name: quality-gates description: Understanding and passing workflow quality gates (validate, dry, pytest, ruff, typecheck)

Quality Gates Skill

Use this skill to understand what each quality gate checks and how to ensure your workflow passes all gates.

Default Gates

1. validate - Structural Validation

What it checks:

• run.py exists and is valid Python
• PEP 723 metadata is present (# /// script)
• Required dependencies are declared (pydantic, rich)
• BaseWorkflow is subclassed
• run() method is implemented
• Imported tools exist in tools/ directory

Common failures:

Copy✗ Missing PEP 723 metadata block
✗ run.py must subclass BaseWorkflow
✗ Workflow class must implement run() method
✗ Tool not found: yahoo_finance (imported from tools.yahoo_finance)

How to fix:

• Add PEP 723 block at top of run.py
• Ensure class inherits from BaseWorkflow[ParamsType]
• Implement def run(self) -> int: method
• Create missing tools in tools/ directory

2. dry - Dry Run

What it checks:

• Workflow executes with mock data (no real API calls)
• dry_run.py exists and provides mocks
• No crashes or unhandled exceptions
• Returns exit code 0

Common failures:

Copy✗ dry_run.py not found
✗ KeyError: 'api_key' (accessing env var in dry run)
✗ ConnectionError: API not available (real network call in dry run)

How to fix:

• Create dry_run.py with mock functions
• Replace all external calls with mocks
• Use DryRunContext to log mock behavior
• Test locally: raw run workflow --dry

Optional Gates

3. pytest - Unit Tests

What it checks:

• All tests in test.py pass
• No test failures or errors

Enable in .raw/config.yaml:

Copybuilder:
  gates:
    optional:
      pytest:
        command: "pytest test.py -v"
        timeout_seconds: 60

Common failures:

Copy✗ AssertionError: Expected 0 but got 1
✗ ModuleNotFoundError: No module named 'workflow_name'

How to fix:

• Write tests that match actual behavior
• Import workflow class correctly
• Run pytest locally to debug

4. ruff - Linting & Formatting

What it checks:

• Code follows Python style guide
• No unused imports
• Consistent formatting

Enable in .raw/config.yaml:

Copybuilder:
  gates:
    optional:
      ruff:
        command: "ruff check . && ruff format . --check"
        timeout_seconds: 30

Common failures:

Copy✗ F401 'sys' imported but unused
✗ E501 Line too long (92 > 88 characters)

How to fix:

• Remove unused imports
• Run ruff format . to auto-format
• Run ruff check --fix . for auto-fixes

5. typecheck - Type Validation

What it checks:

• Type hints are correct
• No type mismatches

Enable in .raw/config.yaml:

Copybuilder:
  gates:
    optional:
      typecheck:
        command: "mypy run.py"
        timeout_seconds: 60

Gate Failure Strategy

When gates fail:

1. Read the error message carefully

   • Gate output is saved to .raw/builds/<build_id>/logs/<gate>.log
   • Contains full error details

2. Fix one gate at a time

   • Start with validate (structural issues)
   • Then dry (runtime issues)
   • Finally optional gates (quality issues)

3. Test locally before rebuilding

   Copyraw validate workflow-id  # Check validation
   raw run workflow-id --dry # Check dry run
   pytest test.py            # Check tests
   

4. Common patterns:

   • validate fails → Fix run.py structure
   • dry fails → Add/fix mocks in dry_run.py
   • pytest fails → Fix tests or implementation
   • ruff fails → Run auto-formatters
   • typecheck fails → Add/fix type hints

Example: Fixing Validation Failure

Copy✗ Validation failed
Errors:
  • Missing PEP 723 metadata block (# /// script)
  • Tool not found: yahoo_finance (imported from tools.yahoo_finance)

Steps to fix:

1. Add PEP 723 block to run.py:

   Copy#!/usr/bin/env python3
   # /// script
   # requires-python = ">=3.10"
   # dependencies = ["pydantic>=2.0", "rich>=13.0", "yfinance>=0.2"]
   # ///
   

2. Create tools/yahoo_finance/:

   Copymkdir -p tools/yahoo_finance
   touch tools/yahoo_finance/__init__.py
   # Create tools/yahoo_finance/tool.py
   

3. Validate again:

   Copyraw validate workflow-id
