Legacy Ibmi Flow Analyzer
Analyze a complete IBM i call chain — one business transaction end-to-end across all programs it touches. Supports seven trigger models (batch job, interactive menu, subfile dispatch, F-key branch, DB trigger, scheduler, API/remote). Produces a flow analysis covering trigger context, sequence, cross-program data flow, error propagation, commit boundaries, UI surfaces, and business-capability seeds. Use when a single program analysis is insufficient because the business event spans multiple programs. Layer 1.5 (platform-specific) skill of the Legacy Spec Factory reverse chain.
Legacy Modernization Orchestrator
Entry-point router for the Legacy Spec Factory reverse chain. Use for natural-language guidance through IBM i / AS400 / RPGLE / CLLE / COBOL modernization, including document/spec/RAG/context intake, inventory, program and flow analysis, module analysis, legacy BRD discovery, post-BRD old-vs-new disposition, spec writing, and SDLC handoff. Routes users to the safest next skill and does not replace downstream extraction, synthesis, review, risk-assessment, or gap-analysis processes.
Legacy Spec Writer
Produce evidence-backed spec.yaml and spec.md artifacts from approved module + flow + program analyses plus an approved legacy-system BRD Package after stakeholders explicitly promote a capability beyond legacy discovery. One spec per business capability (CAP-). Layer 2 (platform-agnostic) skill — sits after BRD review and any separate post-BRD comparison / gap-analysis decision, producing the contract that downstream SDLC can consume. Implements schemas/spec.schema.yaml.
