name: Using GitHub CLI (gh) description: Master GitHub CLI workflow for issues, repos, search, and APIs. Use when creating/reading GitHub issues, searching repos, querying GitHub data, or automating GitHub tasks. Focus: gotchas, key workflows with "look at past examples" pattern, practical APIs.

Using GitHub CLI (gh)

Clear, focused guide to GitHub CLI gotchas and key workflows for issues, repos, search, and APIs.

---

🚨 Critical Gotchas

1. Search with Exclusions Needs --

# ❌ WRONG
gh search issues "my-query -label:bug"

# ✅ RIGHT
gh search issues -- "my-query -label:bug"

Shell interprets -label:bug as a flag without --.

2. JSON Output Requires Field Names

# ❌ WRONG
gh pr list --json

# ✅ RIGHT
gh pr list --json number,title,author

API must know which fields to fetch.

3. Repo Context Defaults to Current Directory

# ❌ WRONG - fails if not in repo
gh pr list

# ✅ RIGHT
gh pr list -R owner/repo
GH_REPO=owner/repo gh pr list

4. Token Scope Issues (Silent Failures)

Check your token scopes before automating:

gh auth status
# Needed: repo, read:org, gist, workflow, admin:public_key

5. API Placeholder Variables Don't Expand Env Vars

# ❌ WRONG
gh api /repos/$OWNER/$REPO/issues

# ✅ RIGHT - use gh placeholders
gh api /repos/{owner}/{repo}/issues

4 Key Workflows

Workflow 1: CREATE ISSUE

Step 0: Find the repository

# If it's a package, check metadata first
pip show package-name | grep "Home-page"

# Verify with search (repo might be under different org)
gh search repos "package-name" --limit 5

ALWAYS: Look at past examples in the repo first

# Step 1: Search for similar issues (avoid duplicates)
gh search issues --repo owner/repo "your search terms" --limit 10

# Step 2: View format of 2-3 recent similar issues
gh issue view --repo owner/repo [issue-number]

# Step 3: Identify the pattern (sections, detail level, tone)

Keep It Short

Maintainers are overwhelmed. Good issues are:

• Clear title - One line describing the problem
• Brief description - 1-2 sentences
• Minimal repro - Smallest code/steps to reproduce
• Short environment - OS, version (one line)

Create Issue

# For multi-section issues, use --body-file
gh issue create --repo owner/repo \
  --title "Bug: X breaks when Y" \
  --body-file body.md  # Clean content only, no metadata

# For short issues, inline is fine
gh issue create --repo owner/repo \
  --title "Clear, searchable title" \
  --body "Brief description.

Repro steps.

Environment: macOS 14.6.0"

Verify Bug Reports

Before submitting:

• Read the actual code being referenced
• Test reproduction steps
• Confirm exact trigger (e.g., Ctrl+Q vs Ctrl+D)

Key Points:

• Search for duplicates BEFORE creating
• Look at 2-3 recent issues to match repo style
• Keep it concise - respect maintainers' time
• Verify behavior by reading code/testing

Workflow 2: READ ISSUE

Get full issue with comments

# View issue with all comments
gh issue view --repo anthropics/claude-code [number] --comments

# Extract specific information
gh issue view --repo anthropics/claude-code [number] \
  --json title,body,state,author,labels

# List issues assigned to you
gh issue list --assignee=@me --json number,title,state

Common Queries

# Issues waiting on you
gh issue list --search 'is:open assignee:@me'

# Issues with specific label
gh issue list --search 'is:open label:bug' --limit 20

# Recent issues (last 7 days)
gh issue list --search 'is:open updated:>=7.days.ago' --limit 10

---

Workflow 3: READ REPOSITORY INFO

Get repo details

# View repo metadata
gh repo view --repo anthropics/claude-code --json name,description,url

# Check recent issues/PRs
gh issue list --repo anthropics/claude-code --limit 10
gh pr list --repo anthropics/claude-code --limit 10

# View available labels
gh label list --repo anthropics/claude-code

Find Repo Context

# Get owner and repo from current directory
gh repo view --json owner,nameWithOwner

# Use in other commands
REPO=$(gh repo view --json nameWithOwner --jq '.nameWithOwner')
gh issue list --repo $REPO

---

Workflow 4: SEARCH

Search syntax (remember the --)

# Search issues with filters
gh search issues -- "your query -label:wontfix" --limit 15

# Search specific repo with multiple criteria
gh search issues --repo anthropics/claude-code "is:open label:bug type:issue"

# Search code
gh search code "function main" --language python --limit 10

# Search repos
gh search repos "claude-code" --owner anthropics --limit 5

Advanced Filters

# Issues: is:open, is:closed, label:bug, author:username, assignee:@me
# PRs: is:open, is:draft, review:approved, review:requested
# More: https://docs.github.com/en/search-github/searching-on-github/searching-issues-and-pull-requests

# Examples
gh search issues -- "is:open label:enhancement -label:duplicate"
gh search issues -- "is:closed sort:updated-desc"
gh pr list --search 'is:open review:requested'

Key API Commands

Direct API Access (when gh commands aren't enough)

# Get user info
gh api user | jq '.login, .name'

# List issues with pagination
gh api --paginate /repos/{owner}/{repo}/issues | jq '.[] | .number'

# GraphQL query
gh api graphql -f query='{ viewer { name login } }'

# Create something
gh api -f title="New Issue" -f body="Description" /repos/{owner}/{repo}/issues

Output Formatting

# JSON for scripting
gh issue list --json number,title,state

# Extract fields with jq
gh pr list --json author,title --jq '.[].author.login'

# Custom formatting (if needed)
gh pr list --json number,title \
  --template '{{range .}}#{{.number}}: {{.title}}{{"\n"}}{{end}}'

---

When Things Go Wrong

# Check authentication
gh auth status

# Token scope issues
# ❌ Operations fail silently if scopes are missing
gh auth status  # Shows current scopes
# If missing, run: gh auth login --scopes repo,gist,workflow

# Enable debug output
GH_DEBUG=1 gh issue list

# Repository not found?
# Use -R flag: gh issue list -R owner/repo

Contributing New Workflows

When you discover a useful automation pattern:

1. Save it to ~/.claude/skills/using-github-cli/workflows/gh-pattern-name.sh
2. Add documentation comment at top
3. Update WORKFLOWS.md with description
4. Next session will have access to it!

See WORKFLOWS.md and workflows/gh-status-dashboard.sh for examples.
