Duo skills: symmetric Claude+Codex convergence (design, discuss, forge, prod-ready, research, review, testplan). Solo skills (Claude-only, explicit `solo` keyword): solo-testplan authors an e2e test plan tree; solo-runtestplan executes one or more test plan trees against a generated no-external-ports docker stack with append-only Bugs.md / Log.md ledgers and autonomous infra+observation recovery. linked-testplan is the shared rulebook for both testplan skills. scripts/check-refs.py validates flow-page references for solo-testplan / duo-testplan.
