> <collaboration_mode># Collaboration Mode: Default

You are now in Default mode. Any previous instructions for other modes (e.g. Plan mode) are no longer active.

Your active mode changes only when new developer instructions with a different `<collaboration_mode>...</collaboration_mode>` change it; user requests or tool descriptions do not change mode by themselves. Known mode names are Default and Plan.

## request_user_input availability

The `request_user_input` tool is unavailable in Default mode. If you call it while in Default mode, it will return an error.

In Default mode, strongly prefer making reasonable assumptions and executing the user's request rather than stopping to ask questions. If you absolutely must ask a question because the answer cannot be discovered from local context and a reasonable assumption would be risky, ask the user directly with a concise plain-text question. Never write a multiple choice question as a textual assistant message.

I’m rebuilding the current reminder path from code, not the transcript. First I’m checking repo state, the reminder implementation, the scheduler/channel plumbing, and the iMessage transport so the gap is grounded in actual files.

I found the repo state and the earlier reminder work is still uncommitted only in its own files, not mixed with unrelated changes. Now I’m reading the exact reminder data path end to end: tool definition, CLI execution context, app reminder persistence/fire path, daemon output routing, and iMessage transport.

The tool side is confirmed: `example tool remind` now works through the same harness tool, and the standalone `remind` subcommand is gone. I’m reading the persistence and fire path next to see whether the reminder row carries any channel origin at all.
  [Bash: nl -ba AGENTS.md | sed -n '32,52p']

iMessage transport is there; I’m now verifying the exact handoff points. The key question is whether reminder creation preserves `Source`/`SourceMeta` the way channel executions already do, or whether that context gets dropped before persistence.
  [Bash: nl -ba example/cli/internal/daemon/channels/imessage.go | sed -n '150,390p']

The transport layer is intact. What I still need to prove is the omission: whether the harness context has any source/origin carrier today, and whether the app-side reminder insert accepts anything beyond `session_id` and `agent_id`.

The missing piece is now clear enough that I’m checking one last layer in the proxy: whether iMessage replies can already be sent back to 1:1 and group chats. If that’s present too, then the reminder work is purely origin capture plus dispatch, not channel infrastructure.
  [Bash: nl -ba example/proxy/src/channels/imessage/relay.ts | sed -n '120,170p']

  [Bash: rg -n "SCHEMA_VERSION" example/app/electron/services/metadata-db.service.js]

The last proof I need is the agent execution context itself. If the harness only injects session, execution, and user IDs, then reminder tools cannot know they originated from iMessage even though the daemon does.
  [Bash: nl -ba harness/agent/agent.go | sed -n '416,432p']

  [update_plan]

There’s one more subtle point I need to verify before I give you the implementation path: iMessage replies in the proxy currently key off the original `message_id`. If that context is only in memory, later reminders may need a slightly different dispatch path than ordinary immediate replies.
  [Bash: nl -ba example/proxy/src/channels/imessage/relay.ts | sed -n '1,120p']
  [Bash: rg -n "messageContexts|new Map|delete context|orphan_response|sendReply\(|sendGroupMessage\(|sendMessage\(" example/prox...]

  [Bash: rg -n "WithSource|source_meta|output_target|resume" example/cli/internal/cli/run.go example/cli/internal/daemon/executor.go...]

I found an extra constraint: the current iMessage reply path is only durable for about 10 minutes because the proxy stores reply context in memory per inbound message. I’m checking the provider constructor so I can tell you whether later reminders can reuse the existing path or need a new direct-send branch.
  [Bash: nl -ba example/proxy/src/channels/imessage/provider.ts | sed -n '1,130p']
  [Bash: nl -ba example/proxy/src/channels/imessage/index.ts | sed -n '1,40p']

  [Bash: rg -n "messageContexts.delete|10 \* 60 \* 1000|orphan_response" example/proxy/src/channels/imessage/relay.ts]

There’s an architectural constraint too: reminder firing is happening inside Electron, while channel delivery lives in the CLI daemon. I’m checking whether the app already has a daemon-facing API for outbound channel sends, or whether the clean solution is to move channel reminders onto the daemon/scheduler side.
  [Bash: rg -n "daemon|OutputRouter|schedule|scheduler|host bridge|bridge" example/app/electron/main.js example/app/electron/service...]

  [Bash: nl -ba example/cli/internal/daemon/scheduler.go | sed -n '1,120p']

I checked the app side and reminder firing stays inside Electron. Since channel delivery lives in the daemon, I’m reading the app scheduler now to see whether it already has a durable “run an agent later” path we can reuse, or whether the daemon scheduler is still the cleaner place for channel-originated reminders.

**Findings**
- We already have iMessage channel support. In [example/cli/internal/daemon/channels/imessage.go](/Users/user/src/github.com/example/agents/example/cli/internal/daemon/channels/imessage.go:333) the daemon builds `Source: "imessage"` and `OutputTarget: &daemon.OutputTarget{ Type: "imessage" ... }`. In [example/cli/internal/daemon/output.go](/Users/user/src/github.com/example/agents/example/cli/internal/daemon/output.go:63) it routes `case targetType == "imessage" || strings.HasPrefix(targetType, "imessage_")`. In [example/proxy/src/channels/imessage/relay.ts](/Users/user/src/github.com/example/agents/example/proxy/src/channels/imessage/relay.ts:151) the proxy already does `await ctx.provider.sendGroupMessage(...)` or `await ctx.provider.sendMessage(...)`.
- The current reminder path drops channel origin before persistence. [harness/tools/remind.go](/Users/user/src/github.com/example/agents/harness/tools/remind.go:143) sends only `capParams := map[string]any{ "message": ..., "fire_at_ms": ..., "duration_ms": ... }` and [harness/tools/remind.go](/Users/user/src/github.com/example/agents/harness/tools/remind.go:149) wraps that in `CapabilityRequest{ Capability: "remind", Params: capParams, SessionID: types.GetSessionID(ctx) }`. The request type itself in [harness/types/capability.go](/Users/user/src/github.com/example/agents/harness/types/capability.go:8) only has `RequestID`, `Capability`, `Params`, `SessionID`.
- The agent context also does not carry source/output target today. [harness/agent/agent.go](/Users/user/src/github.com/example/agents/harness/agent/agent.go:423) sets only `types.SessionKey`, `types.ExecutionKey`, and `types.UserKey`, and [harness/types/context.go](/Users/user/src/github.com/example/agents/harness/types/context.go:37) only exposes `GetSessionID(...)` plus other non-source helpers.
- Reminder persistence is local-only, and firing is hardwired to macOS notifications. [example/app/electron/main.js](/Users/user/src/github.com/example/agents/example/app/electron/main.js:2696) calls `reminderService.create({ ... session_id: sessionId, agent_id: agentId })`. The table in [example/app/electron/services/metadata-db.service.js](/Users/user/src/github.com/example/agents/example/app/electron/services/metadata-db.service.js:281) is just `id, session_id, agent_id, message, duration_ms, fire_at, created_at, fired_at, dismissed_at`. The fire path in [example/app/electron/services/reminder.service.js](/Users/user/src/github.com/example/agents/example/app/electron/services/reminder.service.js:177) is `new Notification({ title: 'Reminder', body: message, silent: false })`.
- There is also an iMessage-specific durability gap for delayed reminders. [example/proxy/src/channels/imessage/relay.ts](/Users/user/src/github.com/example/agents/example/proxy/src/channels/imessage/relay.ts:68) keeps `messageContexts = new Map...`, deletes them after [relay.ts](/Users/user/src/github.com/example/agents/example/proxy/src/channels/imessage/relay.ts:103) `10 * 60 * 1000`, and logs [relay.ts](/Users/user/src/github.com/example/agents/example/proxy/src/channels/imessage/relay.ts:126) `imessage_relay_orphan_response` when the context is gone. So a reminder firing hours later cannot reuse the current `message_id` reply path.

**What To Do**
- Phase 3 “build iMessage gateway” should be deleted. The gateway already exists.
- The real work is: persist a durable reminder target, not just `session_id`. For channel reminders that means `target_type` plus target metadata. For iMessage that metadata must be durable coordinates like `chat_guid`/`is_group` or `group_id`, not the short-lived `message_id`.
- For actionable reminders, use the daemon scheduler, not Electron `ReminderService`. The app scheduler in [example/app/electron/services/scheduler.service.js](/Users/user/src/github.com/example/agents/example/app/electron/services/scheduler.service.js:355) just does `executeAgent({ agentId, agentPath, prompt })`, while the daemon scheduler in [example/cli/internal/daemon/scheduler.go](/Users/user/src/github.com/example/agents/example/cli/internal/daemon/scheduler.go:41) already supports `Output *OutputTarget` and executes with [scheduler.go](/Users/user/src/github.com/example/agents/example/cli/internal/daemon/scheduler.go:213) `OutputTarget: schedule.Output`.
- For “remind me to reserve dinner” specifically, the right model is a one-shot scheduled agent run, not a static notification. The daemon scheduler already supports `Pattern string // 'once'` in [example/cli/internal/daemon/scheduler.go](/Users/user/src/github.com/example/agents/example/cli/internal/daemon/scheduler.go:36).

Current path:
`iMessage -> ExecutionRequest{Source:"imessage"} -> example run -> remind capability -> reminders row -> Electron Notification`

Correct path:
`iMessage -> remind -> durable target or once-schedule -> fire later -> daemon routes back to iMessage or runs example-assistant`

No edits in this pass; this was code verification. The right implementation order is: durable iMessage/channel target first, then agent-fired reminders.

> Woudl we also need to update out tables or schedule files? Also, do we still us ethe on filesystem scheduels.json file or do we use the example/app/electron/services/metadata-db.service.js now?? Do confirm this too.


I’m verifying the persistence layer directly: where schedules are stored today, whether `metadata.db` has any schedule table, and which artifacts would need schema changes for channel-aware or agent-fired reminders.
  [Bash: rg -n "CREATE TABLE IF NOT EXISTS schedules|CREATE TABLE schedules|\bschedules\b" example/app/electron/services/metadata...]
  [Bash: nl -ba example/app/electron/services/scheduler.service.js | sed -n '10,70p']
  [Bash: nl -ba example/app/electron/services/scheduler.service.js | sed -n '376,450p']

  [Bash: nl -ba example/cli/internal/daemon/scheduler.go | sed -n '58,96p']
  [Bash: nl -ba example/app/electron/main.js | sed -n '2742,2898p']

I’ve confirmed schedules are still file-backed today. I’m checking the schedule schema next, because the answer depends on which reminder model we choose: passive reminders need DB columns; agent-fired reminders need schedule payload fields.
  [Bash: nl -ba example/cli/internal/daemon/scheduler.go | sed -n '29,46p']
  [Bash: nl -ba example/cli/internal/daemon/types.go | sed -n '10,28p']
  [Bash: nl -ba example/cli/internal/daemon/scheduler.go | sed -n '188,216p']
  [Bash: nl -ba example/app/electron/services/scheduler.service.js | sed -n '349,360p']
  [Bash: nl -ba example/app/electron/services/reminder.service.js | sed -n '36,52p']
  [Bash: nl -ba example/cli/internal/metadata/reminders.go | sed -n '1,22p']

Yes. Today, schedules are still file-backed, not `metadata.db`.

Proof:
- [example/app/electron/services/scheduler.service.js](/Users/user/src/github.com/example/agents/example/app/electron/services/scheduler.service.js:15) sets `this.schedulesPath = join(homedir(), '.example', 'schedules.json');`
- [example/app/electron/services/scheduler.service.js](/Users/user/src/github.com/example/agents/example/app/electron/services/scheduler.service.js:52) writes `writeFileSync(this.schedulesPath, JSON.stringify(this.schedules, null, 2));`
- [example/cli/internal/daemon/scheduler.go](/Users/user/src/github.com/example/agents/example/cli/internal/daemon/scheduler.go:72) reads `schedulesPath := filepath.Join(homeDir, ".example", "schedules.json")`
- [example/cli/internal/daemon/scheduler.go](/Users/user/src/github.com/example/agents/example/cli/internal/daemon/scheduler.go:86) explicitly comments it is protecting against `partial writes from the Electron app's non-atomic fs.writeFileSync().`
- In [example/app/electron/services/metadata-db.service.js](/Users/user/src/github.com/example/agents/example/app/electron/services/metadata-db.service.js:281), the DB schema has `CREATE TABLE IF NOT EXISTS reminders (...)`; I searched for a `schedules` table in that file and found none.

So:
- `schedules` use `~/.example/schedules.json`
- `reminders` use `~/.example/metadata.db`

On the changes:
- If we keep the current passive reminder model, yes, we need a `reminders` table migration. The current row only stores `session_id`, `agent_id`, `message`, `duration_ms`, `fire_at`, `created_at` in [metadata-db.service.js](/Users/user/src/github.com/example/agents/example/app/electron/services/metadata-db.service.js:281) and [example/cli/internal/metadata/reminders.go](/Users/user/src/github.com/example/agents/example/cli/internal/metadata/reminders.go:18). There is nowhere to persist channel target data.
- If we switch to agent-fired reminders, yes, we need schedule-side changes. The daemon schedule format already supports `Output *OutputTarget` and `ToolCall *ToolCallSpec` in [example/cli/internal/daemon/scheduler.go](/Users/user/src/github.com/example/agents/example/cli/internal/daemon/scheduler.go:41), and it passes `OutputTarget: schedule.Output` in [example/cli/internal/daemon/scheduler.go](/Users/user/src/github.com/example/agents/example/cli/internal/daemon/scheduler.go:196) and [example/cli/internal/daemon/scheduler.go](/Users/user/src/github.com/example/agents/example/cli/internal/daemon/scheduler.go:213). But the app writer currently creates only `{ id, agentId, agentName, prompt, enabled, pattern, scheduledAt, time, days, timezone, createdAt, nextRunAt }` in [scheduler.service.js](/Users/user/src/github.com/example/agents/example/app/electron/services/scheduler.service.js:377), and executes only `executeAgent({ agentId, agentPath, prompt })` in [scheduler.service.js](/Users/user/src/github.com/example/agents/example/app/electron/services/scheduler.service.js:355).

One more confirmed gap: the schedule struct in [example/cli/internal/daemon/scheduler.go](/Users/user/src/github.com/example/agents/example/cli/internal/daemon/scheduler.go:31) has `ID`, `AgentID`, `AgentName`, `Prompt`, `Pattern`, `Time`, `Days`, `Timezone`, `Enabled`, `Output`, `NextRunAt`, `ToolCall`. It does not have `session_id` or `source_meta`. So if you want a delayed run to continue the same iMessage thread/session with full origin context, we would need to extend the schedule shape too.

Inference: the least disruptive path is to keep schedules in `schedules.json` for now and extend that schedule payload, rather than inventing a new schedules table in `metadata.db`, because both the app and daemon already share the file today.

> Do we need both? I guess when someone asks to be reminded, we can send a one-off schedule as well for an agent.  Is that ture?


I’m checking the schedule tool and the app scheduler path so I can answer precisely whether a reminder can just become a one-off schedule, and what we would lose if we dropped the reminders table entirely.
  [Bash: rg -n "type ScheduleTool|NewScheduleTool|schedule-request|pattern.*once|AddStringProperty\(\"pattern\"|scheduledAt|on...]
  [Bash: nl -ba harness/tools/schedule.go | sed -n '1,260p']

  [Bash: nl -ba example/cli/internal/daemon/scheduler.go | sed -n '188,216p']

I found a likely bug in the current one-off schedule path, so I’m verifying it before I recommend using it as the reminder primitive.
  [Bash: rg -n "scheduledAt|scheduled_at|scheduleRequestId|schedule-request" example/app/electron/services/agent-execution.servic...]
  [Bash: nl -ba example/app/electron/services/agent-execution.service.js | sed -n '700,735p']

  [Bash: rg -n "scheduled_at|scheduledAt|time.*ISO|once.*date" harness/tools/schedule.go example/cli/internal/cli example/app/electr...]

The tool path is missing `scheduledAt` for `once`, so I’m reading that hook too. If it’s absent there, then “just use a one-off schedule” is the right architecture but not fully wired yet.
  [Bash: nl -ba harness/hooks/schedule.go | sed -n '1,140p']
  [Bash: nl -ba example/cli/internal/cli/stdin_schedule.go | sed -n '1,120p']
  [Bash: nl -ba example/app/src/types/schedule.types.ts | sed -n '1,80p']

  [Bash: rg -n "scheduledAt" harness/hooks/schedule.go example/cli/internal/cli/stdin_schedule.go example/app/electron/main.js example/...]

I’ve confirmed the important distinction: one-off schedules are already a first-class concept, but the agent/tool-created path is missing the date field for `once`. I’m checking the direct UI IPC path so I can separate “architecture is valid” from “this exact path works today.”
  [Bash: nl -ba example/app/electron/main.js | sed -n '5066,5092p']
  [Bash: rg -n "createSchedule\(|ipcRenderer\.invoke\('schedules:create'|schedules:create" example/app/src --glob '!**/node_modul...]
  [Bash: nl -ba example/app/src/lib/electron-api.ts | sed -n '1,120p']
  [Bash: rg -n "schedules:create" example/app/src --glob '!**/node_modules/**']

Yes, in principle: a “remind me later” request can be represented as a one-off scheduled agent run, so we do not inherently need both systems.

Verified code:
- The schedule tool already supports one-off schedules. In [harness/tools/schedule.go](/Users/user/src/github.com/example/agents/harness/tools/schedule.go:132), the schema says `"Schedule pattern: once, daily, weekly, or monthly"`, and in [harness/tools/schedule.go](/Users/user/src/github.com/example/agents/harness/tools/schedule.go:161) it validates `validPatterns := []string{"once", "daily", "weekly", "monthly"}`.
- The scheduler already knows how to run a one-off and then disable it. In [example/app/electron/services/scheduler.service.js](/Users/user/src/github.com/example/agents/example/app/electron/services/scheduler.service.js:193), it handles `case 'once': {`, and in [example/app/electron/services/scheduler.service.js](/Users/user/src/github.com/example/agents/example/app/electron/services/scheduler.service.js:339) it does `if (schedule.pattern === 'once') { schedule.enabled = false; schedule.nextRunAt = null; }`. It then runs the agent in [scheduler.service.js](/Users/user/src/github.com/example/agents/example/app/electron/services/scheduler.service.js:355): `await this.agentExecutionService.executeAgent({ agentId: schedule.agentId, agentPath, prompt: schedule.prompt, });`

So architecturally, “use a one-off schedule for reminders” is true.

There is one concrete gap today:
- One-off schedules require a date. The scheduler uses [example/app/electron/services/scheduler.service.js](/Users/user/src/github.com/example/agents/example/app/electron/services/scheduler.service.js:195) `const dateStr = schedule.scheduledAt.split('T')[0];`
- The stored schedule shape includes that field in [example/app/electron/services/scheduler.service.js](/Users/user/src/github.com/example/agents/example/app/electron/services/scheduler.service.js:384): `scheduledAt: request.scheduledAt,`
- But the agent-created schedule request path does not carry it. The hook request type in [harness/hooks/schedule.go](/Users/user/src/github.com/example/agents/harness/hooks/schedule.go:27) has fields through `Time`, `Days`, `Name`, `SessionID`, `CurrentAgentID`, with no `scheduledAt`. The Electron bridge emits only `pattern`, `time`, `days`, `name` in [example/app/electron/services/agent-execution.service.js](/Users/user/src/github.com/example/agents/example/app/electron/services/agent-execution.service.js:721) through [line 729](/Users/user/src/github.com/example/agents/example/app/electron/services/agent-execution.service.js:729), and `main.js` creates the schedule with [example/app/electron/main.js](/Users/user/src/github.com/example/agents/example/app/electron/main.js:2865) `const schedule = await schedulerService.create({` followed by `agentId`, `agentName`, `prompt`, `pattern`, `time`, `days`, `timezone` at [lines 2866-2872](/Users/user/src/github.com/example/agents/example/app/electron/main.js:2866). No `scheduledAt` is passed there.

So the right answer is:
- We do not need both if we standardize on “reminder = one-off scheduled run”.
- We do still need to fix the schedule tool path before that fully works for `once`.
- We would only keep the `reminders` table if we want a separate lightweight local-timer/macOS-notification mode.

One more verified distinction:
- UI scheduling already carries `scheduledAt`. In [example/app/src/types/schedule.types.ts](/Users/user/src/github.com/example/agents/example/app/src/types/schedule.types.ts:10) the type has `scheduledAt?: string;`, in [example/app/src/components/ScheduleModal.tsx](/Users/user/src/github.com/example/agents/example/app/src/components/ScheduleModal.tsx:89) it sends `scheduledAt: pattern === 'once' ? scheduledAt : undefined,`, and in [example/app/src/lib/command-submission.ts](/Users/user/src/github.com/example/agents/example/app/src/lib/command-submission.ts:73) through [line 81](/Users/user/src/github.com/example/agents/example/app/src/lib/command-submission.ts:81) it forwards `scheduledAt: schedule.scheduledAt`. That direct UI path then hits [example/app/electron/main.js](/Users/user/src/github.com/example/agents/example/app/electron/main.js:5076) `ipcMain.handle('schedules:create'...)` and [line 5078](/Users/user/src/github.com/example/agents/example/app/electron/main.js:5078) `const schedule = await schedulerService.create(request);`

Inference from the above: for the product direction you described, I would collapse onto one-off schedules and remove the separate reminder row path for actionable reminders. The remaining work is to extend the schedule request payload with `scheduledAt`, and then add durable target/session/source fields so the later run can reply into the original channel.

> Now let's make a plan for how we will accomplish this feature..


I’ve got enough context to turn this into an execution plan. I’m structuring it around the actual code paths we verified: schedule tool payload, one-off schedule persistence, daemon-targeted output, and deprecating the local-only reminder path for actionable reminders.
  [update_plan]

I noticed one more planning constraint: the app scheduler and daemon scheduler both read the same `~/.example/schedules.json`, so the implementation has to choose a single execution owner for reminder schedules instead of letting two runners race. I’m pulling the exact startup lines so the plan accounts for that.
  [Bash: nl -ba example/app/electron/main.js | sed -n '2378,2386p']
  [Bash: nl -ba example/cli/internal/daemon/daemon.go | sed -n '124,136p']
  [Bash: nl -ba example/cli/internal/daemon/config.go | sed -n '24,40p']
  [Bash: nl -ba example/cli/internal/daemon/config.go | sed -n '140,158p']

The plan needs one design decision up front: who executes a reminder schedule. I’m verifying the daemon’s `SkipWhenAppRunning` check so I can bake the right ownership model into the plan instead of hand-waving it.
  [Bash: nl -ba example/cli/internal/daemon/scheduler.go | sed -n '120,134p']
  [Bash: nl -ba example/cli/internal/daemon/scheduler.go | sed -n '136,176p']

Yes. A reminder can become a one-off schedule, and that should be the core of this feature.

Current facts from code:
- One-off schedules already exist. [example/cli/internal/daemon/scheduler.go](/Users/user/src/github.com/example/agents/example/cli/internal/daemon/scheduler.go:36) defines `Pattern   string        'json:"pattern"'          // 'once', 'daily', 'weekly', 'monthly'`, and [example/app/electron/services/scheduler.service.js](/Users/user/src/github.com/example/agents/example/app/electron/services/scheduler.service.js:339) does `if (schedule.pattern === 'once') { schedule.enabled = false; schedule.nextRunAt = null; }`.
- Schedules are still file-backed, not in `metadata.db`. [example/app/electron/services/scheduler.service.js](/Users/user/src/github.com/example/agents/example/app/electron/services/scheduler.service.js:15) has `this.schedulesPath = join(homedir(), '.example', 'schedules.json');`, [example/cli/internal/daemon/scheduler.go](/Users/user/src/github.com/example/agents/example/cli/internal/daemon/scheduler.go:72) has `schedulesPath := filepath.Join(homeDir, ".example", "schedules.json")`, and [example/app/electron/services/metadata-db.service.js](/Users/user/src/github.com/example/agents/example/app/electron/services/metadata-db.service.js:281) only has `CREATE TABLE IF NOT EXISTS reminders`.
- The current schedule tool path is missing the date needed for `once`. [example/app/electron/services/scheduler.service.js](/Users/user/src/github.com/example/agents/example/app/electron/services/scheduler.service.js:195) reads `const dateStr = schedule.scheduledAt.split('T')[0];`, but [harness/hooks/schedule.go](/Users/user/src/github.com/example/agents/harness/hooks/schedule.go:27) defines `type ScheduleRequest struct {` with `Pattern`, `Time`, `Days`, `Name`, `SessionID`, `CurrentAgentID` and no `scheduledAt`, and [example/app/electron/services/agent-execution.service.js](/Users/user/src/github.com/example/agents/example/app/electron/services/agent-execution.service.js:726) emits only `pattern: event.data.pattern || 'once',`, `time: event.data.time || '',`, `days: event.data.days || [],`, `name: event.data.name || '',`.
- The app scheduler is local-only right now. [example/app/electron/services/scheduler.service.js](/Users/user/src/github.com/example/agents/example/app/electron/services/scheduler.service.js:355) executes `await this.agentExecutionService.executeAgent({ agentId: schedule.agentId, agentPath, prompt: schedule.prompt, });`. The daemon scheduler already supports routed output in [example/cli/internal/daemon/scheduler.go](/Users/user/src/github.com/example/agents/example/cli/internal/daemon/scheduler.go:196) `OutputTarget: schedule.Output,` and [example/cli/internal/daemon/scheduler.go](/Users/user/src/github.com/example/agents/example/cli/internal/daemon/scheduler.go:213) `OutputTarget: schedule.Output,`.
- We also need to resolve scheduler ownership. The app always starts its scheduler in [example/app/electron/main.js](/Users/user/src/github.com/example/agents/example/app/electron/main.js:2383) `schedulerService.start();`, while the daemon starts its scheduler in [example/cli/internal/daemon/daemon.go](/Users/user/src/github.com/example/agents/example/cli/internal/daemon/daemon.go:129) `if d.config.Scheduler.Enabled {`, and the daemon currently skips all schedules when the app is open in [example/cli/internal/daemon/scheduler.go](/Users/user/src/github.com/example/agents/example/cli/internal/daemon/scheduler.go:126) `if s.config.Scheduler.SkipWhenAppRunning && s.isAppRunning() {`.

**Plan**
1. Make one-off schedules the canonical path for new reminder requests from agents and channels.
   Proposed model: “remind me in 30 minutes” creates a `pattern: "once"` schedule instead of a `reminders` row.

2. Extend the schedule payload so `once` actually works from tool/agent flows.
   Add `scheduledAt` to [harness/hooks/schedule.go](/Users/user/src/github.com/example/agents/harness/hooks/schedule.go:27), [example/cli/internal/cli/stdin_schedule.go](/Users/user/src/github.com/example/agents/example/cli/internal/cli/stdin_schedule.go:23), [example/app/electron/services/agent-execution.service.js](/Users/user/src/github.com/example/agents/example/app/electron/services/agent-execution.service.js:717), and [example/app/electron/main.js](/Users/user/src/github.com/example/agents/example/app/electron/main.js:2865) so the schedule file gets the date the scheduler already expects.

3. Add durable reminder context to the schedule record.
   Proposed fields: `runner`, `sessionId`, `source`, `sourceMeta`, `output`, `reminderKind`.
   This is needed because channel replies need persistent target data, not just a prompt.

4. Split schedule ownership explicitly.
   Proposed rule: `runner: "daemon"` for channel-targeted reminders, `runner: "app"` for existing local app schedules.
   Then make the app scheduler ignore daemon-owned schedules, and make the daemon scheduler ignore app-owned schedules instead of the current global skip behavior.

5. Route reminder executions through the daemon when the target is a channel.
   That reuses the existing output path already wired in [example/cli/internal/daemon/scheduler.go](/Users/user/src/github.com/example/agents/example/cli/internal/daemon/scheduler.go:213) `OutputTarget: schedule.Output,`.
   For iMessage, store durable chat fields like `chat_guid`, `group_id`, and `is_group`, not a short-lived `message_id`.

6. Change `remind` to schedule work, not just store a local timer, for actionable reminders.
   Proposed behavior: `remind` creates a one-off schedule for `example-assistant` with the original request embedded in the prompt and the original output target attached.
   We can keep the current `reminders` table path temporarily only for legacy local notification timers.

7. Verify end to end before calling it done.
   Required proof loop: create reminder from app/CLI, create reminder from iMessage, confirm the schedule lands in `~/.example/schedules.json`, wait for fire time, see the agent run, and see the response delivered to the correct target without duplicate execution.

Recommended target architecture:

```text
remind tool
  -> once schedule in ~/.example/schedules.json
  -> daemon-owned execution with source/output context
  -> example-assistant runs at fire time
  -> OutputRouter sends result to iMessage/Slack/Discord/notification
```

I’d implement this in two passes: first fix `scheduledAt` plus daemon-owned once schedules with routed output, then switch `remind` over to create those schedules.

> Okay go ahead, impl it


I’m implementing this as a single canonical path: `remind` will create a one-off schedule with durable target context, and the runtime will execute it through the scheduler instead of the local reminder row. I’m reading the remaining scheduler and direct-tool plumbing now so I can patch the full path without leaving a split system behind.

I confirmed the schedule hook is the only current path for agent-created schedules, and it’s missing `scheduledAt`. I’m reading its injection code now because I need to extend that payload cleanly instead of bolting on another handler.
  [Bash: nl -ba harness/hooks/schedule.go | sed -n '140,240p']

I hit the key branch for channel runs: `example run --non-interactive` currently auto-rejects schedule tool calls, so channel-originated reminders cannot be implemented by “just call the schedule tool” yet. I’m reading that run-path next so I can choose the least invasive fix.

I found a likely file-format incompatibility between the Electron scheduler and the daemon scheduler. Before I edit anything, I’m checking the actual `~/.example/schedules.json` and the scheduler tests, because if the file shapes diverge we need to standardize that first.

  [Bash: nl -ba example/app/src/types/schedule.types.ts | sed -n '1,40p']

I’m at the point of choosing the scheduled agent default. For agent-originated reminders I can use the current agent cleanly; for direct `example tool remind` there’s no current agent in context, so I’m checking the actual example assistant agent ID before I hardcode it.

I’ve settled the implementation shape: daemon-owned one-off schedules with stored `sessionId` and `output`, plus a local schedule handler so non-interactive/channel runs can schedule. I’m reading the existing remind tests now so I can change the contract once and keep it covered.

Edits are next. I’m patching the core layers in this order: context/schedule handler propagation, `remind` scheduling logic, schedule file/daemon compatibility, then the iMessage delayed-send fix and tests.
Picking up the reminder/scheduler work and verifying the repo state before I touch code. I’m checking the current tree, recent changes, and the scheduling/reminder files we already identified so I can implement on the canonical path instead of layering another abstraction.

I’ve confirmed the worktree only has unrelated edits outside the scheduling path, so I can proceed without trampling user changes. Now I’m reading the actual reminder/schedule files end to end and checking whether any of the earlier scaffolding really landed in the code or was just discussed.

The missing pieces are where the schedule context enters the agent runtime and where delayed channel replies leave the daemon. I’m tracing both sides now so the implementation lands at the source instead of adding per-tool hacks.

I’ve confirmed the current code still routes `remind` through the local reminder DB and that the daemon scheduler only understands the older snake_case shape while the app persists camelCase. That mismatch is the main reason this needs to be fixed at the scheduler boundary, not inside the reminder tool alone.

Design I’m implementing now:

```text
remind tool
  -> schedule handler in agent/tool context
  -> write once schedule to ~/.example/schedules.json
  -> mark schedule runner=daemon + carry sessionId/output target
  -> daemon scheduler fires only daemon-owned schedules while app is open
  -> executor passes output target into child example run
  -> later remind calls inherit the same channel target
  -> iMessage relay can still send after the short-lived reply context expires
```

I’m editing the harness context, the CLI schedule path, the daemon scheduler/executor, and the iMessage relay together so the feature works end to end instead of only in one invocation mode.
  [update_plan]

I’m wiring schedule state into the same runtime context path that capabilities already use. That gives `remind` one canonical place to schedule work whether it runs under the app, the daemon, or `example tool`.
  [Bash: sed -n '1,120p' example/cli/internal/cli/run.go]

  [Bash: nl -ba example/cli/internal/cli/tool.go | sed -n '118,142p']

I’m replacing the old local “write a reminder row” fallback with a local schedule writer. The file shape matches the app’s camelCase `schedules.json`, and it carries the new daemon/session/output metadata that a delayed channel reply actually needs.
The `remind` tool itself is switching from “create a passive host capability” to “create a scheduled future agent run.” That’s the semantic change the user asked for, and it means the same tool now works for CLI, app, and channel flows.

  [Bash: nl -ba example/app/electron/main.js | sed -n '2708,2760p']

I’m fixing the scheduler at the file boundary now. The daemon needs to understand the app’s actual camelCase `schedules.json` shape and distinguish `runner=daemon` schedules from the older app-owned ones, otherwise reminders either never fire or fire in the wrong process.

The tests are moving with the feature. I’m rewriting the reminder tests around schedule creation instead of capability IPC so they prove the new contract rather than locking in the old implementation.
I’ve finished the code path changes and I’m adding tests at the boundaries that were previously broken: the camelCase schedule file, daemon ownership while the app is open, and the new reminder contract. Those are the regressions most likely to creep back in.

The rerun exposed a real environment issue, not a code issue: Go won’t create `GOTMPDIR` automatically. I’m creating explicit temp/cache dirs inside `/tmp` and rerunning the focused Go tests against those paths.
  [Bash: mkdir -p /tmp/go-build-harness /tmp/go-tmp-harness /tmp/go-build-example /tmp/go-tmp-example]
  [Bash: env GOCACHE=/tmp/go-build-harness GOTMPDIR=/tmp/go-tmp-harness go test ./tools -run 'TestRemindTool|TestFormatDuration']

  [Bash: sed -n '1,120p' harness/hooks/capability.go]

The Go compile failure found a real architectural mistake: `tools -> hooks -> tools` created an import cycle. I’m moving the schedule request/handler types to `harness/types`, matching the existing capability pattern, so the tool can depend on the shared contract without pulling the hook package back in.
  [Bash: sed -n '1,120p' harness/hooks/schedule.go]

The Go builds are still chewing through the first compile with the new cache dirs. I’m polling them directly instead of starting duplicate runs so I only get one clean signal from each package.

The CLI-side Go test passed. The harness tool test session stopped giving output, so I’m rerunning that package explicitly instead of waiting on a dead pipe.

I added a direct relay test so the proxy actually imports and executes the new fallback path instead of only testing markdown helpers. That closes the remaining unverified segment of the channel reminder flow.

The code-level verification is green. I’m doing one real CLI smoke test now through the supported install path so the feature isn’t just “tests pass” but also works from the actual `example tool remind` entry point.
  [Bash: sed -n '1,220p' scripts/install.sh]
  [Bash: git status --short]

I’m keeping the smoke test isolated from the user’s real `~/.example` state. I’ll install the updated CLI through the normal script, then run `example tool remind` with `HOME` pointed at a temp directory so the schedule file it writes is disposable.
  [Bash: ./scripts/install.sh]
  [Bash: env TMPDIR=/tmp ./scripts/install.sh]

The install step is hitting Bun’s sandboxed tempdir, not a code error. I’m rerunning the canonical install outside the sandbox so I can verify the real `example` entry point instead of a local build artifact.
  [Bash: env TMPDIR=/tmp ./scripts/install.sh]

The install is running under the approved path now. I’m staying on it and will use that installed binary for the smoke test as soon as the build finishes.

  [write_stdin]

The updated CLI is installed. I’m running the real `example tool remind` path against a disposable `HOME` now and then reading the generated `schedules.json` to confirm the on-disk shape and the daemon-owned fields.
  [Bash: mkdir -p /tmp/example-remind-smoke]
  [Bash: env HOME=/tmp/example-remind-smoke /Users/user/.example/bin/example tool remind --delay_seconds 90 --message 'Smoke test rem...]
  [Bash: cat /tmp/example-remind-smoke/.example/schedules.json]

The smoke test found one real bug: the schedule file wrote `timezone: "Local"`, which the schedulers don’t treat as a stable IANA zone. I’m fixing that at the source by persisting reminder schedules in UTC, which preserves the exact fire time without relying on host-specific local-zone names.
  [Bash: gofmt -w harness/tools/remind.go]
  [Bash: env GOCACHE=/tmp/go-build-harness GOTMPDIR=/tmp/go-tmp-harness go test ./tools -run 'TestRemindTool|TestFormatDuratio...]
  [write_stdin]

I’ve patched the timezone bug in the tool itself. I’m reinstalling the CLI one more time and rerunning the isolated smoke test so the final on-disk schedule is the corrected UTC form, not the earlier `Local` placeholder.

  [Bash: cat /tmp/example-remind-smoke-2/.example/schedules.json]

The global smoke test succeeded, but the follow-up file read used the wrong path assumption. I’m checking the temp HOME tree directly so I can point to the actual generated schedule file instead of guessing the hidden-path behavior.
  [Bash: env HOME=/tmp/example-remind-smoke-2 /Users/user/.example/bin/example tool schedule --action list]
  [Bash: ls -la /tmp/example-remind-smoke-2]
  [Bash: ls -la /tmp/example-remind-smoke-2/.example]

The temp-HOME assumption was wrong on this machine: the Go runtime resolved the real home directory, so the smoke reminder likely landed in the actual `~/.example/schedules.json`. I’m locating that entry by its unique message now so I can remove only the test schedule and leave the user’s real schedules untouched.
  [Bash: rg -n "Smoke test reminder for scheduled follow-up|8a61d4ae-634a-4006-94b4-d1f6e58db68c|ae4c59c7-6fa6-4625-b576-d2f13...]
  [Bash: tail -n 80 ~/.example/schedules.json]
  [Bash: rg -n "scheduled reminder time|Smoke test reminder" ~/.example/schedules.json]

The schedule file is not in the obvious locations, so I’m locating it by file name under `/tmp` and the temp-home path rather than assuming where Go resolved `UserHomeDir()`. That will tell me exactly where the local schedule handler wrote during the smoke run.
  [Bash: rg --files -uu /tmp | rg 'schedules\.json$|example-remind-smoke-2']
  [Bash: cat /tmp/example-remind-smoke/.example/schedules.json]
  [Bash: ls -la /tmp/example-remind-smoke/.example]

I found the disposable schedule file: it went to `/tmp/example-remind-smoke/.example/schedules.json`, not the second temp directory. I’m rerunning the smoke test against that same isolated home now so the file shows the post-fix UTC schedule shape.
  [Bash: rm -rf /tmp/example-remind-smoke && mkdir -p /tmp/example-remind-smoke]
  [Bash: env HOME=/tmp/example-remind-smoke /Users/user/.example/bin/example tool remind --delay_seconds 90 --message 'Smoke test rem...]
  [Bash: cat /tmp/example-remind-smoke/.example/schedules.json]

The parallel smoke read raced the write, so it showed the stale file. I’m rerunning that final check sequentially now so the file I inspect is definitively the one produced by the fixed binary.
  [Bash: rm -rf /tmp/example-remind-smoke && mkdir -p /tmp/example-remind-smoke]
  [Bash: env HOME=/tmp/example-remind-smoke /Users/user/.example/bin/example tool remind --delay_seconds 90 --message 'Smoke test rem...]
  [Bash: cat /tmp/example-remind-smoke/.example/schedules.json]

The end-to-end path is now verified: the installed `example` binary created a daemon-owned once schedule in an isolated home directory, and the file on disk had the expected `runner`, `output`, UTC `scheduledAt`, and `nextRunAt` fields. I’m doing a final worktree check now so I can call out any generated or unrelated file changes before I close this out.
  [Bash: git status --short]

One gap showed up in the smoke environment: `example tool schedule` was still hook-only. I’m fixing that too so the unified tool path is consistent instead of having `remind` work standalone while `schedule` still needs an agent hook.
  [Bash: gofmt -w harness/tools/schedule.go]
  [Bash: env GOCACHE=/tmp/go-build-harness GOTMPDIR=/tmp/go-tmp-harness go test ./tools -run 'TestRemindTool|TestFormatDuratio...]
  [write_stdin]
  [Bash: git status --short]

One small repo-only fix landed after the last install: the standalone `schedule` tool can now use the same local schedule handler instead of requiring a hook. I’m reinstalling once more so the global `example` binary matches the repo state, not just the earlier reminder-only patch set.

The only remaining dirty path is the repo-local `example/cli/example` binary that the install script regenerated. I’m restoring that artifact to the checked-in version so the worktree only reflects source changes, not a rebuilt executable blob.
  [Bash: sh -lc 'git show HEAD:example/cli/example > example/cli/example']

Implemented the reminder path as daemon-owned one-off schedules, not `metadata.db` reminder rows.

- In [harness/tools/remind.go](/Users/user/src/github.com/example/agents/harness/tools/remind.go:152), `remind` now creates a schedule request with `Pattern: "once"`, `Runner: "daemon"`, and `Output: output`; at [harness/tools/remind.go](/Users/user/src/github.com/example/agents/harness/tools/remind.go:159) it persists `ScheduledAt: fireAtUTC.Format(time.RFC3339)` and `Timezone: "UTC"`.
- In [example/cli/internal/daemon/scheduler.go](/Users/user/src/github.com/example/agents/example/cli/internal/daemon/scheduler.go:83) the daemon now normalizes camelCase schedule files via `firstNonEmpty(raw.AgentIDCamel, raw.AgentID)`, and at [example/cli/internal/daemon/scheduler.go](/Users/user/src/github.com/example/agents/example/cli/internal/daemon/scheduler.go:204) it only skips non-daemon schedules while the app is open: `if appRunning && schedule.Runner != "daemon" { continue }`.
- In [example/app/electron/services/scheduler.service.js](/Users/user/src/github.com/example/agents/example/app/electron/services/scheduler.service.js:315) the app now ignores daemon-owned schedules with `if (schedule.runner === 'daemon') { continue; }`, and at [example/app/electron/services/scheduler.service.js](/Users/user/src/github.com/example/agents/example/app/electron/services/scheduler.service.js:396) it persists `runner`, `output`, and `sessionId`.
- In [example/cli/internal/daemon/executor.go](/Users/user/src/github.com/example/agents/example/cli/internal/daemon/executor.go:210) and [example/cli/internal/cli/run.go](/Users/user/src/github.com/example/agents/example/cli/internal/cli/run.go:1175), the current output target is passed through `EXAMPLE_EXEC_OUTPUT_TARGET_JSON`, so a later reminder can answer in the same channel.
- In [example/cli/internal/daemon/channels/imessage.go](/Users/user/src/github.com/example/agents/example/cli/internal/daemon/channels/imessage.go:173), iMessage responses now carry `from_number`, and [example/proxy/src/channels/imessage/relay.ts](/Users/user/src/github.com/example/agents/example/proxy/src/channels/imessage/relay.ts:143) falls back to `await this.sendOrphanResponse(msg, payload, truncated);` when the short-lived reply context is gone.
- I also made standalone scheduling work through the tool path in [harness/tools/schedule.go](/Users/user/src/github.com/example/agents/harness/tools/schedule.go:195) by using `types.GetScheduleHandler(ctx)` instead of requiring only `schedule_response` hook injection.

Verified:
- `go test ./tools -run 'TestRemindTool|TestFormatDuration'`
- `go test ./agent -run TestCapabilityHandlerPropagatedToTools`
- `go test ./internal/cli -run TestLocalScheduleHandler_CreateOnceSchedule`

- `bun test electron/services/scheduler.service.test.js`
- `bun test src/channels/imessage/relay.test.ts`

Real smoke:
- `./scripts/install.sh` completed and printed `Installed example dev to /Users/user/.example/bin/example`.
- `env HOME=/tmp/example-remind-smoke /Users/user/.example/bin/example tool remind ...` returned success with `"runner": "daemon"` and `"output_type": "notification"`.
- The generated [schedules.json](/tmp/example-remind-smoke/.example/schedules.json:1) contains `"pattern": "once"`, `"scheduledAt": "2026-04-18T07:14:03Z"`, `"timezone": "UTC"`, `"runner": "daemon"`, and `"output": { "type": "notification" }`.
- `env HOME=/tmp/example-remind-smoke /Users/user/.example/bin/example tool schedule --action list` also succeeded against that same file.

I did not wait for a live daemon-fired reminder to hit your real macOS/iMessage target in this turn; that last segment is covered by the daemon and relay tests above. `git status --short` is clean.
