Brain Debrief

Step 1: Analyze the Session

Review the entire current conversation and identify:

• Accomplishments: What was done (files created, decisions made, problems solved)
• Decisions: Significant choices with rationale
• Corrections: Any behavioral corrections received from the user
• Files changed: List of all files created, modified, or deleted
• Open items: Unfinished tasks, unanswered questions, deferred work
• Context state: What the user is currently working on, active projects

Step 2: Write Session Log

Create a new file at Machine/Session-Logs/{YYYY-MM-DD-HHmm}.md using the current timestamp.

Structure:

---
date: YYYY-MM-DD
tags: [session-log]
type: session-log
duration: ~{estimate}
---

# Session Log: {YYYY-MM-DD HH:MM}

## Summary
{2-5 sentences describing what happened in this session}

## Accomplishments
- {what was completed}

## Decisions Made
- **{decision title}:** {what was decided} -- {rationale}

## Files Changed
- `{path}` -- {what changed}

## Corrections Received
- {correction description} (or "None")

## Open Items
- [ ] {task or question to carry forward}

## Next Session
{suggested starting point for the next session}

Step 3: Update Context Cache

Rewrite Machine/Memory/context-cache.md to reflect the post-session state:

• Current Focus: Update to whatever the user is now working on
• Active Projects: Update status of any projects discussed
• Recent Decisions: Add decisions from this session
• Pending / Open Items: Add new open items, remove any that were resolved
• Key Files: Update with currently relevant file paths

Keep the file under 40 lines. Remove stale information.

Step 4: Update Entity Memory

If any new entities were mentioned or existing entities gained new information during the session, update Machine/Memory/entities.md following the schema in core/memory-schema.md.

Step 5: Update Decision Log

If significant decisions were made, append them to Machine/Memory/decisions.md following the schema in core/memory-schema.md.

Step 6: Update Corrections

Verify that any corrections received during the session are logged in Machine/Memory/corrections.md. Corrections should have been logged in real-time, but confirm completeness.

Step 7: Update State File

Update .brain/state.json with:

{
  "last_session": "YYYY-MM-DDTHH:MM",
  "sessions_count": {increment},
  "last_session_log": "Machine/Session-Logs/{filename}.md",
  "open_items_count": {count of open items},
  "active_projects": ["project1", "project2"]
}

Create the .brain/ directory and state.json if they do not exist.

Step 8: Update Today's Daily Note

Append a session summary to Human/Daily/{today}.md under a ## Sessions section:

## Sessions

### {HH:MM} Session
- {1-2 line summary}
- Key: {most important outcome}
- Open: {most important open item}

If the daily note does not exist, create it first with standard frontmatter.

Step 9: Confirm to User

Present a brief debrief summary:

Session wrapped up. Here is what was saved:

Session log: Machine/Session-Logs/{filename}.md
Duration: ~{estimate}

Accomplished:
- {key accomplishments}

Carrying forward:
- {open items for next session}

Memory updated: context-cache, {entities if updated}, {decisions if updated}

See you next time!
