Behavior Guidelines

1. Always check auth first — run gh auth status before complex operations. If not logged in, run gh auth login.
2. Prefer --json + --jq for scripting — never parse human-readable gh output with grep/awk. Use structured JSON output.
3. Use --repo owner/repo for cross-repo ops — avoid cd-ing into directories when you can target repos directly.
4. Prefer gh pr create over manual push + web UI — it handles branch pushing, PR creation, and linking in one step.
5. Use --web to hand off to browser — when the user needs to fill forms or review visually, open in browser instead of guessing.

Core Workflows

Pull Requests

# Create PR (interactive — fills title/body from commits)
gh pr create

# Create with details
gh pr create --title "feat: add dark mode" --body "Closes #42"

# Draft PR
gh pr create --draft --title "WIP: refactor auth"

# Review and merge
gh pr review 123 --approve
gh pr merge 123 --squash --auto

# Check PR status
gh pr checks 123
gh pr list --author "@me"

Issues

# Create issue
gh issue create --title "Bug: login fails" --label "bug" --assignee "@me"

# List and filter
gh issue list --label "bug" --state open
gh issue list --search "is:open label:bug created:>2024-01-01"

# Close with comment
gh issue close 42 --comment "Fixed in #123"

CI / Actions

# Watch current run
gh run watch

# List failures
gh run list --branch main --status failure --limit 10

# View logs
gh run view 12345678 --log

# Re-run failed jobs
gh run rerun 12345678 --failed

# Trigger workflow manually
gh workflow run deploy.yml --field environment=staging

JSON Scripting Patterns

# List PR titles and numbers
gh pr list --json number,title --jq '.[] | "\(.number): \(.title)"'

# Check if all PR checks passed
gh pr checks 123 --json name,state --jq '[.[] | select(.state != "SUCCESS")] | length == 0'

# Find failing workflow runs
gh run list --json status,name,url --jq '.[] | select(.status == "failure") | .url'

Common Troubleshooting

Problem	Fix
gh: command not found	brew install gh or see install guide
Not logged in	gh auth login
Permission denied	gh auth refresh --scopes repo,workflow
Wrong repo targeted	Add --repo owner/repo or cd into the repo
Stale token	gh auth refresh
