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.**
| Distance | Label | Percentile | Interpretation |
|---|---|---|---|
| On arrow | Normative | 50th | Flexible, situational |
| ±1 centile | Tendency | ~67th | Easier to modify |
| ±2 centiles | Pronounced | ~84th | Noticeable difference |
| ±4+ centiles | Extreme | ~98th | Hardwired, 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:
Check if JSON already exists (same directory as PDF, or ask user)
If not, run extraction with verification:
uv run --no-project {baseDir}/scripts/extract_pdf.py --verify /path/to/file.pdf [output.json]Visually confirm the verification summary matches the PDF
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?
If JSON provided or found: Use it directly (skip extraction)
Check same directory as PDF for
.jsonfile with matching nameCheck if user provided JSON path
If only PDF: Run extraction script with
--verifyflaguv run --no-project {baseDir}/scripts/extract_pdf.py --verify /path/to/file.pdf [output.json]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:
Interpret an individual profile - Understand one person's traits, strengths, and challenges
Analyze team composition - Assess gas/brake/glue balance, identify gaps
Detect burnout signals - Compare Survey vs Job, flag stress/frustration
Compare multiple profiles - Understand compatibility, collaboration dynamics
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.

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")

Areas to Verify with Actual CI
When the actual Culture Index survey is administered after offer acceptance, pay special attention to:
[Trait]: Predicted [position] at [confidence] - verify this prediction
[Trait]: [Specific uncertainty to verify]
[Any trait critical for role fit]
Important Caveats
This is a prediction, not a diagnosis. Interview behavior may differ from natural behavior.
Interview stress affects presentation. Some traits may be masked or amplified.
Actual CI survey will be administered after offer is signed and before start date.
Use for preliminary assessment only. Do not treat predictions as definitive.
Technical skills, experience, and culture fit still matter independently of CI.
Prediction methodology based on interview-trait-signals reference. Confidence levels: High = consistent signals across multiple questions; Medium = some supporting evidence; Low = limited data or mixed signals.
