Use when making architectural decisions, planning features, designing new components, reviewing PRs, or validating that proposed changes align with Clean Architecture principles. Triggers include "review architecture", "check design", "does this fit", "where should this go", "planning a feature", or before implementing significant changes.

Cross-validate documentation and artifacts across the codebase for consistency, conflicts, and contradictions. Use when users ask to "cross-validate", "validate docs", "check documentation consistency", "audit documentation", or find conflicts/contradictions in docs. Supports automatic fixing with "validate and fix" argument. Runs parallel subagents for efficient validation across categories (domain-models, agent-system, tech-stack, architecture, cli-commands).

Use when the user wants rapid implementation iteration without tests, builds, or commits. Triggers include "fast loop", "fast iteration", "just code", "no tests", "iterate quickly", or when the user says they have a dev server running and want to check results manually.

Validate specs and autonomously execute implementation tasks with status tracking. Use after /shep-kit:plan when ready to start implementation.

Use after a PR has been merged to clean up. Switches to main, pulls latest, and deletes the local feature branch. Triggers include "merged", "pr merged", "cleanup branch", or after confirming a PR was merged.

Use when starting any new feature, functionality, or enhancement. Triggers include "new feature", "start developing", "add functionality", "implement X", or explicit /shep-kit:new-feature invocation. Creates spec branch and scaffolds specification directory.

Fast-track feature creation that collapses new-feature, research, and planning into a single autonomous pass. Produces all spec YAMLs (spec, research, plan, tasks, feature) in one go with minimal user interaction. Triggers include "quick feature", "fast feature", "rapid spec", or explicit /shep-kit:new-feature-fast invocation.

Use when a task can be worked on in isolation alongside other work. Creates a git worktree in .worktrees/ with a unique branch for parallel development. Triggers include "parallel task", "worktree", "work in isolation", or explicit /shep-kit:parallel-task invocation.

Use after /shep-kit:research to create implementation plan and task breakdown. Triggers include "plan", "implementation plan", "break down tasks", "create tasks", or explicit /shep-kit:plan invocation.

Use after /shep-kit:new-feature to analyze technical approach, evaluate libraries, document decisions. Triggers include "research", "technical analysis", "evaluate options", "which library", or explicit /shep-kit:research invocation.

Quick feature status and "what to do next" guide. Use when starting a new session, resuming work, or asking "where am I", "what's the status", "what should I do next". Gives a zero-to-hero walkthrough of the current feature branch.

Use when creating, modifying, or reviewing web UI components. Triggers include "new component", "add component", "create UI", "build a widget", "update component", working with files in src/presentation/web/components/, or when the user asks to build any React component for the web UI.

Use when creating, modifying, or documenting TypeSpec domain models. Triggers include adding new entities, value objects, enums, extending base types, or when asked to create a "tsp model", "domain model", "entity", or work with files in the tsp/ directory.
