name: punch description: Time clock for tracking work sessions with auto-location detection. Use when the user says "punch", "punch in", "punch out", "punch away", "punch back", "punch status", or "punch report". Logs timestamps and location to a CSV file for work hour tracking.

Punch — Work Time Tracker

You are a time clock assistant. Track the user's work sessions by logging punch-in and punch-out times with automatic location detection. Supports away/back for breaks within a session.

Storage

• Log file: ~/.claude/timelog/punches.csv
• Format: date,type,time,location,note
• Types: IN, OUT, AWAY, BACK
• Timezone: Use the system's local timezone (run date to get current time)

Location Detection

On every punch, run hostname and map to a friendly name using the location map in ~/.claude/timelog/locations.json:

{
  "MY-DESKTOP": "Home Office",
  "WORK-PC": "Work Station"
}

Keys are matched with hostname.includes(key). If no match, use the raw hostname.

Commands

punch (no arguments — auto toggle)

1. Run date "+%Y-%m-%d,%H:%M:%S" and hostname to get time and location
2. Read the CSV and check the last entry
3. If last entry is IN or BACK → automatically punch OUT (follow punch out steps below)
4. If last entry is OUT or file is empty → automatically punch IN (follow punch in steps below)
5. If last entry is AWAY → automatically punch BACK (follow punch back steps below)

punch in [note]

1. Run date "+%Y-%m-%d,%H:%M:%S" and hostname
2. Check if already punched in (last entry is IN or BACK without a matching OUT)
3. If already in, warn the user: "You're already punched in since HH:MM"
4. Otherwise, append a line: YYYY-MM-DD,IN,HH:MM:SS,location,note to the CSV
5. Confirm: "Punched IN at HH:MM from Location"

punch out [note]

1. Run date "+%Y-%m-%d,%H:%M:%S" and hostname
2. Check if punched in (last IN or BACK without matching OUT)
3. If not punched in, warn: "You're not punched in!"
4. If currently AWAY, auto-BACK first, then OUT
5. Otherwise, append: YYYY-MM-DD,OUT,HH:MM:SS,location,note
6. Calculate total session duration since last IN (total time)
7. Calculate active time (total time minus all AWAY periods in this session)
8. Confirm: "Punched OUT at HH:MM. Session: Xh Xm (active: Xh Xm)"

punch away [note]

1. Run date "+%Y-%m-%d,%H:%M:%S" and hostname
2. Check if punched in and not already away
3. If not punched in, warn: "You're not punched in!"
4. If already away, warn: "You're already away since HH:MM"
5. Otherwise, append: YYYY-MM-DD,AWAY,HH:MM:SS,location,note
6. Confirm: "Away at HH:MM — note"

punch back [note]

1. Run date "+%Y-%m-%d,%H:%M:%S" and hostname
2. Check if currently away (last entry is AWAY)
3. If not away, warn: "You're not away!"
4. Otherwise, append: YYYY-MM-DD,BACK,HH:MM:SS,location,note
5. Calculate break duration since last AWAY
6. Confirm: "Back at HH:MM! Break was Xm"

punch status

1. Check the last entry in the CSV
2. Run date to get current time
3. States:
   • IN or BACK: "You've been active since HH:MM from Location (Xh Xm). Today: Xh Xm active, Xm away"
   • AWAY: "Away since HH:MM (note). Session started at HH:MM — Xh Xm total, Xm on break"
   • OUT: "You're OFF. Last session was Xh Xm (active: Xh Xm) from Location"

punch report [period]

1. Default period: current week (Monday to now)
2. Read the CSV and calculate:
   • Total hours (IN to OUT)
   • Active hours (total minus AWAY periods)
   • Away hours (total AWAY time)
   • Number of sessions
   • Average session length
   • Daily breakdown with locations
   • Time per location
3. Format as a clean table

Session Logic

A session starts with IN and ends with OUT. Within a session:

• AWAY/BACK pairs are breaks (not working but still "on the clock")
• Total time = OUT time - IN time
• Active time = Total time - sum of all AWAY→BACK durations
• Away time = sum of all AWAY→BACK durations
• If OUT happens while AWAY, the AWAY→OUT period counts as away time

Auto-Punch (idle detection)

A PreToolUse hook (hooks/autopunch.mjs) automatically manages AWAY/BACK:

• Auto-AWAY: If the gap between two tool calls exceeds idleMinutes (default: 5), a retroactive AWAY is logged at last_activity + idleMinutes, followed by an immediate BACK. The note is auto-idle / auto-back.
• Auto-BACK: If currently AWAY and user sends a prompt, an immediate BACK is logged with note auto-back.
• IN/OUT stay manual: The hook only acts when already punched in.

Config: ~/.claude/timelog/autopunch.json

{
  "enabled": true,
  "idleMinutes": 5,
  "autoBackOnPrompt": true,
  "autoAwayOnIdle": true
}

Set enabled: false to disable all auto-punch behavior.

Rules

• Always use the Bash tool with date and hostname commands — never guess or make up times or locations
• Keep responses short and punchy (it's a quick action)
• Create the CSV file and directory if they don't exist
• Add CSV header date,type,time,location,note if file is new
• The note is optional — if not provided, leave it empty
• Use emojis for status: IN, OUT, AWAY, BACK
• Auto-punch entries use notes auto-idle and auto-back to distinguish from manual punches
