goal-manager

goal-manager is a skill for Claude Code, Codex from nexus-research-lab/nexus. It costs 55 tokens per session (918 once invoked), scanned A, original, Apache-2.0.

Instructions for managing a durable goal across multiple work sessions in Nexus, including creating, inspecting, correcting, completing, or blocking it.

In plain words
What is it for?
Use them when a user explicitly needs an ongoing objective tracked across sessions and its status updated as work progresses.
Why use it?
They distinguish long-running goals from ordinary tasks and require the current goal, completion criteria, and exact operation rules to be checked before changes.

Token cost

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.

Security

Grade A, and why

goal-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.

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

  1. 先通过 nexus.command 读取当前 Goal:

    {"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。

  2. 读取最新 Goal/objective revision 与 completion criteria 后选择 operation;mutation 前读取 fresh exact contract:

    {"domain":"goal","action":"contract","operation":"<operation>"}
    

    完整遵守返回的 contract。

  3. 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。

  4. 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=falsedata.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

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。

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.
