lint

name	lint
description	Fix code style issues and ensure linting CI gates pass in S3Mock. Use when ktlint or Checkstyle violations are reported, when asked to fix formatting, or as a required final step after any code change. Runs ktlint for Kotlin source files and Checkstyle for Java and XML files.

Lint Skill

Entry Criteria

Use when ktlint/Checkstyle violations are reported, when asked to fix formatting, or when invoked as a final step by the implement, test, or refactor skill.

Tools

Tool	Target	Config	Auto-fix
ktlint	Kotlin source files	.editorconfig	Yes — make format
Checkstyle	Java source + XML files	etc/checkstyle.xml	No — fix manually per docs/JAVA.md

Execution Steps

1. make format — auto-fixes Kotlin style issues.
2. make lint — reports remaining ktlint and Checkstyle violations.
3. make sort — run if any pom.xml was added or modified during this task.
4. Fix remaining Checkstyle (Java/XML) violations manually, per docs/JAVA.md and docs/KOTLIN.md.
5. make install — confirm all linting CI gates pass before finishing.

Completion Criteria

• make format run
• make lint passes with no violations
• make sort run if any pom.xml was modified
• make install passes all CI gates
