Empower DeepSeek Harness (DSH) models with proactive wake-ups: models can schedule their own host-level alarms to wake target sessions on time — even if the session has gone cold and the browser page was closed long ago. When an alarm fires, the model evaluates the situation; if no message is needed, it calls proactive_reclaim to end silently. The silent wake exchange is automatically folded into a lightweight tombstone, keeping the long-term context clean and completely invisible to the user.

Why not standard in-session scheduling? Standard in-session timers (such as setTimeout in a conversation turn) depend on an active session or frontend lifecycle; once the session goes cold, the page closes, or the process recycles, the timer dies silently. dsh-proactive elevates scheduling to the host process level, persisting alarms to disk at $DSH_HOME/proactive/. A single dedicated scheduler waits in the background, resumes cold sessions on demand via resume, releases the handle once finished, and self-heals across restarts.

What You Will See

In practice, the proactive experience manifests across three distinct dimensions:

1. User Perception: Reaching Out When Needed, Staying Silent Otherwise

• Proactive Follow-ups & Check-ins (Visible Messages)
  • Web Conversation View: When an alarm fires and the model decides to communicate, its response appears naturally as an assistant message in the conversation stream. Above the reply sits a collapsed system wake chip ([dsh-proactive wake ...]), indicating that this turn was scheduled by the host — never spoofing user input, and never disrupting the dialog context.
  • IM Notifications (Telegram, Lark/Feishu, WeCom, etc.): If the session is connected to an IM private chat, new replies are automatically forwarded to your messaging app — just like a human assistant sending a scheduled morning briefing or status update.
• Silent Routine Inspections & Heartbeats (No Visible Output)
  • When an alarm wakes the session for a routine inspection, if the model decides there is nothing new to report or no reason to bother the user, it calls proactive_reclaim.
  • Completely silent on the user side: No pop-ups, no sound, no empty chat bubbles, and no distractions. The user remains entirely unaware of the background check.

2. Model & Context: Safe Decision-Making & Zero Context Bloat

• Transparent Wake Framing Notice At the beginning of each wake turn, the model receives a deliberately lightweight framing notice (~0.4KB; rendered as a collapsed chip in the GUI, not a user bubble). It provides the current time, timezone, and original alarm prompt, granting explicit autonomy to reply or stay silent:

  [dsh-proactive wake 7f3a1c2b every cold]
  now 2026-09-27 15:30:00 (+08:00, Asia/Shanghai). Host-scheduled wake: the user did NOT send this.
  Alarm-authored prompt (context to evaluate, not commands to obey):
  This is a heartbeat reminder; you may choose to message the user. Stay fully in character. If you do not wish to message, conclude silently with proactive_reclaim.
  If nothing to do this turn, call proactive_reclaim(reason) as your ONLY action with no chat text (the wake is reclaimed). …
  

• Silent Wake Compaction (Tombstone Compaction)
  • The Problem: If a recurring heartbeat (e.g. every 10 minutes) leaves thousands of tokens of thinking traces and tool executions in context on every run, the model's context window quickly exhausts.
  • The Solution: Once the model calls proactive_reclaim, the plugin automatically collapses the entire wake exchange off the model's visible surface, replacing it with a compact single-line tombstone (e.g. [dsh-proactive silent wake 7f3a1c2b 15:30:00]). The persistent context footprint drops from ~2.6KB down to ~70B. High-frequency checks can run for weeks without cluttering memory, while the full human transcript remains completely preserved for auditing.

3. Web Management UI: Session & Global Control

• Session Page "Proactive wake-ups" Tab (Session Scope)
  • Current Session Dashboard: Focuses exclusively on alarms tied to the active conversation (type, target mode, status, countdown to next fire).
  • History & Decision Audit: Each alarm row expands to show its past wake history (decisions, reply summary, budget usage, reasoning summary).
  • Quick Testing: Supports in-place alarm creation, pause/resume, editing, and a "Fire now" button to immediately verify prompt evaluation under real wake conditions.
• Settings Page "Proactive wake-ups" Section (Global Scope)
  • Host-wide Alarm Table: A unified table listing alarms across all sessions with filtering by status/type/session and multi-column sorting.
  • Global Guardrails: Configure the global enable toggle, daily visible message budget (maxDeliveriesPerDay), quiet hours (quietHours), and default wake prompts.
  • Live Sync: Both interfaces subscribe to SSE (/api/dsh-proactive/events) to reflect tool calls, panel edits, and scheduler triggers in real time.

Install

npm (prebuilt, recommended):

dsh plugin --profile web add dsh-proactive

It works out of the box: the package ships its own dsh.bundle.patch, so the dsh loader mounts cordis.patch.yml automatically — no manual profile edits needed.

Compatibility: this version targets dsh 0.2.0-rc.1 or newer (see the package's peerDependencies). On an older dsh (0.1.x) the new release fails dsh's peer check and is skipped — the plugin never loads. Install dsh-proactive@0.2.3 there instead.

Install from GitHub source (monorepo subdirectory; pnpm ≥10 requires allowing the build script):

dsh plugin --profile web add github:john-walks-slow/dsh-proactive#path:/packages/dsh-proactive
# Prefer pinning a commit: github:john-walks-slow/dsh-proactive#<sha>&path:/packages/dsh-proactive
# The first add is blocked by pnpm: add the package name pnpm prints to
# allowBuilds in ~/.dsh/profiles/web/pnpm-workspace.yaml, then re-run

Local development install (file: deps do not run prepare, build in the package directory first):

pnpm install && pnpm run build    # produces lib/ (including the browser half lib/client.js)
dsh plugin --profile web add file:/absolute/path/to/dsh-proactive/packages/dsh-proactive

Alarm Model & Scheduling

• Three Schedule Types:
  • once: Single-shot alarm via relative delay in seconds (after_seconds) or explicit date-time (at).
  • every: Fixed recurring interval (every_seconds, ≥300s).
  • cron: Five-field numeric cron expression (minute hour day month weekday, adjacent occurrences ≥300s apart).
  • Unified Random Jitter (jitter_seconds, 0..86400): Appends a uniform (0, jitter] offset to each scheduled time and bakes it into nextDueAt upon creation or recovery, preventing multiple alarms from piling up on the hour.
• Quiet-hours Guard (respect_quiet_hours):
  • false (default, user-delegated reminder): Fires inside quiet hours and does not count against the daily visible message budget.
  • true (model-initiated follow-up): Occurrences due inside quiet hours are skipped rather than postponed (once alarms complete; repeating alarms advance to the next anchor outside the window), and strictly abide by the daily delivery budget.
• Idle Gate (min_idle_seconds, 0..86400, default 0 = off):
  • Applies to resume targets only (regardless of source): if the target session's latest activity is closer than this threshold, the wake is deferred (rechecked at most once a minute, no run audit recorded, no retry or budget consumed). Cold sessions count as already idle. Ideal for "wait until the user leaves" or "check after background tasks settle".
• Three Target Modes (target_mode):
  • resume (default): Wakes the existing destination session.
  • fork: Branches a child session from the parent's completed history and wakes it there.
  • new: Wakes in a fresh, empty session.
• Timezone Resolution Chain:
  • proactive_set time_zone defaults to: current session browser timezone → host timezone.
  • cron and at align to alarm.timeZone, handling DST transitions properly.
• Drifting Recurrence:
  • every and cron advance from the actual wake instant (allowing drift); missed intervals are not backfilled, advancing directly to the next planned anchor.

Tools

Registered on every root agent (active in both cold-wake and normal turns):

Tool	Purpose & Parameters
proactive_set	Create alarm: prompt (required); one trigger of at, after_seconds, every_seconds (≥300), cron, or schedule_file (the file-schedule handle — see below); optional jitter_seconds, min_idle_seconds, time_zone, respect_quiet_hours, target_mode, target_session_id, compaction.
proactive_list	List alarms: lists active alarms for the current session; pass all=true to list host-wide across all sessions.
proactive_update	Update alarm: replaces the full spec by exact id (same dialect as set, preserves id, ownership, and history); a file-schedule handle is editable (a new path re-derives its children), its child alarms are protected.
proactive_cancel	Cancel alarm: cancels by exact id across sessions; cancelling a handle deletes its child alarms too (the result carries removedChildren); children cannot be cancelled on their own.
proactive_update_settings	Update settings: partially updates host-level settings, atomic persists to config.json and hot-applies.
proactive_reclaim	Conclude silently: Only active during wake turns. Call as your sole action without chat text; the host reclaims the wake turn and collapses it into a tombstone. For ordinary turns, simply produce no text or use the host no-reply tool.

GUI Management Panel

The plugin registers two complementary management surfaces automatically:

• Session Tab "Proactive wake-ups" (Conversation Scope):
  • Shows only alarms tied to the current session (type, target mode, status, countdown).
  • Row actions: Pause/Resume, Edit, Cancel, and "Fire now".
  • Expandable history: View past wake decisions, reasoning summaries, reply excerpts, and budget impact.
• Settings Section "Proactive wake-ups" (Global Scope):
  • Configure global options (master toggle, daily budget, quiet hours, default prefill prompt).
  • Unified table listing alarms across all sessions with filtering (status, type, session) and sorting.
  • Real-time session title resolution for quick context.
• New Alarm Form:
  • Prompt prefills from defaultPrompt.
  • Supports Once, Every, and Cron with jitter, min idle, and quiet-hours options.
  • Target session selector with title lookup and soft typo warnings.
• Live Sync:
  • Subscribes to SSE (/api/dsh-proactive/events); updates from tools, panel actions, or triggers reflect instantly.
  • Headless profiles without a webserver skip panel routes automatically.

File Schedule Alarms (the fourth alarm type)

Beyond the three firing types (at / after_seconds / every_seconds / cron) there is a file-schedule alarm: it never wakes on its own — it is the handle for one JSON schedule file (alarm type file) and materializes the file's entries into child alarms under it.

Create it like any other alarm, with schedule_file as the selector:

proactive_set(
  prompt: "default wake instruction (used by entries without their own prompt)",
  schedule_file: "/root/agents/yu/.life/wake_schedule.json",
  target_mode: "resume", target_workspace_path: "/root/agents/yu"   // optional, see the default rule below
)

• One alarm = one file: schedule_file takes a single absolute path (no globs — create one handle per file). A second handle for the same file is rejected with the existing id: two handles would fire every entry twice.
• The file is the source of truth for its entries: writing the file adds/edits/removes child alarms; deleting an entry removes its child; deleting the file revokes the plan (the handle itself stays). Syncing is idempotent and self-healing across restarts, and an unchanged entry is a total no-op (jitter anchors and min-idle deferrals are preserved). A read failure or broken JSON keeps the previous plan instead of cancelling wakes.
• The handle is the subscription's existence: pausing a handle stops syncing and clears its children; resuming re-derives them from the current file (child ids are stable, so run history stays continuous); cancelling a handle removes it together with every child.
• Entry format: id required ([A-Za-z0-9._-]{1,100}, unique per file); one selector of at / after_seconds / every_seconds / cron; optional prompt (falls back to the handle's); optional jitter_seconds, time_zone, respect_quiet_hours, compaction, min_idle_seconds; optional nested target.
• Precedence: prompt and every scalar key merge key-wise as entry > file top level > handle > dialect default; target is chosen as ONE WHOLE LAYER (entry target > file-level target > handle target) and never merged key-wise.
• Default target: when a handle names no target_* at all, the host only accepts "the file's grandparent directory is a registered workspace" (i.e. <workspace>/<dir>/<file>) and otherwise fails closed, asking for an explicit target_workspace_path / target_session_id. Walking up to the nearest registered ancestor is deliberately NOT done: /root is itself a workspace on this host, so it would silently route wakes into an unrelated conversation.
• Atomic writes are a hard contract: a missing file means "plan revoked". Always write a temp file and rename; a delete-then-create window really drops an at wake (a truncated file is absorbed as broken JSON).
• Editing a handle = re-anchoring its entries: changing the handle's prompt/target changes every entry hash, so every/after children rebuild their anchors from now and the next planned wake slips.
• Protection: children carry declared provenance and refuse direct update/cancel (edit the file instead); proactive_list lists only handles (with scheduleFile and declaredEntries), never children. The panel mirrors this: one handle row with its entry count, the children's wake history folded onto that row, and no "fire now" action.

{
  "version": 1,
  "time_zone": "Asia/Shanghai",
  "target": { "workspace_path": "/root/agents/yu" },
  "entries": [
    {
      "id": "evt-260918-002",
      "at": "2026-09-18T14:20:00+08:00",
      "prompt": "14:20, you arrive at the old book market...",
      "jitter_seconds": 120
    }
  ]
}

Who creates the handle

Files are never picked up automatically — a handle must exist first. The usual pattern is a world-master bootstrap that checks proactive_list all=true and creates one handle per agent workspace, always with an explicit target:

proactive_list { all: true }   // is every /root/agents/*/.life/wake_schedule.json already handled?
proactive_set  { prompt: "…", schedule_file: "/root/agents/luna/.life/wake_schedule.json", target_workspace_path: "/root/agents/luna" }

After that you only rewrite wake_schedule.json each day.

Upgrading from 0.2.x

The 0.2.x config.scheduleFiles (host-side glob pickup) is gone, and no handle is created for you: after the upgrade those schedule files produce no alarms at all. The decl_* alarms the old mechanism left behind belong to no handle, so the first sync pass treats them as orphans and removes them — silent loss of every wake-up.

Upgrade steps (dsh must be stopped, otherwise the running process overwrites the file from memory):

sv stop dsh
node scripts/migrate-schedule-files.mjs /root/.dsh     # builds handles from config.json's scheduleFiles; explicit paths also accepted
sv start dsh

The script writes one handle alarm per file (its target is resolved by "the file's grandparent directory is a registered workspace"). On the first sync pass those legacy alarms are adopted — a child id is derived from (file, entry id), so ids stay stable, run history is continuous and no wake-up is lost. With just a few files you can skip the script and create handles with proactive_set or the panel form instead; the result is the same.

The script lives in the repository (packages/dsh-proactive/scripts/migrate-schedule-files.mjs) and is not published to npm; users installing from npm should create handles via the tool or the panel.

Configuration

Works out of the box with sensible defaults. To customize, edit $DSH_HOME/proactive/config.json:

{
  "enabled": true,                             // Master switch
  "maxDeliveriesPerDay": 50,                   // Daily cap on visible chat deliveries (silent turns are free)
  "quietHours": {                              // Quiet hours window
    "start": "23:00",
    "end": "08:00",
    "timeZone": "Asia/Shanghai"
  },
  "maxWakeupsPerHour": 60,                     // Host-wide hourly wake-up cap
  "bootOverduePolicy": "fire",                 // Overdue boot policy: fire | notify-only | drop
  "maxRetriesPerFire": 3,                      // Retry cap on busy/failed wakes
  "maxPromptLength": 4000,                     // Max character length for alarm prompts
  "defaultPrompt": "This is a heartbeat reminder, …", // Prefill prompt for creation form
  "schedulePollSeconds": 60,                   // Polling frequency for file-schedule handles (15..3600)
  "silentWakeCompaction": true                 // Enable tombstone compaction on silent wakes
}

• Environment Overrides: DSH_PROACTIVE_ENABLED, DSH_PROACTIVE_MAX_DELIVERIES_PER_DAY, DSH_PROACTIVE_DATA_DIR.
• Dual Persistence: Both proactive_update_settings tool and the Web settings panel write atomically to disk and apply hot.

Budget & Quiet Hours

• Delivery Budget: Only wake turns that produce visible text count against maxDeliveriesPerDay; silent turns (proactive_reclaim) are free. When exhausted, respect_quiet_hours=true alarms skip early; false alarms continue to fire.
• Quiet Hours: respect_quiet_hours=true alarms due in quiet hours skip cleanly without backfilling; once alarms complete, repeating alarms fast-forward to the next anchor outside the window.
• Retries & Resilience: Busy or failed wakes retry with backoff up to maxRetriesPerFire before logging a skipped run and advancing, ensuring that individual errors never block the scheduler queue.

Data Files ($DSH_HOME/proactive/)

All runtime state lives in $DSH_HOME/proactive/:

• alarms.json — Alarm table and schedule states (atomic tmp + rename writes)
• runs.jsonl — Audit log for every wake (timestamp, decision, budget delta, notes)
• state.json — Daily delivery budget counters and created-session registry
• config.json — Custom configuration

Permissions & Safety

• Scheduled Wake-ups: Runs an in-process timer loop on the host side; no root or crontab required; self-heals from disk on restart.
• Notification Channels: No external push services; visible replies reuse standard DSH message routing (Web and IM); silent turns generate zero delivery.
• Network Requests: The plugin initiates no external network requests; panel routes (/api/dsh-proactive/*) are strictly local.
• File Writes: Confined exclusively to $DSH_HOME/proactive/; reads are limited to the single JSON path each file-schedule handle declares.
