What problem does it solve? Installing a new capability requires collecting personalized configuration (identity, timezone, preferences, secrets) in a structured, repeatable way. This Skill standardizes that interview process so answers land in a consistent MOD.md overlay without manual file editing or lost secrets. ## Core Features & Use Cases - Typed Interview Questions: Reads a capability's ONBOARDING.md frontmatter (string, number, boolean, enum, list, path types) and conducts a conversational, batched interview rather than a rigid form. - Secret Handling: Routes secret: true answers to the harness secret store, writing only {store, key} references into MOD.md so values are never persisted in plain text. - Diff-Gated Writes: Validates every answer against deterministic rules, shows a diff for approval before writing, and preserves unchanged answers byte-identically on re-runs. - Use Case: When installing a new personal-assistant capability, run the onboarding interview to capture your timezone, sacred hours, and API tokens, producing a versioned MOD.md that survives capability upgrades. ## Quick Start Ask your agent to run the onboarding interview for the capability you just installed and write the answers to your MOD.md overlay.
