Reminder Skill
Create one-time reminder tasks using OpenClaw cron.
Usage
When user says "remind me to XXX in 30 seconds" or "remind me at 3pm", I create a cron job that executes the task and returns the result when the time comes.
Fixed Parameters
--session main - Use main session to inherit Discord context --system-event - System event payload for main session --channel discord - Discord channel --announce - Send result directly to Discord --delete-after-run - Delete task after execution
Dynamic Parameters (from current session context)
Use session_status tool to get current session's deliveryContext: --agent - Get from deliveryContext.accountId (e.g., machu) --to - Get from deliveryContext.to (e.g., channel:1476104553148452958) How to get: # Get current session info session_status # Output contains deliveryContext: # { # "channel": "discord", # "to": "channel:1476104553148452958", # "accountId": "machu" # }
Time Parsing
Parse user input time, support: Relative time: 30 seconds, 1 minute, 30 minutes, 2 hours, 1 day Absolute time: 3pm, 9am today, 12pm tomorrow Convert to ISO 8601 format for cron.
Usage Example
User says "remind me to check weather in 30 seconds": # 1. Get current session's deliveryContext session_status # Assume output: # { # "deliveryContext": { # "channel": "discord", # "to": "channel:1476104553148452958", # "accountId": "machu" # } # } # 2. Calculate time 30 seconds later date -u -d "+30 seconds" +"%Y-%m-%dT%H:%M:%SZ" # Result: 2026-02-26T13:30:00Z # 3. Create cron job (using main session + system-event) openclaw cron add \ --name "reminder-weather" \ --at "2026-02-26T13:30:00Z" \ --session main \ --system-event "Check Beijing weather" \ --agent machu \ --announce \ --channel discord \ --to "channel:1476104553148452958" \ --delete-after-run
Task Content (SECURITY)
User-specified task content must be sanitized before passing to cron: Validation Method: REJECT dangerous patterns (not escape) The script rejects any input containing: Command substitution: $(), backticks ` Shell metacharacters: ;, |, &, >, < Double quotes: " (breaks CLI quoting) Newlines: \n (can inject multiple commands) Dangerous command prefixes: sudo, rm, wget, curl, bash, etc. Sanitization Script: Use scripts/sanitize-message.sh to validate input: ./scripts/sanitize-message.sh "user's task content" # Exit code 0 = safe, non-zero = rejected If rejected: Tell user the task contains invalid characters and ask them to rephrase without: $() ` ; | & > < " or dangerous commands.
Confirmation Reply
After creating the task, reply to user to confirm: "OK, will remind you in X minutes/to do XXX" Don't tell user the specific cron command
Notes
Time must be in the future, not the past Task content should be concise and clear If time exceeds 48 hours, suggest using calendar Always use --session main + --system-event for reliable Discord delivery Validate task content with sanitize-message.sh before creating job
Category context
Messaging, meetings, inboxes, CRM, and teammate communication surfaces.
