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 | $0.03455 | $0.03455 |
| Opus 5 | $0.01728 | $0.01728 |
| Sonnet 5 | $0.00691 | $0.00691 |
| Haiku 4.5 | $0.00346 | $0.00346 |
Grade A, and why
nothing AGENTS.md 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 2d 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 — 207 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Hi robots, welcome to n0 ("nothing") — the Grida graphics engine.
README.md says what this engine is and why. This file is the working map: the laws that bind every change, the commands, the layout, and the caveats that are true right now.
n0 is a 2D graphics engine and a Rust-first Cargo workspace (resolver 3;
members in the root Cargo.toml). The Grida product monorepo — editor,
packages, services — is gridaco/grida; it
consumes this repo only as the published @grida/canvas-wasm npm artifact.
Do not add product/editor code here.
The laws (bind every change)
These are what keep two duty cycles, three source languages, and an editor from becoming three engines. Each has an enforcing mechanism — a law without one is a comment.
-
Never a silent wrong pixel. A construct the compiler cannot honour must refuse loudly (
--strict) or be declared by name at a stable node path (best-effort). A patrol that over-refuses beats one that lets a wrong pixel through. Enforced by: the websem patrols, the refusal corpus, and the law that both admissions are frame-identical where nothing degrades. -
One meaning, many policies. Render modes may differ in when and at what quality they paint — never in what things mean. Static is not a second renderer; it is the same pipeline with an empty temporal input set (no camera delta, no previous frame, no dirty set). Tripwire: a mode, budget, or quality flag must never become readable from
websem,rframe, or resolve. The moment one is, two pipelines have started growing. -
Realtime in structure, static in policy. The architecture that makes realtime possible ships from day one, because retrofitting it is the rebuild. The optimizations realtime needs ship only once measured, because an optimization is a relative claim — same as X, faster — and a cache built over an unverified X becomes a second place that believes the wrong answer. In tree:
DirtyClassis fully classified inn0-model/src/ops.rsand referenced zero times incrates/n0/src. The socket is shaped, the policy is deliberately absent. Do not "finish" it without the gate below.
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.

nothing AGENTS.md is an instructions file published in the GitHub repository gridaco/nothing (43 stars, last pushed 2d ago), licensed Apache-2.0. It adds 3,455 tokens to every session, about $0.0173 per session on Opus 5. 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 2026-08-30.
