Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00105 | $0.04532 |
| Opus 5 | $0.00053 | $0.02266 |
| Sonnet 5 | $0.00021 | $0.00906 |
| Haiku 4.5 | $0.00011 | $0.00453 |
Grade A, and why
cinematic-cutscene scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 241 lines — stays where its author put it; the contents beside it link to each section on GitHub.
cinematic-cutscene — Locked-Look Story Beat in 5-10 Seconds
A cutscene is a non-interactive video clip the game plays back at a fixed moment — opening, story beat, character intro, ending. Quality is dominated by two things: continuity (the character on screen looks like the character in the game) and shot length (every clip past 10s drifts in identity, hands, and physics). This skill enforces both — generate a reference image first to lock the look, then image-to-video each shot, then chain shots in sequence rather than asking the model for one long take.
If the user wants 5 seconds of marketing footage, that's video/trailer-shot. If they want a 3-second seamless background loop, that's video/animated-loop. This skill is for narrative beats with a defined start, middle, and end — usually with dialogue or VO.
When to use
- "Generate the opening cinematic for the game."
- "I need a cutscene where the witch turns to the player and warns them about the curse."
- "Make a 10-second character intro for the boss."
- "Add an ending sequence after the player defeats the dragon."
- "Cinematic where the village burns and the protagonist runs."
- The user has a defined moment with story content — not a vibe loop, not a marketing splash.
When NOT to use
- "5-second slow-mo combat shot for the trailer" —
video/trailer-shot. - "Looping splash screen background" —
video/animated-loop. - "Animated logo backdrop on the title screen" —
video/animated-loop. - Real-time in-engine cinematic with the actual gameplay characters and camera — that's a Godot AnimationPlayer / Timeline job, not generated video. Route to
summer:scene-composition. - Voice-only narration over a static image — generate the dialogue with
summer_generate_audioand use a staticTextureRect, no video needed.

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

cinematic-cutscene is a skill published in the GitHub repository SummerEngine/summer-engine-agent (59 stars, last pushed yesterday), licensed MIT. It adds 105 tokens to every session and 4,532 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
Other skills, from other repositories
artist-self-evolve
Distill stable art-generation patterns from a completed project, so future projects produce comparable assets without re-discovering the prompts. Lead-dispatched only — orchestrator invokes this skill from its self-evolve flow with a game-slug message; do not self-trigger.
vibegame-edit
Iterate broadly on an existing game, on top of vibegame-build. Use when the user asks to change an existing game's art style, genre, or core rules. Not for local tuning such as numbers or game feel. Orchestrator only.
hearth-art
Give a Hearth game real art and sound — importing and slicing spritesheets, animations, procedural sprites and sounds, autonomous CC0 asset sourcing (Kenney, itch.io, OpenGameArt, Freesound, Google Fonts) with licensing rules, and pixel-art discipline (never stretch; read the art before using it). Use when the game…
asset-gen
Generate visual assets from text prompts: PNG images (Gemini / xAI Grok), GLB 3D models (Tripo3D), rigged biped characters, retargeted animations, and frame-by-frame animated sprites, plus background removal. Use whenever a game needs generated art.
screenshot-isolated
Render a target GameObject from a chosen camera angle with optional layer-based isolation, configurable background (solid/skybox/transparent), multi-light setup via JSON, and Composite (2x2 Front/Right/Back/Top) mode. Returns a PNG image. When isolated=true, inactive children may briefly fire OnEnable — see the body…
screenshot-camera
Capture a screenshot from a Unity Camera and return it as a PNG image for direct LLM inspection. Falls back to Camera.main (then any active camera) when cameraRef is null. Width and height are capped to keep response size manageable.
