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 | $0.00069 | $0.00494 |
| Opus 5.5 | $0.00028 | $0.00198 |
| Sonnet 5.5 | $0.00014 | $0.00099 |
| Haiku 4.5 | $0.00007 | $0.00049 |
Grade A, and why
aontu 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 1mo 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.
What it actually says
aontu
aontu is JSON plus a lattice. Two documents do not override each other, they unify: the result is the most specific value that satisfies both, or an error naming the contradiction. That makes a definition checkable, queryable and safe to change.
Start here:
- Every JSON document is an aontu document. Write JSON, then add what JSON cannot say.
tasks.md— the verb for a job, indexed by the word you arrived with (ontology, schema, validate, model).grammar-card.md— the whole surface on one page.examples.md— the JSON-superset ladder: plain JSON, then kinds, defaults, templates, constraints.error-codes.md— what a refusal means and what to do about it.
The verbs, all of which answer as JSON with --format json:
aontu vet schema.aontu data.aontu # does this data satisfy that truth?
aontu model get $.a.b file.aontu # what does it say at a path?
aontu model why $.a.b file.aontu # why does that value hold?
aontu model set $.a.b=1 --entry file.aontu --overlay over.aontu
aontu allow --role dev roles.aontu $.a.b # may this role change that subtree?
aontu hash file.aontu # a pin that survives reformatting
These four files also ship INSIDE the command, so they answer with no
network and no checkout: aontu help lists the topics, aontu help language is the grammar card, and aontu explain <code> says what one
refusal means.
What ships with it
7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

aontu is a skill published in the GitHub repository aontu-lang/aontu (11 stars, last pushed yesterday), licensed MIT. It adds 69 tokens to every session and 494 once invoked, about $0.0003 per session on Opus 5.5. 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 2026-08-31.
