Please list all the tools you currently have, without explanation.

Output includes:
functions.exec

1. Ask:

Please use functions.exec to run:
pwd

Expected:
functions.exec is invoked.

Actual:
"The current session does not actually expose a callable functions.exec tool, so pwd cannot be executed."

Additional:

• MCP starts successfully.
• computer-use no longer reports startup errors.
• Tool registry lists exec, but runtime does not expose it to the agent.

Codex 桌面版更新后工作区工具无法挂载 - 修复指南
问题现象
Codex 桌面版（ChatGPT.app 内嵌版）更新后，工作区工具（workspace tools）始终无法挂载，文件系统操作、文档编辑等工具不可用。

根因
更新后 ~/.codex/config.toml 中 profile 级别的 sandbox_mode = "workspace-write" 与需求不兼容。该模式下沙箱根目录数量为 0（writableRootCount: 0），导致工作区工具无法挂载。

即使顶层设置了 sandbox_mode = "danger-full-access"，profile 级别配置也会覆盖顶层设置，手动改顶层无效。

解决方案
步骤一：编辑配置文件
bash
vim ~/.codex/config.toml
找到 [profiles.<你的profile名>] 段，删除或注释掉：

toml
sandbox_mode = "workspace-write"
确保顶层有（或添加）：

toml
sandbox_mode = "danger-full-access"
示例 diff：

diff
[profiles.tokenpower]
model_provider = "tokenpower"
model = "gpt-5.5"
model_catalog_json = "cc-switch-model-catalog.json"
model_context_window = 1000000
approval_policy = "on-request"
-sandbox_mode = "workspace-write"
步骤二：重启 Codex 桌面版
注意：修改配置后必须完全退出 Codex 桌面版再重新打开，仅新建会话不会重载配置。

验证方式
打开 Codex 桌面版日志（~/Library/Logs/com.openai.codex/），查找最新日志中的 responseSandboxPolicy：

responseSandboxPolicy={"type":"dangerFullAccess",...}
确认 type 为 dangerFullAccess 即生效。

环境信息
Codex 桌面版版本：v26.707.31428（ChatGPT.app 内嵌）
Runtime 版本：v26.709.11516
CLI 版本：0.144.1
系统：macOS 26.5.1（Apple Silicon）
