Context Manager Skill

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

Quick Start

bash
# List all sessions with usage stats
~/clawd/skills/context-manager/compress.sh list

# Check status of a specific session
~/clawd/skills/context-manager/compress.sh status agent:main:main

# Generate AI summary (read-only, safe)
~/clawd/skills/context-manager/compress.sh summarize agent:main:main

# Compress session: generate summary, reset, inject (DESTRUCTIVE)
~/clawd/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 per Moltbot docs)
  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/:

FileDescription
{timestamp}.ai-summary.mdAI-generated session summary
{timestamp}.session-backup.jsonlFull backup of original session (can restore if needed)
{timestamp}.transcript.mdRaw transcript extraction (legacy)
{timestamp}.summary.mdGrep-based summary (legacy)

Requirements

  • •clawdbot/moltbot - Gateway must be running
  • •jq - JSON parsing (brew install jq)
  • •Gateway access - Script uses clawdbot agent and clawdbot sessions

Technical Details

Session Reset Method

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

  1. •Backup JSONL to memory/compressed/
  2. •Delete ~/.clawdbot/agents/{agent}/sessions/{sessionId}.jsonl
  3. •Send compressed context via clawdbot agent --to main
  4. •New session is created automatically with summary as first message

Why Not /reset?

The /reset slash command only works in the chat interface. When sent via clawdbot agent --session-id, it's treated as a regular message and the agent tries to interpret it as a task.

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:

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

Session Not Resetting

Verify the JSONL file path:

bash
ls ~/.clawdbot/agents/main/sessions/

Restore From Backup

If something goes wrong:

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

Check Logs

Use clawdbot logs to troubleshoot:

bash
clawdbot 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
