lint

Linting

Run the project's linter/formatter — detect it, don't assume a toolchain.

Detection

Prefer a task the project already defines, then fall back to the ecosystem tool:

Ecosystem	Check	Fix
Node	package.json lint (eslint/biome)	lint:fix
Python	ruff check / flake8	ruff check --fix
Go	golangci-lint run / gofmt -l	gofmt -w
Rust	cargo clippy / cargo fmt --check	cargo fmt
else	Makefile / CI lint target	—

Workflow

1. Detect the linter (project task first, then ecosystem default)
2. Run the check command
3. For fixes: run the fix variant (only when requested)
4. Report file:line references for all errors

Rules

• Prefer the project's defined task over a raw tool call
• Never invent a linter the project doesn't use

Error Handling

• If no linter or task found → report which config/task is expected and stop
• If the linter exits with parse errors → report each file-level parse error separately with file:line
• If the linter config is missing → report which config is expected and stop
