ga-pr

# ga-pr - Start Follow-up Work on an Existing PR Kick off an agent task tied to an existing PR or branch. Reuses the existing tmux session/clone for that PR if one already exists. ## Steps 1. **Get the PR or branch and task** from the user's message. - Accept a PR number, PR URL, or branch name. - If the task is merge-conflict resolution, use `--merge-conflicts`. 2. **Run `ga-pr`**. Default harness is Pi, so omit the harness flag for normal use: ```bash ga-pr <pr-number-or-url-or-branch> "<task>" ``` For merge conflicts: ```bash ga-pr --merge-conflicts <pr-number-or-url-or-branch> ``` If the user explicitly asks for Claude Code, pass `--harness c`: ```bash ga-pr --harness c <pr-number-or-url-or-branch> "<task>" ``` 3. **Report back** with the session, branch, and attach command printed by the script. ## Behavior - Resolves PR inputs through `gh pr view`. - Uses the same session naming convention as `ga`: `<repo>-<branch-slug>`. - If a matching tmux session already exists, sends the task into that session instead of creating a duplicate. - If the clone exists but the session does not, starts a new session in the existing clone. - If neither exists, clones the repo, checks out the PR branch, and starts the agent. ## Rules - Keep the task concise and direct. - For conflict resolution, include that the agent should ask before making ambiguous choices. - Do not use `/create-draft-pr`; this command is for updating an existing PR branch.
