Pre-Compact Resume Card

Claude forgets when context compacts. This skill installs a PreCompact hook that captures real operational state before compaction fires — branch, commit, last user intent, last assistant action, detected mode, and next step. The next session loads it automatically via SessionStart.

What It Does

Before every context compaction, the hook:

1. Backs up the transcript to thinking/session-logs/ (keeps last 30)
2. Parses the JSONL transcript to extract the last user intent and assistant action
3. Detects the current work mode (coding / debugging / deploy / ideation / git workflow)
4. Writes .claude/session-resume-card.md with all of this

At session start, the card is injected into context automatically — no manual copy-paste needed.

Install

npx clawhub@latest install @openclaw/pre-compact-resume-card

Or manually: copy scripts/pre-compact.sh and scripts/session-start.sh into your project's .claude/scripts/, then register the hooks in .claude/settings.json using references/settings-example.json as template.

Hook Registration

{
  "hooks": {
    "PreCompact": [{ "matcher": "", "hooks": [{ "type": "command", "command": "bash .claude/scripts/pre-compact.sh" }] }],
    "SessionStart": [{ "matcher": "", "hooks": [{ "type": "command", "command": "bash .claude/scripts/session-start.sh" }] }]
  }
}

The Insight

Written rules get forgotten. Mechanical hooks don't. This skill is the difference between Claude starting fresh (useless) and Claude starting exactly where you left off (valuable). The resume card costs ~200 tokens per session start — cheap insurance against rebuilding context from scratch.
