Run Code Quality Tool

Goal

Run formatting checks and static analysis for Python changes under lib/jnpr/junos.

Required Workflow

1) Install required code-quality tools

Install pylint and ruff before running checks:

• python3 -m pip install pylint ruff

2) Detect changed Python source files

Collect changed files under lib/jnpr/junos and keep only .py files.

Preferred commands:

• git diff --name-only -- lib/jnpr/junos | grep -E '\\.py$'
• git diff --name-only --cached -- lib/jnpr/junos | grep -E '\\.py$'

3) Run ruff format check for diff files

Run formatting check for only changed Python files under lib/jnpr/junos:

• CHANGED=$( (git diff --name-only -- lib/jnpr/junos; git diff --name-only --cached -- lib/jnpr/junos) | grep -E '\\.py$' | sort -u )
• if [ -n "$CHANGED" ]; then echo "$CHANGED" | xargs -I{} ruff format --check "{}"; else echo "No changed Python files under lib/jnpr/junos"; fi

4) Run pylint for changed files under lib/jnpr/junos

Run pylint for only changed Python files first:

• CHANGED=$( (git diff --name-only -- lib/jnpr/junos; git diff --name-only --cached -- lib/jnpr/junos) | grep -E '\\.py$' | sort -u )
• if [ -n "$CHANGED" ]; then pylint $CHANGED --exit-zero; else echo "No changed Python files under lib/jnpr/junos"; fi

5) Optional full ruff format for all Python files

If requested, run ruff format across all tracked Python files:

• git ls-files '*.py' | xargs -I{} ruff format "{}"

6) Optional full pylint command

If requested, run the broader pylint command:

• pylint $(git ls-files '*.py' | grep -vE '^(docs/|build/|tests/|samples/|setup.py|versioneer.py)') --exit-zero

Output Contract

When this skill is invoked, the final response must include:

1. Changed Python files detected under lib/jnpr/junos.
2. ruff format --check result for changed files.
3. pylint result for changed files.
4. If optional full ruff format was run, include that result separately.
5. If full pylint was run, include that result separately.
