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 | $0.00019 | $0.00729 |
| Opus 5.5 | $0.00008 | $0.00292 |
| Sonnet 5.5 | $0.00004 | $0.00146 |
| Haiku 4.5 | $0.00002 | $0.00073 |
Grade A, and why
pc-games 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 1mo 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.
This is a copy
92% identical to pc-games — 1 line differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

PC/Console Game Development
Engine selection and platform-specific principles.
1. Engine Selection
Decision Tree
What are you building?

Comparison
| Factor | Unity 6 | Godot 4 | Unreal 5 |
|---|---|---|---|
| 2D | Good | Excellent | Limited |
| 3D | Good | Good | Excellent |
| Learning | Medium | Easy | Hard |
| Cost | Revenue share | Free | 5% after $1M |
| Team | Any | Solo-Medium | Medium-Large |
2. Platform Features
Steam Integration
| Feature | Purpose |
|---|---|
| Achievements | Player goals |
| Cloud Saves | Cross-device progress |
| Leaderboards | Competition |
| Workshop | User mods |
| Rich Presence | Show in-game status |
Console Requirements
| Platform | Certification |
|---|---|
| PlayStation | TRC compliance |
| Xbox | XR compliance |
| Nintendo | Lotcheck |
3. Controller Support
Input Abstraction
Map ACTIONS, not buttons:
- "confirm" → A (Xbox), Cross (PS), B (Nintendo)
- "cancel" → B (Xbox), Circle (PS), A (Nintendo)
Haptic Feedback
| Intensity | Use |
|---|---|
| Light | UI feedback |
| Medium | Impacts |
| Heavy | Major events |
4. Performance Optimization
Profiling First
| Engine | Tool |
|---|---|
| Unity | Profiler Window |
| Godot | Debugger → Profiler |
| Unreal | Unreal Insights |
Common Bottlenecks
| Bottleneck | Solution |
|---|---|
| Draw calls | Batching, atlases |
| GC spikes | Object pooling |
| Physics | Simpler colliders |
| Shaders | LOD shaders |
5. Engine-Specific Principles
Unity 6
- DOTS for performance-critical systems
- Burst compiler for hot paths
- Addressables for asset streaming
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.
- 1mo ago First seen · 144 lines · 19 tokens per session scan A 61a82d7cc087
pc-games is a skill published in the GitHub repository felipeslo/opencode-kit (2 stars, last pushed 7mo ago), licensed MIT. It adds 19 tokens to every session and 729 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 92% identical to pc-games, differing in 1 line, and is treated as a copy.

godot-signals-groups
Build event-driven, decoupled Godot 4.7 gameplay with signals and node groups: declare and emit custom signals, connect with Callables (incl. bind/one-shot), and broadcast to many nodes via groups and callgroup. Use when wiring node communication in a Godot project, replacing tight references with signals…

Reconstruct a skeleton from calibrated mesh projections and sequential VLM joint annotations, then fit joints and skin weights. Generate motion from joint-position trajectories, rhythm and contact constraints through IK; refine bone orientation against the action, then export, retarget and validate on the target mesh.
