Cron Delivery Fix

Diagnose and fix OpenClaw cron job message delivery failures. Uses scripted operations to prevent manual configuration errors.

Trigger Conditions

  • User reports "didn't receive scheduled task message"
  • Cron status shows delivered but user didn't receive it
  • Cron status shows not-delivered
  • Need to batch-check/fix all cron delivery configs

Core Lessons (Historical Incident Log)

This issue recurred on multiple dates. Each manual fix introduced new problems:

  1. Session context: Isolated session cron jobs lack contextToken, causing silent message failures
  2. Missing params: Some tasks were missing to/channel/accountId, resulting in incomplete delivery
  3. Config wipe: Manual --no-deliver accidentally cleared delivery configs; wrong --session caused invalid combinations

Root cause: Manually running openclaw cron edit one by one easily misses parameters or creates illegal configs.

Solution: Use scripts for unified management. Never manually edit cron session/delivery fields.

Delivery Config Specification

Valid Config Combinations

sessionTarget payload.kind delivery.mode Description
isolated agentTurn announce AI executes + cron auto-delivers summary (requires complete to/channel/accountId)
isolated agentTurn none AI self-delivers via message tool (must include send params in prompt)
main systemEvent none Triggers in main session (no independent delivery)

Invalid Configurations

Combination Error Reason
main + agentTurn Gateway rejects: main cron jobs require payload.kind="systemEvent"
announce + missing to No delivery target, message cannot be sent
announce + missing accountId Multi-account setups deliver to wrong account
none + agent in isolated session AI's message tool lacks contextToken in isolated session

Standard Template for Delivery Tasks

All cron jobs that need to send messages to users must have:

sessionTarget: isolated
payload.kind: agentTurn
delivery.mode: announce
delivery.channel: \x3Cyour-channel-id>
delivery.to: \x3Cyour-user-id>
delivery.accountId: \x3Cyour-account-id>

Standard Template for Silent Tasks

Tasks that don't need to send messages:

sessionTarget: isolated
payload.kind: agentTurn
delivery.mode: none

Operation Flow

Step 1: Diagnose

bash skills/cron-delivery-fix/scripts/diagnose.sh

Outputs delivery status of all cron jobs, flagging problematic ones.

Step 2: Fix

# Fix a single job
bash skills/cron-delivery-fix/scripts/fix-single.sh \x3Cjob-id> [--announce|--silent]

# Fix all delivery-type jobs
bash skills/cron-delivery-fix/scripts/fix-all.sh

# Restore a broken job (with valid config)
bash skills/cron-delivery-fix/scripts/restore.sh \x3Cjob-id>

Step 3: Verify

# Run diagnosis again to confirm no issues
bash skills/cron-delivery-fix/scripts/diagnose.sh

# Manual trigger test
openclaw cron run \x3Cjob-id>

Prohibited Operations

  1. Never manually use openclaw cron edit --session main on agentTurn-type tasks
  2. Never use --no-deliver to clear delivery config then re-add params one by one (easy to miss params)
  3. Never modify cron config without validating the combination is legal
  4. Never fix cron without running diagnose.sh to verify afterwards
Usage Guidance
Review carefully before installing. Only use this in an environment where you are prepared for the skill to modify OpenClaw cron jobs, and do not run the fix scripts until the destination channel, recipient, and account values are replaced with your intended values and you have exported or backed up existing cron configuration.
Capability Assessment
⚠ Purpose & Capability
The stated purpose of diagnosing and fixing OpenClaw cron delivery is coherent, but the implementation goes beyond diagnosis by bulk-editing cron jobs, forcing fixed delivery channel/recipient/account values, and potentially changing delivery behavior for unrelated jobs.
⚠ Instruction Scope
The skill instructs users to run fix-all and restore scripts, but it does not require a dry run, per-job selection, confirmation, rollback, or explicit user-supplied delivery destinations before persistent cron edits.
⚠ Install Mechanism
The package includes executable shell scripts and OpenClaw CLI mutation commands, while the skill metadata does not declare corresponding shell or cron-modification authority for user review.
⚠ Credentials
Access to scheduled-job delivery configuration is high impact because it can redirect or suppress automated messages; the hard-coded global settings are not proportionate for a generic delivery-fix tool.
⚠ Persistence & Privilege
The scripts make persistent cron configuration changes and provide verification, but no backup, transaction, or rollback path before applying bulk edits.
How to Use
  1. Make sure OpenClaw is installed (local or Docker)
  2. Run the install command in chat: /install cron-delivery-fix
  3. After installation, invoke the skill by name or use /cron-delivery-fix
  4. Provide required inputs per the skill's parameter spec and get structured output
