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 | $0.00124 | $0.03351 |
| Opus 5.5 | $0.00050 | $0.01340 |
| Sonnet 5.5 | $0.00025 | $0.00670 |
| Haiku 4.5 | $0.00012 | $0.00335 |
Grade A, and why
oryxos-lesson-dev 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 2mo 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 — 154 lines — stays where its author put it; the contents beside it link to each section on GitHub.
OryxOS 逐节开发 Skill
User Input
$ARGUMENTS
节号来自上面的输入。设计依据见 docs/class/Harness 设计：用门禁保证每个功能符合预期.md，流程原理见 docs/class/Spec-Kit 执行指导：从课件到代码（以第16节为例）.md——本 skill 是它们的可执行版本，条款以本文为准执行，不需要复读那两份文档给用户。
总纪律（贯穿全程）
能机器判的绝不留给人，机器判不了的绝不自行发挥。
- 硬门禁：测试、
mvn clean verify、存在性核对——不过不放行，不许绕。 - 软门禁：遇到下列任一情况，立即停下、向用户报告、等确认后继续，不得自行决定：
- 需要创建"本节交付物"清单之外的任何对外概念（public 类型、配置键、数据表、REST 路径、Profile 字段）；
- 需要修改任何已定字面量（类名、方法签名、配置键、表列名、端点路径）；
- 课件与
docs/TechnicalSolution.md冲突； - 需要修改前序节交付的公共接口（当节课件明确列为"改造点"的除外）；
- 第三方 API 在本地依赖中核实不到；
- 需要新增 plan 未列明的第三方依赖。
- 反作弊：不得删断言、
@Disabled、放宽阈值让测试变绿。实现错修实现；认为测试错，停下报告。未全绿不得宣称完成。 - 全程不自动 commit / push / 运行 package.sh，同步时机由用户决定。
第 0 步：输入校验与课型分流
解析节号 N，按下表分流；表外输入直接报错退出。
| N | 课型 | 处理 |
|---|---|---|
| 16,17,18,19,20,22,24,25,26,29,30 | 代码课 | 走完整流程（第 1~7 步） |
| 21,23 | 评审课 | 拒绝并说明：这节不产码，是下一节（22/24）的 specify 素材 |
| 27,28 | 串联课 | 特殊模式：不开新 feature，逐条执行该节课件的对账清单，并把对账固化成课件建议的 @Tag("integration") 测试类（27→HumanTriggerFlowIT；28→SchedulerFlowIT/RestartRecoveryIT），然后出报告 |
| 31 | Demo 课 | 特殊模式：按课件定义 weather-daily（走 30 节 API）与 daily-tech-digest（走手写文件）两个 Agent，完成调试对账与发布清单，不做常规模块开发 |
| 其他 | — | 报错：仅支持 16~31 |
第 1 步：H0 开工纪律——必读与依赖检查
- 读三样（用 Read 完整读，不凭记忆）：
- 当节课件：
docs/class/第{N}节*.md（glob 匹配）； docs/TechnicalSolution.md对应章节（映射表见下）；- 前序各代码课课件的"本节交付物"小节。
- 当节课件：
- 依赖存在性检查：对前序每节交付物清单里的核心类，在代码库里 grep/Glob 确认存在。任何缺失 → 停下报告"先做第 X 节"，不得跳节自造。
- 分支：确认当前在该节的 feature 分支上（speckit-specify 的 before_specify hook 会建分支；若 hook 未配置，手动
git checkout -b {NNN}-lesson{N}-<slug>），不在 main/主干上直接开发。
技术方案章节映射表：
| 节 | TechnicalSolution 章节 |

| 17 | §4（ReAct/AgentService/ProfileContext）、§8.3（ContextLoader）、§9.2（tool_invocations） |
| 18 | §8.4、§8.6（CLI）、§9.2（sessions） |

| 25 | §8.5（定时/会话身份） |
| 26 | §7（Web Service） |
| 29 | §11.1~11.2（Skill+Profile、运行时注册） |
| 30 | §11.3~11.4（AgentLifecycleService、/api/v1/agents） |
| 27/28/31 | §12（关键流程/两个 Demo） |
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.

oryxos-lesson-dev is a skill published in the GitHub repository oryx-labs/oryxos (203 stars, last pushed 2d ago), licensed Apache-2.0. It adds 124 tokens to every session and 3,351 once invoked, about $0.0005 per session on Opus 5.5. 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.
