Log: Work Log Entry

Append a timestamped entry to the project's work log. When the active log exceeds 1000 lines, rotate it.

Directory

All logs live in worklog/ at the repo root.

• Active log: worklog/WORK_LOG.md
• Rotated logs: worklog/WORK_LOG-{YYYY-MM-DD-HHMMSS}.md

Process

1. Check if worklog/WORK_LOG.md exists. If not, create it with a # Work Log header.
2. Count lines in the active log.
3. If the line count exceeds 1000:
   • Rename the current file to worklog/WORK_LOG-{timestamp}.md using the current datetime.
   • Create a fresh worklog/WORK_LOG.md with the # Work Log header.
4. Determine entry content:
   • If the user provides an argument, use it as the entry content.
   • If the user provides no argument, summarize the most recent work from the conversation: what was done, what was decided, what's next. Write it in the same voice as the conversation — concise, specific, no filler. Include file paths, commit messages, or prediction records if relevant.
5. Append the entry to worklog/WORK_LOG.md with this format:

### {HH:MM} — {short summary of the action}

{entry content}

If the last ## {date} header in the file matches today's date, append under it. Otherwise, add a new ## {YYYY-MM-DD} header before the entry.

6. Report: line count after append, and whether rotation occurred.

Session-persistent logging

Running this skill once activates logging for the rest of the session. After the initial entry:

• Auto-log at natural milestones: commits, deploys, significant decisions, task completions, direction changes. Don't wait for the user to invoke /log again.
• Don't interrupt flow: append the log entry silently (no "I've logged this" announcements). Just do it alongside whatever else you're doing.
• Cadence: log when something worth recording happens, not on a timer. A session with three commits gets three entries. A session that's all discussion might get one entry at the end.
• Same format: every auto-logged entry follows the same ### HH:MM — summary format.

Rules

• Entries are append-only. Never edit or remove previous entries.
• If the user provides an argument, log it as given — don't paraphrase.
• If the user provides no argument, auto-summarize from conversation context. Be specific: names, tickers, predictions, decisions, not vague summaries.
• Keep the ## date / ### time — summary hierarchy consistent.
