Drive Apple Reminders from the terminal via remindctl. Reminders sync across Apple devices through iCloud.

Setup check (lazy — do NOT probe every turn)

Do not run a remindctl status probe before each request. Just run the remindctl command the user asked for directly. Only when a command fails map the error to a Setup playbook branch:

• stderr contains command not found: remindctl → Setup playbook → "remindctl is not installed".
• output says permission denied / not determined / restricted → Setup playbook → "Reminders permission missing".
• macOS not detected → reply that this skill is macOS-only and stop. Do NOT try to install anything.

If unsure which branch applies, capture stderr and ask the user before proceeding.

Setup playbook (when prerequisites are missing)

When a check fails, the agent's job is to OFFER concrete help and EXECUTE the fix itself — not to dump install instructions on the user. Use this dialogue shape:

1. State plainly what is missing (one short reply).
2. Offer the most direct remediation the agent can perform via tools.
3. Wait for the user's yes/no reply.
4. On yes, execute the fix (the runtime approval gate will surface the command for confirmation).
5. Retry the original request; only then proceed.

remindctl is not installed

Reply (solo reply step):

"The remindctl utility is not installed. I can install it via Homebrew (brew install steipete/tap/remindctl) — it needs your confirmation and takes about 20 seconds. Install it?"

On yes:

[{ "tool": "os.shell.run", "args": { "cmd": "brew", "args": ["install", "steipete/tap/remindctl"] } }]

After install, retry the original command.

If brew itself is missing, do NOT attempt to bootstrap Homebrew — reply: "You don't have Homebrew installed. Install it manually from https://brew.sh/, then I'll continue."

Reminders permission missing

Unlike Notes Automation, remindctl has its own CLI command to request the permission — the agent CAN do it directly. Offer + execute:

"remindctl doesn't have permission to access Reminders. Request it now? A system dialog will appear — click "Allow" in it."

On yes:

[{ "tool": "os.shell.run", "args": { "cmd": "remindctl", "args": ["authorize"] } }]

Then re-run remindctl status to verify. If it still says denied, fall back to opening System Settings:

[{ "tool": "os.shell.run", "args": { "cmd": "open", "args": ["x-apple.systempreferences:com.apple.preference.security?Privacy_Reminders"] } }]

…and ask the user to flip the toggle for the terminal/agent process, then re-check.

When to use

• The user mentions "reminder" or "Reminders app".
• Creating personal to-dos with due dates that should appear on their iPhone / iPad.
• Listing or completing items in an Apple Reminders list.

When NOT to use

• Scheduling agent-driven background work — use the tasks.schedule / tasks.cron tools.
• Calendar events with a fixed start/end time and attendees — use a calendar skill.
• Project / engineering task management — use GitHub Issues, Notion, etc.
• If the user says "remind me" but actually means an in-agent alert, clarify before reaching for remindctl.

Common operations

All examples invoke os.shell.run with cmd: "remindctl" and the args array shown. Add ["--json"] to any read command for machine-readable output.

View

Goal	args
Today	["today"] (or just [] — today is the default)
Tomorrow	["tomorrow"]
This week	["week"]
Past due	["overdue"]
Everything	["all"]
Specific date	["2026-01-04"]
JSON output	append "--json" to any of the above
TSV output	append "--plain"
Counts only	append "--quiet"

Manage lists

Goal	args
List all lists	["list"]
Show items in a list	["list", "Work"]
Create a list	["list", "Projects", "--create"]
Delete a list	["list", "Work", "--delete"]

Create reminders

Goal	args
Quick add	["add", "Buy milk"]
Add with list and due	["add", "--title", "Call mom", "--list", "Personal", "--due", "tomorrow"]
Add with explicit datetime	["add", "--title", "Meeting prep", "--due", "2026-02-15 09:00"]

Complete / delete

Goal	args
Complete one or more by id	["complete", "1", "2", "3"]
Delete by id	["delete", "4A83", "--force"]

Date formats

Accepted by --due and date filters:

• Relative: today, tomorrow, yesterday
• Date: YYYY-MM-DD
• Date+time: YYYY-MM-DD HH:mm
• ISO 8601: 2026-01-04T12:34:56Z

Rules

1. When the user says "remind me", clarify: Apple Reminders (syncs to phone) vs an agent-driven alert (tasks.schedule / tasks.cron).
2. Always confirm reminder content, list, and due date with the user before creating or completing.
3. Prefer --json whenever you need to parse the output programmatically; the human-formatted view changes between releases.
