* feat(plugins): give plugins the agent's sidebar indicator and background flag Plugin UI re-derived agent state from status and attention fields and could not see background work, so it showed agents as done while a shell they left running was still live. Agent snapshots now carry the sidebar's own bucket as indicator/indicatorLabel, computed by the same function the sidebar uses so the two cannot drift. Lifecycle hooks and the agent.open.before request now carry `background`, so a hook can skip a hidden helper agent without a lookup. A hook cannot change it; an omitted value means unchanged, like metadata. `finished` attention still means the turn finished; background work is the indicator's concern. * fix(plugins): keep session-open hooks that omit background typechecking A hook that returns its own object instead of spreading the request has no background field; the result type now treats it as optional, like metadata, matching the runtime where an omitted value means unchanged. * refactor(plugins): give agent snapshots the background work count instead of an indicator * fix(plugins): keep legacy session-open hooks that omit background typechecking
Lifecycle actions
Small callbacks using the existing SDK:
- Send
Try again.when the latest output containsout of credits, except to background agents. - Decline a shell request matching
rm -rf; approve exactlygit status; leave other requests alone. - Inject
PASEO_HOOK_CREATE_EXAMPLE=createdon creation andPASEO_HOOK_OPEN_EXAMPLE=openedon each session opening. - Change requested Codex agents to Claude Haiku before creation.
- Create a worktree when a directory creation request is titled
Isolated lifecycle example.
This is a demonstration plugin: installing it enables all these behaviors on its host. Install it
alongside lifecycle-logger on a test daemon with plugins enabled:
paseo plugin install /absolute/path/to/plugin-examples/lifecycle-actions
paseo plugin install /absolute/path/to/plugin-examples/lifecycle-logger
paseo plugin logs lifecycle-logger
Outside the Paseo repository, server/inspect.ts needs @getpaseo/protocol installed for its
type imports. Add it to your plugin development dependencies at the same version as
@getpaseo/plugin before installing this example.
Copy the callbacks you need into your own plugin. The follow-up example sends a new message; it does not replay attachments or undo previous tool effects. If the provider keeps returning the matching phrase, it keeps sending follow-ups. Add limits or delay in your plugin when your workflow needs them. The command regex illustrates a policy; it does not parse shell syntax or cover every deletion command.
server/inspect.ts joins provider text chunks and excludes earlier turns and the current user prompt
from the phrase match. The failing-first regression test records the split text observed with a real
Claude agent.
See agent configuration for a focused example that injects MCP servers and changes Codex sandbox and approval options while preserving other settings.
See the lifecycle reference for the API.
