Capture the current frame's timing info (delta time, FPS, frame counts, runtime). Snapshot only — historical frames live in Unity's Profiler window.
Passed 21 of 22 test cases with the skill, and 7 of 22 without it.

Tokens, turns and time describe resource use, not a dollar price.
One of 14 test cases the skill fixed. Same model, same prompt, with and without the skill.
If I save my tool invocation parameters into a JSON file named args.json, what CLI flag should I pass to run-tool profiler-capture-frame?
| Checked | Without skill | With skill |
|---|---|---|
| Uses --input-file flag with JSON file argument | Missed | Passed |
The instructions your model reads when the skill loads.
Reads UnityEngine.Time fields and returns them in a single struct. This tool is intentionally a single-frame snapshot — Unity's runtime API does not expose historical frame-data outside the Profiler window.
FrameTimeMs — Time.deltaTime * 1000f.Fps — 1 / Time.deltaTime (0 when delta is zero).TotalFrameCount — Time.frameCount (includes skipped renders).RealtimeSinceStartup — Time.realtimeSinceStartup.RenderedFrameCount — Time.renderedFrameCount.Uses only built-in Unity APIs (UnityEngine.Time). No external Unity package is required.
unity-mcp-cli run-tool profiler-capture-frame --input '{
"nothing": "string_value"
}'
For complex input (multi-line strings, code), save the JSON to a file and use:
unity-mcp-cli run-tool profiler-capture-frame --input-file args.jsonOr pipe via stdin (recommended):
unity-mcp-cli run-tool profiler-capture-frame --input-file - <<'EOF' {"param": "value"} EOF
If unity-mcp-cli is not found, either install it globally (npm install -g unity-mcp-cli) or use npx unity-mcp-cli instead.
