Generate Code Review Slack Command

Command: cursor generate-code-review-slack-command

Overview

Generate a formatted, copiable Slack command for the #code-review channel with PR information, Jira ticket, test environment link, and optional component summaries (FE, BE, Python, TypeScript). Automatically extracts information from the GitHub PR for the current branch and outputs a command that can be copied, edited (to add @ mentions, media links, etc.), and pasted into Slack.

Execution model: Automatically extracts information from GitHub PR, prompts only for missing information, formats the message according to the template, and outputs a copiable Slack command (does NOT send automatically).

This workflow will:

Find the GitHub PR for the current branch
Extract Jira ticket from PR title
Extract test environment link from PR description
Extract component summaries (FE, BE, Python, TypeScript) from PR description
Prompt only for missing information
Allow user to customize the message slightly
Format the message according to the code review template
Generate a copiable Slack command that can be edited before sending
Display the command for easy copying

Inputs

Required Information (auto-extracted from PR, prompted if missing)

Jira ticket: Extracted from PR title (format: [OPIK-1234]) or prompted if not found
PR link: Automatically determined from current branch's PR or prompted if no PR found
Test env link: Extracted from PR description (Testing or Details section) or prompted if not found

Optional Information (auto-extracted from PR, prompted if missing)

FE summary: Extracted from PR description (looks for frontend/React/FE mentions) or prompted if not found
BE summary: Extracted from PR description (looks for backend/Java/BE mentions) or prompted if not found
Python summary: Extracted from PR description (looks for Python/Python SDK mentions) or prompted if not found
TypeScript summary: Extracted from PR description (looks for TypeScript/TypeScript SDK/TS mentions) or prompted if not found
Baz approved status: Extracted from PR status checks (optional, may not be available)

Configuration

No Slack MCP required: This command does not send messages, so Slack MCP configuration is not needed
GitHub MCP: Required for extracting PR information

Steps

1. Preflight & Environment Check

Check GitHub MCP: Test GitHub MCP availability by attempting to fetch repository info using get_file_contents for comet-ml/opik

If unavailable, respond with: "This command needs GitHub MCP configured. Set MCP config/env, run make cursor (Cursor) or make claude (Claude CLI), then retry."
Stop here.
Check Git repository: Verify we're in a Git repository
Check current branch: Get current branch name

2. Find GitHub PR for Current Branch

Search for PR: Use GitHub MCP to find an open PR for the current branch in comet-ml/opik
If PR found:
- Extract PR number, URL, title, and description
- Store PR information for extraction steps
If no PR found:

"No open PR found for this branch. Please provide the PR link manually:"
- Prompt for PR link and validate URL format
- If provided, fetch PR details using GitHub MCP
- If PR cannot be fetched, stop with error message
- After successfully fetching PR by manual link: Extract PR number, URL, title, and description and store PR information for extraction steps (same as "PR found" branch)

3. Extract Information from PR

Extract Jira ticket from PR title:
- Parse PR title for pattern [OPIK-\d+] or [issue-\d+] or [NA]
- Extract ticket number (e.g., OPIK-1234 from [OPIK-1234] [BE] feat(api): add trace request validation endpoint)
- If not found in title, check PR description "## Issues" section for OPIK-\d+ pattern
- If still not found, prompt: "Jira ticket not found in PR. Enter Jira ticket number (e.g., OPIK-1234):"
- Validate format and store
- Build Jira URL: Construct Jira link as https://comet-ml.atlassian.net/browse/{TICKET} (e.g., https://comet-ml.atlassian.net/browse/OPIK-1234)
Extract Baz approved status (optional):
- Try to fetch PR status checks using GitHub MCP
- Look for status checks or CI checks that might indicate "Baz approved" or similar approval status
- If found, store the status (e.g., "Baz approved: ✅" or "Baz status: pending")
- If not found or unavailable, skip this field (it's optional)
Extract test environment link from PR description and comments:
- First, search PR comments for test environment deployment messages (look for "Test environment is now available!" or similar)
- When fetching PR comments via gh api, always use --paginate to ensure all results are fetched:
  bash
```
# Issue comments (general PR comments, including deployment bot messages)
gh api repos/comet-ml/opik/issues/{pr_number}/comments --paginate

# Review comments (inline code comments)
gh api repos/comet-ml/opik/pulls/{pr_number}/comments --paginate
```
  Why pagination is required: GitHub API returns 30 items per page by default. Opik PRs regularly exceed this — 17 CI test group comments + deployment bot comments + reviewer comments can push past 30 total. Without --paginate, the deployment bot comment with the test environment link may end up on page 2 and get silently missed.
- Extract URL from comment body (typically in format https://pr-XXXX.dev.comet.com or https://test.opik.com)
- If not found in comments, search PR description for URLs in "## Testing" section
- Look for common test environment patterns: https://pr-*.dev.comet.com, https://test.opik.com, https://*.opik.com, or any https:// URL
- If multiple URLs found, prefer the first one that looks like a test environment
- If not found, search in "## Details" section for URLs
- If still not found, prompt: "Test environment link not found in PR. Enter test environment link (e.g., https://pr-4743.dev.comet.com):"
- Validate URL format and store
Extract component summaries from PR description:
- FE summary:
  - Look for mentions of "frontend", "FE", "React", "UI", or [FE] tag in PR description
  - Extract relevant one-line summary from "## Details" section or component-specific mentions
  - If not found, prompt: "Frontend summary not found in PR. Enter frontend summary (one line, optional - press Enter to skip):"
- BE summary:
  - Look for mentions of "backend", "BE", "Java", "API", or [BE] tag in PR description
  - Extract relevant one-line summary from "## Details" section or component-specific mentions
  - If not found, prompt: "Backend summary not found in PR. Enter backend summary (one line, optional - press Enter to skip):"
- Python summary:
  - Look for mentions of "Python", "Python SDK", "SDK", or Python-related changes in PR description
  - Extract relevant one-line summary from "## Details" section or component-specific mentions
  - If not found, prompt: "Python summary not found in PR. Enter Python summary (one line, optional - press Enter to skip):"
- TypeScript summary:
  - Look for mentions of "TypeScript", "TypeScript SDK", "TS", "TS SDK", or [TS] tag in PR description
  - Extract relevant one-line summary from "## Details" section or component-specific mentions
  - If not found, prompt: "TypeScript summary not found in PR. Enter TypeScript summary (one line, optional - press Enter to skip):"
Store extracted information: Keep all extracted and prompted values for message formatting

4. Prompt for Message Customization

Allow user to customize message: After extracting all information, prompt the user:

"Would you like to customize the message? (Enter any additional text to prepend/append, or press Enter to use default message):"
If user provides customization text: Store it for inclusion in the final message
If user presses Enter (empty): Proceed with default message format
Note: User can add context, emphasize certain points, or include additional information

5. Format Slack Message

Use PR link: Use the PR URL extracted from Step 2 (or provided manually)

Build message text according to the template:

Hi team,

Please review the following PR:

{{user_customization_text_if_provided}}

:jira_epic: jira link: {{Jira_URL}}
:github: pr link: {{PR_link}}

:react: fe summary (optional): {{description_in_one_line}}
:java: be summary (optional): {{description_in_one_line}}
:python: python summary (optional): {{description_in_one_line}}
:typescript: typescript summary (optional): {{description_in_one_line}}

Message structure:
- Start with greeting: Always begin with "Hi team,\n\nPlease review the following PR:\n"
- User customization: If user provided customization text in Step 4, include it after the greeting (before the structured fields)
- Jira link: Include full Jira URL with ticket (e.g., https://comet-ml.atlassian.net/browse/OPIK-1234)
- PR link: Include GitHub PR URL
- Test env link: Include test environment URL
- Baz approved status: Only include if extracted from PR status checks (optional field)
- Component summaries: Only include optional fields that were provided (skip empty ones)

Notes

GitHub MCP Required: Uses GitHub MCP to fetch PR information automatically
No Slack MCP Required: This command does not send messages, so Slack MCP configuration is not needed
Message format: Follows the exact template provided with emoji prefixes, includes greeting and Jira link
Automatic extraction: Extracts information from PR title and description to minimize manual input
Fallback to prompts: Only prompts for information that cannot be extracted from PR
Optional fields: Only included in message if extracted from PR or provided by user
Channel: Message is intended for #code-review channel
PR detection: Automatically finds PR for current branch, falls back to manual input if needed
Smart extraction: Uses heuristics to find test environment links and component summaries in PR description
Editing before sending: The generated command can be edited to add @ mentions, media links, video links, or make final proof edits before sending in Slack
Use case: This command is particularly useful when you want to:
- Add @ mentions for specific reviewers
- Include video links or media that Slack MCP cannot send directly
- Make final proof edits before sending
- Have more control over the final message format
Alternative for automatic sending: If you don't need manual editing, use cursor send-code-review-slack to send the message directly to Slack.
