Branch Code Review

Review code changes on a feature branch, checking for:

• Pattern consistency with existing codebase
• Code duplication that should be factored out
• Unnecessary temporary variables
• Proper use of existing functions and utilities
• Potential N+1 query patterns or looped API calls
• Type safety issues (avoiding

  as any

  casts)
• Error handling consistency

Usage

/branch-review [base-branch]

Arguments:

• base-branch

  (optional): The branch to compare against. Defaults to

  master

  .

Review Process

Step 1: Gather Context

First, get an overview of the changes:

# Get summary of changed files
git diff [base-branch]...HEAD --stat

# Get the detailed diff
git diff [base-branch]...HEAD

Step 2: Read Changed Files

For each significantly changed file, read the full file to understand context:

• Use the

  Read

  tool to examine new/modified files
• Look at surrounding code to understand existing patterns
• Check imports and dependencies

Step 3: Pattern Analysis

Compare new code against existing patterns in the codebase:

1. Store Modules: Check if new store modules follow

   vuex-module-decorators

   patterns
2. API Clients: Verify API methods follow existing error handling patterns
3. Vue Components: Ensure components follow existing structure (props, computed, methods order)
4. Backend Models: Check Girder plugin patterns (ProxiedModel, @autoDescribeRoute, etc.)

Step 4: Issue Categories

Organize findings into categories:

as any

Step 5: Provide Actionable Feedback

For each issue:

1. Quote the specific code location (

   file:line

   )
2. Explain why it's an issue
3. Provide a concrete suggestion or code example
4. Note the severity (must fix vs. nice to have)

Summary Table

## Codebase-Specific Guidelines

When reviewing this codebase, pay special attention to:

1. **Batch API Calls**: Never loop and make individual API calls. Use batch endpoints.
2. **Store vs API Error Handling**: Errors should be caught in store actions, not API methods.
3. **TypeScript Types**: Avoid `as any`. Extend interfaces if needed.
4. **Vue Patterns**: Use `vuex-module-decorators` style (@Module, @Action, @Mutation).
5. **Utility Functions**: Check `src/utils/` before creating new helpers.
