PR discussion summary mode

Updated Jul 27, 2026

Generate an AI-assisted summary of PR review discussions grouped by file and severity:

frankie \
  --summarize-discussions \
  --pr-url https://github.com/owner/repo/pull/123 \
  --token ghp_example \
  --ai-api-key sk_example

The CLI output groups discussion threads by file and severity, and prints a stable Frankie deep-link token for each host-neutral review-view reference:

PR discussion summary for #123

File: src/main.rs
  Severity: high
    - Handle panic path
      Rationale: Root discussion flagged an unchecked failure path.
      Link: frankie://review-comment/1?view=detail

Summary generation works at the discussion-thread level. Replies are collapsed into the root thread, so a reply does not create a second summary item with its own reference.

If the selected pull request has no review comments, Frankie returns an explicit error instead of printing an empty summary.
