Claude Skills by KbWen

Design or review REST/GraphQL APIs when endpoints or contracts change.

Secure authentication and authorization when credentials, sessions, roles, or permissions change.

Design schemas and migrations when persistent data structures change.

Evaluate when to dispatch parallel agents; use a 4-step pattern to split, coordinate, and integrate results.

Check official docs when framework APIs or configuration may be version-sensitive.

Apply frontend conventions when components, pages, forms, or client state change.

Behavioral guidelines to reduce common LLM coding mistakes — Think Before Coding, Simplicity First, Surgical Changes, Goal-Driven Execution.

Pre-ship observability readiness checklist — ensures errors reach production monitoring, not just debug consoles.

Adversarial security and resilience analysis — auto-triggered during /review and /test based on task classification. Provides attack surface analysis, boundary testing, auth bypass attempts, dependency chain attacks, and Beast Mode stress testing.

Decompose tasks via subagent collaboration; define interface contracts and integration checkpoints.

Use 4-phase root cause analysis (Observe, Hypothesize, Verify, Fix); avoid unverified patches.

Drive changes with Red→Green→Refactor; ensure behavior is verifiable and regression-safe.

Use Git worktrees to create parallel working directories safely; avoid branch-switch contamination.

Enforce "no evidence = no completion"; run Gate Function verification before declaring done.
