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.

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 | $0.00024 | $0.02110 |
| Opus 5 | $0.00012 | $0.01055 |
| Sonnet 5 | $0.00005 | $0.00422 |
| Haiku 4.5 | $0.00002 | $0.00211 |
Grade A, and why
camera-techniques 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 2d 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.

Camera Techniques
Cinematic camera techniques for Manim animations.
MovingCameraScene (2D)
Basic Setup
from manim import *
class MyScene(MovingCameraScene):
def construct(self):
# self.camera.frame is the camera
# It's a VMobject that can be animated
# Save initial state
self.camera.frame.save_state()
# ... scene content
Camera Properties
# Get current properties
self.camera.frame.width # Frame width
self.camera.frame.height # Frame height
self.camera.frame.get_center() # Camera position
# Set properties
self.camera.frame.set(width=10)
self.camera.frame.set(height=6)
Zoom Operations
Zoom In (Make Larger)
# Scale down frame = zoom in
self.play(
self.camera.frame.animate.scale(0.5), # 2x zoom
run_time=2
)
# Zoom to specific height
self.play(
self.camera.frame.animate.set(height=4),
run_time=2
)
Zoom Out (Show More)
# Scale up frame = zoom out
self.play(
self.camera.frame.animate.scale(2), # 0.5x zoom
run_time=2
)
Zoom to Object
# Fit object in frame with padding
target = some_mobject
self.play(
self.camera.frame.animate
.set(height=target.height * 1.5)
.move_to(target),
run_time=2
)
Zoom Levels
| Scale Factor | Effective Zoom | Use Case |
|---|---|---|
| 0.25 | 4x zoom in | Fine detail |
| 0.5 | 2x zoom in | Detail view |
| 1.0 | Normal | Overview |
| 2.0 | 0.5x zoom out | Wide shot |
Pan Operations
Pan to Object
self.play(
self.camera.frame.animate.move_to(target),
run_time=1.5
)
Pan to Coordinates
self.play(
self.camera.frame.animate.move_to([3, 2, 0]),
run_time=1.5
)
Pan with Offset
# Center slightly above target
self.play(
self.camera.frame.animate.move_to(target).shift(UP * 0.5),
run_time=1.5
)
Combined Operations
Zoom + Pan
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-techniques is a skill published in the GitHub repository choxos/MathVizAgent (1 stars, last pushed 3mo ago), licensed MIT. It adds 24 tokens to every session and 2,110 once invoked, about $0.0001 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 2026-08-31.
