Copilot Review Fixer

Wraps the task-agent:copilot-review-fixer sub-agent so it can be invoked as a workflow step.

Arguments (key=value form):

• pr_url=<url> — full GitHub PR URL (e.g. https://github.com/owner/repo/pull/42). Required.
• repo=<owner/repo> — repository in owner/repo format. Required.
• branch=<branch> — branch name the PR is on. Required.

What to do

Step 1 — Parse arguments

Parse pr_url, repo, and branch from the invocation arguments.

Derive:

• OWNER and REPO_NAME from repo (split on /)
• PR_NUMBER from the last path segment of pr_url

If any required argument is missing or cannot be parsed, stop and report the error clearly.

Step 2 — Prepare the local clone

Reuse the task-agent workdir convention so the clone is shared with a preceding task-agent step in the same workflow:

WORKDIR="${TASK_AGENT_WORKDIR:-$(python3 -c 'import os,tempfile;print(os.path.join(tempfile.gettempdir(),"task-agent"))')}"
LOCAL_PATH="$WORKDIR/$REPO_NAME"
if [ -d "$LOCAL_PATH/.git" ]; then
  git -C "$LOCAL_PATH" fetch origin
  git -C "$LOCAL_PATH" checkout "$BRANCH"
  git -C "$LOCAL_PATH" reset --hard "origin/$BRANCH"
else
  mkdir -p "$WORKDIR"
  git clone "https://github.com/$OWNER/$REPO_NAME.git" "$LOCAL_PATH"
  git -C "$LOCAL_PATH" checkout "$BRANCH"
fi

Detect the default branch:

DEFAULT_BRANCH=$(git -C "$LOCAL_PATH" symbolic-ref refs/remotes/origin/HEAD 2>/dev/null | sed 's|refs/remotes/origin/||')
DEFAULT_BRANCH="${DEFAULT_BRANCH:-main}"

Step 3 — Spawn the sub-agent

Spawn the copilot-review-fixer sub-agent via the Agent tool (subagent_type: task-agent:copilot-review-fixer), passing all resolved values in the prompt so the agent can substitute them for OWNER, REPO_NAME, PR_NUMBER, BRANCH, LOCAL_PATH, and DEFAULT_BRANCH.
