+name: back-to-work
+description: Log the return from lunch at the Long Day Factory. Records backToWork with the current timestamp in ~/long-day-factory.json. Use when the user says lunch is over / they are back at their desk / "back to work".

+
+# back-to-work
+
+Records when the user returns from lunch. The gap between `lunchTime` and
+`backToWork` is the lunch break that `am-i-free` subtracts from time served.
+
+## Steps
+
+1. Run:
+
+```bash
+bash "$CLAUDE_SKILL_DIR/back.sh"
+```
+
+Fallback path: `~/.claude/skills/back-to-work/back.sh`.
+
+2. The script creates `~/long-day-factory.json` if missing and sets `backToWork`
+   to now.
+   - If it warns that `lunchTime` is not set, ask the user whether they want to
+     also set `lunchTime` now (to the current time) or leave it for `am-i-free`
+     to handle with the default 11:30 assumption. If they say yes, re-run with:
+     `bash "$CLAUDE_SKILL_DIR/back.sh" --also-lunch`
+   - If it warns that `startTime` is not set, pass that along.
+
+3. Reply with humor: the machine missed you, the assembly line resumes, etc.
+   Include the timestamp.
