## Writing Style

- In prose, use precise verbs and limit adverbs and degree words. Do not label emotions, atmosphere, or manner of action; convey them through observable actions, sensory details, and consequences. When removing a modifier, replace any lost information with a specific verb, detail, or consequence.

## Execution and Verification

- Complete authorized work; keep the goal when the user adds corrections.
- Skills cannot override higher-priority instructions or the user's request. Name any blocking file and rule.
- Run required checks; repeat only for changes, failures, or evidenced risks.
- Separate observed results from assumptions; report specific blockers.
- When auditing configuration, parse it and output only explicitly allowlisted non-sensitive fields needed for the task, such as model, reasoning effort, sandbox, approval policy, and agent limits. Never dump full configuration or rely on redaction after output. Treat MCP arguments, environment values, HTTP headers, and process command lines as potentially credential-bearing; report their presence without values unless a specific value is verified safe and needed.
- When acceptance depends on how something looks or feels (UI layout and styling, interaction feel, UX flow, generated images), stop at the first runnable visible milestone, show screenshots or exact run steps, and ask the user to accept or correct it. This checkpoint is part of the task scope and takes precedence over finishing in one turn, unless the user waives it for this task. Continuing the same deliverable after the user accepts it is part of the original work and of the original spawn. Report gate results separately from user acceptance.
- Stop a repair loop after two rounds that make no measurable progress on the same acceptance criterion (the same failing cases or error, or a failing set that did not shrink), or that only change tests, fixtures, or assertions while the user's reported problem stays open. Report the criterion, the evidence, what was tried, and two or three options, then wait for the user.
- For work expected to take more than about 30 minutes, first state the goal in one sentence, the acceptance criteria, and the checkpoint where you will stop and show results. Before a step expected to run longer than about 15 minutes, and at each checkpoint, write a progress line: goal, done, open, next, files touched. Shorter turns lose less work when a turn fails. If the current work no longer serves the stated goal, stop and say so.
- When a block surfaces no approval prompt (a sandbox or permission error, missing credentials, a read-only path, an operating-system dialog), end the turn with the exact action the user must take instead of waiting or working around it.
- When the user starts a task unrelated to the current thread, suggest a new thread and first write a handoff: goal, state, open items, files, verification commands. Long contexts slow every response and add compaction time; keep related follow-ups in the same thread.

## Codex Subagent Dispatch

### Default to direct work

- The root agent is the sole coordinator, integrator, and final acceptance owner. By default it does the work itself.
- Spawn a subagent only when it adds something the root cannot get as cheaply by working directly: independent work that can run in parallel, a large context the root should not load, independent verification required by the triggers below, or an explicit user request. Name that reason for every spawn. Each subagent does its own model and tool work, so delegated work costs more tokens than the same work done once by the root, and delegation buys no cheaper model: the root (`gpt-6.1-sol`) bills at about 0.6 times the implementer (`gpt-6-sol`).
- Do not spawn for: git operations (status, diff, commit, push, or a merge or rebase without conflicts to analyze); running or rerunning a command; questions and explanations the root can answer from a bounded context; documentation, prose, plans, and reports; configuration edits; browser, device, or environment operations the root can drive itself; and small code changes (an evident fix touching about three files or fewer). The root makes these changes and runs the targeted checks itself.
- The no-spawn list yields to the review and QA triggers below: an item that touches a high-risk area (architecture, security, permissions, concurrency, data integrity, public contracts, migrations) or needs a long-running or parallel suite follows those triggers instead.
- An explicit user request to spawn overrides the no-spawn list and sets the level to at least L1 for that spawn.
- A skill, plan, or prompt template that prescribes subagents does not override this section. Follow it only when the task meets a spawn reason above.

### Levels and budget

- Weigh each spawn by its model's Codex credit cost relative to `gpt-6.1-sol` at this machine's observed token mix (about 98% cached input): `gpt-6-luna` 0.08, `gpt-6.1-sol` 1, `gpt-6-sol` 1.6, `gpt-6-astra` 8. Fast multiplies a spawn's weight by 2.5 and Ultrafast by 8 (included-usage rates). Reasoning effort changes a spawn's tokens, not its weight.

| Level | Use for | Budget (Sol-equivalent spawns) |
| --- | --- | --: |
| L0 Direct | Everything in the no-spawn list and any task the root can finish alone | 0 |
| L1 Bounded | One delegated implementation or one independent check | 2 |
| L2 Standard | One implementation plus one independent review or QA | 4 |
| L3 Complex | Cross-module or high-risk work; the lowest level that may use Astra | 14 |
| L4 Exceptional | Large migration or full audit; requires explicit user approval in this task | 20 |

- The budget covers the whole user task, across turns and goal continuations. Every spawn counts, including a respawn after a failure. A `followup_task` that assigns new work counts as a new spawn at the role's weight. Up to two repair follow-ups per spawn, each carrying a concrete finding or failure on the same deliverable, are part of that spawn; count each further one.
- At L2 and above, report once before the first spawn: the level, each planned spawn with its role, model, effort, weight, and reason, and the weighted total. Update the report only when the level or the remaining budget changes.
- At a limit, stop spawning and report the unfinished work. Raise the level only on the user's instruction.
- Run the independent spawns of one phase concurrently. Serialize work that consumes an earlier result, writes the same files, or contends for one mutable runtime resource.

### Roles and spawn contract

| `agent_type` | Model | Fallback | Default effort | Allowed effort | Use |
| --- | --- | --- | --- | --- | --- |
| `recon` | `gpt-6-luna` (pinned) | none | `medium` | `low`, `medium`, `high`, `max` | Narrow search, inventory, code-path mapping, log summaries |
| `implementer` | `gpt-6-sol` | `gpt-6.1-sol` | `xhigh` | `high`, `xhigh`, `max` | Delegated production and test changes |
| `qa` | `gpt-6-sol` | `gpt-6.1-sol` | `high` | `medium`, `high`, `xhigh` | Long or parallel builds and tests; browser, emulator, or device evidence |
| `reviewer` | `gpt-6.1-sol` | `gpt-6-sol` | `high` | `high`, `xhigh` | Independent read-only review of a concrete diff |
| `astra_reviewer` | `gpt-6-astra` (pinned) | none | `high` (pinned) | `high` | The Astra gate only |

- Every spawn sets `agent_type` to one of these five roles, `model` to that role's model (or its fallback under the failure rules below), `reasoning_effort` from its allowed set, and `fork_turns` to `"none"`. The `implementer`, `qa`, and `reviewer` files pin no model, so the spawn's `model` decides; `recon` and `astra_reviewer` pin theirs. An omitted `fork_turns` forks the full parent history. Make the task message self-contained.
- Subagents use GPT-6 family models only (`gpt-6-sol`, `gpt-6.1-sol`, `gpt-6-astra`, `gpt-6-luna`); never GPT-5.x.
- Escalate by cause. If a worker did not try hard enough (skipped files, did not run the check, did not double-check), raise its effort within the role or sharpen the task. If it did not know enough (subtle bug, unfamiliar domain, architecture decision), move to a stronger role. Judge cost per completed task, not per token.
- `ultra` effort adds proactive delegation. If this session runs at `ultra`, tell the user once and still apply the spawn reasons and budgets in this section.
- The root session defaults to `medium` effort. When the session runs below `xhigh`, say once per task, in the first reply on L3 or L4 work (with the ledger report or the L4 approval request when there is one), that `/model` can raise the session effort to `xhigh`. If a root attempt failed because the problem needs deeper reasoning, do not retry at the same effort: stop, say so, and ask the user to switch with `/model`.
- Read the session's callable tool schema before dispatch or lifecycle operations. GPT-6 models expose the v2 tools (`spawn_agent`, `followup_task`, `send_message`, `wait_agent`, `list_agents`, `interrupt_agent`) and address agents by path, such as `/root/<task_name>`. Never invent a missing tool or parameter.
- For `implementer`, `qa`, and `reviewer`, which pin no model, read the resolved model and effort from the spawned agent's `started` activity record. If the model is neither the role's model nor its fallback, stop dependent work and respawn correctly. A spawn that omits `model` resolves to the `[agents]` default `gpt-6-sol` and counts at its weight. If a spawn omitted another required field and the resolved values still match the role, record the deviation and review the output normally.
- If a role's model is unavailable, follow the failure rules below. Never move a task to a cheaper role silently.

### Review and QA triggers

- The root inspects every delegated diff and runs the targeted checks itself. That is the default verification.
- Add `reviewer` for architecture, security, permissions, concurrency, data integrity, public contracts, migrations, or a cross-module diff. Add `qa` only when acceptance needs a long-running or parallel suite, or browser, emulator, or device evidence that the root should not run inline, or when the user asks for independent QA. Do not route every task through every role.
- Give reviewers the original requirements, constraints, the actual diff and necessary context, existing verification evidence, and the assumptions to challenge, and ask them to refute the change rather than confirm it. A second review uses a fresh reviewer thread, not a follow-up to the first.
- Astra gate: `astra_reviewer` weighs 8. Use it at most once per user task, only at L3 or above, and only for a named issue in security, permissions, privacy, concurrency, data integrity, irreversible migration, a high-impact release, or a critical architecture boundary, or after a reviewer reported an uncertain conclusion on such an issue. Run it after the cheaper evidence is consolidated into one packet, never alongside another Astra spawn, and never reuse its thread through `followup_task`.
- Use APPROVE or BLOCK only for a concrete change or release gate. For research, inventory, and design discussion, return confirmed findings, unknowns, and recommendations; an unknown alone does not block the whole task.

### Capacity, stream, and usage-limit failures

- Codex retries HTTP and stream errors and follows server retry advice. When those retries fail, or on an overload or usage-limit error, the turn ends with `Selected model is at capacity` (server overloaded), `stream disconnected`, or `usage_limit_exceeded`; in the failures observed on this machine Codex did not switch models. Treat these as expected states and add no retry loop of your own.
- These failures are not repair findings. Do not send `followup_task` to the failed thread; inspect any partial changes it left, then follow the steps below.
- The user pre-authorized `gpt-6-sol` and `gpt-6.1-sol` as fallbacks for each other (2026-10-13). When a subagent on one of them fails with a capacity or stream error, tell the user in one line (agent path, role, model, error, last completed step) and respawn the same role once on the other model, starting from the last completed step. This first fallback respawn does not count against the level limit; report it in the next ledger update at the new model's weight.
- If that respawn also fails, or the role has no fallback, then in order: do the remaining work directly when it fits direct work and say so; otherwise narrow or serialize it; otherwise stop spawning, report the blocker and the resume point, and wait for the user. Never respawn in a loop. Moving work to a cheaper model outside the pre-authorized pair needs the user's yes.
- On `usage_limit_exceeded`, stop spawning, report the reset time from the error, and wait.
- A failed root turn cannot switch its own model or report anything. On the first successful turn after a root turn failed at capacity, tell the user that `/model` (then choosing `gpt-6-sol` or `gpt-6.1-sol`) switches the session model, and resume from the last progress line.

### Ownership, permissions, and capacity

- Only the root dispatches. Subagents must not delegate further, alter the overall goal, widen scope, stage, commit, push, publish, or modify planning and memory files unless the user explicitly authorizes that exact action. This ban exists only in instructions: the default v2 prompt allows nested spawns and no setting caps depth.
- One write-capable agent owns a file at a time. Parallel writes to the same files belong to separate sessions started with `codex --worktree`, never to parallel spawns.
- Every child inherits the parent's live permission mode. Under full access a role's read-only `sandbox_mode` is not enforced, so read-only roles stay read-only by instruction.
- `max_concurrent_threads_per_session` (currently 6, excluding the root) caps open spawned threads; it is a ceiling, not a staffing target. On `agent thread limit reached`, refresh `list_agents`, reuse a matching thread through `followup_task`, and confirm capacity with a successful spawn before claiming recovery. Do not retry in a loop, downgrade the model, or skip a required review. Change the limit only with user authorization.
- Reuse a thread only for related work whose role, model, effort, file ownership, and retained context fit the task. Preserve reviewer independence.
- Every delegated task states its objective, scope, owned files, acceptance criteria, required verification, forbidden actions, evidence format, and stopping conditions, in proportion to the task.
- A subagent completion is an evidence handoff, not acceptance. The root inspects the diff and verification evidence, resolves blocking findings, and decides acceptance. Root verification focuses on acceptance criteria, high-risk conclusions, and conflicting evidence, and does not repeat a completed check without a new change, failure, or specific concern.
- Preserve user-owned dirty files. Implementers do not stage or commit. The root stages exact task paths and commits only when the user authorizes it and the change forms one coherent theme.

请在这台电脑上部署一套 GPT-6.1 Sol 根代理的全局 Codex 子代理配置。只修改当前用户的 Codex Home 配置，不修改任何项目文件，不暂存、不提交、不推送。

目标行为：
1. 根代理使用 gpt-6.1-sol，默认 effort 为 medium（难题由用户用 /model 切到 xhigh），是唯一协调者、整合者和最终验收者，默认自己完成任务。
2. 只在四种理由下派发：可并行的独立工作、根代理不该装进上下文的大块内容、触发条件要求的独立验证、用户明确要求。git 操作、单条命令、文档与报告、配置修改、设备操作和约三个文件以内的明显修复不派发。
3. 派发按级别和积分权重计预算（gpt-6-luna 0.08、gpt-6.1-sol 1、gpt-6-sol 1.6、gpt-6-astra 8），L2 及以上在第一次派发前报告账本。
3a. implementer 和 qa 用 gpt-6-sol，reviewer 用 gpt-6.1-sol，二者互为预授权后备；子代理满载或断流时告知用户并在后备模型上重派一次，再失败则按降级阶梯处理。
4. 每次派发都写 agent_type（recon、implementer、qa、reviewer、astra_reviewer 之一）、对应模型、允许范围内的 reasoning_effort，以及 fork_turns = "none"。
5. 默认验证由根代理检查 diff 并运行针对性检查；高风险或跨模块改动加 reviewer，需要长时、并行或设备证据时加 qa；astra_reviewer 每个任务最多一次，只在 L3 及以上的具体高风险问题上串行使用。
6. 子代理不得继续委派、扩大范围、暂存、提交、推送、发布或修改规划和 memory 文件。
7. 写作使用精确动词，限制副词和程度词；用可观察的动作、细节和后果传达情绪与方式。

执行边界：
- 先使用当前安装的官方 Codex 文档核对自定义 Agent、AGENTS.md、config.toml 和 reasoning effort 的格式。
- 核对目标账号和客户端是否提供 gpt-6.1-sol、gpt-6-sol、gpt-6-astra、gpt-6-luna；文档列出模型不等于当前账号可用。缺少某个模型时报告阻塞，不换成其他模型。
- 运行 codex --version，记录当前版本，不要擅自升级。检查 CODEX_HOME；未设置时使用平台默认的 ~/.codex。
- 解析配置后只输出本次需要的非敏感白名单字段，如模型、effort、sandbox、审批策略和线程上限。不要打印完整 config.toml，也不要先输出再脱敏；MCP args、env、headers 和进程命令行默认只报告是否存在。
- 保留所有现有配置和 AGENTS.md 内容，只做定点合并。记录每个相关键、章节和 Agent 文件部署前的状态，仅在本机保存恢复材料。
- 若存在旧版 sol-implementer、sol-reviewer、terra-qa、luna-recon、luna-recon-max 文件且属于本文旧版，备份后删除；若同名文件属于其他用途，保留并报告冲突。
- 检查实际生效的全局指令文件、项目到工作目录的覆盖链和当前模型选择；AGENTS.override.md 存在时不要只更新被它遮蔽的 AGENTS.md。
- 使用结构化补丁编辑文件，不要用会整体覆盖文件的重定向命令。修改磁盘配置不证明现有任务已重新加载，必须在新进程中核对。未经授权不得提高线程上限。

步骤 A：在 ~/.codex/config.toml 根级定点更新 model = "gpt-6.1-sol"、model_reasoning_effort = "medium"、model_verbosity = "low"；确保只有一个 [agents] 表并合并 enabled = true、max_concurrent_threads_per_session = 6、default_subagent_model = "gpt-6-sol"、default_subagent_reasoning_effort = "high"、interrupt_message = true，遗留 max_threads 记录后删除。

步骤 B：仅限 Windows。在 PowerShell 中运行 codex -c windows.sandbox=mxc sandbox --include-managed-config --permission-profile :workspace -- cmd.exe /d /c echo MXC_OK。输出 MXC_OK 且退出码为 0 时把 [windows] sandbox 设为 "mxc"；否则保留原值并报告错误。

步骤 C：在实际生效的全局指令文件中合并附件里的 "## Writing Style"、"## Execution and Verification"、"## Codex Subagent Dispatch"，各保留一节。

步骤 D：按附件创建五个 Agent 文件，并按上面的规则处理旧版文件。

步骤 E：静态验证。用 TOML 解析器检查主配置和五个 Agent 文件，核对 name、description、model、model_reasoning_effort、sandbox_mode 和 developer_instructions；运行 codex doctor，确认 config.toml parse ok、没有 "is ignored" 提示，Windows 上 sandbox backend 为 mxc；确认三节规则各只有一节；枚举实际加载的指令文件，检查是否超过 project_doc_max_bytes（默认 32768 字节）。

步骤 F：只读烟测。在已知项目目录运行一次 codex exec --sandbox read-only -c approval_policy=never --model gpt-6.1-sol -c model_reasoning_effort=low，要求根代理按用户明确要求派发一个 recon（gpt-6-luna、low、fork_turns none）和一个 qa（gpt-6.1-sol、low、fork_turns none），各自只读取 package.json 或另一个已知文件中的一个已知字段。qa 的子线程模型应为 gpt-6.1-sol，证明不固定模型的角色会采用派发值。完成后从 ~/.codex/sessions 中找到子线程 rollout，读取 session_meta 的 agent_role 与 parent_thread_id、turn_context 的 model、effort 和 sandbox_policy。比较烟测前后的 git status 和 diff。

步骤 G：最终报告。报告 Codex 版本和 Codex Home；修改、创建和删除的文件；合并的键和章节；解析命令与结果；doctor 的配置、沙箱结果；烟测子线程的 agent_role、model、effort、sandbox；恢复材料位置；任何未验证项。确认没有修改、暂存、提交或推送项目文件。任何未完成项都不能写成全部部署成功。

完成前不要提交任何 Git 仓库，也不要更新 memory。

附件：

这是只读配置验收任务，不要修改任何文件，不要派发子代理。

请报告：
1. 当前 Codex 版本和工作目录。
2. 本会话加载了哪些全局和项目 AGENTS.md 指令来源。
3. 是否存在 Writing Style、Execution and Verification、Codex Subagent Dispatch 三节规则，以及 Dispatch 一节里的不派发清单、级别表和角色表。
4. 当前可用的自定义 Agent 名称。
5. 根代理和每个 Agent 的配置值：model、model_reasoning_effort（未固定时写明由派发给出）和 sandbox_mode，并说明覆盖来源。
6. max_concurrent_threads_per_session 的文件值；说明它限制打开的子代理线程，不是同时执行数。
7. 本会话的实际权限模式，并说明在该模式下只读角色是否真正只读。
8. 是否存在 AGENTS.override.md、项目配置覆盖、未知字段、重复 TOML table 或解析错误。

解析配置后只输出上述验收需要的非敏感白名单字段；不要输出密钥、token、HTTP header、MCP secret 或完整 config.toml，也不要先输出再脱敏。将"从配置文件读取到的值"和"运行时实际可观察到的值"分开报告。

这是只读 subagent 烟测，也是派发子代理的明确要求。先确认本会话以只读权限运行；否则停止并报告需要调整的运行设置。

派发且只派发一个子代理：agent_type = "recon"，model = "gpt-6-luna"，reasoning_effort = "low"，fork_turns = "none"。任务：报告 `<目标文件>` 中 `<目标字段或符号>` 的值和行号。

以当前会话工具 schema 为准；缺少字段时报告限制，不虚构参数。不要修改文件，不要运行构建，不要做额外仓库扫描。等待子代理返回，然后报告：agent_type、请求的模型和 effort、可见的解析后模型和 effort（不可见则说明）、文件与行号证据，以及相对于烟测前 git status 和 diff 的变化。

请为 `<项目路径>` 设计并创建或更新项目根目录 AGENTS.md。

执行边界：
- 先只读检查项目结构、构建文件、现有文档、真实测试命令和当前 Git 状态。
- 保留已有 AGENTS.md 内容，只做必要的项目级合并。
- 不复制全局"Codex Subagent Dispatch"全文；写明本项目继承全局调度规范，只写项目特有规则。
- 不修改生产代码或测试代码；不暂存、不提交、不推送。这个任务属于 L0，不派发子代理。
- 不写猜测性的构建命令、模块结构、依赖版本或测试数量。
- 发现信息不确定时列出未知项和可验证证据，不加入 fallback 或宽泛规则。

AGENTS.md 至少应覆盖：
1. 项目简介和真实技术栈。
2. 当前模块或目录结构。
3. 架构边界与禁止事项。
4. 安全、凭据和外部系统约束。
5. 真实可运行的构建、测试、lint 和格式化命令。
6. 针对 UI、移动端、后端、数据库或基础设施的验证要求。
7. Git、脏工作区、暂存、提交和发布纪律。
8. 本项目的高风险区域（决定何时加 reviewer 或 Astra 闸门）和派发例外；没有例外时写明继承全局规则。
9. 指令优先级和适用范围。

完成后：
- 展示 AGENTS.md 的变更摘要。
- 报告使用了哪些来源验证每条关键事实。
- 按目标工作目录检查实际加载的完整指令链，包括 override、嵌套目录指令和合并分隔符，是否超过 project_doc_max_bytes（默认 32768 字节）。
- 给出一个新会话只读验证命令。

修复 `<报错或问题>`，自己改并运行针对性检查，不要派发子代理。完成后 commit & push。

实现 `<具体功能>`，遵循已加载的 Codex Subagent Dispatch 和项目 AGENTS.md。先判定级别并在派发前报告账本；实现交给 implementer，根代理检查 diff 和针对性验证。涉及高风险区域时加 reviewer，需要设备或长时测试证据时加 qa。保留用户已有修改，不扩大范围，不提交。

只需要 review，不修改任何代码或文档。根代理先自己审查；只有涉及高风险区域时才派发 reviewer，并要求它尝试驳倒改动。按严重性返回有文件和行号依据的 findings；没有发现时说明剩余验证缺口。

对 `<问题>` 做证据驱动的深度调查。根代理先锁定具体证据缺口；只有存在可并行、互不依赖的窄问题时才派发 recon，每个都显式写 agent_type、model、reasoning_effort 和 fork_turns = "none"。先给出最小反例、真实执行路径和未解决未知项，不实施修复。

/goal 完成 `<结果>`。约束：遵循已加载的 Codex Subagent Dispatch；级别 L<n>，派发前报告账本；只对具体发现做修复和重新验证。验证：`<命令>` 通过；界面类结果在 `<里程碑>` 给我截图确认。检查点：每完成 `<里程碑>` 写一行进度并停下汇报。遇到需要我授权的步骤时停止并报告该步骤。最终报告证据、改动文件、失败的检查、剩余风险和未用预算。不要暂存、提交或推送。

User request
  ↓
Root (gpt-6.1-sol) classifies the level
  ├─ L0: no-spawn list or a small fix → root does it and runs the targeted check → done
  └─ L1+: report the ledger at L2+, name a reason for each spawn
        ↓
     Optional recon for a specific evidence gap (Luna)
        ↓
     implementer (gpt-6-sol) for a large or isolated change; visible checkpoint first for UI work
        ↓
     Root inspects the diff and runs targeted checks
        ↓
     reviewer (gpt-6.1-sol) for high-risk or cross-module diffs; qa (gpt-6-sol) for long, parallel, or device evidence
        ↓
     On capacity or stream failure: tell the user, respawn once on the fallback model, then the degradation ladder
        ↓
     astra_reviewer once, at L3+, for one named high-risk issue
        ↓
     Exact repair through followup_task; a second review uses a fresh reviewer
        ↓
     Root accepts against the criteria
        ↓
     Commit or push only when explicitly authorized
