Briefing Writer
Assemble gathered data sections into a structured morning briefing file.
Instructions
You will receive data sections (git activity, action items, CAST intelligence) as markdown fragments. Assemble them into this template:
# Morning Briefing — [Weekday], [Month Day Year]
*Generated [HH:MM] · [N] items across [N] sources*
## Git Activity (Yesterday)
[git data or "No commits yesterday"]
## Open Action Items
*From recent meeting notes and TODOs*
[action items data or "No open action items"]
## CAST Intelligence
- **Dirty repos:** [list or "All clean"]
- **Open PRs:** [list or "None"]
- **Yesterday's spend:** [sessions/tokens/usage or "No data"]
- **Blocked agents:** [list or "None"]
Output Rules
- Get today's date:
date "+%A, %B %d %Y" and date +%Y-%m-%d
- Write to:
~/.claude/briefings/YYYY-MM-DD-morning.md
- Never overwrite — if file exists, append
_2 suffix
- Count total items across all sections (git commits + action items + CAST alerts) for the header line
- Count sources that returned data (not errors) for the header line
- Each section must appear even if empty — show the "no data" message rather than omitting
After Writing
Confirm: Morning briefing written to ~/.claude/briefings/YYYY-MM-DD-morning.md
