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

mike-cartoon-broll 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 11d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/openrouter-video.mjs), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 205 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Mike Cartoon B-Roll

Create short cartoon inserts that break up talking-head footage. Use one strong opening frame, then give the video model room to invent the progression and scene-appropriate audio.

Style

Use assets/cartoon-style-reference.png as the authoritative visual-style reference in every image-generation request. Treat its characters, objects, poses, and composition as examples, not required scene content. Choose the cast from the requested idea. A scene may include Mike, the robot, both, other characters, or neither. In each frame prompt, list the allowed subjects and say the reference controls rendering only, not scene content.

  • Warm ivory paper with visible texture.
  • Fine graphite-and-ink outlines with imperfect cross-hatching.
  • Muted watercolor and gouache fills.
  • Sparse editorial compositions with grounded shadows and negative space.
  • Static wide or medium-wide camera and dry, understated humour.
  • If Mike appears, use his black cap, charcoal T-shirt, dark jeans, and black sneakers.
  • If the friendly robot appears, use its rounded weathered teal body, cream face panel, black oval eyes, mustard antenna ball and chest medallion, and segmented dark limbs.

Preserve Meaning

Before scene ideation, extract the minimum semantic anchors needed for the point to survive. Do not turn every clause into a requirement:

  • Must show: only the causally necessary actors, including who initiates the action and who is affected. Treat an explicitly named team practice, workflow, or real-world setting as required when it is part of the claim rather than incidental background.
  • Must happen: the essential action, who acts on whom, cause, and result.
  • Must change: any essential before-and-after contrast, role change, or emotional reversal.

Use the full script for context. Treat words such as used to, now, but, because, rather than, and instead as prompts to check for a required change or cause, not as automatic duration rules.

What ships with it

3 files 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.

Changes

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.
