run-parity
Compare React Doctor diagnostics for a GitHub pull request (PR) with Daytona. Use when asked to run parity, check a PR for diagnostic regressions, compare a PR with its base, or report added and removed diagnostics.
Profile →npx skills add millionco/react-doctor --skill run-parity --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Run pull request parity Run the pull request base and head against the same repository commits. Write deterministic newline-delimited JSON (NDJSON) artifacts and compare them. ## Prepare the run Require `DAYTONA_API_KEY`, authenticated `gh`, and a pushed pull request head. Do not push changes without permission. Use `ni` and `nr` in this repository. Resolve the pull request: ```sh gh pr view <pr-number-or-url> \ --json number,url,baseRefOid,headRefOid,headRepository,headRepositoryOwner ``` Derive the base repository from the pull request URL. Derive the head repository from `headRepositoryOwner.login` and `headRepository.name`. Use the returned commit hashes, not branch names. Create `tmp/parity-pr-<number>-<head-short-sha>` and preserve it after the run. Run `ni` before evaluation. ## Run both revisions Run from `packages/evals`. The default corpus contains the 2,000 highest-ranked repositories, and the initial concurrency is 200. Sandbox creation is capped at 20 to avoid overloading Daytona. The evaluator cleans up resources and retries failed projects at concurrency 50, then 10. ```sh nr --silent eval \ --react-doctor-repository <base-repository-url> \ --react-doctor-ref <base

What does the run-parity skill do?
Compare React Doctor diagnostics for a GitHub pull request (PR) with Daytona. Use when asked to run parity, check a PR for diagnostic regressions, compare a PR with its base, or report added and removed diagnostics.
How do I install it?
Run `npx skills add millionco/react-doctor --skill run-parity --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From millionco/react-doctor, a repository with 14,264 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
