Add spawn_subsession / list_subsessions / read_subsession tools that let an
agent start child sessions it stays attached to: the child records its parent
in the session tree, the parent is notified (as a system-authored custom
message that wakes an idle parent and queues behind in-flight work) when the
child stops working, and the parent can inspect children's status and result.
Gated behind a beta flag, off by default, mirroring spawnSessions: enable via
PI_WEB_SUBSESSIONS, the subsessions config key, or the Settings toggle. Also
requires spawnSessions.
Also fix the release skill so the version step resyncs package-lock.json
(npm install --package-lock-only) and the commit step refuses a release where
package.json and package-lock.json versions disagree.
Add a project-scoped spawn_session tool so agents can dispatch new,
independent sessions (ralph loops, long-plan chaining). Spawned sessions
are constrained to a workspace/worktree of the same registered project,
appear in the session list immediately via a new session.created event,
and the capability is on by default with a Settings -> Session daemon
toggle (spawnSessions / PI_WEB_SPAWN_SESSIONS).
Note: adds a session daemon code path, so pi-web-sessiond.service must be
restarted manually for the server side to take effect.
Support pasting (Ctrl/Cmd+V), drag-and-drop, and an Attach button to add
PNG/JPEG/GIF/WebP images to a message, with thumbnail previews and
multi-image support.
Attachments are delivered to the session using pi's native ImageContent
format and are run through pi's own resizeImage so they match pi's inline
image limits exactly. Image content now renders inline in the transcript.
A per-message delivery toggle also lets users save attachments into the
workspace `.pi-web/paste` folder and reference them so the agent reads
them with its own tools.
The accepted HTTP upload size is configurable via PI_WEB_MAX_UPLOAD_BYTES
or the maxUploadBytes config value (default 64 MB).
