SKILL.md72 linessingle file

Identity Snapshot

Reads existing Dex data and synthesizes System/identity-model.md — a living document the system writes, not the user. This captures who you are as a professional based on your actual behavior, not self-reported traits.

When to Run

Manually via /identity-snapshot
Auto-triggered during /week-review (append identity model update to review workflow)

Data Sources

Read ALL of the following in parallel before synthesizing:

Quarter Goals — 01-Quarter_Goals/Quarter_Goals.md
- What you're working toward, pillar distribution, ambition level
Week Priorities — 02-Week_Priorities/Week_Priorities.md
- Recent 4 weeks of priorities (look for patterns in what gets prioritized)
Tasks — 03-Tasks/Tasks.md
- Completion patterns, pillar distribution, velocity, what gets blocked
Session Learnings — System/Session_Learnings/*.md (last 30 days)
- What you've learned, recurring themes
Mistake Patterns — 06-Resources/Learnings/Mistake_Patterns.md
- Known failure modes, triggers, what to watch for
Skill Ratings — System/Skill_Ratings/ratings.jsonl
- Which skills score highest, what you value in AI interactions
User Profile — System/user-profile.yaml
- Existing identity data, communication preferences

Synthesis

Write to System/identity-model.md with this structure:

# Identity Model
*Auto-generated by Dex — last updated YYYY-MM-DD*

## Working Patterns
- Pillar balance: [distribution across pillars]
