COG Weekly Check-in Skill

Purpose

Comprehensive weekly review and analysis integrating insights across all domains (personal, professional, projects) with pattern recognition and strategic planning.

When to Invoke

User wants to do their weekly review
User says "weekly checkin", "weekly review", "reflect on my week"
End of week reflection time
User wants to analyze patterns across the week

Agent Mode Awareness

Check agent_mode in 00-inbox/MY-PROFILE.md frontmatter:

If agent_mode: team — delegate domain-specific analysis to sub-agents (e.g., one for personal patterns, one for professional review, one per active project). Each agent scans relevant braindumps/briefs and returns insights. Combine into the weekly synthesis.
If agent_mode: solo (default) — handle all scanning and analysis directly in the conversation. No delegation.

Pre-Flight Check

Check for user profile (optional but enhances experience):

Look for 00-inbox/MY-PROFILE.md in the vault
If found:
- Read user's name for personalization
- Read active projects to review project-specific progress
- Tailor reflection questions to user's role and projects

Get current timestamp (REQUIRED before generating any files):

Run date '+%Y-%m-%d %H:%M' using Bash to get the actual current date and time
Store this value and use it for the created: frontmatter field
NEVER guess or fabricate the time — always use the value returned by the date command

Process Flow

1. Gather Context

Scan recent files from the past week:

Daily briefs in 01-daily/briefs/
Braindumps in 02-personal/braindumps/, 03-professional/braindumps/, 04-projects/*/braindumps/
