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, settle the inputs below. When one is missing or vague and would change the result, ask about it; when it wouldn't, use a sensible default and say which one you used.

- **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).

Ask about the two or three inputs that matter most for this request, not the whole list. If the user wants a result straight away, produce it and state your assumptions at the top.

## Workflow

1. Settle the Clarify First inputs, then surface assumptions from PM, design and engineering angles (prompts in `references/methodology-and-tools.md`).
2. Rate each with `impact` (1-10) and `confidence`, citing the evidence behind every `high`.
3. Run `assumption_tracker.py`; it ranks by `Risk Score = Impact x (1 - Confidence)` and places each in a quadrant.
4. Done when Test Now holds about 20% of the map, each Test Now item has an owner, a date and a test, and the tool exits 0.

```bash
python3 project-management/discovery/identify-assumptions/scripts/assumption_tracker.py project-management/discovery/identify-assumptions/assets/sample_assumptions.json             # exit 0
python3 project-management/discovery/identify-assumptions/scripts/assumption_tracker.py project-management/discovery/identify-assumptions/assets/sample_assumptions_overloaded.json  # exit 1
python3 project-management/discovery/identify-assumptions/scripts/assumption_tracker.py --demo --format json
```

Each assumption needs `description`, `category` (`value`/`usability`/`viability`/`feasibility`/`ethics`/`gtm`/`strategy`/`team`), `confidence` (`high`/`medium`/`low`), and `impact` (1-10). Confidence maps to fixed values (high 0.8, medium 0.5, low 0.2) and drives every ranking; impact 7+ counts as high. Quadrants: Test Now (high impact, low or medium confidence), Proceed (high impact, high confidence), Investigate (lower impact, low confidence), Defer (the rest). Exit codes: 0 sound map, 1 Test Now holds more than about 20% (round(0.2 x n), minimum 1), 2 bad input. Document with `assets/assumption_map_template.md`.

## Anti-Patterns

### Everything rated risky
**Mistake:** The map lists dozens of assumptions, nearly all high impact and low confidence, so nothing can be tested in order.
**Why it happens:** Rating an assumption low-risk feels like tempting fate.
**Instead:** Keep no more than about 20% of assumptions in the Test Now quadrant. If more land there, re-score `impact` and `confidence` against real evidence until the load-bearing ones stand out.

### Beliefs marked as facts
**Mistake:** "Users want a faster checkout" is rated `high` confidence because "we know this," with no evidence cited.
**Why it happens:** The most dangerous assumptions feel obviously true.
**Instead:** Cite the evidence for every `high` confidence rating. "We know this" is not evidence. Without a source, rate it `low` and let `assumption_tracker.py` rank it.

### Testing the easiest assumption first
**Mistake:** The team tests the assumption with the easiest experiment, not the one the idea depends on most.
**Why it happens:** Hard experiments are uncomfortable, and easy ones give quick wins.
**Instead:** Rank by `Risk Score = Impact x (1 - Confidence)` and test the top three first, even when the experiment is hard. Give each one an owner and a date.

Nine more, each with a bad and a good example: `references/red-flags.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.
