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 | $0.00276 | $0.06602 |
| Opus 5 | $0.00138 | $0.03301 |
| Sonnet 5 | $0.00055 | $0.01320 |
| Haiku 4.5 | $0.00028 | $0.00660 |
Grade A, and why
sankhya-utils 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 2d 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 — 362 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Utilitários da plataforma — com.sankhya.util
Regra: antes de escrever null-check, validação de vazio, conversão, formatação ou cálculo à mão, procure o equivalente neste índice. Se existe, use.
O pacote vem no classpath junto com a plataforma — não declare dependência no build.gradle, não use moduleLib. Só o import.

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.
- 2d ago First seen · 362 lines · 276 tokens per session scan A cc803893d3da
sankhya-utils is a skill published in the GitHub repository snk-devcenter/addon-studio (5 stars, last pushed 2d ago), licensed MIT. It adds 276 tokens to every session and 6,602 once invoked, about $0.0014 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.
