Dart Skills Lint Setup Agent Skill

Setting up Skill Validation with skills_lint

This skill covers first-time wiring of skills_lint into a

repository. For ongoing use — running the linter, interpreting

output, and writing custom rules — see the

dart-skills-lint-validation

skill. For copy-pasteable CI workflow and pre-commit hook recipes,

see the Recipes section of the README.

Steps

• Add skills_lint as a dev_dependency.

   dev_dependencies:
     skills_lint: ^0.5.0

Isolate the dependency in a tool/ package when you can,

instead of putting it on the root pubspec.yaml — keeps the

linter's deps out of your runtime closure. If you must add it

to multiple pubspec.yaml files, ensure the ref: (commit

hash) is identical across all of them so resolution doesn't

diverge.

• Create skills_lint.yaml at the repository root so both

the CLI and any embedded test invocation share the same config:

   skills_lint:
     rules:
       check-relative-paths: error
       check-trailing-whitespace: error
     directories:
       - path: ".agents/skills"

Rules enabled by default — check-absolute-paths,

valid-yaml-metadata, invalid-skill-name,

description-too-long — only need to be listed if you want to

change their severity. See RULES.md for the

full list.

• Generate a baseline if you're integrating into a repository

with pre-existing skills that have legacy violations you don't

want to fix immediately:

   dart run skills_lint:cli --skills-directory=.agents/skills --generate-baseline

This writes the current set of failures into an ignore file so

the next run exits clean. New violations introduced after the

baseline still surface as errors.

• Wire it into CI. Use the

GitHub Actions recipe from the README

verbatim, or follow the

pre-commit hook recipe below it.

When you're done
