ob-userstory

name	ob-userstory
description	Parse GitHub Issue URL and create OpenSpec change. Use when user provides a GitHub Issue URL.
license	MIT
compatibility	Requires openspec CLI and gh CLI.
metadata	{"author":"copilots","version":"1.1"}

ALL GitHub data MUST come from gh CLI. NEVER use webfetch, HTTP requests, or browser MCP tools to fetch GitHub URLs, even if gh CLI fails. If gh is unavailable, report it as a blocker.

GitHub CLI Setup (One-Time)

gh auth login
# Follow prompts, authenticate via browser or token

Verify:

gh auth status

---

Steps

1. Extract owner, repo, and issue number from URL

   • https://github.com/{owner}/{repo}/issues/42 → owner: {owner}, repo: {repo}, number: 42

2. Fetch Issue, always pass --repo explicitly, never rely on git context:

   gh issue view 42 --repo {owner}/{repo} --json number,title,body,labels,milestone,state
   

   If this returns an auth error or 404, report as a blocker, do NOT fall back to webfetch or web search.

3. Extract Key Fields from JSON response:

   • number → Issue number
   • title → Title
   • body → Description / acceptance criteria
   • labels → Labels
   • milestone → Milestone / sprint equivalent
   • state → State (open/closed)

4. Create OpenSpec Change

   openspec new change "gh-{number}-{slug}"

Full GitHub CLI Reference

# Read issue
gh issue view <number> --repo {owner}/{repo}

# List open issues

Screenshot / Image Strategy

Never embed images as attachments. Save to openspec change folder and reference via GitHub blob URL pinned to commit SHA.

Save location

openspec/changes/{change-name}/images/{screenshot}.png

Blob URL format (preferred: keep ?raw=true when embedding in markdown)

https://github.com/{owner}/{repo}/blob/{sha}/openspec/changes/{change}/images/{file}.png?raw=true

---

URL Formats Reference

# Issue
https://github.com/{owner}/{repo}/issues/{number}

# PR
https://github.com/{owner}/{repo}/pull/{number}

# Blob file
https://github.com/{owner}/{repo}/blob/{sha}/{path}

Output Format

## Issue Parsed

**Issue:** #{number}
**Title:** {title}
**State:** {state}
**Milestone:** {milestone}

**Change Created:** gh-{number}-{slug}

After outputting the above, the lead MUST load the ob-plan-propose skill (interactive mode) to generate the proposal, specs, and tasks. After it completes, STOP and ask the user: "Ready to implement? (yes/no)", do NOT load ob-plan-apply until confirmed.
