Custom Quality Check

Purpose

This is a project-specific custom skill called by the Builder workflow to enforce code quality standards. It runs linting and quality checks specific to this project (claudecode_webui).

Generic workflow skills invoke this skill if it exists; if absent, the quality check step is skipped.

When Called

The Builder invokes this skill from its working directory (the worktree) after implementation, providing the list of changed files.

Input

• changed_files: List of files modified (from git diff --name-only)

Quality Checks

Ruff Linting (Python files)

Run Ruff on modified Python files only:

# Get changed Python files
CHANGED_PY=$(git diff --name-only --diff-filter=AM | grep '\.py$')

# Run Ruff with auto-fix on changed files
if [ -n "$CHANGED_PY" ]; then
    uv run ruff check --fix $CHANGED_PY
fi

Rules

• New code MUST NOT introduce new violations
• Changed code SHOULD fix existing violations when touched
• Auto-fix safe violations in modified files
• Line length: 100 characters
• Target Python: 3.11+

Important

• Do NOT run uv run ruff check --fix src/ on the entire codebase
• Only lint files that were actually modified to avoid unrelated changes

Usage by Generic Skills

The Builder workflow calls this skill like:

Invoke custom-quality-check skill with changed_files

The skill runs project-specific quality checks in the Builder's working directory. If this skill does not exist, the generic workflow skips the quality check step.
