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 | $0.00127 | $0.02226 |
| Opus 5.5 | $0.00051 | $0.00890 |
| Sonnet 5.5 | $0.00025 | $0.00445 |
| Haiku 4.5 | $0.00013 | $0.00223 |
Grade A, and why
camera-systems 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
91% identical to camera-systems — 33 lines 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.

Camera systems
The camera is the player's window; bad camera work makes a good game feel awful. This skill covers the engine-neutral camera techniques — smooth follow, deadzones, look-ahead, bounds clamping, third-person orbit with collision, first-person look, and multi-target framing — and maps them onto each engine's camera node or rig.
When to use
- Use when a 2D camera should follow the player smoothly, stay inside the level, lead the player's motion, or ignore small movements (deadzone).
- Use when building a 3D third-person orbit camera (mouse/stick look, collision push-in) or a first-person look controller, or framing multiple targets at once.
- Use to fix camera jitter, snapping, motion sickness, or a camera that shows past the level edge.
When not to use: for the magnitude and trigger of screen shake and impact juice, use
game-feel (this skill exposes the shake offset hook it drives). For the engine's concrete
camera node/component setup, use godot-3d-essentials (Camera3D, environment) or the engine
skill. For player movement itself use the engine movement skill (godot-2d-movement). For
performance of many cameras/render targets, see performance-optimization.
Core workflow
- Decide what the camera serves. Platformer (lead the jump, see hazards), top-down (center with deadzone), third-person (orbit + collision), first-person (look only). The genre sets the rules.
- Follow smoothly and frame-rate independently. Move the camera toward the target with
exponential smoothing or a spring (
SmoothDamp), not a fixedlerp(a, b, 0.1)— that 0.1 is per-frame and changes with frame rate. - Add a deadzone so tiny target movements don't nudge the camera; it only follows once the target leaves a box/zone. Stops nausea in twitchy games.
- Lead the action with look-ahead by offsetting the camera target in the direction of motion or facing, eased in/out so it doesn't whip.
- Clamp to level bounds so the camera never shows outside the playable area; combine with smoothing so it eases to a stop at the edge.
- For 3D, separate look from collision. Orbit via yaw/pitch on a rig; use a spring arm / ray to pull the camera in when geometry blocks it; clamp pitch.
- Update the camera after the target moves. Follow in the late/post step (after movement and physics resolve) to avoid a one-frame lag jitter.
- Verify by moving the target at low and high frame rates, into corners and walls, and at the level edges; confirm no jitter, no peeking past bounds, smooth stops. Report what you saw.
What ships with it

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.

camera-systems is a skill published in the GitHub repository ukanwat/aaabench (385 stars, last pushed 2mo ago), licensed MIT. It adds 127 tokens to every session and 2,226 once invoked, about $0.0005 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 91% identical to camera-systems, differing in 33 lines, and is treated as a copy.
