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 | $0.00064 | $0.03161 |
| Opus 5 | $0.00032 | $0.01580 |
| Sonnet 5 | $0.00013 | $0.00632 |
| Haiku 4.5 | $0.00006 | $0.00316 |
Grade A, and why
audio-direction 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 9d 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.

/audio-direction — Define the Sonic Identity
Overview
Most indie games sound like a single library used flat. The same generic "swoosh" for menu, jump, pickup, hit. That's not audio direction — that's audio absence. This skill builds an audio bible that names the music style, the SFX vocabulary, the dynamic music plan, and the spatial / mix rules. Writes to .summer/audio-bible.md and configures the audio bus layout in the project so the rest of the work has a real foundation.
Core principle: SFX needs a vocabulary, not a library. Eight named SFX classes with consistent character beat 80 random library hits.
Steps
1. Open with three references
Ask exactly this:
Three reference tracks, games, or films for the music. What instruments matter? And what's the SFX vibe — chunky, clean, synthetic, or organic?
Three is the minimum. One or two collapses into a clone. References are the highest-signal input — listen carefully.
If they freeze, offer four axes (not titles):
Pick the closest: a) orchestral + cinematic (Hollow Knight, Journey), b) lo-fi electronic + ambient (Disco Elysium, Outer Wilds), c) chiptune / synth (Hyper Light Drifter, Celeste), d) acoustic / folk (Sable, A Short Hike).
2. Read the brief and art bible if they exist
Read .summer/GameSoul.md
Read .summer/art-bible.md
Audio must rhyme with the visuals. Quote it back:
Art bible says "soft, hand-warmed, golden-hour, painterly". That rhymes with acoustic / folk / lo-fi over orchestral or aggressive synth. Confirming.
If the brief says "horror", that constrains the music style harder than the user's references will. Name the constraint.
3. Pin the music style
Force one primary style. Sub-styles can blend, but a primary is required.
| Style | Anchor instruments | Pairs with | Avoid |
|---|---|---|---|
| Orchestral cinematic | Strings, brass, choir | Story-led, fantasy | Casual / cozy |
| Acoustic / folk | Guitar, piano, hand percussion | Cozy, narrative | Action / horror |
| Lo-fi electronic | Vintage synth pad, tape sat, light beat | Atmospheric, indie | Combat-heavy |
| Chiptune / synthwave | 8-bit / 16-bit chips, FM synth | Retro, platformer | Realism |
| Industrial / metal | Distorted bass, percussion-led | Horror, action | Cozy |
| Ambient drone | Pads, no drums, slow movement | Walking sim, horror | Action |
| Jazz / fusion | Live instruments, improv | Stylish, narrative | Generic action |
| Tracker / hyperpop | Glitchy, dense, modern | Esoteric, indie | Mass appeal |
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.

audio-direction is a skill published in the GitHub repository SummerEngine/summer-engine-agent (57 stars, last pushed 4d ago), licensed MIT. It adds 64 tokens to every session and 3,161 once invoked, about $0.0003 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 2026-08-30.
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.
