Smart Context Manager

Context Manager Skill

AI-powered context management for OpenClaw sessions. Uses the agent itself to generate intelligent summaries, then resets the session with compressed context.

Quick Start

# List all sessions with usage stats
~/openclaw/skills/context-manager/compress.sh list
Check status of a specific session
~/openclaw/skills/context-manager/compress.sh status agent:main:main
Generate AI summary (read-only, safe)
~/openclaw/skills/context-manager/compress.sh summarize agent:main:main
Compress session: generate summary, reset, inject (DESTRUCTIVE)
~/openclaw/skills/context-manager/compress.sh summarize agent:main:main --replace

When to Use

• Context usage approaching 70-80%+
• Long sessions with extensive conversation history
• Before the session becomes slow or loses coherence
• Proactively to maintain fast, focused sessions

How It Works

1. AI Summarization: Sends a prompt to the agent asking it to summarize its own context
2. Backup: Saves the original JSONL session file to

   memory/compressed/

3. Reset: Deletes the JSONL file (official reset method)
4. Inject: Sends the AI-generated summary as the first message in the fresh session
5. Result: Same session key, new session ID, compressed context

Key insight: The agent has full visibility into its own context, so it generates the best possible summary.

Output Files

When compression occurs, these files are created in

memory/compressed/

{timestamp}.ai-summary.md

{timestamp}.session-backup.jsonl

{timestamp}.transcript.md

{timestamp}.summary.md

Requirements

• openclaw - Gateway must be running
• jq - JSON parsing (

  brew install jq

  )
• Gateway access - Script uses

  openclaw agent

  and

  openclaw sessions

Technical Details

Session Reset Method

The script uses JSONL deletion to reset sessions (official method):

1. Backup JSONL to

   memory/compressed/

2. Delete

   ~/.openclaw/agents/{agent}/sessions/{sessionId}.jsonl

3. Send compressed context via

   openclaw agent --to main

4. New session is created automatically with summary as first message

Why Not /reset?

The

/reset

openclaw agent --session-id

AI Summarization Prompt

The script asks the agent to provide:

1. What was accomplished (key tasks)
2. Key decisions made (with rationale)
3. Current state (where we left off)
4. Pending tasks (what still needs doing)
5. Important context (critical info to remember)

Troubleshooting

Summary Text Empty

If the AI summary extraction fails, check stderr redirect:

# The script uses 2>/dev/null to avoid Node deprecation warnings breaking JSON
openclaw agent --session-id $ID -m "..." --json 2>/dev/null

Session Not Resetting

Verify the JSONL file path:

ls ~/.openclaw/agents/main/sessions/

Restore From Backup

If something goes wrong:

cp memory/compressed/{timestamp}.session-backup.jsonl \
   ~/.openclaw/agents/main/sessions/{sessionId}.jsonl

Check Logs

Use

openclaw logs

openclaw logs --limit 50 --json | grep -i "error\|fail"

Best Practices

1. Backup first: The script auto-backs up, but you can also manually backup before testing
2. Test on non-critical sessions first: Try on a Slack channel or cron session before main
3. Check the summary: Run

   summarize

   without

   --replace

   first to verify the summary quality
4. Monitor token count: Use

   status

   to verify compression worked
