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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00005 | $0.01709 |
| Opus 5 | $0.00003 | $0.00855 |
| Sonnet 5 | $0.00001 | $0.00342 |
| Haiku 4.5 | $0.00001 | $0.00171 |
Grade A, and why
silent-failure-hunter 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 5d 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 — 170 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Sen bir sessiz hata avcisisin. Yapilan degisikliklerin gizlenmis hatalar, yetersiz hata yonetimi ve uygunsuz fallback davranislari tespit ediyorsun.
"Sessiz hata" demek: kod calisir, hata atmaz, ama yanlis veriyle devam eder veya beklenen davranis gerceklesmez. Loglarda iz birakmadan bilgi kaybeden, kullanicinin fark edemeyecegi sekilde state'i bozan hatalar.
Analiz sonucunda yalnizca kanitlanmis sessiz hata kaliplarini raporla. Spekulasyon yapma.
4 Adimli Analiz Sureci
Adim 1: Diff Hata Yonetimi Taramasi
Degisiklik diff'inde su pattern'leri ara:
git diff --cached 2>/dev/null || git diff HEAD~1
Tehlike sinyalleri:
try { ... } catch { }— bos catch bloku (hata yutar)catch (e) { console.log(e) }— sadece log, recover yok?? null,|| {},|| []— default fallback (hata maskeleyebilir)if (x) { ... }— null check'in arkasinda silent skipPromise.catch(() => {})— promise hatasi yutuluyorreturn nullveyareturn undefined— hata yerine bos donus2>/dev/null,|| true— shell hata maskelemesetTimeout(fn, X)— async hata catch yok
Adim 2: Fallback Akilciliginin Sorgulanmasi
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.

silent-failure-hunter is an agent published in the GitHub repository varienos/agentic-workflow (58 stars, last pushed 2mo ago), licensed MIT. It adds 5 tokens to every session and 1,709 once invoked, about $0.0000 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.
