Updated: Oct 2026; last repo commit

This skill gives Claude two workflows. The first runs the analyzer with the analyze_files MCP tool if your agent has it, or dart analyze <target_directory> otherwise. The second previews fixes with dart fix --dry-run, applies them with dart fix --apply, runs dart format ., then analyzes again. It triggers during development and before committing changes.

The skill also holds rules for analysis_options.yaml: an included rule set, strict casts, linter rules, formatter settings and plugins. It adds ways to suppress a warning by file, line or pubspec.yaml. It is one file and bundles no scripts. dart fix --apply and dart format . change your source files.

Good for

Dart and Flutter developers who want lint and analyzer issues cleaned up
Teams who want analysis run before every commit
Anyone setting up strict type checks in analysis_options.yaml

Questions

What does dart-run-static-analysis do?

It makes Claude run the Dart analyzer, then preview and apply automatic fixes with dart fix, format the code, and analyze again. It also tells Claude how to configure analysis_options.yaml.

How do I install it?

Use the install box at the top of this page. The dart-lang/skills README also gives one command that installs every skill in the repo into the standard .agents/skills folder, if you want the whole set.

Does it need the Dart MCP tools?

No. The steps use the analyze_files, dart_fix and dart_format MCP tools if available, and give the dart analyze, dart fix and dart format commands as the other route.

Is it safe to use?

dart fix --apply and dart format . edit your files, so run it in a git repository and review the diff. The skill tells Claude to preview with dart fix --dry-run and to check the proposed fixes first.

How is it different from dart-fix-runtime-errors?

dart-run-static-analysis is about running the analyzer and automated fixes, plus analysis_options.yaml setup. dart-fix-runtime-errors, another skill in the same Dart repo, is a longer workflow on fixing type, null-safety and override errors by hand after dart fix, ending with dart test. See its SKILL.md for the steps.
