Summarizing Session End

Session End Summary

Generates a structured session summary when triggered by the SessionEnd hook. Reuses the compacting-context template to produce consistent, synthesis-ready notes.

Hook Configuration

Add to .claude/settings.json:

{
  "hooks": {
    "SessionEnd": [
      {
        "type": "prompt",
        "prompt": "/summarizing-session-end"
      }
    ]
  }
}

Workflow

1. Gather context -- Review the conversation for what was accomplished,

which files were touched, and any unresolved issues.

1. Generate session ID -- Use the current date and a short identifier

(first 8 chars of session UUID if available, or timestamp).

1. Write summary -- Create ~/.claude/session-summaries/YYYY-MM-DD-.md

using the output template below. Create the directory if it does not exist.

1. Keep it brief -- The summary must be under 50 lines. This is a summary,

not a transcript.

Output Template

Write to ~/.claude/session-summaries/YYYY-MM-DD-.md:

# Session Summary -- YYYY-MM-DD

## Trajectory

## Key Files

## Completed

## Blockers

## Findings

Quality Check

• Correct > Complete > Minimal (ACE-FCA)
• Under 50 lines output
• No raw logs or tool dumps
• Enough for bigpicture synthesis to consume
