What problem does it solve? Setting up a new AIS-OS (AI Operating System) project by hand is error-prone: files get missed, content drifts from the canonical baseline, and there is no proof the result matches the intended structure. This Skill scaffolds the exact frozen starter-kit tree into an empty directory and cryptographically verifies every file against a SHA-256 manifest before reporting success. ## Core Features & Use Cases - Deterministic scaffolding: Copies the bundled templates (CLAUDE.md, README.md, aios-intake.md, connections.md, decisions log, 3Ms framework reference, and the onboard/audit/level-up skills) byte-for-byte into the current working directory. - Cryptographic verification: Preflight-validates every bundled template against manifest.json using CRLF/CR-normalized SHA-256 hashes, then re-verifies the written tree and scans for unexpected paths. - Safe failure handling: Refuses to run in a non-empty directory (tolerating only pre-existing AIS-OS skill folders) and rolls back only the paths it created if any write or verification step fails. - Use Case: You want to start a fresh personal AIOS project. Open an empty folder in Claude Code, invoke the skill, and receive a verified baseline with a clear report of what was created and preserved. ## Quick Start Open an empty folder in Claude Code and type /aios-structure-build to scaffold and verify the AIS-OS starter-kit baseline.
