When `initialize.params.capabilities.experimentalApi = true`, the payload can also include experimental `additionalPermissions` describing requested per-command sandbox access. Any filesystem paths inside `additionalPermissions` are absolute on the wire.

8675. `item/completed` returns the final `commandExecution` item with `status: completed | failed | declined`.
868
869When `networkApprovalContext` is present, the prompt is for managed network access (not a general shell-command approval). The current v2 schema exposes the target `host` and `protocol`; clients should render a network-specific prompt and not rely on `command` being a user-meaningful shell command preview.
870
871Codex deduplicates concurrent network approval prompts by destination (`host`, protocol, and port). The app-server may therefore send one prompt that unblocks multiple queued requests to the same destination, while different ports on the same host are treated separately.

883### `tool/requestUserInput`
884
885When the client responds to `item/tool/requestUserInput`, app-server emits `serverRequest/resolved` with `{ threadId, requestId }`. If the pending request is cleared by turn start, turn completion, or turn interruption before the client answers, the server emits the same notification for that cleanup.
886
887### Dynamic tool calls (experimental)
888
889`dynamicTools` on `thread/start` and the corresponding `item/tool/call` request or response flow are experimental APIs.
890
891When a dynamic tool is invoked during a turn, app-server emits:
892
8931. `item/started` with `item.type = "dynamicToolCall"`, `status = "inProgress"`, plus `tool` and `arguments`.
8942. `item/tool/call` as a server request to the client.
8953. The client response payload with returned content items.
8964. `item/completed` with `item.type = "dynamicToolCall"`, the final `status`, and any returned `contentItems` or `success` value.

769App (connector) tool calls can also require approval. When an app tool call has side effects, the server may elicit approval with `tool/requestUserInput` and options such as **Accept**, **Decline**, and **Cancel**. If the user declines or cancels, the related `mcpToolCall` item completes with an error instead of running the tool.900App (connector) tool calls can also require approval. When an app tool call has side effects, the server may elicit approval with `tool/requestUserInput` and options such as **Accept**, **Decline**, and **Cancel**. Destructive tool annotations always trigger approval even when the tool also advertises less-privileged hints. If the user declines or cancels, the related `mcpToolCall` item completes with an error instead of running the tool.

1080### Config RPC examples for app settings
1081
1082Use `config/read`, `config/value/write`, and `config/batchWrite` to inspect or update app controls in `config.toml`.
1083
1084Read the effective app config shape (including `_default` and per-tool overrides):
1085
1086```json
1087{ "method": "config/read", "id": 60, "params": { "includeLayers": false } }
1088{ "id": 60, "result": {
1089 "config": {
1090 "apps": {
1091 "_default": {
1092 "enabled": true,
1093 "destructive_enabled": true,
1094 "open_world_enabled": true
1095 },
1096 "google_drive": {
1097 "enabled": true,
1098 "destructive_enabled": false,
1099 "default_tools_approval_mode": "prompt",
1100 "tools": {
1101 "files/delete": { "enabled": false, "approval_mode": "approve" }
1102 }
1103 }
1104 }
1105 }
1106} }
1107```
1108
1109Update a single app setting:
1110
1111```json
1112{
1113 "method": "config/value/write",
1114 "id": 61,
1115 "params": {
1116 "keyPath": "apps.google_drive.default_tools_approval_mode",
1117 "value": "prompt",
1118 "mergeStrategy": "replace"
1119 }
1120}
1121```
1122
1123Apply multiple app edits atomically:
1124
1125```json
1126{
1127 "method": "config/batchWrite",
1128 "id": 62,
1129 "params": {
1130 "edits": [
1131 {
1132 "keyPath": "apps._default.destructive_enabled",
1133 "value": false,
1134 "mergeStrategy": "upsert"
1135 },
1136 {
1137 "keyPath": "apps.google_drive.tools.files/delete.approval_mode",
1138 "value": "approve",
1139 "mergeStrategy": "upsert"
1140 }
1141 ]
1142 }
1143}
1144```
1145
1146### Detect and import external agent config
1147
1148Use `externalAgentConfig/detect` to discover migratable external-agent artifacts, then pass the selected entries to `externalAgentConfig/import`.
1149
1150Detection example:
1151
1152```json
1153{ "method": "externalAgentConfig/detect", "id": 63, "params": {
1154 "includeHome": true,
1155 "cwds": ["/Users/me/project"]
1156} }
1157{ "id": 63, "result": {
1158 "items": [
1159 {
1160 "itemType": "AGENTS_MD",
1161 "description": "Import /Users/me/project/CLAUDE.md to /Users/me/project/AGENTS.md.",
1162 "cwd": "/Users/me/project"
1163 },
1164 {
1165 "itemType": "SKILLS",
1166 "description": "Copy skill folders from /Users/me/.claude/skills to /Users/me/.agents/skills.",
1167 "cwd": null
1168 }
1169 ]
1170} }
1171```
1172
1173Import example:
1174
1175```json
1176{ "method": "externalAgentConfig/import", "id": 64, "params": {
1177 "migrationItems": [
1178 {
1179 "itemType": "AGENTS_MD",
1180 "description": "Import /Users/me/project/CLAUDE.md to /Users/me/project/AGENTS.md.",
1181 "cwd": "/Users/me/project"
1182 }
1183 ]
1184} }
1185{ "id": 64, "result": {} }
1186```
1187
1188Supported `itemType` values are `AGENTS_MD`, `CONFIG`, `SKILLS`, and `MCP_SERVER_CONFIG`. Detection returns only items that still have work to do. For example, AGENTS migration is skipped when `AGENTS.md` already exists and is non-empty, and skill imports do not overwrite existing skill directories.
