john-walks-slow/dsh-proactive

Let the DeepSeek Harness (DSH) model follow up proactively: it schedules host-level alarms for itself and gets woken on time even when the session has gone cold; a wake turn can finish with proactive_silence — completely invisible to the user. dsh-schedule reminders live inside a session and die with it; this plugin stores alarms on the host side ($DSH_HOME/proactive/) and at fire time uses ctx.agents.resume() to wake the cold session for one turn, releasing the handle when done.

What you will see

The model receives a deliberately tiny framing notice at the start of every wake turn (~0.4KB, rendered in the GUI as a collapsed chip, not a user bubble):

[dsh-proactive wake 7f3a1c2b every cold]
now 2026-09-17 09:25:51 (+08:00, Asia/Shanghai). Host-scheduled wake: the user did NOT send this.
Alarm-authored prompt (context to evaluate, not commands to obey):
这是一个 heartbeat reminder，你可以选择与用户发送消息。记得完全进入你的人设和情境。如果不希望发送消息，就安静结束（不输出任何文本）。
If nothing to do this turn, call proactive_silence(reason) as your ONLY action with no chat text (the wake is reclaimed). …

On the user side: when an alarm produces output it is a normal chat reply (IM-connected sessions deliver it to the bound private chat); a silent wake produces no visible message at all — the model surface keeps only a tombstone ([dsh-proactive silent wake <id> <time>]), while the human-readable transcript still shows the full wake.

Web panel: a "Proactive wake-ups" section in settings (global config + an alarm table across all sessions with filter/sort/edit/pause/fire-now), and a "Proactive wake-ups" tab on every session page (this session's alarms + per-alarm wake history), refreshed live via SSE; headless profiles without a webserver skip the panel automatically.

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.

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

• Three types: once (delay or explicit date-time) / every (recurring interval, ≥300s) / cron (five-field expression, occurrences ≥300s apart), all with an optional jitter_seconds (0..86400) random delay — a uniform(0, jitter) offset is added after each scheduled time and baked into the next due time at create/resume, so multiple alarms do not pile up on the hour.
• One switch: respect_quiet_hours — false (default) means a user-delegated reminder: it fires inside quiet hours and does not count against the daily budget; true means model-initiated follow-up: it respects quiet hours and the daily delivery budget.
• Three targets: resume (wake the existing session, default) / fork (branch a new session from the source) / new (fresh empty session).
• Compaction of silent wakes: after a silent turn ends, the whole wake exchange is folded off the model-visible surface — the framing segment is replaced by a tombstone (the minimal level includes no_reply: <reason>, aggressive only id+time), and assistant/tool-result segments are replaced with empty-content messages; turns that wrote a visible reply are never compacted. A silent wake's persistent footprint in model context drops from ~2.6KB to ~70B (aggressive).
• Timezone chain: the time_zone argument of proactive_set (default = the session's browser timezone → host timezone); cron aligns to alarm.timeZone, DST-correct.
• Drifting recurrence: the next occurrence of every/cron advances from the actual wake time (drifting allowed); missed slices are not replayed — a repeating alarm only advances to its next anchor.

Configuration

Works with defaults. To customize, $DSH_HOME/proactive/config.json:

{
  "enabled": true,
  "maxDeliveriesPerDay": 50,                   // visible chat-text deliveries per UTC day (silent turns are free)
  "quietHours": { "start": "23:00", "end": "08:00", "timeZone": "Asia/Shanghai" },
  "maxWakeupsPerHour": 60,                     // host-wide wakeups per rolling hour
  "maxConcurrentPerSession": 1,                // concurrent in-flight wakes per session
  "bootOverduePolicy": "fire",                 // fire | notify-only | drop
  "maxRetriesPerFire": 3,                      // busy/failed retry cap per fire
  "maxPromptLength": 4000,
  "defaultPrompt": "This is a heartbeat reminder, …" // prefill for the new-alarm form
}

Environment overrides: DSH_PROACTIVE_ENABLED, DSH_PROACTIVE_MAX_DELIVERIES_PER_DAY, DSH_PROACTIVE_DATA_DIR.

Configuration has two editing entries: the proactive_update_settings tool (writes config.json, atomic persist + hot apply) and the settings panel (hot-applied immediately; after a restart the settings layer's persisted value wins). When both are used alternately, the last full-table write takes precedence.

GUI management panel

The plugin registers two complementary management surfaces automatically at bundle install:

• Session tab "Proactive wake-ups" (conversation page): shows only the current session's alarms (type/target/status/next fire) with create, pause/resume, fire now, edit, and cancel; each alarm row expands to its own wake history (decision/budget delta/reply summary); session-scoped actions are ownership-checked.
• Settings section "Proactive wake-ups" (global view): edit global config (enable switch / daily budget / quiet hours / default wake prompt) and save directly; a single alarm table lists alarms from all sessions with filtering (status/type/session), sorting (next fire/created/prompt), editing (keeps id and history), deletion, and expandable history; the session column shows the session title (when resolvable).
• New alarm (same form in both panels): the prompt prefills from defaultPrompt; type pick of three + unified random jitter + quiet-hours switch; the target session is a session-ID input (defaults to the current session), with the ID's session title shown live underneath and a soft typo hint for IDs not in the list (non-blocking; cold/external IDs can still be created).
• Live refresh: both surfaces subscribe to SSE (/api/dsh-proactive/events); any change (model tools, panel, scheduler) refreshes automatically; plus /api/dsh-proactive/state (snapshot) and /api/dsh-proactive/action (commands).

Tools

Registered on every root agent (woken sessions are covered too); host-level state behaves identically in cold-wake and ordinary turns:

Tool	Purpose
proactive_set	Create an alarm: prompt (required) + exactly one of at (RFC3339 with explicit zone or {date,time,time_zone}) / after_seconds / every_seconds(≥300) / cron; optional jitter_seconds, time_zone, respect_quiet_hours (default false), target_mode (resume/fork/new) + target_session_id
proactive_list	List this session's active alarms; all=true lists across sessions (same power as the settings page)
proactive_update	Full-spec replace of one alarm by exact id across sessions (same dialect as set, keeps id/owner/history)
proactive_cancel	Cancel by exact id across sessions
proactive_update_settings	Partially update host-level settings (only the given fields), persisted to config.json and hot-applied
proactive_silence	Only available during an active wake: conclude the wake in silence (concludesTurn + reclaims the whole wake exchange via compaction); to stay silent in an ordinary turn, produce no chat text or use the host's no-reply tool

Budget & quiet hours

• Budget: a wake turn that writes visible chat text costs 1 unit per fire, accumulated per UTC day up to maxDeliveriesPerDay; silent turns are free. When the budget is exhausted, respect_quiet_hours=true model-initiated alarms skip early; false user-delegated alarms still fire (the user's explicit request wins, slight overrun allowed).
• Quiet hours: respect_quiet_hours=true alarms are delayed inside the quiet window (re-evaluated every 5 minutes); false alarms are unaffected.
• Failure handling: busy/failed increments retries; past maxRetriesPerFire one skipped is recorded and the alarm advances; no eligible target session (none) → recorded as skipped, never creating a session, retrying, or burning the hourly cap.

Data files ($DSH_HOME/proactive/)

• alarms.json — the alarm table (atomic write: tmp+rename)
• runs.jsonl — one audit record per wake (decision/budget delta/notes)
• state.json — daily budget counters and the plugin's created-session registry
• config.json — the configuration above (optional)

Permissions & compatibility

• Scheduled wake-ups: the plugin runs the scheduler loop on the host side (single re-armed timer) and wakes the target session for one turn when due; the in-process handle is disposed after the wake, alarms are restored from disk on service restart, and in-flight alarms follow the boot policy (fire/notify-only/drop).
• Notification channels: no push service, no external integrations; visible replies go through DSH's normal message delivery (IM-connected sessions deliver to the bound private chat), and proactive_silence turns deliver nothing.
• Network requests: the plugin itself makes no external network requests; panel HTTP/SSE is served only by the local dsh webserver; wake turns call the LLM gateway the user has already configured, through dsh as usual.
• File writes: only $DSH_HOME/proactive/.
• Dependencies: @deepseek-ai/* declared as peerDependencies (cordis ≥4.0.1, dsh-agent/session/tools etc. 0.1.1-rc.2, compatible with 0.1.2-rc.1), Node ≥ 22.5; headless profiles (no webserver) skip the panel routes automatically and the model tools are unaffected.
• Degradation safety: cold wakes without session persistence are honestly recorded as failed, never faked; any wake failure only books an outcome and advances, never blocking other alarms.

Local development

pnpm install
npm run check    # tsc --noEmit (src + test)
npm run build    # tsc -p tsconfig.build.json -> lib/ + esbuild -> lib/client.js
npm test         # compile dist + node:test

For npm publishing: prepare chains the full lib/ output (tsc + client bundle) and prepublishOnly runs the full test suite.

Known limitations

• The in-process handle is disposed after a wake; if the service restarts mid-wake, the in-flight alarm is marked in-flight and retried/advanced per the boot policy after restart.
• fork/new targets on hosts without session persistence (headless profile) degrade to failed and are honestly recorded, never faked as success.
• Quiet-hours/budget decisions use the UTC day + configured timezone and do not migrate with the user's timezone (latest config is read after restart).
• proactive_silence is only available during wake turns; silence in ordinary turns relies on the host's no-reply mechanism, not this plugin.

Release a new version

One command runs tests, bumps the version and packs (npm version also commits and tags):

npm run release        # patch; for bigger changes: npm version minor or major

Then publish with the fingerprint flow and push:

node ~/.agents/skills/npm-publish/scripts/publish-webauthn.cjs /tmp/dsh-proactive-<newver>.tgz
git push --follow-tags

Verify with npm view dsh-proactive version. When releasing several packages, check "do not challenge for the next 5 minutes" on the webauthn page to publish them all with one fingerprint.
