/timesheet
Update the project timesheet at .campaign/timesheet.md.
Instructions
- Read the current timesheet from
.campaign/timesheet.md - Use
AskUserQuestionto collect the following for each entry:- Description: What work was done
- Start time: When work started (e.g. "9:00 AM", "14:30")
- End time: When work ended (e.g. "11:30 AM", "17:00")
- Calculate the hours as the difference between end time and start time, rounded to 2 decimal places
- Append the new row to the markdown table in
.campaign/timesheet.md - Display the updated timesheet to the user
Weekly Summary Maintenance
Every time an entry is added, edited, or removed, recalculate the Weekly Summary table. Weeks are identified by their Monday start date (ISO week, Mon–Sun). The total hours line below the weekly summary must always equal the sum of all entry hours.
Calculating the week-starting Monday for a date:
- Monday → the date itself
- Tuesday → date − 1 day
- Wednesday → date − 2 days
- Thursday → date − 3 days
- Friday → date − 4 days
- Saturday → date − 5 days
- Sunday → date − 6 days
For example, Sunday 2026-03-01 belongs to the week starting Monday 2026-02-23 (subtract 6 days). Monday 2026-03-02 starts a new week. Always use this calculation — do NOT treat the entry date itself as the week start.
Timesheet Template
If .campaign/timesheet.md does not exist, create it with this content:
# Timesheet
## How to update
Run `/timesheet` in Claude Code to add entries, or use clock in/out:
- `/timesheet clock in` — starts a new entry at the current time
- `/timesheet clock out` — ends the open entry and prompts for a description
- `/timesheet` — manually add an entry (date, description, start/end times)
