compact-prep

## When to Use Casey says something like: - "thread is about to be compacted" - "save your context before compaction" - "output anything you need to carry over" - "what do you want to preserve" - "context is about to compress" ## What to Output A structured block under a `## Compaction Snapshot` header with these sections. Only include sections that have content — skip empty ones. ### 1. Current task state What you're in the middle of, what's done, what's next. Include file paths and line numbers for anything in-progress. ### 2. Working tree state Per-project `git status` and branch for any repo you've touched this session. Note uncommitted work, staged files, dirty trees. ### 3. Decisions made Choices that were discussed and resolved — the kind of thing that would waste time re-deriving. Include the reasoning if it's non-obvious. ### 4. Key findings Facts you discovered during the session that aren't written down elsewhere (not in a file, not in a commit message, not in a skill). If it's already persisted on disk, skip it. ### 5. Blocked / waiting on Anything paused pending external input, a running background process, or a dependency. ### 6. File locations touched List of files created or modified this session, grouped by project. This helps post-compaction orientation — "what did I change?" is the first question. ### 7. Open threads Conversations or sub-topics that were started but not finished. Include enough context to resume without re-reading the full pre-compaction thread. ## Rules - **Be specific, not narrative.** Paths, versions, line numbers, command outputs — not summaries of summaries. - **Assume the post-compaction context has only the snapshot + CLAUDE.md.** Everything else may be lost or compressed to a sentence. - **Don't pad.** If the session was simple and everything is persisted on disk, a 3-line snapshot is fine. - **Don't ask what to include.** Output everything that matters — Casey triggered this because compaction is imminent, not to start a conversation about what's important.
