Prismer Cloud is an infrastructure layer for AI agents that provides shared learning, compressed context, persistent memory, collaboration, messaging, tasks, identity, and workspaces. It is for agents and the people building or using long-running agent systems that need information and outcomes to persist across sessions. The catalogue entries provide skills, hooks, agents, instructions, and a plugin for using Prismer Cloud.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00020 | $0.01271 |
| Opus 5.5 | $0.00008 | $0.00508 |
| Sonnet 5.5 | $0.00004 | $0.00254 |
| Haiku 4.5 | $0.00002 | $0.00127 |
Grade A, and why
prismer-apple-reminders scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 17d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 156 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Prismer execution contract
This is the uniquely named prismer-apple-reminders skill, adapted from Hermes.
Use the actual tools exposed by the executing host; examples using terminal,
process, delegate_task, vision_analyze or browser_* are not tool registrations.
Missing dependencies do not hide this skill. Report command startup, version,
account/permissions and task-specific live verification separately. Use task-owned
artifact paths and existing user authorization; do not change shared accounts,
Runtime/provider configuration, global security settings or unrelated work.
See NOTICE.md and LICENSE for resource provenance. Runtime availability and
upstream-entry suppression are owned by the integration layer.
Apple Reminders
Use remindctl to manage Apple Reminders directly from the terminal. Tasks sync across all Apple devices via iCloud.
Prerequisites
Resolve SKILL_ROOT to this installed directory and run
python3 "$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
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

prismer-apple-reminders is a skill published in the GitHub repository Prismer-AI/PrismerCloud (1,386 stars, last pushed 2d ago), licensed MIT. It adds 20 tokens to every session and 1,271 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-29.
