Fetch PR Comments

Fetch unresolved review comments, top-level review body comments, and PR conversation comments from a GitHub PR and present them in a readable summary. This is a read-only skill -- it does not evaluate, fix, or reply to any comments.

Step 1: Fetch Comments

Auto-detect owner, repo, and PR number from current branch if not provided. Then run scripts/fetch-pr-data.sh, which handles full pagination (review threads, inner comment pages for long threads, reviews, issue comments) and emits a single merged JSON document:

bash <skill-dir>/scripts/fetch-pr-data.sh <owner> <repo> <pr_number>

Output shape:

{
  "meta":          { "title", "url", "headRefName", "baseRefName" },
  "reviewThreads": [ { "id", "isResolved", "isOutdated", "comments": { "nodes": [ { "author", "body", "path", "line", "originalLine", "diffHunk" } ] } } ],
  "reviews":       [ { "author", "body", "state" } ],
  "issueComments": [ { "author", "body", "createdAt", "url" } ]
}

Filter review threads to unresolved only. Filter reviews to those with a non-empty body, excluding PENDING state (unsubmitted drafts). Filter issue comments to those with a non-empty body.

Step 2: Present Results

Display a summary header followed by comments grouped by file.

Summary header:

• PR title and link
• Branch: head -> base
• Total threads / unresolved threads

Top-level review comments (if any):

Show reviews with non-empty body before the file-grouped threads:

## Review Comments

### @reviewer (CHANGES_REQUESTED)
> Review body text here

### @another-reviewer (COMMENTED)
> Another review body here

Issue comments (if any):

Show PR conversation comments after review comments, ordered by createdAt:

## Issue Comments

### @commenter (2026-04-20)
> Issue comment body here

### @another-commenter (2026-04-21)
> Another issue comment body here

Inline threads grouped by file:

For each file with unresolved threads, show:

## `path/to/file.ts`

### Line 42 (by @reviewer)
```diff
<diffHunk from first comment>
```
> Comment body here

### Line 10 (by @another-reviewer) [outdated]
```diff
<diffHunk from first comment>
```
> First comment body
>
> **@reply-author:** Reply body

Formatting rules:

• Show top-level review body comments first, grouped under "Review Comments"
• Show PR conversation comments next, grouped under "Issue Comments", ordered by createdAt
• Then group threads by file path, in the order they appear
• Within each file, order threads by line number
• Show the diffHunk from the first comment in each thread as a fenced diff code block before the comment body. This is the code context the reviewer was looking at.
• For the line number, use line if available. Fall back to originalLine for outdated comments where line is null.
• Show all comments in a thread (the first is the original review comment; subsequent ones are replies)
• Mark outdated threads with [outdated]
• Use blockquotes for comment bodies
• For threads with multiple comments, show each comment with its author
• If there are zero unresolved threads, zero review body comments, and zero issue comments, say so and stop

Then call update_plan to mark this step completed and continue with the next step of the active workflow.

Rules

• If the user wants to fix or reply to comments, direct them to use $resolve-pr-comments.
