Review Blade PR

Review PRs in the razorpay/blade repository by fetching the diff, checking CI status, and extracting the Storybook preview URL.

Arguments / Clarifications (Use Cursor's AskQuestion tool to get clarifications)

• PR: Link / Number of the PR to review
• ShouldReviewUI: Whether UI should be reviewed or not. Get it clarified if not mentioned.
• ShouldRunHeadedBrowser: Whether to run the browser in headed mode or not. Get it clarified if not mentioned.

Prerequisites

• GitHub CLI (gh) must be installed and authenticated
• agent-browser command must be installed (if ShouldReviewUI is true)

Guidelines

• Avoid printing intermediate commentary; only output the final review in the main chat

Steps (Create checklist for each step)

1. Fetch the PR Diff and CI Status in Main Agent

https://patch-diff.githubusercontent.com/raw/razorpay/blade/pull/{PR_NUMBER}.diff

(Ignore the lock file changes from diff)

Fetch status checks once and extract both CI status and Storybook URL:

gh pr checks {PR_NUMBER} --repo razorpay/blade

If checks are failing / skipped, get the details from the checks on why they are failing / skipped

Use the following command (replace {JOB_ID} with the job id from the previous gh pr checks output):

gh run view --job {JOB_ID} --repo razorpay/blade

2. UI Review the Changes (if ShouldReviewUI is true)

• Using agent-browser (Do NOT use Playwright MCP), open the Storybook URL (returned by earlier subagent)
  • agent-browser --help on docs on how to use it
• Determine which URL to open based on the PR changes
• agent-browser close to close any earlier opened browser instances
• Open the URL with the agent-browser and test the functionality of the changes

  agent-browser open {storybook_url} --headed (if ShouldRunHeadedBrowser is true)
  

• Close the agent-browser at the end with agent-browser close

How to Find Changes

• You can open the story outside iframe using the iframe.html url of storybook
  • E.g. https://61c19ee8d3d282003ac1d81c-rzqbxanzgn.chromatic.com/?path=/story/components-datepicker--date-picker-presets-with-display-format-compact this story can be opened as an iframe in https://61c19ee8d3d282003ac1d81c-rzqbxanzgn.chromatic.com/iframe.html?args=&id=components-datepicker--date-picker-presets-with-display-format-compact&viewMode=story
  • If iframe is not working, open the storybook url directly and find the story in the sidebar
• If changes are in svelte components, check the svelte version of storybook on {storybook_base_url}/svelte/ route

Report the flows / features that were tested, if they are working as expected or not, and the issues found.

3. Code Review the Changes

Analyze the diff for:

• Potential bugs or logic errors
• TypeScript/type safety issues
• Missing tests for new functionality
• Accessibility concerns
• Performance implications
• API Breaking changes
• Do not review the changes in the codebase, only review the changes in the diff.

Output Format

The subagent should return all the gathered information. Then in the main chat strictly following the output format mentioned in references/output-format.md
