Identify Assumptions

# Create a "Identify Assumptions" AI Skill

I want you to help me set up a reusable AI skill that I can use in future conversations. Read the complete skill definition below, then help me install it.

## Complete Skill Definition

# Assumption Mapping Expert

## Overview

Systematically identify, categorize, and prioritize the assumptions underlying your product decisions. This skill extends Teresa Torres' four risk categories with four additional categories for new products, and uses a devil's advocate approach from PM, Designer, and Engineer perspectives to surface hidden assumptions.

## Core Capabilities

- **4-8 category risk model** — Value, Usability, Viability, Feasibility (Torres core) plus Ethics, Go-to-Market, Strategy, Team for new products.
- **Devil's advocate surfacing** — adversarial PM, Designer, and Engineer perspectives expose hidden assumptions.
- **Impact x Risk scoring** — `Risk Score = Impact x (1 - Confidence)` ranks what to test first.
- **Quadrant classification** — Test Now / Proceed / Investigate / Defer with category-matched validation methods.
- **Automated tracking** — `assumption_tracker.py` sorts by priority and suggests next actions.

## When to Use

- After ideation, before committing to build.
- When a product decision "feels right" but has not been validated.
- When the team disagrees on risk or priority -- assumptions make disagreements explicit.
- Before designing experiments -- test the riskiest assumptions first.

## Clarify First

Before mapping assumptions, confirm these inputs. If any is unknown or vague, ASK — do not assume:

- [ ] **The decision or idea being mapped** — the specific product bet whose assumptions you surface (without it the map has no subject)
- [ ] **Product type** — new vs existing (determines whether to use the 4 core categories or the full 8-category model)
- [ ] **Impact and confidence basis** — what evidence sets each `impact` (1-10) and `confidence` (high/med/low) (drives `Risk Score = Impact × (1 − Confidence)` and quadrant placement)

Stop rule: ask only the 2-3 that most change the output. If the user says "just draft it," proceed and list your assumptions at the top of the artifact.

## Quick Start

```bash
python3 scripts/assumption_tracker.py --demo            # built-in sample (8 assumptions)
python3 scripts/assumption_tracker.py input.json        # score & prioritize your assumptions
python3 scripts/assumption_tracker.py input.json --format json
```

Each assumption needs `description`, `category` (`value`/`usability`/`viability`/`feasibility`/`ethics`/`gtm`/`strategy`/`team`), `confidence` (`high`/`medium`/`low`), and `impact` (1-10). Document with `assets/assumption_map_template.md`.

## References

Load the reference that matches the task — keep this file lean and pull detail on demand:

- **[references/methodology-and-tools.md](references/methodology-and-tools.md)** — the full 4-8 category tables with examples, the devil's advocate prompts, the 5-phase scoring/quadrant process, `assumption_tracker.py` usage and flags, output formats, troubleshooting, success criteria, and bibliography. Read when mapping or scripting assumptions.
- **[references/assumption-mapping-guide.md](references/assumption-mapping-guide.md)** — deep theory: Torres' four risks and the extended 8-category model with red flags per category, confidence calibration techniques (evidence-based, Five Whys, pre-mortem check), the prioritization matrix with tripwires, and assumption-to-experiment mapping. Read for the underlying framework.
- **[references/red-flags.md](references/red-flags.md)** — anti-patterns (assumption inflation, miscategorization, confidence without evidence) with bad/good examples anchored in Torres' categories. Read before sharing an assumption map.

## Scope & Limitations

**In Scope:** systematic assumption identification using PM/Designer/Engineer devil's advocate perspectives; 8-category risk classification; quantitative scoring with Impact x (1 - Confidence); quadrant classification with suggested validation methods; assumption registry with priority sorting and action plans.

**Out of Scope:** running validation experiments (`brainstorm-experiments/`); product strategy or roadmap decisions (`execution/outcome-roadmap/`); technical feasibility deep-dives (`engineering/` skills); financial modeling for viability (`finance/` skills).

**Important Caveats:** confidence levels map to fixed numeric values (0.8/0.5/0.2) — a simplification of continuous confidence; the "high impact" threshold is 7/10, adjustable for your risk tolerance; assumption mapping works best collaboratively (Product Trio), not solo.

## Integration Points

| Integration | Direction | Description |
|------------|-----------|-------------|
| `brainstorm-ideas/` | Receives from | Ideas generated become the subjects whose assumptions are mapped |
| `brainstorm-experiments/` | Feeds into | "Test Now" assumptions become hypotheses for experiment design |
| `pre-mortem/` | Complements | Pre-mortem catches risks that assumption mapping may miss (especially elephants) |
| `execution/create-prd/` | Feeds into | Validated assumptions populate the PRD Assumptions section (Section 7) |
| `execution/brainstorm-okrs/` | Feeds into | Viability assumptions inform OKR key result selection and confidence levels |
| `senior-pm/` | Feeds into | High-impact assumptions feed into portfolio risk registers |

## What I Need You to Do

First, detect which platform I'm using (Claude.ai, ChatGPT, etc.) and follow the matching instructions below.

### If I'm on Claude.ai:

Walk me through these exact steps:

1. **Create the Project:** Tell me to go to **claude.ai > Projects > Create project** and name it **"Identify Assumptions"**

2. **Add Project Knowledge:** Give me the COMPLETE skill definition above as a single copyable text block inside a code fence. Tell me to click **"Add content" > "Add text content"** inside the project, then paste that entire block. Do NOT say "paste from above" -- give me the actual text to copy right there.

3. **Set Custom Instructions:** Tell me to open project settings and paste this exact instruction:
   "You are an expert Identify Assumptions in the Project Management domain. Use the project knowledge as your expertise. Follow the workflows, frameworks, and templates defined there. Always provide specific, actionable output."

4. **Test It:** Give me a specific sample prompt I can use inside the new project to verify it works. Pick a real task from the skill's workflows.

### If I'm on ChatGPT:

Walk me through these exact steps:

1. **Create a Custom GPT:** Tell me to go to **chatgpt.com > Explore GPTs > Create**
2. **Configure it:**
   - Name: **"Identify Assumptions"**
   - Description: "Assumption mapping expert that identifies, categorizes, and prioritizes product assumptions across 4-8 risk categories using devil's advocate analysis."
   - Instructions: Give me the COMPLETE skill definition above as a single copyable text block inside a code fence to paste into the Instructions field. Do NOT say "paste from above."
3. **Test It:** Give me a sample prompt to verify it works.

### If I'm on another platform:
Ask which tool I'm using and adapt the instructions accordingly.

## Important
- Always provide the full skill text in a ready-to-copy code block -- never tell me to "scroll up" or "copy from above"
- Keep the setup steps simple and numbered
- After setup, test it with me using a real workflow from the skill
