What it does

Prismer Apple Reminders is an agent skill from Prismer-AI/PrismerCloud. Apple Reminders via remindctl: add, list, complete.

Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including scripts (for example `NOTICE.md` and `scripts/readiness.py`).

It sits in Productivity & Automation. The licence is MIT.

When your agent uses it

  • Productivity & Automation work in your project

Example prompts

  • “/prismer-apple-reminders”

Requirements

  • Python 3

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Clarify Apple Reminders versus an agent scheduled task only when intent is ambiguous.
  2. Use the user's stated content/time authorization; clarify only missing fields.
  3. Use --json for programmatic parsing
  4. Record host timezone and resolved timestamp. Read back the exact created ID;

What it can do on your machine

Read from SKILL.md and the folder at commit 0d240dd. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 1 file in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • python3
    • brew

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Prismer Apple Reminders loads about 1.3k tokens when it runs. Until then it costs about 19 tokens; SKILL.md has 489 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~19
When it runs · the whole SKILL.md, loaded when a task matches
~1.3k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

Prismer execution contract

This is the uniquely named prismer-apple-reminders skill, adapted from Hermes. Use the actual tools exposed by the executing host; examples using terminal, process, delegate_task, vision_analyze or browser_* are not tool registrations. Missing dependencies do not hide this skill. Report command startup, version, account/permissions and task-specific live verification separately. Use task-owned artifact paths and existing user authorization; do not change shared accounts, Runtime/provider configuration, global security settings or unrelated work. See NOTICE.md and LICENSE for resource provenance. Runtime availability and upstream-entry suppression are owned by the integration layer.

Apple Reminders

Use remindctl to manage Apple Reminders directly from the terminal. Tasks sync across all Apple devices via iCloud.

Prerequisites

Resolve SKILL_ROOT to this installed directory and run python3 "$SKILL_ROOT/scripts/readiness.py" reminders, then remindctl --version. The startup probe does not authorize EventKit or verify iCloud/notifications. The audited 0.1.1 lacks --alarm: enable the alarm examples below only when the installed add/edit help explicitly supports that flag. Otherwise report the early-notification requirement blocked; do not silently substitute a due date.

  • macOS with Reminders.app
  • Install: brew install steipete/tap/remindctl
  • Grant Reminders permission when prompted
  • Check: remindctl status / Request: remindctl authorize

When to Use

  • User mentions "reminder" or "Reminders app"
  • Creating personal to-dos with due dates that sync to iOS
  • Managing Apple Reminders lists
  • User wants tasks to appear on their iPhone/iPad

When NOT to Use

  • Scheduling agent alerts → use the actual Prismer task scheduler, not an invented cronjob tool
  • Calendar events → use Apple Calendar or Google Calendar
  • Project task management → use GitHub Issues, Notion, etc.
  • If user says "remind me" but means an agent alert → clarify first

Due Time vs Alarm / Early Nudge

When the installed version supports both, --due and --alarm are different fields:

  • --due sets the reminder's due date/time.
  • --alarm sets the EventKit alarm/notification trigger. Timed due reminders may default to an alarm at the due time, but pass --alarm explicitly when the user asks for an earlier nudge.

For a reminder due at 2:00 PM with a notification 30 minutes earlier:

bash
remindctl add --title "Hairdresser" --due "2026-05-15 14:00" --alarm "2026-05-15 13:30"

To edit an existing reminder:

bash
remindctl edit 87354 --due "2026-05-15 14:00" --alarm "2026-05-15 13:30"

The Reminders UI may show or group the item by the alarm time because that is when the notification fires. Verify with JSON instead of assuming the due time moved:

bash
remindctl today --json

Read the actual version's JSON schema; the following fields are version-dependent:

  • dueDate: actual due time
  • alarmDate: notification / early nudge time

Apple's public EKReminder docs list only reminder-specific properties. Alarm support comes from inherited EKCalendarItem behavior exposed by remindctl's --alarm flag.

Complete / Delete
bash
remindctl complete 1 2 3          # Complete by ID
remindctl delete 4A83 --force     # Delete by ID
Output Formats
bash
remindctl today --json       # JSON for scripting
remindctl today --plain      # TSV format
remindctl today --quiet      # Counts only

Date Formats

Accepted by --due and date filters:

  • today, tomorrow, yesterday
  • YYYY-MM-DD
  • YYYY-MM-DD HH:mm
  • ISO 8601 (2026-01-04T12:34:56Z)

Rules

  1. Clarify Apple Reminders versus an agent scheduled task only when intent is ambiguous.
  2. Use the user's stated content/time authorization; clarify only missing fields.
  3. Use --json for programmatic parsing
  4. Record host timezone and resolved timestamp. Read back the exact created ID; help/JSON success alone does not prove the notification was delivered.
