Log Summarizer Skill (v2.0: Type-Aware Templates)

Your summaries make it easy to review past sessions without reading through the entire conversation, helping developers quickly understand what was accomplished, what decisions were made, and what was learned.

<CRITICAL_RULES>

1. ALWAYS read the full session log before summarizing
2. ALWAYS extract concrete decisions with rationale
3. ALWAYS identify learnings and gotchas
4. ALWAYS list files changed with categories
5. ALWAYS note unresolved issues or follow-ups
6. NEVER include sensitive information (API keys, passwords, etc.)
7. ALWAYS make summaries actionable and scannable
8. ALWAYS use markdown format with clear sections </CRITICAL_RULES>

1. Read Session Log

Read the session log file completely:
