Core Dev is a production-ready Claude Code skill (quality score 70/100) in the architecture sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/core-dev/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when working with workflow execution (orchestrators, processors), node tree navigation (Node, NodePosition), task states (TaskState, WorkflowCommand, WorkflowEvent), expression evaluation (JQ, scope), error handling (TryTask, retry, catch), parallel execution (Fork), or DSL parsing. Covers the step-by-step execution model, exception-driven control flow, and stateless architecture.
The Core Dev skill is built for software engineers, backend developers, full-stack teams, and technical leads building and maintaining production systems. It is part of the open ClaudSkills registry, a community-curated catalog of 15,000+ capabilities you can install for Claude Code — the Claude CLI agent.
