Skill Claude CodeCodex
Use this skill when the user asks broad .NET questions or the project contains .sln/.csproj files and the exact ASP.NET/EF/C# subdomain is not yet clear. Detect the SDK/project shape, run or recommend .NET CLI commands, and route to Minimal APIs, Web API, MVC, Tag Helper, EF Core, or C# skills when appropriate.
Skill Claude CodeCodex
A guide for assessing a software project and building a complete, evidence-based engineering support system around it. This system can include project knowledge, plans, verification, and recovery information.
Skill Claude CodeCodex
Use this skill when you need to inspect a target project codebase and generate or improve a tailored, comprehensive AGENTS.md file (Harness Workflow Specification) that enforces strict AI agent harness rules, feedback sensors, execution SOP, orchestration topologies, and safety redlines. Supports non-interactive…
Skill Claude CodeCodex
Use this skill when the user needs to establish, review, or improve an ISO/IEC 27001 ISMS, perform information security risk discovery, define scope, create an evidence matrix, conduct a gap analysis, draft a Statement of Applicability, prepare for an internal audit, or create an improvement plan.
