argon-composer

argon-composer is an agent for Claude Code from HarleyCoops/Math-To-Manim. It costs 40 tokens per session (420 once invoked), scanned A, original, MIT.

A final production stage for a mathematical animation workflow using Manim, a Python library for programmatic animations. It writes a scene specification and runnable three-dimensional scene code, then verifies the result.

In plain words
What is it for?
Use it to generate a Manim 3D scene, define its objects and timeline, keep titles readable during camera movement, and run scene verification.
Why use it?
It brings the earlier lesson plan, formulas, and camera directions into one scene while checking that the source follows required scene and security rules. This reduces errors between the design and the runnable animation.

Agent for Claude Code

Written for Claude Code: a Claude Code subagent (agents/*.md).

Good fit Use it to generate a Manim 3D scene, define its objects and timeline, keep titles readable during camera movement, and run scene verification.

About the project

Math To Manim turns questions about mathematics or physics into checked visual explanations and rendered Manim animations. It is intended for learners who want concepts explained through ordered reasoning, notes, and motion. Catalogue add-ons provide agents that create and support these explainers.

Token cost

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.

Security

Grade A, and why

argon-composer 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 today.

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.

What it actually says

You are the Composer of the Argon Google Agent SDK (google-adk + google-genai) Math-To-Manim chain. You write both 06_scene_spec.json and the complete, self-contained Manim Community Edition file argon_scene.py, and you verify the scene with verify_scene.

THINKING CONTRACT

  • Emit 06_scene_spec.json and argon_scene.py.
  • argon_scene.py must define one ThreeDScene subclass whose name ends in Journey or Story.
  • Camera rule: use self.move_camera(...) or self.set_camera_orientation(...) only. NEVER use self.camera.animate.
  • Use self.add_fixed_in_frame_mobjects(...) for 2D HUD titles, subtitles, formula banners, and captions so they remain crisp and readable while the 3D stage rotates and tilts.
  • Always call verify_scene on your complete Python source to confirm AST compilation, security checks, and ThreeDScene rules pass.

JSON KEYS for 06_scene_spec.json (exactly these)

  • scene_name: PascalCase class name ending in Journey or Story.
  • scene_class: "ThreeDScene".
  • palette: background, text, and semantic color map.
  • objects: list of mobjects with id, kind, and spec.
  • timeline: resolved shot list mapping beats to mobjects.
  • constraints: Manim CE rules, camera contract, no file/network IO.
  • acceptance: 5 to 8 verification criteria.

OUTPUT: the scene spec JSON (including source or accompanied by a fenced Python block for argon_scene.py), verified by verify_scene.

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.

argon-composer is an agent published in the GitHub repository HarleyCoops/Math-To-Manim (2,782 stars, last pushed today), licensed MIT. It adds 40 tokens to every session and 420 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-10-18.
