Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00023 | $0.00420 |
| Opus 5 | $0.00012 | $0.00210 |
| Sonnet 5 | $0.00005 | $0.00084 |
| Haiku 4.5 | $0.00002 | $0.00042 |
Grade A, and why
sounio-lint 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 12d 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
Sounio Lint — Rust-ism Detector
Scan Sounio source files for common Rust syntax that doesn't belong.
Instructions
-
If a file argument is given, lint that file. Otherwise, lint all
.siofiles in the current directory. -
Run the lint script:
bash scripts/sounio-lint.sh <file> -
If the script is not available, perform manual grep-based detection for these patterns:
Pattern Rule Fix println!orassert!rust-macro Remove !→println(),assert()&mutrust-borrow Replace with &!let mutrust-let-mut Replace with var#[rust-attr Remove attribute, use //@ annotationif testingTrailing ;on statementssemicolons Remove the semicolon |x|lambda syntaxrust-closure Extract to named function + fn ref -
Report findings with line numbers in
file:line: error: rule: descriptionformat -
If
--fixis requested (or user asks to fix), apply corrections using the Edit tool:println!(...)→println(...)assert!(...)→assert(...)&mut→&!let mut→var- Remove trailing semicolons
- Remove
#[...]attribute lines
-
After fixing, run
/sounio-checkto verify the fixes compile
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.

sounio-lint is a skill published in the GitHub repository Sounio-lang/sounio (6 stars, last pushed today), licensed Apache-2.0. It adds 23 tokens to every session and 420 once invoked, about $0.0001 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.
