From the author

Use when an Unreal Engine 5.8 project misses its frame rate or stutters: "optimize to 60 fps", "we run at 38 fps", CPU or GPU bound, game or render thread too long, hitches, traversal or shader stutter (PSO), GC spikes, camera-cut spikes, Lumen, Nanite, VSM, ray tracing, foliage, crowds or Niagara too expensive, async compute, stat unit, ProfileGPU, Unreal Insights, TraceQuery, snapshothitches, scalability and device profiles, dynamic resolution and TSR, streaming budgets, or proving a fix with before and after captures.

Install

Each tab says whether it installs commit d44410f, the one we checked, or the latest version.

OpenCode also looks in .agents/skills/ and ~/.agents/skills/, so use the Any agent steps.

Goose also looks in .agents/skills/ and ~/.agents/skills/, so use the Any agent steps.

Windsurf (Devin Desktop) also looks in .agents/skills/ and ~/.agents/skills/, so use the Any agent steps.

Zed also looks in .agents/skills/ and ~/.agents/skills/, so use the Any agent steps.

Roo Code also looks in .agents/skills/ and ~/.agents/skills/, so use the Any agent steps.

Factory Droid also looks in .agents/skills/ and ~/.agents/skills/, so use the Any agent steps.

Junie also looks in .agents/skills/ and ~/.agents/skills/, so use the Any agent steps.

Amp also looks in .agents/skills/ and ~/.agents/skills/, so use the Any agent steps.

No install command here reaches Kiro. Copy the skill's folder into .kiro/skills/ in your project, or ~/.kiro/skills/ for all your projects. scenario-labs/skills/skills/game-engines/unreal/scenario-unreal-performance (opens in a new tab)

Antigravity also looks in .agents/skills/, so the Any agent steps reach it with This project. For All projects, see where Antigravity looks.

Cline also looks in .claude/skills/, so the Claude Code steps reach it with This project. For All projects, see where Cline looks.

No tab for your agent? Use Any agent for OpenCode, Goose, Windsurf (Devin Desktop), Zed, Roo Code, Factory Droid, Junie and Amp. With This project, Any agent also reaches Antigravity and Claude Code reaches Cline. Kiro needs the folder copied by hand.

What it can touch

From the files and frontmatter at commit d44410f. This is how much a skill can do, not whether it is risky.

Runs shell commands
Its instructions or files give the agent commands to run on your computer.
Names web addresses
It mentions outside web addresses the agent may visit. We list them but don't follow them.
Outside links we did not follow
Bundles scripts
The folder holds code files the agent may run.

Pattern check

Pattern check: nothing flagged · commit d44410f · 29 Oct 2026

We checked every text file in this skill, at commit d44410f on 29 Oct 2026, against 45 published patterns such as download-and-run commands, hidden text and credential access. We don't run the skill, we don't read the web pages it points to, and we can't judge everything its instructions might lead an agent to do. In published tests, pattern checks like this one missed most malicious skills. Read the skill before you install it — especially anything it asks you to download or run.

Format check

Each agent reads SKILL.md a little differently. We check the file against each one's published rules; we don't run the skill in any agent.

Agent Skills specPasses with warnings
The open format from agentskills.io, held to what the strictest agents enforce, so one folder loads everywhere.
- Warning
  The body is about 5,302 tokens (approx.); the spec suggests under 5,000. B2
  Fix: Move detail into reference files that the agent reads only when needed.
- Note
  The first sentence of the description is 526 characters. Agents shorten long descriptions, so lead with the main job. D8
  Fix: Start with one short sentence that names the job.
- Note
  Reference files over 100 lines with no table of contents at the top: references/expert-notes.md (329 lines), references/gui-paths.md (125 lines) and references/procedures.md (582 lines). B5
  Fix: Add a short list of the sections at the top of each.
Claude CodePasses
Claude Code reads its own extra fields, ignores unknown ones, and still loads a skill whose frontmatter is broken, without its fields.
- Note
  The first sentence of the description is 526 characters. Agents shorten long descriptions, so lead with the main job. D8
  Fix: Start with one short sentence that names the job.
- Note
  The body is about 5,302 tokens (approx.); the spec suggests under 5,000. After compaction Claude Code keeps only the first 5,000 tokens of a skill. B2
  Fix: Move detail into reference files that the agent reads only when needed.
- Note
  Reference files over 100 lines with no table of contents at the top: references/expert-notes.md (329 lines), references/gui-paths.md (125 lines) and references/procedures.md (582 lines). B5
  Fix: Add a short list of the sections at the top of each.
Claude apps & API uploadPasses
Uploading to claude.ai or the Claude API, or packaging with Anthropic's script, accepts only the six spec fields and stops on anything else.
- Note
  The description is 526 characters. The claude.ai Help Center says 200 at most, though Anthropic's API docs and validator allow 1,024. D4
  Fix: If the claude.ai upload refuses it, trim the description to 200 characters.
- Note
  The body is about 5,302 tokens (approx.); the spec suggests under 5,000. Anthropic's guidance says the same. B2
  Fix: Move detail into reference files that the agent reads only when needed.
- Note
  Reference files over 100 lines with no table of contents at the top: references/expert-notes.md (329 lines), references/gui-paths.md (125 lines) and references/procedures.md (582 lines). B5
  Fix: Add a short list of the sections at the top of each.
OpenAI (Codex & API)Passes
Codex finds SKILL.md by its exact name and needs a description; OpenAI's Skills API checks the frontmatter against the spec and caps uploads.
- Note
  The first sentence of the description is 526 characters. Agents shorten long descriptions, so lead with the main job. D8
  Fix: Start with one short sentence that names the job.
