## What it does
The skill gets the product context straight, then records it in `${SPECS_DIR}/product-brief.md`: the problem, the evidence behind it, scope, decisions already made, and the next uncertainty worth resolving. Three modes cover the usual starting points — `existing` for a product with real users, `client` for material that came from a client, `own` for your own idea. Pass `--mode` to pick one, or let the skill infer it and confirm with you in the opening exchange.
One rule is hard: never invent research, user behaviour, quotes or measurements. A missing fact stays unknown or becomes a labelled hypothesis, and a decision nobody confirmed stays a `proposal`. Material the current decision actually needs goes on a collection plan; empty sections stay short. Sessions run in rounds — two or three independent questions, or a single round under `--quick`. The draft then passes a fidelity and compression check, and a fresh-context subagent reads it independently. Without subagents the same checks run inline, and the skill says so.
The brief is not a document that sits in a folder. Its Non-goals, Business rules and Decisions sections form the protected contract that `om-code-review` and `om-ux-review-pr` enforce under `SDLC.md`, so sloppy claims here come back at review time. Config is optional; without it the skill falls back to `.ai/specs`. Tracker operations, when a tracker is configured, are read-only.
## Install
### Claude Code (native platform)
1. **Skills CLI (Vercel)**
```bash
npx skills add open-mercato/skills --skill om-discover -a claude-code
```
2. **Manually: put the files in place**
- File: `~/.claude/skills/om-discover/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/om-discover/
### Codex
1. **Skills CLI (Vercel)**
```bash
npx skills add open-mercato/skills --skill om-discover -a codex
```
2. **Manually: put the files in place**
- File: `.agents/skills/om-discover/SKILL.md` — For all projects use ~/.agents/skills/
### Cursor
1. **Skills CLI (Vercel)**
```bash
npx skills add open-mercato/skills --skill om-discover -a cursor
```
2. **Manually: put the files in place**
- File: `.cursor/skills/om-discover/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/
### GitHub Copilot
1. **GitHub CLI**
```bash
gh skill install open-mercato/skills om-discover
```
2. **Manually: put the files in place**
- File: `.github/skills/om-discover/SKILL.md`
### Gemini CLI
1. **Skills CLI (Vercel)**
```bash
npx skills add open-mercato/skills --skill om-discover -a gemini-cli
```
2. **Platform CLI**
```bash
gemini skills install https://github.com/open-mercato/skills --path skills/om-discover
```
### Windsurf (Devin Desktop)
**Manually: put the files in place**
- File: `.devin/skills/om-discover/SKILL.md` — The legacy .windsurf/skills/ path still works
### OpenCode
**Skills CLI (Vercel)**
```bash
npx skills add open-mercato/skills --skill om-discover -a opencode
```
### Claude.ai
**Claude.ai**

## When to use it
- pin down the problem before writing product code
- separate confirmed facts from hypotheses in a brief
- refresh an existing brief while keeping old ids and decisions
- pull repository and tracker context before asking the user anything
- set non-goals and business rules that code review can enforce
## Example prompts
- om-discover --mode existing — look at what current users struggle with and refresh the brief
- om-discover --mode client --refresh — update the brief from the client's material, keep the existing ids
- om-discover --quick — one round of questions on my idea, then we decide whether to continue

name: om-discover
description: Guide a product discovery conversation and write product-brief.md with the problem, evidence, scope, decisions, and the next uncertainty to resolve. Use for product discovery, defining a product, or refreshing its brief. Supports existing products, client ideas, and own ideas.

# Discover
Establish product context that later skills can use without guessing. Help the user make the current decision, then record the basis, scope, rules, and unresolved risks in `${SPECS_DIR}/product-brief.md`. `om-brainstorm` handles an individual idea; this skill establishes or refreshes the product context it reads. The brief's Non-goals, Business rules and Decisions also supply the protected contract that `om-code-review` and `om-ux-review-pr` enforce under `SDLC.md`.
Never invent research, user behaviour, quotes, or measurements. A missing fact stays unknown or becomes an explicitly identified hypothesis. A human may choose to build with an untested assumption; that decision does not turn it into evidence. Decisions without human confirmation remain `proposal`. Material needed for the current decision goes on a collection plan; irrelevant empty sections need no research task.
## Arguments
- `{topic}` (optional): product or area to discover. When absent, ask what the brief is for.
- `--mode existing|client|own` (optional): use the stated mode; otherwise infer it from the material and confirm it with the opening decision frame.
- `--refresh` (optional): update an existing brief, preserving ids and superseded decisions.
- `--research ` (optional): raw material directory; default `${SPECS_DIR}/research`.
- `--quick` (optional): one round, normally two or three independent questions; inline skeptic; the same evidence, coherence, and compression checks. Use material already available, including flows. Defer details irrelevant to the next decision without creating research tasks. Further substantive questions require the user to choose to extend the session.
## Modes
Read `references/modes.md` for the selected mode. Modes guide where to look and what might matter; depth follows the current decision and its risks.
| Mode | Start from | Follow up when relevant |
|---|---|---|
