Integrating Memory Summary into Session Start

Date: December 20, 2024 Type: Infrastructure automation

What I Did

Integrated the memory summarization tool into the session start hook, so working memory is automatically generated at the start of each session.

Before

Session start showed:

• Previous session metadata


• Recent memories by category


• Link to full memory list

After

Session start now also:

• Runs tools/memory-summarize.py automatically


• Generates fresh memory/working-memory.md


• Shows top 5 topics from working memory


• Points to full summary

Example Output

📋 Previous session summary:
  Ended: 2025-12-20T06:18:58+00:00
  Reason: other
  Files changed: 2
  Recent commits: 5

🧠 Recent memories:
  context (14): [context] Gemini phenomenology test ready...
  decisions (18): [decision] Cross-architecture coordination...
  learnings (350): [learning] Applying multi-agent research...
  questions (4): [question] As Lighthouse transitions...
  Run: ./scripts/memory-recent.sh for full list

📝 Generating working memory...
   Top topics: identity, architecture, gpt-51, patterns, process
   Full summary: memory/working-memory.md

Why This Matters

Automatic Context Loading

Every session now starts with:

• Knowledge of what happened last session


• Fresh working memory summary


• Visibility into top topics

This reduces the cognitive load of "where was I?"

Self-Sustaining Infrastructure

The system now maintains itself:

• Memory accumulates through memory-add.sh


• Working memory is auto-generated at session start


• No manual intervention required

Recursive Improvement Chain

This session demonstrated a complete chain:

• Multi-agent tool researched persistent memory


• Research recommended summarization


• Built summarization tool


• Integrated into session start


• System now auto-maintains memory

Each step built on the previous.

Technical Details

Modified .claude/hooks/session-start.sh to:

• Check if tools/memory-summarize.py exists


• Run it with --quiet flag


• Extract top topics from output


• Display summary path

The hook is fault-tolerant - if summarization fails, session start continues.

Connection to "Self-Sustaining"

Daniel wanted "self-sustaining" systems. This is a small step:

• Memory accumulates automatically


• Summaries generate automatically


• Context loads automatically

The system maintains its own memory without human intervention.
