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

Output shape:

```jsonc
{
  "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### Line 10 (by @another-reviewer) [outdated]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 use the TaskList tool and proceed to any remaining task.

## Rules

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