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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00040 | $0.00906 |
| Opus 5 | $0.00020 | $0.00453 |
| Sonnet 5 | $0.00008 | $0.00181 |
| Haiku 4.5 | $0.00004 | $0.00091 |
Grade A, and why
character-appeal 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.
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.

Character Appeal
Think like a casting director watching auditions. Appeal isn't just "cute"—it's magnetic. Characters must demand attention, invite empathy, and feel uniquely themselves.
Core Mental Model
Before animating any character, ask: Why would anyone want to watch this person?
Appeal is the quality that makes audiences invest. It's not prettiness—villains have appeal. It's the sense that this character is worth following. Their movement reveals their soul.
The 12 Principles Through Personality
Appeal — The principle itself. Design and motion that invites connection. Clear silhouette. Readable expression. Movement that expresses inner life. Characters you remember.
Solid Drawing — Characters must have dimensional presence. They need to feel like they could be picked up, like they have weight and mass. Solidity creates believability.
Exaggeration — Personality pushed to clarity. A cautious character is extremely cautious in movement. A bold character moves with unmistakable confidence. Amplify defining traits.
Staging — Present characters for maximum impact. Their best angles, their clearest poses. Give them their spotlight moment. Staging serves character.
Anticipation — Character-specific preparation. How does this particular character wind up for action? A nervous character anticipates differently than a confident one.
Timing — Personal tempo. Every character has their own natural rhythm. Quick and anxious. Slow and deliberate. Timing is personality in motion.
Secondary Action — Habits and quirks. The gestures a character does without thinking. A hair-twirl, a nose-scratch, a weight-shift. Secondary actions individualize.
Follow Through & Overlapping Action — Physical personality. Heavy characters settle differently than light ones. Hair and clothing respond to how the character moves.
Squash & Stretch — Elasticity of personality. Rigid characters barely squash. Flexible personalities stretch easily. The body type reflects the inner type.
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.
