synced Oct 26, 2026Automizer for Claude Desktop
Reliably modify, queue, and manage scheduled tasks for the Claude Desktop App — from inside the app, externally via CLI, or when the app is closed.
Language: English | Deutsch
[!NOTE] AI / LLM Agent Ready: A structured, machine-readable overview for LLM agents is available at

[!IMPORTANT] Unofficial Community Tool. This project is an independent community utility and is not affiliated with, endorsed, or audited by Anthropic. "Claude" and "Claude Desktop" are trademarks of Anthropic and are used here solely for descriptive purposes to identify compatible software.
It reads and writes local configuration files created by the Desktop App. Their format is undocumented and subject to unannounced changes across app releases. Backups are automatically created before every write operation. Use at your own risk.
Quick Navigation
01. Architecture & Queueing Workflow
Automizer orchestrates task mutations through a decoupled staging queue. This architecture guarantees that active sessions are never interrupted while eliminating silent disk-write clobbering:
flowchart TD
subgraph AgentOrUser ["User / Agent Request"]
A["Request Task Change or Creation"] --> B["queue_request.py"]
end
subgraph CareQueue ["Pending Queue Layer"]
B --> C["_care/pending/pending-tasks.json"]
end
subgraph BackgroundMerger ["Background Merger (Scheduled Task)"]
D["apply_pending_tasks.py / VBS Wrapper"] --> E{"Is Claude Desktop Running?"}
C -. Reads Pending Requests .-> D
E -- "Yes (Process Running)" --> F["Skip / Defer Execution"]
E -- "No (App Closed)" --> G["Backup Registry & Create Skill Directory"]
G --> H["Atomically Update scheduled-tasks.json"]
H --> I["Log to _care/history/applied-tasks.json"]

03. The Challenge
The Claude Desktop App manages its scheduled tasks across two separate storage locations:
| Component | Path | Description |
|---|---|---|
| Task Prompt | <Documents>/Claude/Scheduled/<slug>/SKILL.md | Contains the prompt instructions to execute |
| Task Registry | <AppData>/Claude/local-agent-mode-sessions/<session>/<account>/scheduled-tasks.json | Stores schedules (cronExpression), enabled state, and permissions |
Both components are required for a functional task. Simply creating the prompt folder is insufficient: without a corresponding registry entry and valid cronExpression, the task will never trigger and won't appear in the app's schedule overview.
Crucially: The Desktop App maintains the task registry in memory and writes it back to disk upon session exit. Any direct modifications made to scheduled-tasks.json while the app is active will be silently overwritten and lost without warning.
04. The Solution
Automizer decouples change requests from disk-write operations through a staged queue:
Queue Request (anytime, in-app or from external agents)
│
▼
pending-tasks.json ──▶ apply_pending_tasks.py ──▶ Is Claude Desktop Running?
│
yes ────────────┤ skip and retry next cycle
│
no ─────────────┴─▶ Backup → Write →
Verify → Log Report
Modifications take effect with a deliberate delayed execution. This prevents silent overwrites, avoids race conditions, and provides an auditable history of applied changes.
05. Key Capabilities & Safety Invariants
| Capability | Technical Mechanism | Security & Reliability Invariant |
|---|---|---|
| Process Discrimination | Inspects binary path (*WindowsApps*) rather than just process name | Distinguishes Desktop App from Claude Code CLI (claude.exe) without false lockouts (INV-PROC-04) |
| Decoupled Staging Queue | Atomically appends requests to _care/pending/pending-tasks.json | Non-blocking write isolation; safe to enqueue mutations from active Claude sessions (INV-QUEUE-03) |
| Automated Pre-Write Snapshots | Backs up scheduled-tasks.json with timestamped snapshot before writing | Zero data loss; automated recovery rollback capability on malformed edits (INV-BACKUP-05) |
| Post-Write Readback Verification | Re-parses JSON and verifies keys immediately after file writes | Guarantees registry integrity before clearing queued mutation requests (INV-VERIFY-06) |
| Strict Field Whitelisting | Whitelists allowed schema keys (cronExpression, enabled, model, etc.) | Prevents tampering with internal paths or unvalidated configuration fields (INV-ACD-04) |
| Self-Protection Guard | Rejects requests disabling tasks matching CDA_SELF_PROTECT_PREFIX | Prevents automated agents from accidentally disabling supervisory maintenance tasks (INV-ACD-04) |
| Cross-Host Isolation | Filters pending requests by matching local hostname | Safe synchronization across multi-device OneDrive environments (INV-HOST-07) |
| Zero-Egress & Standard Library | 100% Python standard library with zero external dependencies | Completely offline; zero telemetry, zero analytics, zero network exposure (INV-LOCAL-01) |
| Windowless Background Runner | Windows Script Host VBScript runner with WScript.Shell.Run(cmd, 0, False) | No console popups or focus-stealing flickers during background cycles (INV-WINDOW-08) |
| Audit Logging & History | Structured JSON report in _care/history/applied-tasks.json | Fully auditable mutation history with execution timestamp and status (INV-AUDIT-09) |
06. Target Personas & High-Intent SEO Queries
Automizer for Claude Desktop is purposefully engineered for four distinct technical profiles:
[PERSONA-01] Autonomous AI Agent & Claude Prompt Engineer
- Profile: Developers running autonomous agent loops (Claude Code CLI, OpenAI Codex CLI, Google Antigravity, Kimi Code) seeking to schedule periodic maintenance routines inside Claude Desktop.
- Pain Point: Modifying
scheduled-tasks.jsonfrom subagent processes while Claude Desktop is running causes immediate memory overwrite on app shutdown. - Solution: Enqueueing requests via
queue_request.pyensures scheduled routines are staged safely and merged during dormant intervals. - High-Intent Search Queries:
"claude desktop automate scheduled tasks","claude desktop schedule prompt via cli","programmatically add scheduled tasks claude desktop".
[PERSONA-02] Windows System Administrator & DevOps Engineer
- Profile: System engineers managing developer workstations who need reliable, headless automation under Windows without elevated privileges.
- Pain Point: Scheduled tasks that trigger CMD or PowerShell windows steal desktop focus, interrupting user keyboard and mouse activity.
- Solution: Automizer provides a native windowless VBScript runner (
run_apply_pending_hidden.vbs) and unprivilegedRunAsInvokerinstallation. - High-Intent Search Queries:
"claude desktop windows task scheduler hidden","run python scheduled task without console popup windows","claude desktop unattended task merger".
[PERSONA-03] Privacy-Conscious Developer & Local-First Builder
- Profile: Security professionals and developers working in air-gapped, zero-trust, or enterprise environments where third-party package supply chains are restricted.
- Pain Point: Tools requiring heavy third-party wheels or telemetric reporting introduce compliance risk and network egress liabilities.
- Solution: 100% Python standard library runtime (
INV-LOCAL-01), audited Level 1 SBOM, and zero external network sockets. - High-Intent Search Queries:
"claude desktop offline task scheduler","zero egress claude desktop automation","air gapped claude task manager python".
[PERSONA-04] Multi-Device Workflow Orchestrator
- Profile: Power users synchronizing development repositories and documents across multiple machines (e.g. Workstation and Laptop via OneDrive or Syncthing).
- Pain Point: Synchronization conflicts and tasks intended for a specific hardware node executing improperly on alternate hosts.
- Solution: Hostname-aware fail-closed queueing (
INV-HOST-07) isolates mutations so only the targeted host applies its designated tasks. - High-Intent Search Queries:
"claude desktop sync scheduled tasks onedrive","multi host task scheduler claude desktop","fail closed scheduled tasks multi device".

08. Three Operating Modes
Automizer adapts seamlessly to three operational environments:
| Mode | Context | Workflow | Prompt Template |
|---|---|---|---|
| 1. In-App | LLM running inside Claude Desktop | Append request to pending-tasks.json (delayed) | prompts/01_in-app_en.md |
| 2. External (Active) | External CLI / Agent, app is running | Enqueue request via queue_request.py (delayed) | prompts/02_from-outside-app-running_en.md |
| 3. App Closed | App is verified closed | Execute apply_pending_tasks.py (immediate) | prompts/03_app-closed_en.md |
09. Quickstart & Installation
Prerequisites: Python 3.8+. Zero third-party dependencies (standard library only).
# 1. Verify path detection across local installation
python tools/apply_pending_tasks.py --paths
# 2. Register hourly background merger task (Windows Scheduled Task, no admin needed)
powershell -ExecutionPolicy Bypass -File tools/install_merger_task.ps1
# 3. Acceptance test:
# a) Trigger while app is open -> changes deferred
# b) Close app and re-trigger -> changes safely merged
# c) Zero visible terminal flicker in background mode
[!TIP] Always execute the installer via
-File tools/install_merger_task.ps1rather than pasting snippet contents into PowerShell, ensuring$PSScriptRootresolves reliably.
10. Windowless Background Execution
Scheduled maintenance must never steal focus from active work. Standard Windows scheduled tasks executing Python or PowerShell often spawn transient console windows.
Automizer solves this cleanly via tools/run_apply_pending_hidden.vbs:
- Invokes the Windows Script Host shell with window style
0(SW_HIDE):WScript.CreateObject("WScript.Shell").Run cmd, 0, False - Subprocesses spawned by Python internal checks utilize
subprocess.CREATE_NO_WINDOW(0x08000000). - The resulting background merge execution is 100% invisible, flicker-free, and non-intrusive.
11. Tooling Overview & Path Resolution
| Script | Purpose |
|---|---|
tools/claude_desktop_paths.py | Dynamic path resolution for Documents, registry files, and process detection |
tools/queue_request.py | CLI utility for enqueueing set or create requests into pending queue |
tools/apply_pending_tasks.py | Safe merger engine: verifies app state, backs up registry, merges changes, logs |
tools/install_merger_task.ps1 | PowerShell installer registering scheduled background merger |
tools/run_apply_pending_hidden.vbs | Windowless VBScript launch wrapper |
Robust Path Resolution
On Windows, the Documents folder may be redirected to OneDrive (Known-Folder-Move). Automizer queries the Windows User Shell Folders registry key (Personal) rather than guessing %USERPROFILE%\Documents. Session GUIDs in AppData are scanned dynamically to select the latest active session.
12. Safety Guarantees & Safeguards
- Path-Based Process Detection: Distinguishes the Claude Desktop Windows Store app (
*WindowsApps*) from the Claude Code CLI (claude.exe) to prevent false-positive lockouts. - Field Whitelisting: Strict schema whitelist (
cronExpression,enabled,model,userSelectedFolders,permissionMode,disableJitter). - Self-Protection Guard: Rejects requests attempting to disable maintenance tasks (prefix customizable via
CDA_SELF_PROTECT_PREFIX). - Pre-Write Backups & Post-Write Verification: Automatic snapshot created before every modification, followed by immediate readback verification.
- Fail-Closed Cross-Host Isolation: Pending wishes tagged with foreign host identifiers in multi-device OneDrive setups are preserved rather than consumed locally.
- No Silent Drops: Rejected or malformed wishes are logged with clear diagnostic rationale.
13. Optional Self-Administration Skill
This repository provides two independent layers:
- The Core Engine (
tools/,prompts/) — Queueing mechanism and atomic merger for humans and external agents. - The Self-Administration Skill (
skill/self-administration-of-scheduled-tasks/SKILL.md) — An instruction framework enabling Claude Desktop tasks to maintain, monitor, and optimize themselves through five modular supervisory roles.
14. Terminology
| Term | Definition |
|---|---|
| Slug | Short task identifier matching folder name under Scheduled/<slug>/ and id in the task registry |
| Wish / Request | A pending mutation record in pending-tasks.json awaiting application |
| Merger | apply_pending_tasks.py engine applying queued requests when the app is inactive |
| Registry | The scheduled-tasks.json configuration store inside Claude AppData |
| Session GUID | Dynamic session identifier folder located below local-agent-mode-sessions/ |
15. Privacy & Local-First Execution
Automizer operates 100% locally. It never communicates over external networks, sends zero telemetry, and requires no API keys or credentials.
pending-tasks.json, applied-tasks.json, and local logs are strictly excluded via .gitignore to safeguard system paths and custom prompt instructions.
