What it does
Providing Performance Optimization Advice is an agent skill from foryourhealth111-pixel/Vibe-Skills. Produce a prioritized performance-optimization roadmap across frontend, backend, and infrastructure. Use as an explicit/manual helper after bottlenecks are known or suspected, not as the owner of regression detection, profiling capture, or test execution.
Its SKILL.md is about 390 tokens, which your agent loads only when the skill is triggered. The skill folder holds 9 other files, including scripts, reference files and assets (for example `assets/README.md`, `references/README.md` and `scripts/README.md`).
It sits in Development, covering Performance optimization. The repository describes itself as: Intelligent Skill routing and workflow orchestration for AI agents — +21.12 pp reward, −29.6% tokens on SkillsBench with DeepSeekV4Flash-VE. The licence is MIT.
When your agent uses it
- Tasks that involve Performance optimization
Example prompts
- “/providing-performance-optimization-advice”
Requirements
- Python 3
- Pre-approved tools (allowed-tools): Read, Write, Edit, Grep, Glob, Bash(profiling:*), Bash(analysis:*)
What it can do on your machine
Read from SKILL.md and the folder at commit ddcaa2a. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
ReadWriteEditGrepGlobBash(profiling:*)Bash(analysis:*)
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 4 files in scripts/ (Python), which the agent can run.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Providing Performance Optimization Advice loads about 391 tokens when it runs, and up to ~609 if it reads all its reference files. Until then it costs about 74 tokens; SKILL.md has 122 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

Performance Optimization Advisor
Positioning
Treat this skill as an explicit/manual advisor for prioritizing optimization work.
When to Use
Use this skill when:
- Prioritizing known or suspected performance bottlenecks from existing logs, traces, benchmarks, or user reports.
- Get recommendations for improving website loading speed.
- Optimize database query performance.
- Improve API response times.
- Reduce infrastructure costs.
Not For / Boundaries
- Build-to-build regression detection: use
detecting-performance-regressions - Raw benchmark execution or profiling capture: use
performance-testing - Test-result packaging for QA audiences: use
generating-test-reports
Typical Outputs
- A ranked optimization backlog by impact and effort
- Concrete hotspots by layer: frontend, backend, infra, or database
- Suggested validation steps to prove the optimization worked
