"""
End-to-end tests for bootstrap skill feature (PR #249)

Tests verify:
1. Bootstrap script creates proper skill structure
2. Generated SKILL.md is valid and usable
3. Skill is installable in isolated virtual environment
4. Output works with all platform adaptors
5. Error cases handled gracefully

Coverage: 8-12 tests
Execution time: Fast tests ~2-3 min, Full tests ~5-10 min
Requires: Python 3.10+, bash, uv

Run fast tests:
    pytest tests/test_bootstrap_skill_e2e.py -v -k "not venv"

Run full suite:
    pytest tests/test_bootstrap_skill_e2e.py -v -m "e2e"

Run with venv tests:
    pytest tests/test_bootstrap_skill_e2e.py -v -m "venv"
