Skill Claude CodeCodex
Writes an Architecture Decision Record (ADR) documenting a decision, its context, the options considered, and its consequences. Use to record a decision that's already been made so future readers understand why.
Skill Claude CodeCodex
Reviews application architecture for scalability, coupling, separation-of-concerns, and maintainability issues. Use for system-level review, not individual file/function-level code review.
Skill Claude CodeCodex
Designs multi-tier caching architectures (CDN, Redis, memory), invalidation policies, and stampede mitigations.
Skill Claude CodeCodex
Analyzes cloud infrastructure and architectures to identify wasted spend and right-sizing opportunities.
Skill Claude CodeCodex
Designs Command Query Responsibility Segregation (CQRS) and Event Sourcing models with projection rebuilders.
Skill Claude CodeCodex
Formulates RTO/RPO targets, cross-region failover, backup verification, and split-brain recovery procedures.
Skill Claude CodeCodex
Designs event-driven systems with CloudEvents schemas, message brokers, idempotency keys, and dead-letter queues.
Skill Claude CodeCodex
Establishes flag naming, fallback defaults, rollout rings, cleanup telemetry, and automated dead flag retirement.
Skill Claude CodeCodex
Plans a safe, incremental migration (framework, database, service, or platform) with rollback points and a dual-running strategy. Use when replacing something that's already in production and can't just be swapped in one step.
Skill Claude CodeCodex
Architects database multi-tenancy models (Shared DB/Schema vs Separate Schema vs Separate Database) and tenant routing.
Skill Claude CodeCodex
Converts an idea into a structured development plan with milestones, tasks, dependencies, and implementation phases. Use when an idea or feature needs to be broken into a plan before work starts.
Skill Claude CodeCodex
Designs distributed token bucket, leaky bucket, and tiered rate limiting architectures to prevent abuse.
Skill Claude CodeCodex
Inventories technical debt across a codebase and prioritizes it by cost-of-delay versus effort, producing a ranked paydown list. Use when debt is accumulating but it's unclear what to fix first.
Skill Claude CodeCodex
Plans blue-green rollouts, canary deployments, and expand-and-contract schema migrations with zero downtime.
Skill Claude CodeCodex
Helps design REST APIs - routes, request/response structures, validation, status codes, and conventions. Use when designing new endpoints or reviewing an existing API's design for consistency.
Skill Claude CodeCodex
Searches code specifically for potential bugs, edge cases, race conditions, and incorrect assumptions rather than general style/quality. Use when the goal is finding what's broken, not improving what already works.
Skill Claude CodeCodex
Reviews source code for bugs, readability, maintainability, performance, and best-practice violations. Use for general-purpose code review of a diff, file, or function, not tied to a specific language concern.
Skill Claude CodeCodex
Identifies race conditions, mutex contention, unsafe shared state, and deadlocks in concurrent and async code.
Skill Claude CodeCodex
Reviews database schemas, relationships, indexes, constraints, and data modeling decisions. Use when designing a new schema or reviewing an existing one for correctness and scalability.
Skill Claude CodeCodex
Reviews package dependencies for unnecessary packages, outdated or risky patterns, duplication, and licensing/maintenance risk. Use when a dependency manifest has grown unchecked or before adding a new dependency.
Skill Claude CodeCodex
Designs structured error hierarchies, domain error mapping, and resilient fallback/retry mechanisms across applications.
Skill Claude CodeCodex
Designs ergonomic, performant GraphQL schemas with Relay pagination, input validation, and N+1 prevention.
Skill Claude CodeCodex
Formulates safe Mikado Method refactoring dependency graphs and Strangler Fig extraction paths for fragile legacy codebases.
Skill Claude CodeCodex
Identifies unclosed handles, event listener accumulation, retain cycles, and heap memory leak patterns.
