Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00191 | $0.01794 |
| Opus 5 | $0.00096 | $0.00897 |
| Sonnet 5 | $0.00038 | $0.00359 |
| Haiku 4.5 | $0.00019 | $0.00179 |
Grade D, and why
genart scanned grade D with 2 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 4d 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.
Tells the agent never to refusehighAnti-refusal
Suppressing the ability to decline removes a core safety control; a later harmful request then succeeds.

Omitting safety caveats hides risk from the user and is a common jailbreak preamble.

The opening of the file, as written. The whole thing — 127 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Generative art
Help design, write and check long-form generative artworks — pieces where one algorithm produces a whole edition, each output derived from a hash the blockchain hands you at mint time.
Default practices, and when to break them
These are defaults that work most of the time, not rules. Every one of them has legitimate counter-examples, and those are often the interesting pieces. State the default, then state what breaking it costs.
| Default | Breaking it is legitimate when… |
|---|---|
| All variation comes from the hash | The piece deliberately reads live onchain state (owner, block data). It is then no longer reproducible from the hash alone — own that choice and document it |
| One seeded PRNG, fixed consumption order | Almost never. But named sub-streams let you add a draw without shifting the whole edition — that is how you get flexibility without breaking the property |
| No network, no CDN, no system fonts | Some platforms have an explicit external-asset mode, under their own rules |
| No wall clock | The piece is about time passing, or is genuinely interactive. The preview render must stay stable regardless |
| Sizes relative to the canvas dimension | The piece is deliberately adaptive and reveals more detail with more room. A choice, not an accident — then know what size it will be captured at |
| Runs on current browsers and devices — Chrome, Firefox, Safari, mobile included | A piece built on a bleeding-edge API (WebGPU…) or needing real GPU power is a choice: state the requirement, keep the preview/capture path rendering everywhere, and remember collectors open links on phones |
| Emit the platform's render-done signal | Never. A blank thumbnail is a failure with no upside |
| Features computed before render, from the seed only | Where the platform computes features outside a browser, it is required. Elsewhere it is a convenience |
| Debug code is stripped from the submitted build | Where code is stored unminified and readable onchain, formatting is part of the work |
| Never claim "it's deterministic" without testing it, and without stating the scope | Never |

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.

genart is a skill published in the GitHub repository camilleroux/genart-skill (139 stars, last pushed 5d ago), licensed MIT. It adds 191 tokens to every session and 1,794 once invoked, about $0.0010 per session on Opus 5. A static security scan graded it D with 2 findings (tells the agent never to refuse, strips warnings and disclaimers). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
