How to use the running FinanceManager app as an agent — above all the develop-only auto test login (/DevelopLogin/{login}/{page}) that skips the landing page and login form. Use this skill whenever you need to sign in to the app for testing (UI or API), deep-link to an authenticated page, or obtain an access token without credentials. Covers guest vs testuser accounts, environment gating, and direct API usage.
Use this skill whenever a change touches the Blazor UI (any .razor/.razor.cs/.razor.css under FinanceManager.Components, layouts, or styling) and you need to see it rendered — not just compiled. It explains how to boot the app in the cloud sandbox, log in through the built-in guest/demo account, and screenshot the real pages on both mobile and desktop viewports using the pre-installed Playwright Chromium.
Use this skill whenever a code change introduces a user-visible difference (new feature, behaviour change, bug fix, removal, security patch). It explains how to add or update entries in the root `CHANGELOG.md` so the project keeps a consistent, human-readable history any agent can extend.
