GitHub Issue Management Skill

This skill provides a structured approach to writing GitHub issues that communicate context, scope, and direction clearly.

Title Format (Required)

Issue titles must follow conventional commit format:

<type>(<scope>): <description>

Valid types: feat, fix, docs, style, refactor, perf, test, build, ci, chore, revert

Examples:

  • feat(auth): add OAuth2 login support
  • fix(api): resolve race condition in request handler
  • chore(deps): update dependencies to latest versions
  • docs(readme): add installation instructions

The script validates this format automatically. Use --skip-validation only if the repository uses a different convention.

The Why/What/How Framework

Every issue should answer three questions for the reader:

  • Why does this matter?
  • What exactly needs to happen?
  • How should it be approached?

This framework ensures issues are actionable and provide enough context for anyone picking them up.

Issue Template

Why

Explain the background and motivation:

  • Current state: What exists today? How does it work?
  • Bottleneck/Problem: What specific issue or limitation was identified?
  • Value: Why is solving this valuable? What insights, metrics, or improvements does it unlock?
markdown
## Why

Currently, [describe current state/behavior].

This causes [specific problem or bottleneck], which [impact on users/system/workflow].

Addressing this will [concrete benefit - improved metrics, unlocked capabilities, better UX].

What

Define the scope concretely:

  • Specific deliverable: What exactly needs to be built, fixed, or changed?
  • Boundaries: What is explicitly out of scope?
  • Success criteria: How do we know when this is done?
markdown
## What

[Verb] [specific thing] to [achieve outcome].

Scope:
- [In scope item 1]
- [In scope item 2]

Out of scope:
- [Explicitly excluded item]

How

Provide implementation direction:

  • Approach: High-level strategy or pattern to follow
  • Key files/components: Where changes will likely occur
  • Architecture sketch: Skeleton of the solution structure (not implementation details)
markdown
## How

Approach: [brief strategy - e.g., "Extend existing X pattern", "Add new Y component"]

Key areas:
1. [Component/file] - [what changes here]
2. [Component/file] - [what changes here]

Skeleton:
- [High-level step 1]
- [High-level step 2]
- [Integration point]

Acceptance Criteria

Keep acceptance criteria focused on integration and observable behavior:

markdown
## Acceptance Criteria

- [ ] [Observable behavior or state that confirms completion]
- [ ] [Integration with existing system works as expected]
- [ ] [Edge case or error condition handled]

Tips:

  • Write criteria that can be verified by running the system
  • Focus on "what" not "how" - avoid implementation details
  • Include integration points with existing functionality

Testing Plan

Keep testing plans succinct and focused on verification:

markdown
## Testing Plan

- [ ] [How to manually verify the change]
- [ ] [Key integration scenario to test]
- [ ] [Regression check if applicable]

Tips:

  • Tests added should integrate within existing test architeture
  • Prioritize integration testing over isolated unit tests
  • Include the command or steps to run verification
  • Note any existing tests that should continue passing

Scripts Reference

This skill includes Python scripts in scripts/ that wrap GitHub API operations. Run them with uv:

dump-tree Dump issue and sub-issues to markdown with frontmatter
push Push/sync issue from markdown file to GitHub
link Link two issues (parent/child relationship)
close Close an issue
comment Add a comment to an issue
labels Manage issue labels

uv run scripts/gh_issue.py comment owner/repo 123 "Progress update: ..."

# Close an issue
uv run scripts/gh_issue.py close owner/repo 123 --reason completed

Creating Issues

Preview Before Creation

By default, the script shows a preview and asks for confirmation before creating:

============================================================
ISSUE PREVIEW
============================================================

Repository: owner/repo
Title: feat(api): add caching to API responses
Labels: enhancement, performance

Body:
----------------------------------------
## Why
...
----------------------------------------

Create this issue?
  y = create issue
  n = cancel
  e = edit (saves to /tmp/issue-body.md for editing)
  • Press y to create the issue
  • Press n to cancel
  • Press e to save body to /tmp/issue-body.md for editing, then re-run

Use --yes or -y to skip confirmation (for automation).

Basic Creation

bash
# Initialize template
uv run scripts/gh_issue.py init --output /tmp/issue-body.md

# Edit the template with your content
# ... edit /tmp/issue-body.md ...

# Create the issue (will show preview first)
uv run scripts/gh_issue.py create owner/repo \
  --title "feat(api): add caching layer" \
  --body-file /tmp/issue-body.md

With Labels and Assignment

bash
uv run scripts/gh_issue.py create owner/repo \
  --title "feat(api): add caching layer to API responses" \
  --body-file /tmp/issue-body.md \
  --labels "enhancement,performance" \
  --assignees "@me" \
  --milestone "v2.0"

Adding to a Project

bash
uv run scripts/gh_issue.py create owner/repo \
  --title "Issue title" \
  --body-file /tmp/issue-body.md \
  --project "Project Name"

Linking Issues

Create a Sub-issue

bash
# Create a new issue linked to parent #10
uv run scripts/gh_issue.py create-sub owner/repo \
  --parent 10 \
  --title "feat(cache): implement caching middleware" \
  --body "## Why
Part of the caching initiative (#10).

## What
Implement the middleware layer for request caching."

Link Existing Issues

bash
# Link issue #42 as a sub-issue of #10
uv run scripts/gh_issue.py link owner/repo --parent 10 --child 42

Close Issue via Commit

Reference the issue number in a commit message to auto-close:

bash
git commit -m "Add caching middleware

Fixes #42"

Keywords that close issues: fixes, closes, resolves (followed by #issue_number)

Working with Sub-Issues and Cross-Repo References

List Sub-Issues

When an issue references sub-issues from other repositories, use list-subissues to find them all:

bash
uv run scripts/gh_issue.py list-subissues owner/repo 123

This command:

  • Fetches the issue timeline via GitHub API
  • Identifies all cross-referenced issues (including from other repositories)
  • Returns full repository paths (e.g., owner/other-repo#456)
  • Handles duplicates automatically

Output formats:

  • Table view (default): Shows reference, title, and state
  • JSON (--json): Machine-readable format for scripting

Dump Issue Tree

To save an issue and all its sub-issues as markdown files with YAML frontmatter:

bash
uv run scripts/gh_issue.py dump-tree owner/repo 123 thoughts/shared/issues/

This command:

  1. Fetches the parent issue and saves as {issue_number}-{safe-title}.md
  2. Lists actual sub-issues via GraphQL API (not just cross-references)
  3. Fetches each sub-issue with full metadata (assignees, milestone, etc.)
  4. Saves each as a markdown file with YAML frontmatter
  5. Creates directory: {issue_number}-{safe-title}/

Output format (frontmatter):

yaml
---
title: "feat(auth): add OAuth2 support"
repo: owner/repo
number: 123
state: open
labels:
  - enhancement
assignees:
  - username
milestone: "Q1 2026"
parent: owner/repo#100
created_at: 2026-01-14T12:00:00Z
author: username
url: https://github.com/owner/repo/issues/123
---

## Why
... actual body content (clean, no metadata) ...

Benefits:

  • Clean separation of metadata and content
  • Machine-parseable frontmatter
  • Round-trip editing: dump → edit → push back
  • GitHub body stays clean (no metadata pollution)

Push Issue from File

Push a markdown file with frontmatter back to GitHub:

bash
# Create new issue (no number in frontmatter)
uv run scripts/gh_issue.py push new-feature.md

# Update existing issue (has number in frontmatter)
uv run scripts/gh_issue.py push 123-existing-issue.md

# Skip confirmation
uv run scripts/gh_issue.py push issue.md --yes

The push command:

  1. Parses YAML frontmatter for metadata
  2. Uses body content as the GitHub issue body (clean, no metadata)
  3. Creates new issue if number is omitted
  4. Updates existing issue if number is present
  5. Applies labels, assignees, milestone, project from frontmatter
  6. Links to parent issue if parent is specified

Required frontmatter fields:

  • title: Issue title (must follow conventional commit format)
  • repo: Repository in owner/repo format

Optional frontmatter fields:

  • number: Issue number (omit for new issues)
  • labels: List of labels to apply
  • assignees: List of GitHub usernames
  • milestone: Milestone name or number
  • project: Project name to add issue to
  • parent: Parent issue reference (e.g., "owner/repo#123")

Round-Trip Workflow

The frontmatter format enables a powerful workflow:

bash
# 1. Export issue tree to local files
uv run scripts/gh_issue.py dump-tree owner/repo 123 ./issues/

# 2. Edit locally (modify body, add labels, change assignees, etc.)
$EDITOR ./issues/123-feature/456-sub-task.md

# 3. Push changes back to GitHub
uv run scripts/gh_issue.py push ./issues/123-feature/456-sub-task.md

Use cases:

  • Batch editing multiple issues offline
  • Template-based issue creation
  • Migrating issues between repositories
  • Version-controlled issue content
