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#

bash

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#

json

{
  "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.
