Save a summary of this conversation to the vault.

The vault is mounted at /workspace/vault/. If it doesn't exist, check /workspace/extra/obsidian/Deus/ as a legacy fallback.

Steps

  1. Resolve vault path:

    VAULT_DIR="${DEUS_VAULT_DIR:-/workspace/vault}"
    [ ! -d "$VAULT_DIR" ] && VAULT_DIR="/workspace/extra/obsidian/Deus"
    
  2. Reflect on the conversation — identify what's worth saving:

    • Decisions made, key learnings, files modified, pending tasks, errors/workarounds
  3. Determine a short topic slug from the main theme (e.g. google-calendar-setup, ui-debugging).

  4. Write the session log:

    $VAULT_DIR/Session-Logs/YYYY-MM-DD-{topic}.md
    

    Use this format — the tldr frontmatter field is mandatory; full sections are optional:

    ---
    type: session
    date: YYYY-MM-DD
    topics: [topic1, topic2]
    tldr: |
      What happened (1 sentence). Key decision or outcome. Pending: X, Y.
    ---
    
    <!-- Full details — only loaded on demand -->
    
    ## Decisions Made
    - ...
    
    ## Key Learnings
    - ...
    
    ## Files Modified
    - ...
    
    ## Pending Tasks
    - [ ] ...
    
    ## Errors & Workarounds
    - ...
    

    Keep tldr to 2–3 lines max — this is what gets loaded every session. Skip any full section that has no content.

  5. Update pending tasks in the vault if there are carry-forward items:

    • Update the pending: block in $VAULT_DIR/CLAUDE.md
    • Write it back
  6. Confirm: "Session saved to {filename}. {N} pending tasks carried forward."
