MR Comment Handler

Find the open MR for the current branch and address its review threads using glab. Run all glab commands with elevated network access.

Prerequisites

• Ensure glab auth status succeeds (via glab auth login or GITLAB_TOKEN).
• Ensure glab is at least v1.80.4.
• When sandboxing blocks network calls, rerun with sandbox_permissions=require_escalated.
• Sanity check auth up front:

glab auth status

1) Resolve the MR for the current branch

Do a quick check so we know which MR we are about to operate on:

branch="$(git rev-parse --abbrev-ref HEAD)"
glab mr view "$branch" --output json

If this fails, the fetch script below will still try to locate the MR by source_branch.

2) Fetch unresolved discussions to /tmp

Use the local script to fetch MR discussions via glab api. This filters out bot/system-only threads and returns unresolved discussions when --open-comments is set.

skill_dir="<path-to-skill>"
branch="$(git rev-parse --abbrev-ref HEAD)"
safe_branch="${branch//\//_}"
out="/tmp/${safe_branch}_mr_open_discussions.json"
python "$skill_dir/scripts/fetch_comments.py" --open-comments --output "$out"

If you want the full payload (including resolved discussions), drop --open-comments.

3) Summarize, triage, and ask once

• Load the JSON and number each unresolved discussion.
• Start with a compact summary list instead of dumping full threads.
• Sort by: unresolved first (already filtered), then most recently updated.
• When possible, group or label by file path to reduce context switching.
• In the summary list, show: number, discussion id, author, file:line (if present), and a one-line summary.
• Ask for a batch selection in one shot. Accept: 1,3,5-7, all, none, or top N.
• If the user does not choose, suggest a small default set (for example top 3) with a short rationale.
• Only after selection, show the full thread and code context for the selected numbers.
• When showing code context, include 3 lines before and after and clearly mark the referenced line(s).

4) Implement fixes for the selected discussions

• Apply focused fixes that address the selected threads.
• Run the most relevant tests or checks you can in-repo.
• Report back with: what changed, which discussion numbers were addressed, and any follow-ups.

Notes:

• If glab hits auth or rate issues, prompt the user to run glab auth login or re-export GITLAB_TOKEN, then retry.
• If no open MR is found for the branch, say so clearly and ask for the MR URL or IID.
• Do not prompt “address or skip?” one comment at a time unless the user explicitly asks for that mode.
