language-linting-skill
"Per-language linting rules reference — Python Ruff, JS/TS ESLint, Java Checkstyle/PMD/SpotBugs, C# dotnet format/Roslyn/StyleCop: rules, configs, error guidance. Triggers: ruff rules, eslint config, checkstyle. Loaded by linting-workflow-skill and linting-subagent (the executor); gate semantics live in verification-loop-skill."

What I do
Per-language lint execution and error resolution on top of linting-workflow-skill (which owns the generic detect→fix loop and delegation). This file maps languages → linters, detection commands, and the fix guidance that actually needs saying.
When to use me
Linting a polyglot codebase; decoding a specific linter error; configuring lint in CI.
Language detection: file extensions + manifests (.py/pyproject → Ruff; .ts/.tsx/.js/.jsx/package.json → ESLint; .java/pom.xml|build.gradle → Checkstyle+PMD+SpotBugs; .cs/.csproj → dotnet format + Roslyn analyzers). Orchestration + subagent delegation → linting-workflow-skill.
Command matrix
| Language | Linter(s) | Commands |
|---|---|---|
| Python | Ruff | ruff check . · ruff check --fix · ruff format . (config in pyproject [tool.ruff]) |
| JS/TS | ESLint (+Prettier) | npx eslint . --ext .ts,.tsx,.js,.jsx · --fix for autofixables; package manager via lockfile (pnpm-lock/yarn.lock/package-lock); Prettier for formatting, ESLint for correctness |
| Java | Checkstyle (style) + PMD (design) + SpotBugs (bytecode bugs) | Maven: mvn checkstyle:check pmd:check spotbugs:check · Gradle: ./gradlew checkstyleMain pmdMain spotbugsMain |
| C# | dotnet format + Roslyn/StyleCop analyzers | dotnet format --verify-no-changes (CI) · dotnet format (fix); severity via .editorconfig |
House rules
- Fix semantics: autofix for mechanical issues (
--fix,ruff format); manual review for semantic findings (PMD design, SpotBugs correctness, Roslyn analyzers) — never blanket-suppress. - Zero NEW errors on changed files is the gate (pre-existing noted, not blocked) — matches
plan-execution-skill--gate semantics. - Suppressions carry a reason and scope (
// noqa: E501 # long URL in docstring), never bare// eslint-disable-next-line. - Error-code decoding: match the code to the rule family (Ruff
E/F/I/N/UP/B/SIM/C4, ESLint plugin prefixes, Checkstyle module names) and fix the pattern, not the instance. - Spring Boot: enable Bean Validation + actuator health checks as part of the lint pass config (house standard for Java services).

Removed 2026-09: per-linter config file listings, per-error-code explanation tables, package-manager detection walkthroughs, Spring/Gradle XML config dumps, worked fix transcripts — each linter's rule catalog is model-known; the matrix + fix semantics + suppression discipline are the durable content.
