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 5.1 | $0.00129 | $0.06440 |
| Opus 5 | $0.00064 | $0.03220 |
| Sonnet 5 | $0.00026 | $0.01288 |
| Haiku 4.5 | $0.00013 | $0.00644 |
Grade A, and why
build-deepseek-harness-plugin 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.

构建 DeepSeek Harness 插件
目标
用 Harness 官方的插件装配、Client Slot 和服务 API 实现独立插件。优先扩展公开接口，不修改 Harness 核心、不依赖 DOM 结构、不用全局 CSS 强行覆盖产品界面。
官方入口与证据顺序
先读 official-practices.md。其中区分官方契约、目标版本源码事实和本 Skill 的项目约定。常用官方入口：
- 第一个插件
- 开发一个工具
- 插件配置
- 打包与安装
- 插件与生命周期
- Cordis 入门
- 能力的三种角色设计
- 扩展插件形态实操手册
- Client 模块
- Web UI 样式规范
- Settings
- Credentials
- API Gateway 与 Remote
- 会话内动态包走官方
cordis-plugin-development
master 链接只用于导航。目标版本源码、公开类型和生成的 Catalog 优先于在线文档；版本观察必须记录 commit，不能写成永久 API。
Reference 路由
- 每次任务先读 official-practices.md，记录证据基线。
- 每次任务同时读 version-and-integration-boundaries.md，先确定版本分支、启动宿主和后置覆盖层。
- 搭包、配置、构建或检查产物时读 package-and-build.md。
- 做 Client Slot、主题、本地化或界面时读 client-slots-and-theme.md。
- 做持久化、Remote、Settings、Credentials、安装或发布时读 persistence-and-release.md。
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.

build-deepseek-harness-plugin is a skill published in the GitHub repository oil-oil/build-deepseek-harness-plugin (43 stars, last pushed 2d ago), licensed MIT. It adds 129 tokens to every session and 6,440 once invoked, about $0.0006 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.
