Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00032 | $0.02263 |
| Opus 5 | $0.00016 | $0.01131 |
| Sonnet 5 | $0.00006 | $0.00453 |
| Haiku 4.5 | $0.00003 | $0.00226 |
Grade A, and why
application-performance-performance-optimization scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
92% identical to application-performance-performance-optimization — 7 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Optimize application performance end-to-end using specialized performance and optimization agents:
[Extended thinking: This workflow orchestrates a comprehensive performance optimization process across the entire application stack. Starting with deep profiling and baseline establishment, the workflow progresses through targeted optimizations in each system layer, validates improvements through load testing, and establishes continuous monitoring for sustained performance. Each phase builds on insights from previous phases, creating a data-driven optimization strategy that addresses real bottlenecks rather than theoretical improvements. The workflow emphasizes modern observability practices, user-centric performance metrics, and cost-effective optimization strategies.]
Use this skill when
- Coordinating performance optimization across backend, frontend, and infrastructure
- Establishing baselines and profiling to identify bottlenecks
- Designing load tests, performance budgets, or capacity plans
- Building observability for performance and reliability targets
Do not use this skill when
- The task is a small localized fix with no broader performance goals
- There is no access to metrics, tracing, or profiling data
- The request is unrelated to performance or scalability
Instructions
- Confirm performance goals, constraints, and target metrics.
- Establish baselines with profiling, tracing, and real-user data.
- Execute phased optimizations across the stack with measurable impact.
- Validate improvements and set guardrails to prevent regressions.
Safety
- Avoid load testing production without approvals and safeguards.
- Roll out performance changes gradually with rollback plans.
Phase 1: Performance Profiling & Baseline
1. Comprehensive Performance Profiling
- Use Task tool with subagent_type="performance-engineer"
- Prompt: "Profile application performance comprehensively for: $ARGUMENTS. Generate flame graphs for CPU usage, heap dumps for memory analysis, trace I/O operations, and identify hot paths. Use APM tools like DataDog or New Relic if available. Include database query profiling, API response times, and frontend rendering metrics. Establish performance baselines for all critical user journeys."
- Context: Initial performance investigation
- Output: Detailed performance profile with flame graphs, memory analysis, bottleneck identification, baseline metrics
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

application-performance-performance-optimization is a skill published in the GitHub repository pinkpixel-dev/skills-collection-1 (7 stars, last pushed 27d ago), licensed Apache-2.0. It adds 32 tokens to every session and 2,263 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 92% identical to application-performance-performance-optimization, differing in 7 lines, and is treated as a copy.
