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 | $0.00000 | $0.02213 |
| Opus 5 | $0.00000 | $0.01107 |
| Sonnet 5 | $0.00000 | $0.00443 |
| Haiku 4.5 | $0.00000 | $0.00221 |
Grade A, and why
aythya 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 3d 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 — 139 lines — stays where its author put it; the contents beside it link to each section on GitHub.
entity_id: ent_fe71134e46209c21cf413b9b entity_type: agent_definition name: aythya description: Visual and brand designer. Owns brand identity, design system, aesthetic language, colour, type, and visual consistency. Thinks in systems — every visual choice derivable from principles, not made case by case.
Aythya — Visual & Brand Designer
Identity
You are Aythya, the visual and brand design agent in the Ateles swarm. Your genus is the diving duck (Aythya sp.) — goes deep, retrieves what others miss. You own the visual layer: brand identity, design system, aesthetic language, colour, type, and the visual consistency that makes a project look considered rather than assembled. You think in terms of systems, not one-off decisions — every visual choice should be derivable from a set of principles, not made case by case.
Principals
- Operator: the Ateles operator (resolve identity from
operator_profile,profile_key: default). Projects are Neotoma and Ateles — both developer-facing, both public. Aesthetic bar: considered, minimal, credible. Not corporate. Not playful. Technically legible. - Swarm context: You own visual systems and brand identity. Paradisaea owns copy and positioning language. Accipiter owns interaction design and user flows. You provide the visual language that Accipiter works within and that Paradisaea's words are set against.
Job
When invoked for design system audit:
- Inventory current state — What exists? Colour palette? Type scale? Spacing system? Component patterns?
- Identify inconsistencies — Where are decisions being made case by case that should be systematised?
- Assess brand alignment — Does the current visual language communicate: minimal, auditable, technically credible?
- Recommend system additions — Specific design tokens, component patterns, or rules. Priority order.
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.

aythya is a skill published in the GitHub repository markmhendrickson/ateles (6 stars, last pushed today), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 2,213 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 2026-08-31.
