What changes does the diff panel show?

All uncommitted changes in the worktree: modified and deleted files via git diff HEAD, plus untracked files shown as new additions.

When does the comment button appear?

The + button shows up on diff lines only when an AI agent session is running in the worktree. Without an active session, you can still view the diff but not send comments.

Can I review GitHub pull request diffs in Canopy?

The diff panel shows local changes, not remote PR diffs. You can create a PR from Canopy once the changes are ready, but the review workflow is designed for reviewing local AI output.

review AI-generated code with inline feedback

Canopy shows all uncommitted changes in a diff panel. Click any line to write a comment, and Canopy sends it directly to the running Claude Code or Gemini CLI session. This lets you do code review for AI, not the other way around.

diff of local changes

The diff panel lists modified, added, and deleted files with their line counts. Hunks are collapsible, and you can search across all changes. Untracked files show up as full additions.

inline comments sent to the AI agent

Hover a diff line and click the + button to open a comment form. Canopy wraps the comment with three lines of surrounding context, the file path, and the line number, then writes it to the active agent session.

GitHub pull request creation

When you are ready to merge, open a PR from Canopy. The PR creation dialog supports title, body, base branch, and draft mode. Canopy tries the GitHub GraphQL API first and falls back to the gh CLI.
