What problem does it solve? Archflow projects depend on external tooling (git, node, codemap) and a consistent .archflow/ state directory, and silent drift between a project and the installed plugin causes confusing failures. This Skill runs a structured health check that identifies what is missing, what is degraded, and exactly how to fix it. ## Core Features & Use Cases - Environment and tooling checks: Verifies git, node, python3/PyYAML, codemap, and end-to-end test tooling, classifying each as PASS, WARN, or FAIL with the concrete cost of leaving it unfixed. - Project state validation: Inspects .archflow/ files such as current-phase.yaml, project-settings.yaml, and roadmap.yaml, with optional --validate schema validation and --fix repairs for upgrade drift, settings splits, and stack detection. - Use Case: A user reports that agents stopped working after a plugin update. Run the doctor to discover the project's framework files are behind the installed plugin, then apply --fix to refresh them with backups. ## Quick Start Ask the agent to run /archflow-doctor to check the environment and project state, optionally adding --validate or --fix.
