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 | $0.00197 | $0.02702 |
| Opus 5 | $0.00098 | $0.01351 |
| Sonnet 5 | $0.00039 | $0.00540 |
| Haiku 4.5 | $0.00020 | $0.00270 |
Grade A, and why
value 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 — 233 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Injecao de Valores (@Value) — Addon Studio 2.0
@Value injeta valores de configuracao (env vars, system properties, parametros Sankhya) diretamente em campos de componentes gerenciados pelo Guice. Conversao de tipo automatica. Thread-safe.
1. Atributos
| Atributo | Obrigatorio | Descricao |
|---|---|---|
value |
Nao* | Nome da propriedade. Alternativa a param. |
param |
Nao* | Nome do parametro. Alternativa a value. Tem precedencia sobre value. |
group |
Nao | Grupo do parametro — exclusivo de SANKHYA_PARAM. |
type |
Sim | Fonte: ENV_VAR, SYSTEM_PROPERTY, SANKHYA_PARAM ou UNDEFINED. |
defaultValue |
Sim | Fallback quando a propriedade nao e encontrada. Nunca deixar vazio. |
- Ao menos um entre
valueouparame obrigatorio.
2. Eager vs Lazy
| Modo | Sintaxe | Resolucao | Quando usar |
|---|---|---|---|
| Eager | private Integer porta |
Na criacao do objeto | Valor sempre necessario |
| Lazy | private Provider<Integer> porta |
Na primeira chamada .get(), cacheado para sempre |
Valor opcional / custoso — config estavel |
// Eager — resolvido na inicializacao
@Value(value = "server.port", type = ValueType.SYSTEM_PROPERTY, defaultValue = "8080")
private Integer serverPort;
// Lazy — resolvido so quando chamado, DEPOIS congela
@Value(param = "MAX_RETRIES", type = ValueType.SANKHYA_PARAM, defaultValue = "3")
private Provider<Integer> maxRetries;
public void executar() {
int retries = maxRetries.get(); // resolve na primeira chamada; das seguintes vem do cache
// ...
}
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.

value is a skill published in the GitHub repository snk-devcenter/addon-studio (5 stars, last pushed yesterday), licensed MIT. It adds 197 tokens to every session and 2,702 once invoked, about $0.0010 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.
