feat(tool): add persistent pause and resume support for tool calls - #395

Document or honor RequestNextOptions in onAfterRequest.

requestNext here accepts RequestNextOptions but discards it. AfterRequestContext.requestNext is typed as (options?: RequestNextOptions) => void, and RequestNextOptions.resume is documented as marking the follow-up turn as a resume that triggers onTurnResume. A plugin that passes { resume: true } from onAfterRequest gets no effect and no warning. Only dispatchCommand honors the option.

The follow-up in postRequest continues the same turn through executeRequest, so onTurnResume does not apply. State that restriction in the RequestNextOptions documentation so plugin authors know the option is only meaningful for command-driven continuation.

onAfterRequest requestNext implementation and RequestNextOptions documentation:
either honor the supplied options or explicitly document that resume is
unsupported for this postRequest/executeRequest continuation and only applies to
command-driven continuation through dispatchCommand. Ensure the typed API’s
behavior and documentation match so passing resume does not silently imply
onTurnResume.

Bound the snapshot store with a retention rule.

saveTurnSnapshot appends a new entry for every distinct turnId and never prunes. clearTurnSnapshot only runs when a turn completes, resumes, or is aborted in the same session. If a user leaves a paused turn and later starts a conversation whose messages no longer match that snapshot, findRestoredTurn skips it and nothing deletes it. The entry then stays in localStorage forever. When the store grows large enough to exceed the quota, writeStore swallows the error and new paused turns stop persisting silently.

pausedAt is already persisted but never read. Use it to drop expired snapshots and cap the list size on load and on save.

♻️ Proposed retention rule

 const TURN_STATE_VERSION = 1
+const TURN_STATE_MAX_AGE = 7 * 24 * 60 * 60 * 1000
+const TURN_STATE_MAX_ENTRIES = 20
+
+const pruneTurns = (turns: PersistedTurnSnapshot[]): PersistedTurnSnapshot[] => {
+  const now = Date.now()
+  return turns
+    .filter((turn) => now - turn.pausedAt < TURN_STATE_MAX_AGE)
+    .sort((a, b) => b.pausedAt - a.pausedAt)
+    .slice(0, TURN_STATE_MAX_ENTRIES)
+}

Then apply pruneTurns to parseStore's returned turns.

Derive the resource tool names from the schema source.

collectPendingSkillNames hardcodes 'list_skill_files' and 'read_skill_file'. The same names are defined by the resource tool schemas that createSkillResourceRuntimeTools builds in packages/kit/src/skills/capabilities/resources.ts. If a schema name changes there, this filter stops matching. Restoration then silently skips the pending skill, and the resumed read_skill_file call resolves against a rebuilt tool set that lacks the skill. No error surfaces.

Export the resource tool names from the resources module and compare against them here.

filtering remains synchronized when schema names change.

Prune stale snapshots when saving.

saveTurnSnapshot appends a new entry for every paused turn and never removes old ones. Snapshots are deleted only by clearTurnSnapshot, which the tool plugin calls on resume, turn end, and abort. A paused turn that the user abandons, or whose engine is never recreated, leaves its entry in localStorage permanently.

This has a second effect on restoration. findPersistedPausedTurn in packages/kit/src/message/plugins/toolPlugin.ts returns a snapshot only when exactly one matches, so accumulated entries raise the chance of an ambiguous match and silent restore failure. pausedAt is stored but never read.

Drop entries older than a retention window, or cap the stored count, when writing.

♻️ Proposed change

+const TURN_STATE_MAX_AGE_MS = 7 * 24 * 60 * 60 * 1000
+
 export const saveTurnSnapshot = (snapshot: PersistedTurnSnapshot): void => {

   const turnStorage = parsePersistedTurnStorage(storedValue)
-  const existingIndex = turnStorage.turns.findIndex((turn) => turn.turnId === snapshot.turnId)
+  const now = Date.now()
+  turnStorage.turns = turnStorage.turns.filter(
+    (turn) => turn.turnId === snapshot.turnId || now - turn.pausedAt <= TURN_STATE_MAX_AGE_MS,
+  )
+  const existingIndex = turnStorage.turns.findIndex((turn) => turn.turnId === snapshot.turnId)

Scope the persisted tool-call scan to the current turn.

persistPausedTurnState collects awaiting-approval tool-call IDs from state.messages, which is the whole conversation history. It then stores every collected ID under the current context.turnId.

If an earlier turn left an orphaned awaiting-approval tool call, its ID enters the new turn's snapshot. Restoration then goes wrong in two ways. findPersistedPausedTurn matches on any overlapping ID, and restorePersistedTurnMessages uses findIndex, so it slices from the first assistant message that holds a matching ID. That is the old assistant message, not the paused one, and the restored currentTurn then covers unrelated history under the new turnId.

Restrict the scan to context.currentTurn when it is populated.

♻️ Proposed change

     const state = context.getState()
+    const scopedMessages = context.currentTurn.length > 0 ? context.currentTurn : state.messages
     const toolCallIds = Array.from(
       new Set(
-        state.messages.flatMap((message) => {

Expose persistPausedTurn in the Vue tool plugin.

The core tool plugin accepts persistPausedTurn and defaults it to true, so it writes paused-turn snapshots to localStorage. This Vue wrapper does not declare or forward the option. A caller that sets it lands in restOptions, and runtime.createCorePlugin(restOptions) copies only lifecycle hooks, so the value is dropped before createCoreToolPlugin runs.

Vue consumers therefore cannot disable persistence. The snapshot includes customContext, which plugins may populate with application data.

     toolCallFailedContent?: string
+    /**
+     * 是否在浏览器 localStorage 中持久化暂停的工具回合。默认：true。

The onAfterRequest resume flag is declared but not implemented. Both public plugin surfaces now type requestNext as (resume?: boolean) => void, but the engine's postRequest binds it as (_resume?: boolean) => { shouldRequest = true } and then calls executeRequest directly. Only dispatchCommand forwards the flag to runTurnLifecycle({ resume }). A plugin that calls requestNext(true) from onAfterRequest gets a non-resume continuation, and onResumed does not run.

• packages/kit/src/message/types.ts#L187-L187: implement the flag in postRequest, or document that resume applies only to command handlers.
• packages/kit/src/vue/message/types.ts#L207-L207: apply the same decision here, because useMessage forwards the core callback unchanged.
