• animated-loop

  Generate a short seamlessly-looping video clip — splash background, animated logo backdrop, idle title-screen footage — wired as a looping VideoStreamPlayer.

  library/skills/animated-loop/SKILL.md on GitHub (opens in a new tab)

• animation-tree

  Design and wire AnimationTree state machines and blend trees so clips respond to gameplay — locomotion blends, attack interrupts, hit reactions.

  library/skills/animation-tree/SKILL.md on GitHub (opens in a new tab)

• art-direction

  Define the game's visual style — references, palette, mood, lighting plan, post-processing, do/don't list — output as an art bible at .summer/art-bible.md.

  library/skills/art-direction/SKILL.md on GitHub (opens in a new tab)

• asset-strategy

  Route any 'I need a [thing]' asset request to the right specialist skill — disambiguates 2D / 3D / audio / video / VFX / animation pipelines.

• audio-direction

  Define the game's sonic identity — music style, instruments, SFX vocabulary, dynamic music plan — output as an audio bible at .summer/audio-bible.md.

  library/skills/audio-direction/SKILL.md on GitHub (opens in a new tab)

• auto-fire-targeting

  Design or fix auto-fire weapon targeting (survivors, top-down ARPG, tower defense) — the pending-damage pattern that prevents over-commit and overkill.

  library/skills/auto-fire-targeting/SKILL.md on GitHub (opens in a new tab)

• brainstorm-game

  Turn a vague idea into a buildable plan — genre, scope, core loop, mechanics, art direction — written as a 1-page brief to .summer/GameSoul.md.

  library/skills/brainstorm-game/SKILL.md on GitHub (opens in a new tab)

• brainstorming

  Explore user intent, requirements, and design before implementation — must run before any creative work: features, components, mechanics, behavior.

  library/skills/brainstorming/SKILL.md on GitHub (opens in a new tab)

• browse-templates

  List available Summer Engine project templates, present the choices, and create a project from the chosen one via summer create.

  library/skills/browse-templates/SKILL.md on GitHub (opens in a new tab)

• celeste-momentum-platforming

  Celeste-style 2D precision platformer movement — momentum running, coyote time, variable jumps, dash, wall jump/slide, climb stamina, pixel corner correction.

  library/skills/celeste-momentum-platforming/SKILL.md on GitHub (opens in a new tab)

• character-animation-wiring

  Wire a rigged, animated character end to end — inspect real clips and bones, locomotion state machine, method-track events, poses, blend shapes, root motion.

  library/skills/character-animation-wiring/SKILL.md on GitHub (opens in a new tab)

• character-model

  Generate a rigged humanoid — player, NPC, enemy, boss — via T-pose reference, user-gated preview, and Meshy auto-rig, wired as CharacterBody3D or Node3D.

  library/skills/character-model/SKILL.md on GitHub (opens in a new tab)

• character-portrait

  Generate a single polished character bust for dialogue UI, character select, lore cards, or codex entries. One character, locked composition, VN-style.

  library/skills/character-portrait/SKILL.md on GitHub (opens in a new tab)

• cinematic-cutscene

  Generate a non-interactive cutscene — reference-locked look, a 5-10s image-to-video shot, optional TTS dialogue — wired as a fading VideoStreamPlayer.

  library/skills/cinematic-cutscene/SKILL.md on GitHub (opens in a new tab)

• concept-art

  Explore art direction with 3-4 rough concept variants of a character, environment, or prop to pick a vibe before committing to a final asset.

  library/skills/concept-art/SKILL.md on GitHub (opens in a new tab)

• create-asset-sheet

  Generate a pack of 2D game assets from one prompt — tile sheet, UI kit, character pack, or biome set — sliced, classified, and saved as one pack ArtAsset.

  library/skills/create-asset-sheet/SKILL.md on GitHub (opens in a new tab)

• debug

  Disciplined bug/crash/error loop for Summer projects — script errors, console, debugger, hypothesis, fix, verify — before making code or scene changes.

  library/skills/debug/SKILL.md on GitHub (opens in a new tab)

• debugging-game-feel

  Debug features that work but feel wrong — floaty jumps, mushy combat, sluggish camera — subjective bugs living in tuning, timing, and feedback layers.

  library/skills/debugging-game-feel/SKILL.md on GitHub (opens in a new tab)

• design-level

  Design a single level — layout, pacing, encounters, secrets, reward gating — outputs a level design doc and a node-tree skeleton for summer_create_scene.

  library/skills/design-level/SKILL.md on GitHub (opens in a new tab)

• design-mechanic

  Design one game mechanic in detail — input, response, feedback, failure modes, depth, tunables — outputs a design doc, node-graph sketch, GDScript stub.

  library/skills/design-mechanic/SKILL.md on GitHub (opens in a new tab)

• design-npc

  Design enemy/NPC/boss/companion behavior — perception, personality, intent, action state machine, telegraphs — outputs a GDScript stub plus node tree.

  library/skills/design-npc/SKILL.md on GitHub (opens in a new tab)

• diagnosing-perf-regressions

  Find why frame rate, frame time, or load time got worse since a known-good state — regression hunting, not general performance tuning.

  library/skills/diagnosing-perf-regressions/SKILL.md on GitHub (opens in a new tab)

• dispatching-parallel-agents

  Work 2+ independent tasks in parallel when they share no state and have no sequential dependencies.

  library/skills/dispatching-parallel-agents/SKILL.md on GitHub (opens in a new tab)

• driving-the-editor-ui

  Drive the editor UI by name: invoke actions, clear blocking dialogs, switch the main screen, read a dock — and route scene work to the scene tools instead.

  library/skills/driving-the-editor-ui/SKILL.md on GitHub (opens in a new tab)

• environment-kit

  Generate a modular environment kit — wall pieces, floor tiles, pillars, doors, arches, corners — snap-together meshes sharing one visual style.

  library/skills/environment-kit/SKILL.md on GitHub (opens in a new tab)

• export-and-ship

  Assess and prepare a game export: inventory installed templates and targets, validate release assets and config, produce supported builds after approval.
