The doctor "can find npm/pi" checks wrap the version command in a POSIX
subshell, `(cmd --version 2>&1 || true)`. Fish treats `( ... )` as command
substitution syntax and forbids it in command position, so every fish user saw
false-negative failures:
fish: command substitutions not allowed in command position
command -v npm && (npm --version 2>&1 || true)
Branch on the detected service shell and emit fish's `begin; ...; end`
grouping for fish, mirroring the existing fish-aware quoting in
serviceShellQuote. Bash and zsh keep the POSIX subshell.
Also guard the `main()` invocation with an ESM main-module check so the CLI
helpers can be imported by tests without side effects, and add a regression
test covering the bash, zsh, and fish command shapes.
Split subsession inspection into two tools: check_subsession gives a quick
glance (status + latest assistant output), while read_subsession reads through
a child's transcript with role/content filters, full-content substring search
(including tool-call args), optional per-value maxChars truncation that flags
clipped parts, includeToolArgs, and pagination.
Filtering and search run on full untruncated content; truncation is an explicit,
caller-owned final projection (no default) so a narrow read never silently hides
a match. Empty page-windows are distinguished from zero-match results.
Add the Relay method skill (execute a long plan as a chain of independent
sessions handing off via spawn_session) under a top-level skills/ folder that
follows the open agent-skills convention, installable with the skills CLI.
Also clarify the changeset-changelog skill: no changeset is needed for changes
outside the npm release allowlist (package.json files), such as repo-only
agent skills under .agents/ and skills/.
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.
Attachments can be pasted, dropped, or uploaded, so 'paste' was too
narrow. Rename the default folder and filename prefix accordingly and
update the changeset reference.
The stream catch-up mode was represented by two fields that could drift:
the private catchupStreamSessionId guard (which suppresses live transcript
events while the in-flight message prefix is missing) and the public
isReceivingPartialStream flag (which drives the badge). The socket reconnect
path (refreshSelectedSession) set the flag from status without updating the
guard, so a later idle status.update was skipped by the guard check and the
badge never cleared.
Route every mutation of the mode through a single setStreamCatchup helper so
the guard and badge can't disagree, and clear the mode on any non-streaming
status for the selected session.
