profile-dart-code SKILL.md skillB

profile-dart-code from kevmoo/dash_skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add kevmoo/dash_skills/profile-dart-code@git:20260913.6c39005

Pins git:20260913.6c39005 in mdr.lock. Pin the fingerprint instead.

Profile Dart command-line applications using the VM Service protocol to capture CPU samples and identify performance bottlenecks. Helps agents automate CPU profiling, generate function call breakdown summaries, and export JSON profiles without a browser or DevTools.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Dart CPU Profiling

Guidelines and automated tools for capturing CPU profiles and identifying
bottlenecks in Dart command-line applications.

## When to use this skill

- When asked to profile, optimize, or benchmark CPU execution of a Dart script
  or CLI tool.
- When investigating hot loops, heavy function calls, or unexpected execution
  overhead.

### When NOT to use (Abstention Guardrails)

Do NOT profile using this skill when:

- **Pure I/O-Bound Bottlenecks**: The performance bottleneck is network latency,
  database queries, or disk I/O wait rather than CPU execution.
- **Flutter UI Applications**: The target is a Flutter application requiring
  frame profiling, raster thread inspection, or widget rebuild tracking (use
  Flutter DevTools or `widget_inspector`).
- **Short-Lived Micro-Benchmarks**: Micro-benchmarks running for only a few
  milliseconds where VM warmup and sampling overhead skew results (use
  `package:benchmark_harness` or `package:bench_press` instead).
- **Target Does Not Run Cleanly**: If the target script fails to compile or
  crashes on startup, fix functional bugs before attempting CPU profiling.

How to install

The exact contents, by fingerprint

mdr add kevmoo/dash_skills/profile-dart-code@sha256:dfbd8a7d1480c2f9

The line at the top of this page pins the label git:20260913.6c39005, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
