What problem does it solve? Writing end-user manuals from source code produces inaccurate, screenshot-free documents that drift from the real product. This Skill generates operation manuals grounded in actual UI behavior by running the system for real, walking each feature, and capturing every screen. ## Core Features & Use Cases - Operation-based authoring: Starts the local E2E environment, logs in as a seeded test user, and performs every documented step through the UI so the manual reflects real behavior. - Structured HTML output: Produces one HTML page per feature with numbered steps and screenshots, plus a required table-of-contents page, all styled by a shared self-contained stylesheet. - Version-bound output: Writes each manual set under docs/manuals/v<version>/ tied to the repository's package.json version, preserving old versions as immutable history. - Use Case: After releasing version 0.3.0 of a web app, invoke this Skill to walk the login, registration, and admin features in the E2E stack and publish a complete Japanese-language user manual with screenshots under docs/manuals/v0.3.0/. ## Quick Start Generate the end-user operation manual for the current product version by walking every feature in the running E2E environment and writing the HTML pages with screenshots.
