# Continuous Learning - Session Evaluator
# Runs on Stop hook to extract reusable patterns from Claude Code sessions
#
# Why Stop hook instead of UserPromptSubmit:
# - Stop runs once at session end (lightweight)
# - UserPromptSubmit runs every message (heavy, adds latency)
#
# Hook config (in ~/.claude/settings.json):
# {
#   "hooks": {
#     "Stop": [{
#       "matcher": "*",
#       "hooks": [{
#         "type": "command",
#         "command": "~/.claude/skills/continuous-learning/evaluate-session.sh"
#       }]
#     }]
#   }
# }
#
# Patterns to detect: error_resolution, debugging_techniques, workarounds, project_specific
# Patterns to ignore: simple_typos, one_time_fixes, external_api_issues
# Extracted skills saved to: ~/.claude/skills/learned/
