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

<success_criteria>

A well-interpreted Culture Index profile:

  • Uses relative positions (distance from arrow), never absolute values alone

  • Identifies the archetype/pattern correctly

  • 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

<overview>

Common mistakes when interpreting Culture Index profiles. Avoiding these errors is as important as understanding the methodology itself.

</overview>

<interpretation_mistakes>

<mistake name="comparing-absolutes">

Comparing absolute trait values between people

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"

Why it's wrong: The arrow position varies between surveys based on EU. An 8 with an arrow at 6 is only +2 from norm. A 5 with an arrow at 2 is +3 from norm.

Only exception: L and I use absolute values and CAN be compared directly.

</mistake>

<mistake name="ignoring-arrow">

Ignoring the red arrow position

The arrow is the population mean (50th percentile). All interpretation must be relative to it.

Wrong: "This person has low B (score of 3)"

Right: "This person's B is 2 centiles left of their arrow, indicating pronounced introversion"

</mistake>

<mistake name="value-judgments">

Treating traits as "good" or "bad"

Culture Index measures behavioral traits, not value or capability.

Wrong:

  • "High D is good because they're detail-oriented"

  • "Low B is bad because they're not social"

Right:

  • "High D indicates strong attention to detail - fits roles requiring precision"

  • "Low B indicates preference for focused work - fits analytical roles"

There is no universally "good" profile. Fit depends on role, team, and context.

</mistake>

<mistake name="stale-data">

Using outdated data (18+ months old)

Job behaviors update as environment, leadership, or projects change. Stale data leads to wrong conclusions.

Best practice: Resurvey job behaviors every 6 months, especially after major role or leadership changes.

</mistake>

<mistake name="single-trait-focus">

Over-indexing on a single trait

The pattern (relationship between traits) matters more than any individual dot.

Wrong: "They have High A, so they're a leader"

Right: "High A combined with High D suggests they can build new systems. High A with Low D suggests they'll drive fast but may miss details."

</mistake>

<mistake name="ignoring-survey-vs-job">

Not comparing Survey vs Job graphs

Missing burnout signals by only looking at one graph.

Always check:

  • Did the arrow move? (Stress/Frustration signal)

  • Did any dots flip sides? (Polarizing shift - flight risk)

  • What's the EU utilization? (>130% stress, <70% frustration)

</mistake>

<mistake name="confusing-traits-behaviors">

Confusing traits with behaviors

Survey (top) = hardwired traits (who you ARE) Job (bottom) = adaptive behaviors (who you're TRYING TO BE)

Traits don't change. Behaviors can be modified temporarily - but at an energy cost.

"You can't send a duck to Eagle school." - You can train behaviors, not traits.

</mistake>

</interpretation_mistakes>

<application_mistakes>

<mistake name="seeking-homogeneity">

Hiring for homogeneous teams

Hiring people who match the manager's profile creates blind spots.

Better approach: Build diverse teams with complementary traits. Every team needs Gas (High A), Brake (High D), and Glue (High B) in appropriate proportions.

</mistake>

<mistake name="overloading-high-a">

Overloading on High A's

High A's are "the single hardest trait to employ." They work for "me, Inc." first.

Too many High A's = power struggles, lack of follow-through, no one to execute.

You are only RENTING High A's - they need a mutually beneficial partnership.

</mistake>

<mistake name="neglecting-brake">

Neglecting the Brake (High D)

Every team needs quality control, risk management, and follow-through.

Without Brake: Erosion, mistakes, lawsuits, quality issues, things start but never finish.

</mistake>

<mistake name="assuming-fit-permanent">

Assuming job fit is permanent

People's roles evolve. Business needs change. What fit yesterday may not fit tomorrow.

Regular check-ins (resurvey every 6 months) catch misalignment before it becomes burnout or turnover.

</mistake>

<mistake name="using-ci-alone">

Using Culture Index as the only data point

Culture Index is ONE tool among many. It measures behavioral traits, not:

  • Skills or competencies

  • Intelligence

  • Experience

  • Values

  • Motivation

Best practice: Use CI alongside interviews, references, skills assessments, and performance data.

</mistake>

</application_mistakes>

<communication_mistakes>

<mistake name="sharing-raw-scores">

Sharing raw scores without context

Telling someone "Your A is 8" without explaining relative position is meaningless and potentially harmful.

Always communicate:

  • Position relative to arrow

  • What that means behaviorally

  • Why it's neither good nor bad

  • How it fits (or doesn't) with their role

</mistake>

<mistake name="labeling-people">

Using CI to label or box people

CI shows tendencies, not destiny.

Wrong: "You're a Persuader, so you should only do sales"

Right: "Your pattern shows strengths in influence and relationship building. How do you use those in your current role?"

</mistake>

<mistake name="public-comparison">

Comparing profiles publicly

Never compare individuals' profiles in group settings without their consent.

Discussing "Person A is more detail-oriented than Person B" creates hierarchy and judgment.

</mistake>

</communication_mistakes>

<red_flags>

Signals that suggest deeper investigation:

SignalWhat to Check
EU 0-10 (avoidant response)Was survey completed properly? Trust issues?
All dots on or near arrowChameleon pattern - less than 0.57% of population. Verify validity.
Job behaviors completely opposite of SurveyImminent flight risk. What's causing this extreme modification?
EU utilization > 150%Severe stress. Immediate conversation needed.
EU utilization < 50%Severe disengagement. May have already mentally quit.
D raised significantly in Job behaviorsMost common unsustainable stress pattern. Why do they feel they need to be so much more perfectionist?

</red_flags>

<checklist>

Before finalizing any interpretation:

  • [ ] Did I use relative positions (distance from arrow)?

  • [ ] Did I avoid calling any trait "good" or "bad"?

  • [ ] Did I compare Survey vs Job if both available?

  • [ ] Did I calculate EU utilization?

  • [ ] Did I consider the full pattern, not just leading traits?

  • [ ] Is my data current (less than 18 months old)?

  • [ ] Did I note that CI is one data point among many?

</checklist>

<rationalization_table>

Common excuses that indicate you're about to make a CI interpretation mistake:

ExcuseReality
"Their A is higher so they're more autonomous"Compare distance from arrow, not absolute values
"This is a bad profile for leadership"No bad profiles - fit depends on role and context
"They need to change their C trait"Survey traits are hardwired - change the environment instead
"Low B means they're not a team player"Low B means they prefer focused work - they can still collaborate
"High D is always good for quality"High D without other traits can mean paralysis and rigidity
"They should be more like their manager"Different profiles bring complementary strengths
"This pattern can't do that job"Patterns indicate tendencies, not hard limits
"Their EU is fine, the job is the problem"EU tells you about energy, not about job design
"I remember their profile from last year"Resurvey Job behaviors every 6 months - they change
"The arrow doesn't matter, just look at the dots"The arrow IS the reference point - dots mean nothing without it
"L and I work the same as A, B, C, D"L and I use absolute values, primary traits are relative
"Survey and Job will be the same"Survey = hardwired, Job = adaptive. They often differ.
"High A means they're selfish"High A means they're self-directed - not the same thing
"We need all High A's on this high-growth team"You're renting High A's, and they'll clash with each other
"This hire looks good, skip the CI"CI is one data point - use it WITH other assessments, not instead of
