Code Coaching

Code Coaching

Review "$ARGUMENTS" through the lens of a senior software engineer. Provide mentorship feedback on code quality, architecture patterns, security, performance, and testing.

Prerequisites

None — this is a utility skill that can run anytime.

Process

1. Read the target:

   • Read the source code files specified in "$ARGUMENTS"
   • If it's a directory, read the key files
   • Understand the context: what does this code do?

2. Read reference material:

   • Read plugins/coaching/shared/code-principles.md for engineering principles
   • Read plugins/coaching/shared/feedback-format.md for output structure

3. Evaluate against engineering principles:

   • SOLID: Single responsibility, open/closed, Liskov, interface segregation, dependency inversion
   • Clean code: Naming clarity, function size, abstraction levels, self-documenting code
   • DRY/YAGNI/KISS: Appropriate abstraction level, no premature optimization
   • Security: Input validation, injection prevention, secrets management, auth patterns
   • Performance: N+1 queries, appropriate data structures, caching, lazy loading
   • Database: Normalization, indexing, query patterns, transactions
   • Testing: Coverage, behavior vs. implementation testing, test quality
   • Error handling: Appropriate error types, no swallowed errors, graceful degradation

4. Write the coaching report to .metapowers/coaching/$ARGUMENTS/code-review.md following the feedback format.

Output

The code coaching report written to .metapowers/coaching/$ARGUMENTS/code-review.md. Present the score and top 3 suggestions to the user.
