Included Skills2

sdlc-orchestratorskills/sdlc-orchestrator/SKILL.md

Run or resume the complete evidence-driven software lifecycle after routing. Enforces deterministic state, progressive context, budgets, least privilege, verification gates, artifact handoffs, review, release/deploy/observe, incident and maintenance workflows.

sdlc-routerskills/sdlc-router/SKILL.md

Use automatically, before planning/editing/tool use, for any request that changes, investigates, operates on, or ships a real software repository or system - features, bug fixes, debugging, incidents, tests, review, security, dependency/platform upgrades, database migrations, CI/CD, release, deployment, observability, maintenance, modernization, documentation and compliance work. Routes to exactly one SDLC workflow and hands control to sdlc-orchestrator. Generic programming Q&A, tutorials and standalone examples do not activate it.
