||||
8. Implement `/benchmark-hooks` command
|
||||
9. Implement `/perf-optimize` command
|
||||
10. Create perf-analyzer agent
|
||||
11. Add external tool integration
|
||||
|
||||
### Phase 4: Polish (Sprint 2)
|
||||
12. Add configuration system
|
||||
13. Create README and documentation
|
||||
14. Add to marketplace.json
|
||||
15. Integration testing
|
||||

## Success Metrics
|
||||
|
||||
| Metric | Target |
|
||||
|--------|--------|
|
||||
| Audit execution time | < 5 seconds |
|
||||
| Metrics hook overhead | < 10ms |
|
||||
| Regression detection accuracy | > 90% |
|
||||
| False positive rate | < 5% |
|
||||

|
||||
|
||||
## Risks and Mitigations
|
||||
|
||||
| Risk | Mitigation |
|
||||
|------|------------|
|
||||
| Metrics collection adds overhead | SessionEnd only, < 10ms budget |
|
||||
| Benchmark results vary by system | Statistical analysis, warmup runs |
|
||||
| External tools not available | Graceful fallback to built-in |
|
||||
| Storage grows unbounded | Retention policy, auto-cleanup |
|
||||
|
||||

|
||||
|
||||
## Open Questions
|
||||
|
||||
1. Should `/perf-audit` run automatically on version changes?
|
||||
2. Should we integrate with CI/CD for automated regression testing?
|
||||
3. Should baseline comparisons be part of `/sprint-close`?
|
||||
4. Should we track memory usage in addition to time?
