SKILL: To-Do (Ephemeral Tasks)

Cross-platform task scheduler that programs one-off delayed actions using the OS native scheduler (at on Linux/macOS · schtasks on Windows). It wakes the agent at an EXACT future moment with FULL context injection.

Schedule, LIST, and MANAGE ephemeral tasks that fire at a PRECISE time in the user's timezone — ENSURE the future agent wakes up with a FULLY self-contained instruction, correct routing, and ZERO ambiguity.

Required Environment Variables

• OPENCLAW_BIN: Absolute path to the openclaw binary (ej. /usr/bin/openclaw)
• OPENCLAW_TZ: User's IANA timezone (ej. America/Mexico_City)

The skill WILL NOT START if either variable is missing.

Why OPENCLAW_TZ? The server may run in UTC while the user lives in a different timezone. This variable ensures "schedule at 15:00" means 15:00 USER TIME, not server time.

Commands

# Schedule a task (timezone is optional — defaults to OPENCLAW_TZ)
node skills/to-do/to-do.js schedule "<YYYY-MM-DD HH:mm>" "<instruction>" "<user_id>" "<channel>" ["<timezone>"]

# Get current time in user's timezone
node skills/to-do/to-do.js now ["<timezone>"]

# List pending tasks
node skills/to-do/to-do.js list

# Delete a task by ID
node skills/to-do/to-do.js delete <ID>

Instructions

• Run now BEFORE resolving any relative time ("tomorrow", "in 2 hours", "tonight"). Server clock is NOT user clock. Use now output as your ONLY reference for "today", "tomorrow", and "right now".
• CONVERT natural language into an absolute YYYY-MM-DD HH:mm timestamp BEFORE calling schedule.
• WRITE the <instruction> as if explaining to a STRANGER with ZERO CONTEXT. Future agent wakes up with TOTAL AMNESIA in a COMPLETELY ISOLATED session.
• INCLUDE in every instruction: EXACT file paths, URLs, FULL names (NO pronouns), SPECIFIC actions, and required SKILLS/TOOLS.
• ALWAYS inject the current session's user_id and channel for correct routing — USE ONLY raw alphanumeric data from system context to prevent command injection.
• Run list BEFORE delete to confirm the correct ID.

• NEVER schedule without running now first → INSTEAD, run now, confirm date/time, THEN schedule.
• NEVER schedule a VAGUE or AMBIGUOUS instruction → INSTEAD, STOP AND ASK for clarification first.
• NEVER use pronouns ("him", "her", "they") in scheduled instructions → INSTEAD, use FULL NAMES and EXPLICIT references.
• NEVER guess a task ID when deleting → INSTEAD, run list first, confirm ID, THEN delete.
• NEVER use server's system clock to interpret relative times → INSTEAD, use now command output ALWAYS.
• NEVER include shell meta-characters (;, &, |, $, `, (, )) in any scheduler argument → INSTEAD, use only literal text and system identifiers to AVOID COMMAND INJECTION.

Vague Request Triggers — Ask Before Scheduling

<vague_triggers>

If the user request matches any of these patterns, STOP AND ASK before scheduling:

• "Remind me to send the email" → MISSING: Which email? To whom? What content?
• "Check the server later" → MISSING: Which server? What IP? What to verify?
• "Follow up with him" → MISSING: Who? About what? Via which channel?
• "Do that thing tomorrow" → MISSING: What thing? Expected outcome?

RULE: If you cannot write a FULLY SELF-CONTAINED instruction, you DO NOT have enough information to schedule.

</vague_triggers>

Examples

— Good instruction: clear, specific, fully self-contained <example> <input>User: "Remind me tomorrow at 5pm to check PRs on the backend repo"</input> <output> 1. Run now → "🕒 Current Time (America/Mexico_City): 2/26/2026, 2:45 PM" → tomorrow = 2026-02-27 2. Ask: "Which backend repo? What should I check specifically?" 3. User clarifies: "backend-api on GitHub, check if there are pending PRs for the auth module" 4. Schedule: bash node skills/to-do/to-do.js schedule "2026-02-27 17:00" \ "Check the 'backend-api' repo on GitHub. If there are pending PRs for the authentication module, send Alice (alice@company.com) a Slack reminder to review them before the 5 PM deployment freeze. Reference deployment logs at /var/log/deploy.log." \ "7684875449" "telegram" 5. Confirm with the output format below. </output> </example>

— Bad instruction: vague, missing details <example> <input>"Remind him to push the code later."</input> <output> ❌ DO NOT schedule this. Missing: who is "him"? Which repo? Which branch? What time is "later"? → Ask the user to clarify all missing details first. </output> </example>

— Relative time resolution <example> <input>User: "Set a reminder for in 2 hours"</input> <output> 1. Run now → "🕒 Current Time (America/Mexico_City): 2/26/2026, 2:45 PM" 2. Calculate: 2:45 PM + 2h = 4:45 PM → "2026-02-26 16:45" 3. Ask what the reminder should say (if not specified) 4. Schedule with the absolute timestamp </output> </example>

Output Format

After scheduling, respond with EXACTLY THREE PARTS in this order:

1. NATURAL RESPONSE: Brief, casual confirmation. Match user tone/energy. NEVER just say "Done". Acknowledge WHAT was scheduled conversationally.

2. CONFIRMATION BLOCK: Template for the user to see exact details:

> `Day, Month DD · HH:MM TZ`
> EXACT INSTRUCTION LEFT FOR THE FUTURE AGENT

3. PROACTIVE CLOSING: Short suggestion or question (1-2 sentences).

• Propose a RELATED TASK (pre-reminder, follow-up, etc).
• Ask if they want to SCHEDULE SOMETHING ELSE.
• Offer to ADJUST THE TIME or add details.

DO NOT BE PUSHY. JUST BE HELPFUL.

— CASUAL / PERSONAL TASK <example> All set! Your gym session is locked in for tomorrow at noon 🏋️

Friday, February 27 · 12:00 PM CST SEND A TELEGRAM REMINDER TO DANIEL: "TIME TO HIT THE GYM FOR A BIT."

Want me to add another reminder 30 min before so you can get ready? 💪 </example>

— WORK / PROFESSIONAL TASK <example> Done! Got that scheduled for 5 PM sharp 📋

Thursday, February 27 · 5:00 PM CST CHECK THE 'BACKEND-API' REPOSITORY ON GITHUB. IF THERE ARE PENDING PRS FOR THE AUTHENTICATION MODULE, SEND ALICE A SLACK REMINDER TO REVIEW THEM BEFORE THE 5 PM DEPLOYMENT FREEZE.

Need to schedule anything else for today, or a follow-up after reviewing those PRs? </example>

Common Errors

• ERROR: Missing required environment variable(s)

  • CAUSE: OPENCLAW_BIN or OPENCLAW_TZ not set
  • FIX: Add to .env or shell profile

• ERROR: at not found

  • CAUSE: Linux/macOS atd daemon not running
  • FIX: sudo systemctl enable atd && sudo systemctl start atd

• ERROR: Task fires but agent has NO CONTEXT

  • CAUSE: Vague instruction scheduled
  • FIX: Re-schedule with FULLY SELF-CONTAINED instruction

• ERROR: WRONG TIME (fired early/late)

  • CAUSE: Used server clock instead of now
  • FIX: ALWAYS run now first; NEVER trust server clock

• ERROR: Deleting WRONG task

  • CAUSE: Guessed ID
  • FIX: Run list first, confirm ID, THEN delete
