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.

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 | $0.00054 | $0.00686 |
| Opus 5 | $0.00027 | $0.00343 |
| Sonnet 5 | $0.00011 | $0.00137 |
| Haiku 4.5 | $0.00005 | $0.00069 |
Grade A, and why
nexus-manager scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Nexus Manager
本 Skill 使用 nexusctl 控制面，不处理产品配置。Provider、Agent runtime options、偏好、Channel、Connector 与配置化 Skill 绑定使用 nexus-configuration；Goal、Execution、Automation 使用各自 round-scoped nexus domain。
执行契约
- 优先执行宿主注入的
NEXUSCTL_COMMAND_PATH；示例中的nexusctl代表该入口。Bash 使用"$NEXUSCTL_COMMAND_PATH" --json ...，PowerShell 使用& "${env:NEXUSCTL_COMMAND_PATH}" --json ...。只有宿主没有注入且 PATH 已提供正式二进制时才直接写nexusctl。 - 不探测、覆盖或拼接作用域环境变量，不传隐藏的
--scope-user-id/--global-scope，不搜索源码或go run ./cmd/nexusctl。当前 owner 与 workspace scope 只来自宿主。 - 普通 Agent 在强隔离下不能调用控制面；自己的 workspace 直接使用文件工具。其他资源管理请用户切换到主智能体，不通过数据库、state/runtime 文件或环境变量绕过。
- 所有调用带
--json并作为单独进程执行。成功必须有success=true，再读取domain、action与item|items|report；失败读取结构化error.kind/message和退出码，不从旧字段或混合 stdout 猜结果。 - 先 list/get 当前状态，再执行一个用户授权的 mutation，最后重新读取验证。删除、卸载、移除成员、覆盖 workspace 或清理历史前精确核对目标和影响范围；没有明确删除意图时不执行破坏性命令。
- 低频参数只对选定的 exact subcommand 运行
--help，不要为发现能力加载其他 domain 或凭旧示例补 flag。
按资源读取参考
- Agent 资源与账号管理分流：references/accounts-and-agents.md；创建 Agent 必须读取，其中包含头像选择与默认行为模板字段补全流程。
- DM/Room、conversation、Session 与消息历史：references/rooms-and-sessions.md
- 其他 Agent workspace 文件：references/workspaces.md
- Skill 目录、安装、导入、更新与卸载：references/skills.md
只读取当前资源 domain 的参考，不为一次调用加载完整 nexusctl 手册。
密码、token 和密钥不得出现在命令参数、日志、回复或临时文件。用户账号管理使用 nexus-configuration 的 members 域；密码只在宿主确认卡片中填写，不通过本 CLI 传递。
What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

nexus-manager is a skill published in the GitHub repository nexus-research-lab/nexus (145 stars, last pushed today), licensed Apache-2.0. It adds 54 tokens to every session and 686 once invoked, about $0.0003 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.
