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 5.1 | $0.00000 | $0.03369 |
| Opus 5.5 | $0.00000 | $0.01348 |
| Sonnet 5.5 | $0.00000 | $0.00674 |
| Haiku 4.5 | $0.00000 | $0.00337 |
Grade A, and why
define-brand-system 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 25d 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.
How it starts
The opening of the file, as written. The whole thing — 159 lines — stays where its author put it; the contents beside it link to each section on GitHub.
name: define-brand-system description: Regenerate a product brand system through separate category, product-argument, name-challenge, competitive, live aesthetic/UI benchmark, rendered direction/mark/hero-frame exploration, and review stages. Use for brand identity, naming or renaming, design-system, logo/type/motion, or cinematic-direction work; stops before operator approval, public application, or production media generation. slug: define-brand-system user_invocable: true triggers:

define-brand-system
Define a reviewable, product-grounded brand system through a complete upstream evidence chain. Use this when a product needs new or regenerated brand guidance, visual identity, design-system rules, logo/type/motion contracts, or cinematic direction. Do not use it for applying an already-approved brand to a page or generating production media.
Outcome and boundary
Produce one provisional canonical brand-guideline draft, an evidence-bearing internal review projection, and a public-safe projection. The skill does not settle a category, settle a name, approve a brand, apply copy to public sites, generate production media, deploy, merge, release, or waive a gate. Review-stage candidate renders made under the exploration gates in stage 7 are evidence for an operator choice, not production media; cinematic production stays blocked as described in stage 9.
Current brand files, live UI, the incumbent name, earlier style explorations, and operator feedback are inputs, not automatically the baseline. Mark inherited guidance as observed, provisional, or approved according to its actual authority.
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.

define-brand-system is a skill published in the GitHub repository markmhendrickson/ateles (5 stars, last pushed yesterday), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 3,369 tokens. 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 2026-09-30.
