What it does
Goal Manager is an agent skill from nexus-research-lab/nexus. 在当前 Nexus round 中创建、读取、明确纠正、审计、完成或阻塞 durable Goal。只处理用户或系统明确的跨轮目标生命周期；普通任务、提醒和执行图责任分别使用直接执行、Automation 或 Execution。
Its SKILL.md is about 620 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `references/complete-and-block.md`, `references/create-and-retarget.md` and `references/room-goals.md`).
It sits in Agent Workflows. The repository describes itself as: Multi-agent collaboration platform for persistent, proactive AI agents across rooms, workspaces, skills, and external services. The licence is Apache-2.0.

What it can do on your machine
Read from SKILL.md and the folder at commit 67f54e7. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are json).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Goal Manager loads about 616 tokens when it runs, and up to ~3.5k if it reads all its reference files. Until then it costs about 32 tokens; SKILL.md has 182 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- 在当前 Nexus round 中创建、读取、明确纠正、审计、完成或阻塞 durable Goal。只处理用户或系统明确的跨轮目标生命周期；普通任务、提醒和执行图责任分别使用直接执行、Automation 或 Execution。
Goal Manager
Goal 是跨物理 round 持续追求的服务端目标，不是普通聊天、Task、WorkGraph 或 Automation 的别名。Objective 说明最终要实现什么；Execution 另行记录责任如何交付。
入口与命令协议
先通过
nexus.command读取当前 Goal：json {"domain":"goal","action":"inspect"}get_goal是固定入口的语义名：inspect 省略operation，无需request_id，不能通过 invoke 调用。误用时按返回 JSON 纠正，不补参数重试原调用或等待注册。不要使用 shell、临时文件或/goal文本代替 command。读取最新 Goal/objective revision 与 completion criteria 后选择 operation；mutation 前读取 fresh exact contract：
json {"domain":"goal","action":"contract","operation":"<operation>"}完整遵守返回的 contract。
业务输入是
additionalProperties=false的 closed object，直接放在工具的input字段中，只写 fresh schema 暴露的业务字段。不要提交 Goal/owner/Agent/Session/Room/round identity、authority、revision、receipt 或其他隐藏字段。相同语义重试复用 request ID；operation、目标或输入变化时生成新 ID。只有顶层
is_error=false且data.outcome=applied表示状态已改变；nextAction只给 domain-qualified 恢复方向，不携带新 authority，继续前仍读取目标 domain 的 current state 与 exact contract。
按当前动作读取参考
inspect为空且有显式 Goal 意图，或用户明确替换 current objective：references/create-and-retarget.md- 判断 Goal complete/blocked，提交 Goal Objective Alignment，或处理完成拒绝：references/complete-and-block.md
- shared Room Goal 的 Lead、协作与关闭条件：references/room-goals.md
只读取当前动作需要的参考；operation 字段、枚举和长度始终以 fresh exact contract 为准。
暂停与恢复
当 current Goal 为 paused 时，恢复动作由用户执行。请明确告知用户：在当前对话输入框上方的 Goal 状态栏中，点击右侧的 ▶「继续」按钮。
用户点击「继续」后，Nexus 会自动重新调度该 Goal，无需再发一条消息。新的 Goal continuation 负责继续审计和收尾，并在满足完成条件后标记 Goal 完成。
不变量
- 创建前 objective 必须完整、具体、execution-ready；仍缺少会实质改变结果的信息时先取得最少必要输入，不创建占位 Goal。
- current Goal 存在时不创建第二个。用户明确纠正 objective 时 retarget 同一 Goal，保留 identity 与累计用量。
token_budget只在用户明确给出正数预算时设置；暂停、恢复、预算和用量限制属于用户或系统控制面。- Plan Mode 中 Goal mutation 只做 validation，不改变 Goal、Execution、Plan 或 cancellation state；需要持久化时离开 Plan Mode，重新读取 current state 与 exact contract 后再 invoke。
update_goal只标记complete|blocked，不创建、retarget、暂停或改预算。complete 只在 objective 真实满足且没有 required work 时使用；blocked 必须满足连续三次同一 blocker 的模型行为门槛。- 提醒、定时与周期任务使用 Automation；WorkGraph 责任使用
execution-orchestrator。 goal/audit_objective_alignment是 confirmed Goal+WorkGraph 的完成审计；execution/audit_execution_alignment只是非终态 Execution Gate，不能互换。
