fantasia

Execute a plan with parallel specialist agents - architect designs, implementer builds, integrator connects

Save current Fantasia workflow state as a checkpoint for later resumption

Check CI/CD pipeline status for current branch

Provide feedback that a fix isn't working as expected, enabling iterative refinement

Investigate and fix a bug, optionally from a Sentry issue

Explores a specific implementation approach for a feature, proposing design with trade-offs

Analyzes system architecture and code organization. Used by /fantasia:map to document ARCHITECTURE.md and STRUCTURE.md. <example> User runs /fantasia:map and the orchestrator needs to understand the system architecture. Assistant spawns arch-mapper to analyze directory structure, entry points, and component relationships. </example> <example> User runs /fantasia:map auth to focus on authentication architecture. Assistant spawns arch-mapper with instructions to pay special attention to auth-related components and data flow. </example>

Designs system architecture, creates interfaces and contracts. Used by /fantasia:build for design decisions before implementation. <example> User runs /fantasia:build and the plan includes designing new types and interfaces. Assistant spawns architect to create type definitions and API contracts before implementer starts. </example> <example> A feature requires defining how components will communicate. Assistant spawns architect to design the interfaces and data contracts first. </example>

Hunts for bugs, edge cases, and potential runtime errors. Used by /fantasia:review to find issues before they hit production. <example> User runs /fantasia:review after completing a build. Assistant spawns bug-hunter to search for logic errors, unhandled edge cases, and security issues. </example> <example> User is concerned about potential bugs in new code. Assistant spawns bug-hunter to analyze code paths for null checks, error handling, and boundary conditions. </example>

Investigates bugs by tracing code paths, identifying root causes, and assessing impact

Use when building features in a codebase that has Fantasia maps (~/.claude/fantasia/<project>/codebase/). This skill teaches how to read and apply mapped patterns when writing new code.
