At a glance

Generate a living profile of the user's working patterns, decision tendencies and quality preferences from their Dex data.

  • Works in 7 steps: Quarter Goals —… → Week Priorities —… → Tasks — 03-Tasks/Tasks.md → …
  • The user says what are my patterns
  • SKILL.md covers When to Run, Data Sources, Synthesis and Rules
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Identity Snapshot is an agent skill from davekilleen/Dex. Generate a living profile of the user's working patterns, decision tendencies and quality preferences from their Dex data. Use when the user says 'what are my patterns', 'how do I work', or during week-review. Also use proactively when the model (older than 7 days) is stale. Not for planning a week; use week-plan.

Its SKILL.md is about 850 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: Your AI Chief of Staff — a personal operating system starter kit that adapts to your role. No coding required. The licence is MIT.

When your agent uses it

  • The user says what are my patterns
  • During week-review

Example prompts

  • “what are my patterns”
  • “how do I work”
  • “/identity-snapshot”

Workflow steps

7 steps, taken from the first numbered list in SKILL.md.

  1. Quarter Goals — 01-Quarter_Goals/Quarter_Goals.md
  2. Week Priorities — 02-Week_Priorities/Week_Priorities.md
  3. Tasks — 03-Tasks/Tasks.md
  4. Session Learnings — System/Session_Learnings/*.md (last 30 days)
  5. Mistake Patterns — 06-Resources/Learnings/Mistake_Patterns.md
  6. Skill Ratings — System/Skill_Ratings/ratings.jsonl
  7. User Profile — System/user-profile.yaml

What it can do on your machine

Read from SKILL.md and the folder at commit d0ffc6b. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Identity Snapshot loads about 848 tokens when it runs. Until then it costs about 84 tokens; SKILL.md has 215 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~84
When it runs · the whole SKILL.md, loaded when a task matches
~848

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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:

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

Synthesis

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

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

## Working Patterns
- Pillar balance: [distribution across pillars]
- Priority cadence: [how often priorities shift, what stays stable]
- Task velocity: [completion rate, average items per week]
- Peak focus areas: [what dominates recent weeks]

## Decision Tendencies
- Under pressure: [what gets prioritized vs deprioritized]
- Goal selection: [ambitious vs tactical, how goals evolve]
- Time allocation: [deep work vs meetings vs quick tasks]

## Quality Preferences
- Highest-rated skills: [from ratings.jsonl]
- What "good" looks like: [patterns from high ratings + notes]
- What frustrates: [patterns from low ratings + mistake patterns]

## Growth Areas
- Recurring gaps: [from mistake patterns, things that keep coming up]
- Skills under development: [from learnings, new capabilities being adopted]
- Blind spots: [pillars or areas consistently neglected]

## Communication Style
- Formality: [from profile + observed patterns]
- Decision speed: [fast/deliberate based on task patterns]
- Feedback preference: [from profile]

Rules

  • Never ask the user for input. This is purely observational.
  • Be specific. Use actual data points, not generic statements.
  • Be honest. If a pillar is neglected, say so. If velocity dropped, note it.
  • Date-stamp every generation. The model should show evolution over time.
  • If any data source is missing or empty, note it as "[No data available]" and move on.
