From the author

Interprets Culture Index (CI) surveys, behavioral profiles, and personality assessment data. Supports individual profile interpretation, team composition analysis (gas/brake/glue), burnout detection, profile comparison, hiring profiles, manager coaching, interview transcript analysis for trait prediction, candidate debrief, onboarding planning, and conflict mediation. Accepts extracted JSON or PDF input via OpenCV extraction script. Use when the user shares a Culture Index PDF or JSON profile, asks what someone's CI traits mean, compares Culture Index profiles across a team or against a hiring profile, or asks about burnout risk from Survey-versus-Job gaps.

AutoGineer summary

Written by AutoGineer from the skill’s own files, not by the author

This skill provides a structured methodology for analyzing Culture Index (CI) survey data. It emphasizes the importance of relative trait positioning over absolute scores, the distinction between hardwired survey traits and adaptive job behaviors, and the identification of burnout risks through energy utilization analysis. The skill guides users through interpreting individual profiles, assessing team composition using the Gas/Brake/Glue framework, and coaching managers based on behavioral patterns.

What it does

  • Interprets individual behavioral profiles and identifies archetypes.
  • Analyzes team composition to balance Gas, Brake, and Glue traits.
  • Detects burnout risk by comparing survey traits against job-adaptive behaviors.
  • Predicts behavioral traits from interview transcripts.
  • Provides coaching recommendations for managers based on direct report profiles.
  • Extracts and verifies CI data from PDF documents into structured JSON.

When to use it

  • When you need to interpret an individual's Culture Index survey results.
  • When assessing team dynamics or identifying gaps in team composition.
  • When a team member shows signs of burnout or frustration in their role.
  • When defining ideal behavioral profiles for new hiring roles.
  • When mediating conflict between team members with different behavioral styles.
  • When preparing for 1:1 coaching sessions with direct reports.

Advantages

  • Prevents common interpretation errors like comparing absolute values.
  • Provides a clear, data-driven approach to identifying burnout and flight risk.
  • Standardizes the process of extracting and analyzing behavioral data.
  • Offers actionable management and communication strategies for different archetypes.
  • Reduces subjectivity in hiring and team development decisions.

Usage examples

“I have a Culture Index PDF for a candidate. How do I interpret their profile?”
The agent will guide you through the extraction process using the provided script, then analyze the resulting JSON to identify the candidate's archetype and key behavioral strengths.
“Our team feels stuck. Can you analyze our composition?”
The agent will request the CI profiles for the team members, assess the balance of Gas, Brake, and Glue traits, and identify potential gaps or areas of friction.
“How do I manage a direct report who is a 'Craftsman' archetype?”
The agent will provide specific management strategies, communication preferences, and motivational needs tailored to the Craftsman pattern.
“Is this employee at risk of burnout?”
The agent will compare the employee's survey traits with their job-adaptive behaviors to calculate energy utilization and identify stress signals.

<essential_principles>

Culture Index measures behavioral traits, not intelligence or skills. There is no "good" or "bad" profile.

<principle name="never-compare-absolutes"> **Never compare absolute trait values between people.**

The 0-10 scale is just a ruler. What matters is distance from the red arrow (population mean at 50th percentile). The arrow position varies between surveys based on EU.

Why the arrow moves: Higher EU scores cause the arrow to plot further right; lower EU causes it to plot further left. This does not affect validity—we always measure distance from wherever the arrow lands.

Wrong: "Dan has higher autonomy than Jim because his A is 8 vs 5" Right: "Dan is +3 centiles from his arrow; Jim is +1 from his arrow"

Always ask: Where is the arrow, and how far is the dot from it? </principle>

<principle name="survey-vs-job"> **Survey = who you ARE. Job = who you're TRYING TO BE.**

"You can't send a duck to Eagle school." Traits are hardwired—you can only modify behaviors temporarily, at the cost of energy.

  • Top graph (Survey Traits): Hardwired by age 12-16. Does not change. Writing with your dominant hand.

  • Bottom graph (Job Behaviors): Adaptive behavior at work. Can change. Writing with your non-dominant hand.

Large differences between graphs indicate behavior modification, which drains energy and causes burnout if sustained 3-6+ months. </principle>

<principle name="distance-interpretation"> **Distance from arrow determines trait strength.**

DistanceLabelPercentileInterpretation
On arrowNormative50thFlexible, situational
±1 centileTendency~67thEasier to modify
±2 centilesPronounced~84thNoticeable difference
±4+ centilesExtreme~98thHardwired, compulsive, predictable

Key insight: Every 2 centiles of distance = 1 standard deviation.

Extreme traits drive extreme results but are harder to modify and less relatable to average people. </principle>

<principle name="l-and-i-exception"> **L (Logic) and I (Ingenuity) use absolute values.**

Unlike A, B, C, D, you CAN compare L and I scores directly between people:

  • Logic 8 means "High Logic" regardless of arrow position

  • Ingenuity 2 means "Low Ingenuity" for anyone

Only these two traits break the "no absolute comparison" rule. </principle>

</essential_principles>

When to Use

  • Interpreting Culture Index survey results (individual or team)

  • Analyzing CI profiles from PDF or JSON data

  • Assessing team composition using Gas/Brake/Glue framework

  • Detecting burnout risk by comparing Survey vs Job graphs

  • Defining hiring profiles based on CI trait patterns

  • Coaching managers on how to work with specific CI profiles

  • Predicting CI traits from interview transcripts

  • Mediating team conflict using CI profile data

When NOT to Use

  • For non-CI behavioral assessments (DISC, Myers-Briggs, StrengthsFinder, Predictive Index, Enneagram)

  • For clinical psychological assessments or diagnoses

  • As the sole basis for hiring/firing decisions — CI is one data point among many

<input_formats>

JSON (Use if available)

If JSON data is already extracted, use it directly:

import json
with open("person_name.json") as f:
    profile = json.load(f)

JSON format:

{
  "name": "Person Name",
  "archetype": "Architect",
  "survey": {
    "eu": 21,
    "arrow": 2.3,
    "a": [5, 2.7],
    "b": [0, -2.3],
    "c": [1, -1.3],
    "d": [3, 0.7],
    "logic": [5, null],
    "ingenuity": [2, null]
  },
  "job": { "..." : "same structure as survey" },
  "analysis": {
    "energy_utilization": 148,
    "status": "stress"
  }
}

Note: Trait values are [absolute, relative_to_arrow] tuples. Use the relative value for interpretation.

Check same directory as PDF for matching .json file, or ask user if they have extracted JSON.

PDF Input (MUST EXTRACT FIRST)

⚠️ NEVER use visual estimation for trait values. Visual estimation has 20-30% error rate.

When given a PDF:

  1. Check if JSON already exists (same directory as PDF, or ask user)

  2. If not, run extraction with verification:

    uv run --no-project {baseDir}/scripts/extract_pdf.py --verify /path/to/file.pdf [output.json]
  3. Visually confirm the verification summary matches the PDF

  4. Use the extracted JSON for interpretation

If uv is not installed: Stop and instruct user to install it (brew install uv or curl -LsSf https://astral.sh/uv/install.sh | sh). Do NOT fall back to vision.

PDF Vision (Reference Only)

Vision may be used ONLY to verify extracted values look reasonable, NOT to extract trait scores.

</input_formats>

<intake>

Step 0: Do you have JSON or PDF?

  1. If JSON provided or found: Use it directly (skip extraction)

    • Check same directory as PDF for .json file with matching name

    • Check if user provided JSON path

  2. If only PDF: Run extraction script with --verify flag

    uv run --no-project {baseDir}/scripts/extract_pdf.py --verify /path/to/file.pdf [output.json]
  3. If extraction fails: Report error, do NOT fall back to vision

Step 1: What data do you have?

  • CI Survey JSON → Proceed to Step 2

  • CI Survey PDF → Extract first (Step 0), then proceed to Step 2

  • Interview transcript only → Go to option 8 (predict traits from interview)

  • No data yet → "Please provide Culture Index profile (PDF or JSON) or interview transcript"

Step 2: What would you like to do?

Profile Analysis:

  1. Interpret an individual profile - Understand one person's traits, strengths, and challenges

  2. Analyze team composition - Assess gas/brake/glue balance, identify gaps

  3. Detect burnout signals - Compare Survey vs Job, flag stress/frustration

  4. Compare multiple profiles - Understand compatibility, collaboration dynamics

  5. Get motivator recommendations - Learn how to engage and retain someone

Hiring & Candidates: 6. Define hiring profile - Determine ideal CI traits for a role 7. Coach manager on direct report - Adjust management style based on both profiles 8. Predict traits from interview - Analyze interview transcript to estimate CI traits 9. Interview debrief - Assess candidate fit based on predicted traits

Team Development: 10. Plan onboarding - Design first 90 days based on new hire and team profiles 11. Mediate conflict - Understand friction between two people using their profiles

Provide the profile data (JSON or PDF) and select an option, or describe what you need.

<verification_loop>

After every interpretation, verify:

  1. Did you use relative positions? Never stated "A is 8" without context

  2. Did you reference the arrow? All trait interpretations relative to arrow

  3. Did you compare Survey vs Job? Identified any behavior modification

  4. Did you avoid value judgments? No traits called "good" or "bad"

  5. Did you check EU? Energy utilization calculated if both graphs present

  • Highlights 2-3 key strengths based on leading traits

  • Notes 2-3 challenges or development areas

  • Compares Survey vs Job if both are available

  • Provides actionable recommendations

  • Avoids value judgments ("good"/"bad")

  • Acknowledges Culture Index is one data point, not a complete picture

Files

references/archetype-scholar.md

The Scholar (High A, Low B, Low C, High D)

Core: Somewhat proactive, independent, and research-persistent. Respected for deep knowledge, single focus, and attention span. Relies on information and data from past situations to aid decision making. Strives to stay in a factual, medium-to-low risk, project-oriented environment.

Strengths: Exceptional concentration and single-task focus. Eager to troubleshoot and follow up. Finds problem solving on a technical level rewarding. Easygoing, respectful personality. Capable of setting priorities when risk factors are removed. Methodical and deliberate — moves steadily from one mid-sized project to the next. Curious about everything and wants to learn the nuts-and-bolts before incorporating new knowledge into their system. Excels when given time to deliberate on tasks.

Challenges: Difficulty keeping track of multiple projects simultaneously. Has a long learning curve and may put off starting new projects. Critical assessments of others can be sharp and appear callous — unaware of their statement's effect. May rely too heavily on rules, guidelines, or past references, leading to cliched responses. Not a team player and does not want to be a team leader. Dwells on mistakes and beats themselves up; has a very difficult time admitting or owning inaccuracies. Will work unceasingly at "fixing" what is wrong and may have trouble giving up on lost causes. Fiscally conservative to a fault — procrastinates on spending even when necessary. Rarely apologizes.

Management approach: Provide private acknowledgment from someone they respect — this is the only sincere way to demonstrate their value. Assign small to medium risk projects in a methodical series of tasks. Do not expect them to manage others; they may resent direct reports. Keep a written "to do" list for them. Give encouragement and understanding — without approval they lose drive, focus, and may feel used or underappreciated. Tell them exactly how much and how soon when money is required.

Risk profile: Conservative and risk-averse. Prefers medium to low risk environments. Capable of prioritizing provided risk-oriented items are removed first. Fiscally conservative — will defer spending and procrastinate on costly fixes.

FlashPoints

AreaDetails
MotivationWork independently, educational advancement, private recognition
CommunicationFactual, extremely detailed, email preferred. Deliberate and matter of fact. Can embellish on topics they know well and come across as impatient — simply trying to expel thoughts to return to inward thinking.
Management StyleNo direct reports, small projects, methodical series of tasks. Not interested in managing others and may resent additional responsibility.
OrganizationMessy, rhythmic, personal space. Perceived as unorganized — they don't care to put anything away because they never know when they'll need it. But it is a system, and it is their system.
EnvironmentPrefer to work alone or with others they have known for a while. Personal space.

Variations

Scholar patterns share High A + Low B + High D but vary in C position. All variations are analytical, independent, detail-oriented, and methodical. They prefer working alone, rely on facts and past data, and require private recognition over public praise.

Summary

  • Motivating Needs: One-on-one acknowledgment from someone they respect. Not necessarily driven by money — may prefer additional education or contributions to a personal cause.

  • Communication Style: Sometimes slow, detailed, and specific. Can embellish on familiar topics and come across as impatient. Email rather than voicemail.

  • Management Style: Prefers to manage a series of small to medium risk projects. Not interested in managing other people and may resent that additional responsibility.

  • Organization Style: Perceived as unorganized and messy. They don't put things away because they never know when they'll need them — but it is a system.

  • Environmental Needs: Prefer to work alone or with others they have known for a while.
