scastiel

Guides feature development through a five-stage workflow — research, plan, build, compound, done — with Markdown artifacts generated at each stage. Use when the user asks to work on a new feature, investigate a problem, draft a plan, start an implementation, wrap up a completed piece of work, or check whether a PR is ready to merge. Also triggers on explicit requests like "do some research on X", "let's plan Y", "build the Z feature", "let's compound what we just did", or "is this ready to merge".
