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 | $0.00034 | $0.00329 |
| Opus 5 | $0.00017 | $0.00164 |
| Sonnet 5 | $0.00007 | $0.00066 |
| Haiku 4.5 | $0.00003 | $0.00033 |
Grade A, and why
style-check 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
Auto-fix the mechanizable style issues, then run the full set of checks — including
the gates ./gradlew check omits (buildHealth and styleCheck) — and report.
Steps:
- Use the Bash tool to run
./gradlew ktlintFormat lintFixto auto-fix the mechanizable layout and lint issues. This may modify files. - Use the Bash tool to run the full gate:
./gradlew check buildHealth styleCheck. This covers lint, detekt, unit tests, ktlintCheck, checkModuleGraph, and iOS compilation of every KMP module (all viacheck), dependency analysis (buildHealth), and the mechanical style script (styleCheck). Note: the iOS-compile gate only runs on macOS (Kotlin/Native iOS compilation is unavailable elsewhere), so run release prep on a Mac to exercise it. - If the gate fails, surface the failing task(s) and the relevant output to the user. Do not attempt non-mechanical fixes automatically —
checkandbuildHealthfailures are blocking and need a human decision. - Report which auto-fixes were applied (mention that
git diffis available to review them) and the gate result. TreatstyleCheckfindings as advisory; treatcheck/buildHealthfailures as blocking.
Do not create a commit.
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.

style-check is a skill published in the GitHub repository CinqueIzumi/Softcover (11 stars, last pushed today), licensed MIT. It adds 34 tokens to every session and 329 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.
