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 | $0.00059 | $0.00539 |
| Opus 5.5 | $0.00024 | $0.00216 |
| Sonnet 5.5 | $0.00012 | $0.00108 |
| Haiku 4.5 | $0.00006 | $0.00054 |
Grade A, and why
nucleus-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 1mo 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.
What it actually says
Use nucleus-apple reminders ... to inspect and mutate Apple Reminders data.
Operating Stance
- Prefer the installed
nucleus-applebinary. - Fall back to
uvx --from nucleus-apple-mcp nucleus-apple ...when onlyuvxis available. - Prefer exact due or start windows and list filters over broad all-list reads when scope is known.
- Treat completion as the default state-changing operation; delete only for explicit removal.
- Read current reminder state before mutating ambiguous titles.
- Preserve date-only vs datetime semantics from the request.
- Re-read the affected query after moves, completion changes, and deletes when confirmation matters.
Core Workflow
- Resolve source or list scope only as far as the task requires.
- Inspect reminders with the relevant date and status filters.
- Choose create vs update vs complete vs delete from
references/decision-rules.md. - Use
references/commands.mdfor canonical command shapes. - Use
references/failure-modes.mdwhen date boundaries, hidden lists, or null due or start fields matter.
Task Routing
- Due or start filtering, open vs completed views: read
references/decision-rules.md#date-filtering. - Create, edit, or move reminders: read
references/decision-rules.md#mutation-choice. - Mark complete, reopen, or delete: read
references/decision-rules.md#completion-vs-deletion. - Hidden lists, date-only surprises, status ordering, or null date fields: read
references/failure-modes.md.
Output / Escalation
- Use
--prettyonly for human inspection. - Use
--status allwhen the user cares about both open and completed reminders. - Prefer
--clear-*or--no-completedover reconstructing the full reminder payload.
What ships with it
4 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.

nucleus-apple-reminders is a skill published in the GitHub repository zish-rob-crur/nucleus-apple-mcp (23 stars, last pushed 1mo ago), licensed MIT. It adds 59 tokens to every session and 539 once invoked, about $0.0002 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 2026-08-30.
