Kieran Klaassen c06f7e889f feat(reproduce-bug): Add Playwright visual reproduction instructions

Enhanced /reproduce-bug command with browser automation:
- Added Phase 2 for visual bug reproduction using Playwright MCP
- Step-by-step guide for navigating to affected areas
- Screenshot capture at each reproduction step
- Console error checking
- User flow reproduction with clicks, typing, snapshots
- Better documentation structure with 4 clear phases

Reproduce Bug Command

Look at github issue #$ARGUMENTS and read the issue description and comments.

Phase 1: Log Investigation

Run the following agents in parallel to investigate the bug:

Task rails-console-explorer(issue_description)
Task appsignal-log-investigator(issue_description)

Think about the places it could go wrong looking at the codebase. Look for logging output we can look for.

Run the agents again to find any logs that could help us reproduce the bug.

Keep running these agents until you have a good idea of what is going on.

Phase 2: Visual Reproduction with Playwright

If the bug is UI-related or involves user flows, use Playwright to visually reproduce it:

Step 1: Verify Server is Running

mcp__plugin_compound-engineering_pw__browser_navigate({ url: "http://localhost:3000" })
mcp__plugin_compound-engineering_pw__browser_snapshot({})

If server not running, inform user to start bin/dev.

Step 2: Navigate to Affected Area

Based on the issue description, navigate to the relevant page:

mcp__plugin_compound-engineering_pw__browser_navigate({ url: "http://localhost:3000/[affected_route]" })
mcp__plugin_compound-engineering_pw__browser_snapshot({})

Step 3: Capture Screenshots

Take screenshots at each step of reproducing the bug:

mcp__plugin_compound-engineering_pw__browser_take_screenshot({ filename: "bug-[issue]-step-1.png" })

Step 4: Follow User Flow

Reproduce the exact steps from the issue:

Read the issue's reproduction steps
Execute each step using Playwright:
- browser_click for clicking elements
- browser_type for filling forms
- browser_snapshot to see the current state
- browser_take_screenshot to capture evidence

Check for console errors:

mcp__plugin_compound-engineering_pw__browser_console_messages({ level: "error" })

Step 5: Capture Bug State

When you reproduce the bug:

Take a screenshot of the bug state
Capture console errors
Document the exact steps that triggered it

mcp__plugin_compound-engineering_pw__browser_take_screenshot({ filename: "bug-[issue]-reproduced.png" })

Phase 3: Document Findings

Reference Collection:

Document all research findings with specific file paths (e.g., app/services/example_service.rb:42)
Include screenshots showing the bug reproduction
List console errors if any
Document the exact reproduction steps

Phase 4: Report Back

Add a comment to the issue with:

Findings - What you discovered about the cause
Reproduction Steps - Exact steps to reproduce (verified)
Screenshots - Visual evidence of the bug (upload captured screenshots)
Relevant Code - File paths and line numbers
Suggested Fix - If you have one
