The gh pr comment command is part of the GitHub CLI toolset, allowing users to add, edit, or reply to comments on pull requests (PRs) directly from the command line. It streamlines GitHub workflows by enabling quick feedback without leaving the terminal.

Use it to post general comments on a PR, edit your previous comment, or provide inline feedback using diff hunk syntax. Specify a PR by number, URL, branch name, or omit for the current branch's PR. The comment body can be provided inline, via stdin, or from a file.

This command requires authentication via gh auth login. It's ideal for CI/CD pipelines, code reviews, and automating responses. Supports repository overrides for cross-repo operations.

Requires GitHub CLI authentication (gh auth login). Cannot edit others' comments. Inline file comments use special @@ syntax in body. No direct support for threading replies without review context.

Introduced in GitHub CLI v0.5.0 (Feb 2020). Enhanced with --edit-last in v1.0.0 (2021) and repo overrides in later releases. Actively maintained by GitHub.
