Included Skills6

debug-failuresskills/debug-failures/SKILL.md

Diagnose Biloba failures in TypeScript/Vitest — BilobaError codes and fields, polling trajectories, DOM outlines, screenshots and visual artifacts, context-wide session.captureDiagnostics(), console/warning streams, debug logs, Vitest hooks, and renderer/browser/daemon crash distinctions. Use when a Biloba Vitest test fails, hangs, flakes, or needs CI/agent artifact configuration.

flaky-testsskills/flaky-tests/SKILL.md

Diagnose and prevent flaky Biloba TypeScript/Vitest tests — redundant client-side retry loops, immediate mode, single-shot evaluate reads, optimistic UI, async layout, first-match-wins network handlers, held responses, vacuous assertions, visual update/tolerance hazards, and lifecycle leakage. Use when a Biloba Vitest test is intermittent, order-dependent, load-sensitive, or only fails in CI/parallel workers.

overviewskills/overview/SKILL.md

Explain Biloba's TypeScript/Vitest mental model — one shared Chrome, one bilobad process per Vitest worker, isolated reusable root sessions, server-side polling, fast versus realistic input, and structured diagnostics. Use first when adopting biloba or deciding how to structure a Vitest browser suite. Route to the other biloba-vitest:* skills.

setupskills/setup/SKILL.md

Wire Biloba's TypeScript client into Vitest — install biloba and its platform package, install chrome-headless-shell, start one shared Chrome in global setup, provide its connection to workers, create one daemon and reusable root Session per test file, prepare between tests, close cleanly, and choose launch modes/options. Use when installing biloba or changing suite-level browser/daemon lifecycle.

visual-assertionsskills/visual-assertions/SKILL.md

Create and maintain Biloba screenshot assertions in TypeScript/Vitest — page and locator captures, committed baselines, update mode, masks, pixel and channel tolerances, animation freezing, light/dark schemes, diff artifacts, and structured visual diagnosis. Use when adding expectScreenshot(), reviewing baselines, or diagnosing a visual mismatch.

write-testsskills/write-tests/SKILL.md

Author Biloba browser tests in TypeScript/Vitest — sessions, tabs, frames, CSS/semantic/XPath locators, polling actions and assertions, realistic input, cookies/storage, dialogs/downloads/network, screenshots, and structured failures. Use when writing or reviewing tests against biloba. For wiring the daemon and shared Chrome, use biloba-vitest:setup.
