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 | $0.00047 | $0.01590 |
| Opus 5 | $0.00023 | $0.00795 |
| Sonnet 5 | $0.00009 | $0.00318 |
| Haiku 4.5 | $0.00005 | $0.00159 |
Grade A, and why
visual-novel 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 13d 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 — 134 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Visual Novel
A playbook for visual novels — the branching script, the presentation (text box, characters, backgrounds), choices, and the quality-of-life systems players expect (save anywhere, backlog, skip, auto). This is a compositional skill: it drives a dialogue engine and a UI layer. It does not re-teach the dialogue engine or UI nodes; it defines the script model and the player conveniences that make a VN pleasant to read.
When to use
- Use when the game is mostly reading branching text with character art and backgrounds: visual novel, dating sim, branching interactive fiction, story-choice game.
- Use when designing a choice/route structure, story flags, or VN conveniences (backlog, skip, auto-advance, save-anywhere).
When not to use: dialogue as one feature inside a larger game → rpg consuming
dialogue-systems. Card/board play → other genres. For the branching-script engine itself,
use dialogue-systems (Ink / Yarn Spinner).
Core loop
Read a line → advance → (at a branch) make a choice → the story branches on flags/choices → read on → reach an ending. The "game" is the shape of the branching and whether choices feel consequential; everything else is presentation and convenience.
Must-have systems
- Branching script — ordered lines + choices + jumps, with conditions and variables (Ink/Yarn).
- Text box — speaker name, body text, typewriter reveal, advance on click/key.
- Characters — sprites with expressions/poses, positions, show/hide transitions.
- Backgrounds + transitions — scene images, fades/dissolves.
- Choices — present options, gate some on flags, record the pick.
- Story state — flags/variables that branch the script and unlock content.
- Save/load (save-anywhere) — full script position + state; multiple slots; quick save.
- VN conveniences — backlog/history, skip (read text), auto-advance, text-speed setting.
- Audio — music per scene, SFX, optional voice clips.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

visual-novel is a skill published in the GitHub repository gamedev-skills/awesome-gamedev-agent-skills (952 stars, last pushed 2d ago), licensed Apache-2.0. It adds 47 tokens to every session and 1,590 once invoked, about $0.0002 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
assets-get-data
Get asset data from the asset file in the Unity project — every serializable field and property. Supports token-saving path-scoped reads via paths or viewQuery. Use 'assets-find' to find the asset first.
gameobject-set-parent
Reparent a batch of GameObjects under a new parent in the currently opened Prefab or active Scene. Per-item failures are reported in the returned status string instead of aborting the batch. Use 'gameobject-find' to locate the GameObjects first.
unity-version-split
Split a C# file into Unity 6.5+ and pre-Unity 6.5 variants. Use when a file needs different implementations for different Unity versions due to API changes (e.g., EntityId vs int, GetEntityId vs GetInstanceID).
profiler-save-data
Save a snapshot of profiler-derived stats (status + memory + rendering + script + frame capture) to a JSON file. Built-in Unity APIs only.
assets-shader-list-all
List all shaders available in the project assets and packages, sorted by name. Use this to discover a valid shaderName for 'assets-material-create'.
profiler-stop
Disable Unity's runtime profiler. Idempotent — calling when already disabled returns the current disabled state.
