# om-ux-shape

Turns a vague feature or screen idea into one decided direction: what you build, for whom, and how it behaves in the interface.

## What it does

The skill runs in three modes. Shape takes a raw idea or request, Review digs into an existing concept, flow or prototype, and Handoff fills in behaviour once the direction is settled. Combining modes is fine only when the task genuinely spans them.

Under the hood it is a step-by-step process with reference files: `references/decision-framework.md` for Shape and Review, `references/ai-interaction.md` and `references/hai-guidelines.md` when AI is part of the feature, `references/human-value-metrics.md` for metrics, `references/report-templates.md` before writing anything down, and `references/quality-rubric.md` before delivery. Facts, inferences, assumptions and open questions stay in separate buckets, so guesses never pass as research. The output is a filled report template with screen names, component names and the actual labels and error messages, not a description of what they might say.

One constraint is baked into the process: if AI is involved, it has to clear a necessity gate before anything else is considered. That makes the whole apparatus overkill for a small copy tweak, and the skill says as much — small tasks should not carry the full cycle.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add open-mercato/skills --skill om-ux-shape -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/om-ux-shape/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/om-ux-shape/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add open-mercato/skills --skill om-ux-shape -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/om-ux-shape/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add open-mercato/skills --skill om-ux-shape -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/om-ux-shape/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install open-mercato/skills om-ux-shape
```

2. **Manually: put the files in place**
- File: `.github/skills/om-ux-shape/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add open-mercato/skills --skill om-ux-shape -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/open-mercato/skills --path skills/om-ux-shape
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/om-ux-shape/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add open-mercato/skills --skill om-ux-shape -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/open-mercato/skills/tree/HEAD/skills/om-ux-shape/SKILL.md

## When to use it
- decide whether a feature needs AI at all
- map a flow into empty, loading, error and success states
- cut an overcomplicated scenario down to one path
- separate facts from assumptions before a team discussion
- prepare a design handoff with real labels and messages

## Example prompts
- Shape an onboarding idea: reader is a developer with no context
- Review this flow and rank the findings by impact
- Direction is settled, do a Handoff: screen states and error copy

name: om-ux-shape

# Shape Useful Features

Turn ambiguity into a clear product decision before turning it into screens.
Connect user value, business value, interaction quality, AI behavior, delivery
constraints, and evidence in one lightweight process.

**Input** — a feature idea, an existing concept or product area, or a decided
direction that needs implementation detail.
**Output** — one filled shape from `references/report-templates.md`.

## Choose the mode

- **Shape** for a vague opportunity, request, or feature idea. The default.
- **Review** for an existing concept, flow, design, prototype, or product area
  (including a whole module handed over by `om-ux-review-pr`).
- **Handoff** when the direction is decided and implementation-ready behavior
  is what is missing.

Combine modes only when the request genuinely spans them, and never make a
small task carry the full process.

## Who reads the result

Establish this before writing, because it decides how concrete the output must
be. Ask when it is unclear, otherwise **default to the least-context reader**:
someone who will build or draw this, does not know the design system, and was
not in the conversation. Write for them. A senior designer can skim a concrete
answer; nobody can build an abstract one.

## Required reading

These are not optional background. When the condition is met, load the
reference before finishing the step: skipping it produces the failure this
skill exists to prevent, an answer that sounds reasonable and decides nothing.

| Condition | Load |
|---|---|
| Shape or Review mode | `references/decision-framework.md` |
| AI is proposed, implied, or already present | `references/ai-interaction.md`, then `references/hai-guidelines.md` and `references/reward-and-mental-models.md` for whatever passed the gate |
| Outcomes or validation metrics are being defined | `references/human-value-metrics.md` |
| Before writing any result | `references/report-templates.md` |
| Before delivering any result | `references/quality-rubric.md` |

`references/foundations.md` explains the rationale behind the process; read it
only when adapting the process or evolving this skill.

## Operating principles

1. Start from the consequential problem, not the requested interface.
2. Treat requirements as claims until evidence supports them.
