Issue Crafting

Domain skill for creating high-quality GitHub issues that describe what should happen without prescribing how.

Iron Law

ISSUES DESCRIBE OUTCOMES, NEVER IMPLEMENTATIONS. If the issue says "how," rewrite it.

The moment an issue prescribes a method, it constrains the solution space and biases the implementer.

Solution-Agnostic Principles

Issues must describe outcomes, not implementations:

• Good: "Users can reset their password via email"
• Bad: "Add a reset_password method to UserController that sends a Postmark email"

Acceptance criteria must be verifiable without knowing the code:

• Good: "Resetting a password with a valid token changes the stored password"
• Bad: "The reset! method updates the password_digest column"

Anti-Patterns in Issue Writing

Do NOT:

• Include file paths, function names, or class names in acceptance criteria
• Write acceptance criteria that can only be verified by reading code
• Create issues without checking for duplicates first
• Use vague criteria like "improve performance" or "make it better"
• Bundle unrelated changes into a single issue

Requirements Gathering

Collect these four elements. For any missing context, use the AskUserQuestion tool with contextual options to ask about the specific gap (e.g., "What's the current behavior?").

1. Context: Background and motivation — why is this needed?
2. Current State: What's happening now? What's the problem?
3. Objective: What should be achieved? Describe the outcome.
4. Acceptance Criteria: Observable behaviors that prove completeness.

Duplicate Detection

Always search before creating:

REPO=$(gh repo view --json nameWithOwner --jq '.nameWithOwner')
# Search open issues
gh issue list --state open --search "KEYWORDS" --limit 10
# Search closed issues (might already be solved)
gh issue list --state closed --search "KEYWORDS" --limit 5

If matches found, present them to the user before proceeding.

Label Discovery

Never hardcode labels — fetch dynamically:

gh label list --json name,description --limit 50

Select labels based on issue content. Common mappings:

• Bug reports → bug
• New features → enhancement
• Documentation → documentation
• Security issues → security

Milestone Check

gh api repos/$REPO/milestones --jq '.[] | "\(.number): \(.title)"'

Offer milestone assignment if milestones exist.

Issue Body Structure

## Context
{Background and motivation}

## Current State
{What's happening now — observable behavior}

## Objective
{What should be achieved — outcomes, not methods}

## Acceptance Criteria
- [ ] {Observable behavior 1}
- [ ] {Observable behavior 2}
- [ ] {Observable behavior 3}

Verification

After creation, verify: gh issue view <N> --json number,title,state,labels

The issue should:

• Have a clear, searchable title
• Contain no file paths or implementation details in the body
• Have acceptance criteria that describe what, not how
• Have appropriate labels from the repository's label set
