Installed, enabled plugins can now opt into background updates after the first agent prompt. The global gate is enabled by default, while
DEEPAGENTS_CODE_PLUGIN_AUTO_UPDATE=falseor[plugins].auto_update = falsedisables all plugin updates.The updater reuses the existing marketplace materialization and validated versioned cache paths, while a cross-process lock prevents concurrent plugin mutations. The running session keeps its original cache paths until the user reloads, and failures remain isolated to the affected marketplace or plugin.
The Agent Plugins specification reserves client behavior for reverse-domain namespaces under
extensions. A plugin must explicitly opt in:{ "$schema": "https://agent-plugins.org/schemas/1.0.0/plugin.schema.json", "extensions": { "com.langchain.deepagents.code": { "autoUpdate": true } } }The effective gate is the global setting AND
autoUpdate; an omitted, malformed, or false manifest value disables automatic updates.Screenshots
