Audit M3UAndroid Room schema and migration changes for versioning, schema artifacts, data preservation, indices, defaults, DAO compatibility, and migration validation.

Audit M3UAndroid playback flows for UI/engine/persistence boundaries, lifecycle cleanup, Media3 integration, casting, overlays, resume/autoplay behavior, and TV control risks.

Audit M3UAndroid M3U and EPG data flows for parser behavior, channel/programme matching, duplicate handling, fallback behavior, joins, and timezone/time-range correctness.

Audit Android Jetpack Compose repositories for performance, state management, side effects, and composable API quality. Scans source code, scores each category from 0-10, writes a strict markdown report, and summarizes the most important fixes. Use when reviewing a Compose codebase, rating repository quality, inspecting recomposition/state issues, or running a Compose audit.

Audit M3UAndroid localization resources for missing default strings, placeholder consistency, key naming, hardcoded user text, fallback behavior, and locale safety.

Audit M3UAndroid extension APIs and runtime for host/plugin boundaries, classloader compatibility, manifest metadata assumptions, IPC/protobuf compatibility, and dependency leakage.

Audit M3UAndroid APK/AAB size and packaging changes for dependency growth, native libraries, resources, R8/minification, generated assets, baseline profiles, and artifact comparison evidence.

Audit M3UAndroid Android TV screens for DPad focusability, focus order, initial focus, visual focus states, touch assumptions, and couch-distance readability. Use when reviewing TV UI or changing focus behavior.

Perform an unusually strict code-quality audit focused on structural simplification, maintainability, abstraction quality, file growth, branching complexity, type boundaries, architectural ownership, and test quality. Use for thermonuclear reviews, deep maintainability audits, harsh code-quality reviews, or reviews that should seek ambitious behavior-preserving restructuring rather than local cleanup.

Operate recurring Bangle.io agent follow-ups after a thread has already started. Use when the user asks to continue, check status, decide what is next, push, create or update a PR, poll CI, rebase, merge, release, run Playwright/manual UX checks, spawn or aggregate code-review subagents, run thermonuclear review, address review findings, make a plan, add a project task, or asks "we good?", "pushed?", "PR?", "did you test?", "what should I test?", or similar follow-up prompts in the Bangle repo.

Build, test, package, and release the Bangle.io Electron desktop app. Use when working on desktop nightlies, stable desktop releases, Electron smoke tests, updater artifacts, or macOS signing/notarization.

Write idiomatic Wordgard editor code (schema elements, extensions, commands, decorations, markdown specs) for the editor-w stack. Use whenever working on wordgard, @bangle.io/wordgard-utils, @bangle.io/wordgard-markdown, or packages/core/editor-w, or when reviewing such code.
