Add pr-review external plugin to the marketplace

External Plugin Submission

Plugin

• Name: pr-review
• Repository: https://github.com/shinpr/pr-review-skill

What does this plugin do?

Reviews GitHub pull requests with Claude Code or Codex reviewers running on a deterministic PR snapshot (metadata, changed files, diff, prior comments, repository context). It produces structured, schema-validated findings, applies a repository-specific quality profile, and posts findings as GitHub comments only after showing a posting summary and asking for approval. Posting severities are configurable.

Why does it fit this marketplace's focus?

It sits in the verification / quality-enforcement part of the lifecycle. Reviews run against a repeatable snapshot, findings are validated against a JSON schema, posting is gated by configurable severities and an explicit approval step, and duplicate prevention runs at posting time. It complements rather than duplicates the existing plugins: the in-repo workflows review local implementation against design docs, whereas this reviews arbitrary GitHub PRs and returns/posts structured findings — a stage not otherwise covered here.

How have you tested it?

• The plugin repository ships a pytest suite covering config, context collection, review running, posting/guard, and metadata, and runs it in CI (GitHub Actions).
• For this submission I verified marketplace integration end to end: claude plugin validate passes on the plugin manifest, the plugin repo's marketplace manifest, and this marketplace's manifest. Loading this repo as a local marketplace and running claude plugin install pr-review@claude-code-workflows resolves the git-subdir source, sparse-fetches plugins/pr-review/, and loads the recipe-pr-review skill (SKILL.md + scripts present in the plugin cache).

Source resolution note

The plugin repo is itself structured as a marketplace (required for Codex plugin compatibility), with the plugin under plugins/pr-review/. It is therefore referenced via a git-subdir source with path: plugins/pr-review, rather than the plain url form used by the other external plugins.

pr-review is the same plugin name whether installed from this marketplace or the standalone pr-review-tools marketplace; install it from only one to avoid a name collision.
