▌
Beads · matthiasn bundle
Use for authorized Lotti maintainer work that needs private durable task tracking, issue dependencies, blocker management, multi-session handoff, or shared agent memory. Public contributors use GitHub Issues instead.

0
installs
▌
Release · matthiasn
Cut a Lotti release — assemble the changelog.d/ fragments into CHANGELOG.md and the Flathub metainfo, bump the version, open the release PR, then tag. Use when asked to cut or prepare a release, assemble the changelog, publish a new version, or work out what is unreleased.

▌
Analyze DB Logs · matthiasn
Analyze Drift / SQLite slow-query and super-slow-query logs against this app's known stall patterns (read waves, N+1, transaction scoping, MultiExecutor contention, WAL/OS factors)

0
installs
▌
App Screenshots · matthiasn
Capture in-app screenshots of a widget or flow at mobile + desktop sizes — offline, deterministic, real fonts and icons — using the reusable screenshot harness. Use when asked to "show me X in the app", "screenshot this screen", or to preview a UI change for review on phone vs desktop.

▌
Review Comments · matthiasn
Fetch PR review comments, address each one in code, and post resolution replies

0
installs
▌
Tutorial Videos · matthiasn
Build, debug, extend, localize, or publish the automated tutorial videos — the workbench that drives the real Linux app under Xvfb (virtual mic, live Voxtral transcription, task-agent proposals), records the screen, narrates with Gemini TTS, fast-forwards waits, composes MP4s via OpenMontage, and uploads finished videos to Cloudflare R2 for docs-site embedding. Use when asked to "build/regenerate the tutorial video(s)", add a tutorial scenario, add a tutorial locale, fix a broken tutorial run, adapt the pipeline, or upload/publish a video.

▌
Skeptical Review · matthiasn
Act as a skeptical senior engineer performing a detailed code review of the latest changes on the current branch (or a given PR) — best practices, maintainability, performance, security, and readability. Objective and concise; only real issues, with a clear "no issues" verdict when the code is clean. Replaces CodeRabbit / Gemini Code Review.

installs
▌
Design Review Panel · matthiasn bundle
Run a multi-agent design review on a UI surface — capture reproducible baseline screenshots, then rate them with a panel of design experts (one agent per craft dimension) and, optionally, a panel of user personas with different cognitive styles. Iterate implement → re-screenshot → re-rate until every panel hits a numeric target (e.g. avg ≥8/10). Use when polishing or redesigning a screen/modal/dialog and the user wants grounded, scored design feedback ("summon the design panel", "rate this with the experts", "run the persona panel").

installs
▌
Maintain Docusaurus Manual · matthiasn bundle
Maintain a Docusaurus product manual whose prose, navigation, localized page trees, screenshots, coverage metadata, and release build must stay aligned with the application. Use when adding or revising manual pages, documenting a product change, updating translated MDX, repairing locale parity, adding registered screenshots, auditing stale documentation, or validating a multilingual Docusaurus site before publication.

installs
▌
Add Flutter Docusaurus Locale · matthiasn bundle
Add, complete, or audit a locale across a Flutter application's ARB catalogs and a localized Docusaurus manual, including generated localization code, locale selectors, native platform declarations, translated MDX, screenshot fixtures, tests, and parity validation. Use when introducing a new language, finishing an incomplete app or manual translation, aligning manual terminology with UI strings, or reviewing whether a locale is production-ready end to end.

▌
Dance Lipsync · matthiasn
Generate real mouth-shape lip-sync cues for the character dance demo from a song's vocal stem, using Rhubarb Lip Sync via tools/dance_audio/lipsync.py. Use when the user wants believable lip movement (not one-vowel-per-word), to "lip sync the cats", produce a mouth-cue track, build/run Rhubarb, or improve how the singers' mouths follow the vocals.

0
installs
▌
Dance Track Prep · matthiasn
Prepare any song for the beat-synced character dance demo — produce its beat/downbeat map and word-timestamped lyrics (optionally lyric-forced-aligned with lead/background tags), using the offline tools in tools/dance_audio. Use when the user wants to "add a song", "prepare a track for the dance", sync the dancers to new music, generate a beat map or captions for a track, or align lyrics to audio.

0
installs
▌
Dance Pr Evidence · matthiasn
Standard for how character-animation PRs present visual evidence: before/after render grids, true-speed GIFs, movement-curve comparisons, and panel scorecards embedded directly in the PR body/comments. Use whenever opening or commenting on a PR that touches a dance clip, a rendering pass, the blend/transition machinery, or any shared runtime mechanism affecting the rig.

0
installs
▌
Character Video Export · matthiasn
Export the beat-synced character dance showcase to a verified MP4 with synced AAC audio using the repo's realtime Xwayland exporter, release-app exact-frame exporter, or Flutter-test fallback and ffmpeg. Use when the user wants a 1920x1080 or 1280x720 video for YouTube/Apple playback, a command-line render, an audio-synced capture, or one MP4 file instead of a live-app screen recording.

▌
Cinematic Render Panel · matthiasn
Score a rendered ART frame (a painted scene, character render, lighting look — NOT a UI surface) with a panel of cinematography/craft experts, grounded on a scratch render of the REAL production paint path. Iterate paint-code → re-render → re-score until a numeric target (e.g. 9/10). Use when polishing rendered visuals — "rate this scene with a cinematography panel", "is this render 9/10", "summon the cinematography panel", "judge the lighting/backdrop", "make the cats/yacht look cinematic". For UI/design-system surfaces use design-review-panel instead.

▌
Dance Render Artifacts · matthiasn
Generate the review artifacts for character animation: contact-sheet grids, per-frame sequences, true-speed animated GIFs, motion-trace (movement-curve) sheets, onion skins, transition strips, and before/after comparisons. Use whenever renders, GIFs, curves, or strips are needed for a panel, a PR, or an owner review.

▌
Scenery Art Layer Prep · matthiasn bundle
Prepare generated or hand-painted scenery art for layered Flutter backdrops: full-frame PNG plates, alpha masks, cloud/wave isolation, OpenCV cleanup, runtime stacking, parallax validation, and visual QA. Use when Codex needs to split a base backdrop into aligned layers, refine masks, make clouds/water independently movable, debug drifting building pixels, or document the asset-prep side of a scenery change.

0
installs
▌
Choreo Phrase Authoring · matthiasn bundle
Author, restructure, or improve beat-addressed character dance choreography as reusable phrase/move data. Use when Codex needs to add Afrobeats moves, map choreography to beat/downbeat analysis, reduce robotic sync, add per-cat style variance, improve pocket/groove, label dance sections, or stop random key tweaking in favor of extensible DancePhrase/AfrobeatsMove data.

installs
▌
Temporal Animation Diff · matthiasn
Analyze an animation frame-by-frame with golden-test-style temporal diffs. Use when motion looks jumpy, snappy, discontinuous, robotic, wobbly, or when a user asks to inspect animation "frame by frame", find "big diffs", "temporal diffs", "snaps", "jumps", or "where the animation changes too much between frames".

0
installs
▌
Flutter Shader Validation · matthiasn bundle
Diagnose and verify Flutter runtime-effect shader changes, including Impeller RuntimeStage/GLES compile errors, FragmentProgram asset loading, shader-vs-fallback rendering, and GLSL linter questions. Use when editing shaders/*.frag, seeing impellerc failures, adding scenery shaders, or deciding whether glslang/glslc can catch a shader bug.

0
installs
▌
Scenery Layer Registration · matthiasn bundle
Verify, regenerate, and debug full-frame scenery masks and alpha layers against a single master plate. Use when derived backdrop layers, masks, moving clouds, aircraft, drones, reflections, or other animated scenery appear shifted, clipped, ghosted, deregistered, or incorrectly occluded; use before claiming visual fixes to layer alignment.

0
installs
▌
Character Motion Review Panel · matthiasn bundle
Run a grounded expert panel on character animation using real rendered frame strips, dense frame captures, or video stills. Use when motion looks robotic, lame, snappy, wobbly, drunk, physically impossible, off-beat, weakly choreographed, or when the user asks to convene a dance coach, animator, MoCap/biomechanics, cartoon animation, cinematography, or music-video expert panel for the cat dance/walk/kick.
