## Documentation

### 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
