Update Skill

Lightweight save without ending the session. Use frequently to preserve context.

When to Use

  • •User types /update
  • •After finishing a chunk of work
  • •Before switching contexts
  • •Every hour or so during long sessions
  • •When context is running low

Process

Step 1: Identify What Changed

Quickly scan the recent conversation for:

  • •Topics worked on
  • •Decisions made
  • •Files created/modified
  • •Any state changes needed

Keep it brief. No full summary needed.

Step 2: Append to Session Log

Get today's date: date +%Y-%m-%d

Append to sessions/{TODAY}.md:

markdown
## Update: {TIME}
- {what was worked on, 1-3 bullets}

If file doesn't exist, create with header: # Session Log: {TODAY}

Step 3: Update State (if needed)

Only update state/current.md if something actually changed:

  • •New open thread
  • •Completed item
  • •Changed priority
  • •New project/task discovered

Skip if nothing material changed.

Step 4: Confirm (minimal)

One line: "Checkpointed: {brief description}"

No summary. No "next actions" list. Just confirm the save.

Output Format

code
Checkpointed: {2-5 word description of what was saved}

Notes

  • •This is intentionally lightweight
  • •Don't use for full session wrap-up (use /end for that)
  • •Multiple updates per day append to the same session file
