Skill Claude CodeCodex
When a user instruction is vague, open-ended, or could be interpreted in multiple ways, do NOT guess and proceed. Proactively analyze the instruction and present all possible interpretations for the user to confirm before taking action.

Before mainnet deployment, verify all items.
Skill Claude CodeCodex
Skill "git-workflow" from ComeOnOliver/skillshub, covering git collaboration standards, language rule, commit rules, commit workflow and branch naming.
Skill Claude CodeCodex
Security audit and code review checklist. Covers 30+ vulnerability types with real-world exploit cases (2021-2026) and EVMbench Code4rena patterns. Use when conducting security audits, code reviews, or pre-deployment security assessments.
Skill Claude CodeCodex
When an event represents a conditional/branching outcome (the same action can happen for different reasons), add a string reason parameter to make on-chain data self-documenting.
Skill Claude CodeCodex
A troubleshooting workflow for failed Ethereum smart-contract transactions using Foundry’s command-line tools. It checks transaction receipts and details, then helps identify whether the failure involved gas, a revert, or another cause.
Skill Claude CodeCodex
Skill "solidity-deploy" from ComeOnOliver/skillshub, covering deployment workflow, language rule, pre-deployment checklist (all must pass), deployment decision rules and post-deployment operations (all required).
Skill Claude CodeCodex
When writing or reviewing Solidity code, apply these rules.
Skill Claude CodeCodex
Every core function must have tests covering.
Skill Claude CodeCodex
Configure Akka.NET with .NET Aspire for local development and production deployments. Covers actor system setup, clustering, persistence, Akka.Management integration, and Aspire orchestration patterns.
Skill Claude CodeCodex
Critical Akka.NET best practices including EventStream vs DistributedPubSub, supervision strategies, error handling, Props vs DependencyResolver, work distribution patterns, and cluster/local mode abstractions for testability.
Skill Claude CodeCodex
Patterns for building entity actors with Akka.Hosting - GenericChildPerEntityParent, message extractors, cluster sharding abstraction, akka-reminders, and ITimeProvider. Supports both local testing and clustered production modes.
Skill Claude CodeCodex
Akka.Management for cluster bootstrapping, service discovery (Kubernetes, Azure, Config), health checks, and dynamic cluster formation without static seed nodes.
Skill Claude CodeCodex
Write unit and integration tests for Akka.NET actors using modern Akka.Hosting.TestKit patterns. Covers dependency injection, TestProbes, persistence testing, and actor interaction verification. Includes guidance on when to use traditional TestKit.
Skill Claude CodeCodex
Configure Aspire AppHost to emit explicit app config via environment variables; keep app code free of Aspire clients and service discovery.
Skill Claude CodeCodex
Write integration tests using .NET Aspire's testing facilities with xUnit. Covers test fixtures, distributed application setup, endpoint discovery, and patterns for testing ASP.NET Core apps with real dependencies.
Skill Claude CodeCodex
Test email sending locally using Mailpit with .NET Aspire. Captures all outgoing emails without sending them. View rendered HTML, inspect headers, and verify delivery in integration tests.
Skill Claude CodeCodex
Create a shared ServiceDefaults project for Aspire applications. Centralizes OpenTelemetry, health checks, resilience, and service discovery configuration across all services.
Skill Claude CodeCodex
Analyze code coverage and CRAP (Change Risk Anti-Patterns) scores to identify high-risk code. Use OpenCover format with ReportGenerator for Risk Hotspots showing cyclomatic complexity and untested code paths.
Skill Claude CodeCodex
Design stable, compatible public APIs using extend-only design principles. Manage API compatibility, wire compatibility, and versioning for NuGet packages and distributed systems.
Skill Claude CodeCodex
Write modern, high-performance C# code using records, pattern matching, value objects, async/await, Span /Memory , and best-practice API design patterns. Emphasizes functional-style programming with C# 12+ features.
Skill Claude CodeCodex
Choosing the right concurrency abstraction in .NET - from async/await for I/O to Channels for producer/consumer to Akka.NET for stateful entity management. Avoid locks and manual synchronization unless absolutely necessary.
Skill Claude CodeCodex
Design .NET types for performance. Seal classes, use readonly structs, prefer static pure functions, avoid premature enumeration, and choose the right collection types.
Skill Claude CodeCodex
Database access patterns for performance. Separate read/write models, avoid N+1 queries, use AsNoTracking, apply row limits, and never do application-side joins. Works with EF Core and Dapper.
