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 | $0.00036 | $0.01113 |
| Opus 5 | $0.00018 | $0.00557 |
| Sonnet 5 | $0.00007 | $0.00223 |
| Haiku 4.5 | $0.00004 | $0.00111 |
Grade A, and why
aidd-sudolang-syntax 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 6d 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 — 224 lines — stays where its author put it; the contents beside it link to each section on GitHub.
SudoLang Syntax
A quick cheat sheet for SudoLang syntax.
Interfaces
DisplayTheme { mode: "light" | "dark" name: String parameters{} // each theme can have different sets of parameters permissions[] }
UserPreferences { displayTheme }
User { id: String displayName preferences }
Constraints
constraint: can be specified inline or in block form
Constraints { A constraint Another constraint }
Semantic Pattern Matching
Map conditions to results by meaning:
(pattern) => result
e.g.
(logic is deterministic) => CLI tool, compiled Bun bundle
(logic requires judgment) => AI prompt
Patterns mix naturally into Constraints blocks:
// Real SudoLang agent skill constraints:
Constraints {
Prefer natural language in markdown format
(logic is deterministic) => CLI tool, compiled Bun bundle
(logic requires judgment) => AI prompt
}
Function Definitions
// You can define an inferred function with the fn or function keywords:
fn foo();
function bar();
// You can also define them with function bodies: fn foo() { Constraints { a constraint }
for each (foo) bar() while (!done) work() }
// Functions with blocks can omit the fn or function keyword: anotherFunction() { require user to be signed in }
Function Modifiers
function simple():modifier = value
function complex():nestedModifier={key: "value"}
// You can shape function behavior at call time. doSomethingMultiLine():{ // we can freely mix variable assignments and constraints: format = numbered markdown list lineLength = concise this is a constraint this is another constraint }
Object Literals
updateUser({ id: "123", name: "Pup" })
Template Strings
"foo $bar"
foo $bar
Note: Avoid single quotes for strings, because they are used as apostrophes in natural language, and they can break the syntax hightlighting badly.
// nested template strings: ["foo $bar"]
// nested template strings with objects: { name: "Hello, $name" }
What ships with it
1 file 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.

aidd-sudolang-syntax is a skill published in the GitHub repository paralleldrive/aidd (380 stars, last pushed 2mo ago), licensed MIT. It adds 36 tokens to every session and 1,113 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 2026-08-30.

Explain a topic, a piece of code, an error, or a design decision calibrated to one named audience — a 5-year-old, a 5th grader, a manager, a designer, a graduate student, a parent.
