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 | $0.00045 | $0.00201 |
| Opus 5 | $0.00023 | $0.00101 |
| Sonnet 5 | $0.00009 | $0.00040 |
| Haiku 4.5 | $0.00005 | $0.00020 |
Grade A, and why
domainmodel-dsl 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 9d 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
Domain Model DSL
A language for describing a data model as a set of datatypes and entities.
Datatypes
Declare a primitive datatype with the datatype keyword:
datatype String
datatype Int
Entities
An entity groups a set of features. Each feature has a name and a type:
entity Person {
name: String
age: Int
}
The type of a feature can be a datatype or another entity.
Packages
You can group declarations inside a package:
package model {
datatype String
entity Person {
name: String
}
}
That's the core of the language — declare your datatypes, then your entities with their features.
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.

domainmodel-dsl is a skill published in the GitHub repository TypeFox/agent-skills (5 stars, last pushed today), licensed MIT. It adds 45 tokens to every session and 201 once invoked, about $0.0002 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 2026-08-31.
