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 | $0.00145 | $0.02859 |
| Opus 5 | $0.00072 | $0.01430 |
| Sonnet 5 | $0.00029 | $0.00572 |
| Haiku 4.5 | $0.00015 | $0.00286 |
Grade A, and why
encoding 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 yesterday.
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 — 235 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Codificacao de Arquivos — Addon Studio 2.0
REGRA CRITICA — SEM EXCECOES
Todo arquivo .java, .xml, .kt e .properties em projetos Addon Studio deve ser salvo em ISO-8859-1 (Latin-1).
Por que ISO-8859-1
O servidor Sankhya (Wildfly legado) e o compilador de addons esperam Latin-1. Arquivo salvo em UTF-8 causa corrupção de acentos e falha silenciosa em runtime.
Regras
| Tipo de arquivo | Regra |
|---|---|
.java / .kt |
Salvo em ISO-8859-1. Acentos diretamente no encoding ou escapados como é, ç etc. |
.xml (datadictionary, dbscripts) |
Salvo em ISO-8859-1. Cabecalho obrigatorio: <?xml version="1.0" encoding="ISO-8859-1" ?> |
.properties |
Salvo em ISO-8859-1 (formato historico do Java 8 para properties). |
O problema com LLMs
LLMs geram arquivos em UTF-8 por padrao. Apos criar ou editar qualquer .java, .xml, .kt ou .properties, converta o encoding antes de usar.
Antes de converter, cheque o charset atual (
file -i arquivo.java). So converta se o resultado forcharset=utf-8. Arquivo ja em ISO-8859-1 reconvertido de "UTF-8" pode ter acentos corrompidos; eerrors='ignore'/errors='replace'apagam ou trocam caracteres silenciosamente.
Mac / Linux — iconv (nativo, preferido)
Duas guardas são obrigatórias em toda conversão: charset atual (só converter UTF-8) e
ausência de U+FFFD (ver Perda silenciosa de acento).
Sem elas a conversão troca acento por ? sem avisar.
# Arquivo especifico — NUNCA use o mesmo arquivo como entrada e saida (trunca o arquivo!)
f=arquivo.java
if grep -qF "$(printf '\357\277\275')" "$f"; then
echo "PERDA: U+FFFD em $f -- restaure via git antes de converter"
else
case $(file -bi "$f") in *utf-8*)
t=$(mktemp) && iconv -f UTF-8 -t ISO-8859-1 "$f" > "$t" && cat "$t" > "$f" && rm -f "$t" ;;
esac
fi
# Todos os .java do projeto (idem para *.xml, *.kt e *.properties)
find . -name "*.java" -exec sh -c '
grep -qF "$(printf "\357\277\275")" "$1" && { echo "PERDA: U+FFFD em $1"; exit 0; }
case $(file -bi "$1") in *utf-8*)
t=$(mktemp) && iconv -f UTF-8 -t ISO-8859-1 "$1" > "$t" && cat "$t" > "$1" && rm -f "$t" ;;
esac' _ {} \;
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.

encoding is a skill published in the GitHub repository snk-devcenter/addon-studio (5 stars, last pushed yesterday), licensed MIT. It adds 145 tokens to every session and 2,859 once invoked, about $0.0007 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.
