Implement a GitHub issue

This skill wraps the Standard Workflow defined in AGENTS.md. Run the steps below before and after that workflow.

Before the standard workflow

A. Read the issue in full:

gh issue view {number}

If gh is not authenticated, stop and ask the user to authenticate before continuing.

B. Check/create the branch:

• If on main: usethis::pr_init("fix-{number}-{description}")
• Branch format: fix-{number}-{description}
  • Parts separated by hyphens; {description} uses snake_case
  • Example: fix-42-validate_input
• If a branch already exists for this issue, check it out instead

Run the Standard Workflow from AGENTS.md

Steps 1–9 of the Standard Workflow are the core development loop.

After the standard workflow passes, also verify code coverage for the edited files. Ask the user before bumping the version number with usethis::use_version("dev").

After the standard workflow

C. Commit and push:

1. Review commits already on this branch (not on main) — these are all part of the same PR and should inform the PR description:

   git log main..HEAD --oneline
   

2. Stage and commit all changes:

   git add -A
   git commit -m "{short imperative summary}"
   

3. Push and open the PR:

   gh pr create --fill
   

   Use --title and --body explicitly if --fill produces an inadequate description.

This step may be overridden — the user may ask you to stop before committing, handle the push themselves, or complete only part of the workflow. Always follow explicit user instructions over these defaults.
