# Free sample — Performance Profiler Optimizer

**Skill ID:** `performance-profiler-optimizer`  
**Full unlock:** $6.49 USDC via x402 on Base  
**Challenge:** https://lvlltd.com/api/pay?skill=performance-profiler-optimizer  
**Outline JSON:** https://lvlltd.com/skills/performance-profiler-optimizer/outline.json

## Summary

Measure first, then optimize: profile CPU/memory/latency hotspots, pick highest ROI fixes, and prove gains with before/after metrics — GPU paths when relevant.

## When to use

- Slow endpoints or agents
- Need evidence for perf PR
- GPU/CPU tradeoffs

## Decision criteria (buy vs skip)

- You need this when: Slow endpoints or agents
- You get capability: Define SLOs
- Budget fits: full unlock is $6.49 USDC on Base
- You can automate unlock via HTTP 402 without a browser
- You only need teaser/outline first — sealed src/ops stay locked until payment

## Outline (preview)

1. Define SLOs
2. Profile
3. Rank hotspots
4. Implement minimal fix
5. Re-measure

## Capabilities (preview)

- Define SLOs
- Profile
- Rank hotspots
- Implement minimal fix

## What you get after payment

- SKILL.md (teaser public)
- agent-install.json (public meta)
- src/index.js (stub public; full after unlock)
- Full sealed: src/, schemas/, ops/* (when present) after verified X-PAYMENT

# Performance Profiler Optimizer

Measure first, then optimize: profile CPU/memory/latency hotspots, pick highest ROI fixes, and prove gains with before/after metrics — GPU paths when relevant.

## Quick Reference
| Item | Value |
|------|-------|
| Category | Coding |
| Unlock | $6.49 USDC (x402 Base) |
| Triggers | performance profiler, optimize latency, hotspot analysis, /performance-profiler-optimizer |

## When to use
- Slow endpoints or agents
- Need evidence for perf PR
- GPU/CPU tradeoffs

## Core workflow
1. Capture baseline
2. Profile representative load
3. Rank by time/cost
4. Optimize top 1-3
5. Re-measure

## Procedures (non-obvious)
No optimizing without baseline. Prefer algorithmic fixes over micro-tweaks first.
Super NVIDIA path for batch compute; always leave CPU fallback.

## Edge cases
- Prod-only load use synthetic + scrubbed samples
- Flaky benchmarks warm up first

## Failure modes
- Premature micro-optimization
- No before/after numbers

## Verification
- Baseline + after metrics recorded
- SLO improved or residual explained

## Artifact outputs
- `profile-report.md`
- `before-after.json`

## Super Alignment Contract
- Scalable oversight method: process supervision + human+AI critique before high-blast actions
- Corrigibility guarantees: shutdown, steerability, non-deception; operator may abort mid-run
- Value model: Partnership Agreement + 5 Behavioral Protocols
- Drift detection: flag invented evidence, skipped verification, or revenue-over-truth optimization
- Red-team surface: prompt injection via retrieved content, tool-result poisoning, g
