This migration-planning skill is not malicious, but it deserves review because its workflow can move from planning into GitHub issue creation and orchestrated execution without a clearly separate execution confirmation.
Install only if you are comfortable with this skill reading a full legacy repository, writing migration artifacts into the target repo, checking GitHub CLI auth, and, after approval, creating GitHub issues. Before using the delivery phases, confirm that the downstream write-specs, create-issues, and orchestrator skills are trusted, and require a separate explicit confirmation before any orchestrator execution, especially because the artifact says it may execute all approved SPECs including pre-existing ones. Also adjust or avoid the skill if Portuguese-only prompts would make approvals unclear.
