Create Feature Branch

Create Feature Branch

Create a new feature branch for the user's next task in the intended repository.

Quick start

1. Confirm the target repository root unless the calling workflow already resolved it.
2. Ask what feature the branch should represent unless the user already gave a clear branch name.
3. Turn the answer into a short branch name such as feature/<name>.
4. Switch into the target repository root with Push-Location / Pop-Location or an equivalent directory stack.
5. Update the local main branch to the latest state and create the new branch there.

Workflow

1. Resolve the repository context.
   • If a calling workflow already resolved a repository root or repository id, treat it as binding.
   • If multiple repositories could apply, ask one narrow question before running any git command.
   • Run git rev-parse --show-toplevel in the working directory and stop if it does not match the intended repository.
   • Never rely on the shell's inherited current directory when the repository matters.
2. Confirm the branch target.
   • If the user gives a feature description, convert it to a concise kebab-case slug.
   • If the user gives an exact branch name, use it when it matches the repository convention.
   • If the repository uses a different prefix than feature/, follow that convention.
3. Sync main in the target repository.
   • Use Push-Location / Pop-Location or an equivalent directory stack when switching into the target repository root.
   • Switch to the local main branch in that repository.
   • Update it from the default remote with a non-interactive command.
4. Create the feature branch.
   • Create the branch from the updated main branch in the target repository.
   • Switch to the new branch immediately.
5. Report the result.
   • Tell the user the final branch name.
   • Tell the user which repository root the branch was created in.
   • Surface blockers such as repository mismatches, uncommitted changes, missing remotes, or pull failures instead of guessing.

Notes

• Never run git against agent-harness unless that repository is intentionally the target.
• Use non-interactive git commands.
• Do not invent a branch name when the requested feature is still ambiguous.
• Only perform the git steps when the user has explicitly asked for branch creation.
