* feat(subagents): archive finished children and show native names
Keep native provider sessions intact while letting users clear completed children from the track. Persist dismissed provider child IDs so history replay does not restore them.
* fix(subagents): cover persistence and naming edge cases
* fix(subagents): preserve active descendants and native names
* fix(subagents): retain dismissed timelines and trim paths
* fix(subagents): retain history across hydration
* test(subagents): expect normalized native descriptions
* fix(subagents): separate hidden rows from retained history
* fix(subagents): preserve restored hidden tabs safely
* fix(subagents): integrate archive with run state
* test(codex): expect normalized child name
* fix(subagents): retain dismissed tabs on reload
* fix(subagents): hide finished native agents locally
Keep the header action presentation-only so it does not mutate agent lifecycle or expand the runtime protocol.
* fix(subagents): humanize native agent names
* fix(subagents): preserve names in Codex history
* fix(subagents): retain hidden rows across reloads
* fix(server): prevent hidden Codex subagents and stuck turns
Codex can announce native children only through its mirrored lifecycle stream, while rejected interrupts previously looked like successful local cancellation. Preserve those child announcements and keep manager state active until the provider acknowledges cancellation.
* fix(server): block actions after rejected cancellation
A provider can accept a turn before publishing the turn ID needed to interrupt it. Keep that interval non-cancelable, and prevent reload, replacement, or rewind from proceeding without an acknowledged cancellation.
* fix(server): surface rejected agent cancellations
Replacement prompts and Stop requests could appear accepted after the provider kept ownership of the active turn. Complete replacement cancellation before detaching the stream, and return cancellation failures through the client response.
* fix(server): handle turn completion during cancellation
* fix: finish cancellation lifecycle handling
* fix(server): close remaining cancellation races
* fix(server): settle autonomous cancellations
* fix: honor cancellation failures at call sites
* refactor(server): centralize agent run state
* fix(server): keep pending runs isolated from stale events
* fix: surface remaining cancellation failures
* fix(server): narrow cancellation error handling
* fix(workspaces): show provider subagent activity
Provider subagent lifecycle lives outside managed agent snapshots, so workspace aggregation dropped it after the parent turn finished. Count running provider subagents against the delegation root and emit workspace updates when their status changes.
* fix(workspaces): surface cross-workspace subagents
Require relationship and workspace on create_agent, and reuse the same worktree target union for create_worktree. Agent-scoped prompt follow-ups now default to background finish notifications so callers can continue without polling.
Multiple workspaces can share one checkout directory. Agent and terminal
status, sidebar tabs, and ownership now attribute strictly by workspace ID,
so a running or blocked agent in one workspace no longer shows up on its
same-directory siblings.
A one-time startup migration backfills workspace IDs onto legacy agents, and
every agent and terminal is created with one thereafter. Directory lookups
remain only for genuinely folder-derived git facts (branch, diff) and the
archive-by-path adapter.
* Make workspace IDs opaque, independent of the filesystem path
Workspace IDs were the resolved checkout/worktree path, so code could
treat an ID as a path: prefix matching, deriving directories from it,
falling back to a path when a lookup missed. IDs are now opaque -
compared only by exact equality and never used as a path. Anything
path-shaped resolves the workspace record first and reads its cwd.
New workspaces get a generated `wks_` ID; existing path-shaped IDs are
read from disk and never regenerated, so there is no migration and no
change to the wire or persisted schemas. Groundwork for running
multiple workspaces in a single directory.
* Keep attachment scope key stable and align refetch test
The attachment scope key keeps `workspace=` instead of `wsid=` so existing
persisted drafts are not orphaned; the rename was cosmetic. The SDK refetch
test no longer asserts a filter, matching refetch fetching one page and
selecting by id client-side.
* Fix live agent updates in directories without a registered workspace
The opaque-ID work removed buildProjectPlacementForCwd's directory
fallback, so an agent running in a folder with no registered workspace
(e.g. a fresh non-git dir) produced a null placement. forwardAgentUpdate
then threw "Workspace not found", the error was swallowed by its catch,
and no agent_update was emitted — live model/thinking switches and status
updates silently stopped. Caught by the live-preferences e2e suite.
The fallback builds a directory-scoped project placement keyed by the
path. That key is a project grouping key (non-git projects group by
path), not a workspace id, so it stays within the opaque-id rule.
* Always run server worktree archive, even without a resolved workspace
Archiving bailed out entirely when the workspace was not found in the
client store, so a race or stale state could make "archive" do nothing
server-side with only a console.warn. The server archive is keyed by
worktreePath, which is always available, so it now runs regardless; only
the optimistic client-side updates (keyed by workspace id) are gated on
the workspace being resolved.
* Expect a directory-scoped placement for unregistered agent dirs
This unit test asserted the no-placement behavior reverted in the live
agent-update fix, which had broken live model/thinking switching. Update
it to expect the directory-scoped placement now emitted for an agent in a
directory with no registered workspace.
* Fix opaque workspace routing in app E2E
* Preserve workspace IDs during partial bootstrap
* Fix archive flows for opaque workspace IDs
* Stop treating opaque workspace IDs as filesystem paths
Workspace IDs are opaque (wks_<hex>), but several call sites still passed
the id where a directory was expected, which broke those flows for opaque
IDs. The branch switcher sent the id as a cwd to branch/stash/checkout git
operations, and server archive/reconcile cleanup keyed git-watch and
subscription teardown by id, leaking that state.
Git and filesystem operations now take the workspace directory; the opaque
id is used only for identity and cache keys. Archive/reconcile cleanup
routes through a single teardownArchivedWorkspace helper that keeps the key
split explicit: runtime store by id, git watch and subscription by cwd.
Path-derived grouping keys are renamed to directory keys, and the helpers
are split into workspace-identity and workspace-directory so the id-vs-path
boundary is obvious.
* Surface paseo subagents in a collapsible section above the composer
Subagents no longer auto-open as tabs. Each parent agent's pane shows
a compact tab attached to the top of the composer, listing its direct
children with name and status; clicking a row opens or focuses the
subagent's tab. The section is provider-neutral so Claude Code Task
and Codex subagent sources can feed the same UI later. Reconciliation
now separates pruning (`activeAgentIds`) from auto-opening
(`autoOpenAgentIds`) so manually opened subagent tabs survive.
* Tighten subagents composer code from review
Collapse duplicate helper in workspace reconciliation, swap a hand-rolled
shallow comparator for fast-deep-equal (matching repo convention), drop
an unused React default import and a single-use formatCount helper, and
extract a shared PaneOverrides type in the agent-panel test.
* Fix oxlint failures in subagents code
Switch type aliases to interfaces, hoist inline JSX styles/handlers in
SubagentsSection to satisfy react-perf rules, and lift the test
makeAgent helpers onto AGENT_DEFAULTS so their cyclomatic complexity
drops below the configured cap.
* Add missing unistyles mock exports after rebase
After rebasing onto main, SubagentsSection now imports both
useUnistyles and (transitively, via WorkspaceTabIcon) withUnistyles.
Two test mocks needed updating to expose them.
Test drift fix: the implementation contract is correct; the local
react-native-unistyles mocks were stale.
* Tuck subagents tab under the composer
Subagents tab now grows visually from beneath the composer's rounded
top edge: the surface overlaps the composer by the corner radius so
the rounded curve nests into the tab. Composer's top padding is
removed so the tab sits flush against the input box with no
click-dead gutter. The tab is full-width in both states, the header
label drops the medium weight to follow design-system §3 (content
text inside a surface is normal), and hover covers the entire
visible tab when collapsed but stays scoped to the header row when
expanded.
* Decouple subagent close-tab from archive
Closing a subagent's tab no longer archives the agent — the tab is
removed from the per-client layout, the agent stays in the parent's
track until explicitly archived. Track rows gain an archive button (X)
to make the lifecycle gesture explicit. AgentManager.archiveAgent now
cascades to children carrying the paseo.parent-agent-id label so
subagent fleets don't outlive their orchestrator.
Trade-offs documented in docs/agent-lifecycle.md, including the known
limitation that handoff agents launched via the same MCP path get
cascade-archived alongside true subagents until a richer relation
model lands.
* Stabilize subagent archive button hover
Apply the sidebar workspace row pattern to fix two issues with the
new archive button: the row no longer drops hover when the pointer
moves onto the button, and the button slot reserves layout space
when invisible so adding/removing it doesn't shift the row.
The wrapper View tracks hover via onPointerEnter/onPointerLeave
(workspace rows do the same), and the slot stays mounted with
opacity 0 + pointerEvents="none" when the button is hidden. Also
swap the X icon for the Archive icon to match the gesture's intent.
* Match design language for subagent archive button
Hover state now changes the icon color from foregroundMuted to
foreground, matching the project-row trailing-action pattern in
sidebar-workspace-list.tsx. Drops the surface3 background hover
that didn't match the design language.
Adds a tooltip ("Archive subagent") on the trigger using the
canonical Tooltip + TooltipTrigger asChild pattern. Disabled when
the slot is hidden so it never appears unbidden.
* Slot subagents into one module + harden cascade
Reshape the subagents-in-composer feature so it lives behind one
module and integrates at a few explicit sites instead of being
smeared across generic files.
- Extract `PARENT_AGENT_ID_LABEL` to `packages/server/src/shared/agent-labels.ts`. Sweeps 16 literal sites across server, client, CLI, and tests.
- `packages/app/src/subagents/` is now a deep module: `index.ts` is the only React entry (`SubagentsSection`, `useArchiveSubagent`, `useSubagentsForParent`, `selectSubagentsForParent`, `resolveCloseAgentTabPolicy`, `shouldAutoOpenAgentTab`); `policies.ts` is a second designed entry for non-RN data consumers. Internal files renamed (`section.tsx`, `select.ts`, `close-tab-policy.ts`, `auto-open-tab-policy.ts`, `use-archive-subagent.ts`).
- Move the 22-line subagent archive flow out of `agent-panel.tsx` into `useArchiveSubagent`. Agent-panel becomes a one-line consumer.
- Move the close-tab subagent branch out of `workspace-screen.tsx` into `resolveCloseAgentTabPolicy` (discriminated union).
- Move the auto-open exclusion rule out of `workspace-agent-visibility.ts` into `shouldAutoOpenAgentTab`.
- Theme chevrons in `section.tsx` via `withUnistyles`; drop the forbidden `useUnistyles()` call from the hot path.
Server-side cascade hardening:
- Single write path: extract `markRecordArchived` and route both `archiveAgent` and the off-memory cascade branch through it. Off-memory cascaded children now notify subscribers (previously silent).
- Cascade no longer swallows child failures with `try/catch warn`. Failures propagate.
- Cascade test extended from 1 weak assertion to 5 contract tests: full archive shape (archivedAt, normalized lastStatus, requiresAttention=false), running child runtime stop, off-memory branch, subscriber notification for in-memory and off-memory children, partial-failure surfacing.
Net diff vs the start of this PR: -1037 / +444 lines. The feature now slots into the repo at four explicit sites: `agent-panel.tsx` (3 imports + a hook + the section), `workspace-screen.tsx` (one policy import), `workspace-agent-visibility.ts` (one predicate import), and `agent-manager.ts` (the cascade plus the shared label constant).
