Root Cause Analysis: GitHub Issue #$ARGUMENTS

Objective

Investigate GitHub issue #$ARGUMENTS from this repository, identify the root cause, and document findings for future implementation.

Prerequisites:

• Working in a local Git repository with GitHub origin
• GitHub CLI installed and authenticated (gh auth status)
• Valid GitHub issue ID from this repository

Investigation Process

1. Fetch GitHub Issue Details

Use GitHub CLI to retrieve issue information:

gh issue view $ARGUMENTS

This fetches:

• Issue title and description
• Reporter and creation date
• Labels and status
• Comments and discussion

2. Search Codebase

Identify relevant code:

• Search for components mentioned in issue
• Find related functions, classes, or modules
• Check similar implementations
• Look for patterns or recent changes

Use grep/search to find:

• Error messages from issue
• Related function names
• Component identifiers

3. Review Recent History

Check recent changes to affected areas: !git log --oneline -20 -- [relevant-paths]

Look for:

• Recent modifications to affected code
• Related bug fixes
• Refactorings that might have introduced the issue

4. Investigate Root Cause

Analyze the code to determine:

• What is the actual bug or issue?
• Why is it happening?
• What was the original intent?
• Is this a logic error, edge case, or missing validation?
• Are there related issues or symptoms?

Consider:

• Input validation failures
• Edge cases not handled
• Race conditions or timing issues
• Incorrect assumptions
• Missing error handling
• Integration issues between components

5. Assess Impact

Determine:

• How widespread is this issue?
• What features are affected?
• Are there workarounds?
• What is the severity?
• Could this cause data corruption or security issues?

6. Propose Fix Approach

Design the solution:

• What needs to be changed?
• Which files will be modified?
• What is the fix strategy?
• Are there alternative approaches?
• What testing is needed?
• Are there any risks or side effects?
