What it costs to keep this loaded
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 | $0.00045 | $0.01458 |
| Opus 5 | $0.00023 | $0.00729 |
| Sonnet 5 | $0.00009 | $0.00292 |
| Haiku 4.5 | $0.00005 | $0.00146 |
Grade A, and why
lumina_json_serialization 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 11d 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

Lumina JSON 序列化规范
功能概述
本技能包用于确保 Lumina 框架项目统一使用 Jackson 进行 JSON 序列化和反序列化,包括注解使用、日期格式化、空值处理等。
核心原则
- 统一使用 Jackson - 所有 JSON 序列化/反序列化使用 Jackson
- 禁止使用 Fastjson2 - 项目中不再使用 Fastjson2
- 统一配置 - 使用 Spring Boot 默认的 Jackson 配置
- 注解优先 - 使用 Jackson 注解进行字段控制
Jackson 基础使用
DTO 中的注解使用
@Data
public class AgentVO {
private Long agentId;
private String agentName;
// 日期格式化
@JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss", timezone = "GMT+8")
private LocalDateTime createTime;
// 忽略字段
@JsonIgnore
private String internalField;
// 字段重命名
@JsonProperty("agent_type")
private AgentType agentType;
// 空值处理
@JsonInclude(JsonInclude.Include.NON_NULL)
private String description;
}
全局配置
@Configuration
public class JacksonConfig {
@Bean
@Primary
public ObjectMapper objectMapper() {
ObjectMapper mapper = new ObjectMapper();
// 日期格式
mapper.setDateFormat(new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"));
mapper.setTimeZone(TimeZone.getTimeZone("GMT+8"));
// 空值处理
mapper.setSerializationInclusion(JsonInclude.Include.NON_NULL);
// 忽略未知属性
mapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
// 美化输出(开发环境)
mapper.enable(SerializationFeature.INDENT_OUTPUT);
return mapper;
}
}
常用注解
@JsonFormat
用于日期时间格式化:
@JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss", timezone = "GMT+8")
private LocalDateTime createTime;
@JsonFormat(pattern = "yyyy-MM-dd", timezone = "GMT+8")
private LocalDate createDate;
@JsonIgnore
忽略字段:
@JsonIgnore
private String password;
@JsonIgnore
private String internalField;
@JsonProperty
字段重命名:
@JsonProperty("agent_id")
private Long agentId;
@JsonProperty("agent_name")
private String agentName;
@JsonInclude
空值处理:
@JsonInclude(JsonInclude.Include.NON_NULL)
private String description;
@JsonInclude(JsonInclude.Include.NON_EMPTY)
private List<String> tags;
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.

lumina_json_serialization is a skill published in the GitHub repository zwl467135974/lumina (66 stars, last pushed 21d ago), licensed Apache-2.0. It adds 45 tokens to every session and 1,458 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.
