What it does

Enforces an on-device reminder engine where the local database is the only source of truth and the OS pending-notification set is a disposable cache reconciled through one idempotent syncNotifications() entrypoint; keeps flutter_local_notifications behind a single NotificationGateway port, all scheduling math pure and Clock-injected, recurring schedules stored as wall-clock + recurrence rule (never UTC instants) and resolved to a TZDateTime in tz.local for DST correctness, inexact-alarm default with SCHEDULE_EXACT_ALARM as an opt-in, iOS ~64-cap budgeting, isolate-safe…

What this skill changes about the agent has not been set out here as a list. Its SKILL.md, shown below, says it in the author’s own words.

The skill itself

A skill is instructions the model reads, so you can see what you are getting: below is the start of its SKILL.md. The front matter loads with every session, the body loads when the skill triggers, and the whole file comes with the install.

17# Local Notifications Scheduler
18
19One on-device reminder engine, owned centrally, with a narrow API. The local DB is the source of truth; the OS pending set is a disposable cache. Every scheduling change flows through one pure-then-reconcile path so the whole engine is verifiable off-device. Applies whenever you schedule, cancel, or reason about local notifications.

21Read the reference for the task at hand:
22- references/notification-gateway-port.md — the port contract, the two adapters, channels/grouping/deep-link payload rules.
23- references/scheduler-and-recurrence-rules.md — pure ReminderScheduler.compute diff, recurrence/DST math, deterministic IDs, budgeting, the full test matrix.
24- references/platform-boot-exact-alarms-oem.md — boot re-arm, exact-alarm degradation, background-isolate safety, Android manifest/Gradle, the OEM survival matrix.

28## Non-negotiable rules
29
301. **The local DB is the ONLY source of truth.** The OS pending-notification set is a disposable cache you reconcile against — never the store of record. Every reminder must be reconstructible from the DB alone after process death, reboot, Doze, or restore.
312. **Route EVERY scheduling change through one syncNotifications() reconcile entrypoint.** Never call gateway.schedule()/cancel() ad hoc from feature or UI code — that path cannot be made idempotent and desyncs the cache.
323. **Import flutter_local_notifications in exactly one file** — the FLN adapter. Everything else, including all tests, talks to the NotificationGateway port. A grep gate fails the build on any other import.
334. **Keep all scheduling math in pure, side-effect-free classes.** No plugin calls, no IO, no DateTime.now() inside them — inject a Clock from package:clock: Riverpod code reads it from clockProvider, the pure math takes it as a parameter (never DateTime.now(), never a bespoke ClockService). Purity is what makes off-device unit testing via FakeNotificationGateway possible.
345. **Store recurring schedules as wall-clock + recurrence rule, resolve to TZDateTime only at schedule time.** Never persist a recurring schedule as a UTC instant — it drifts an hour across every DST boundary. True one-off instants stay UTC epoch millis.
356. **Set tz.local at startup** (from flutter_timezone). The timezone package defaults to UTC — forget this and every zonedSchedule fires at the wrong local hour.

Why you can read it

Nothing in a skill executes. The client loads the text and the model follows it, so a skill can be audited the way a runbook is — by reading it.

What it costs in context

Skills are not billed by the call. They are paid for in context: every token the instructions occupy is a token your code, your diff and your conversation cannot use. Here is what this one takes and when it takes it.

≈250
always loaded

050k100k150k200k context window

8k tokens, estimated from the bundle at four bytes to the token, held for the rest of the session once it triggers. Heavy. Teams tend to install this one per project rather than globally, and load it only when the job comes up.

Servers bill, skills cost

A server charges by the month. A skill charges once per session, in context, and then keeps charging it for as long as the session lives.

Before and after

The same question, put to the same model twice: once as it comes, and once with these instructions loaded.

No worked example has been published for this skill yet.

The procedure it runs

The procedure has not been set out here step by step. It is in the body of its SKILL.md: the start of it is shown above, and the whole file comes with the install.

Prose, not code

These steps are written for a model to follow, not executed by a runtime. It can still be told to skip one, and it will say so when it does.

Servers it uses

None. This skill calls no MCP servers at all.

Everything it needs is in the instructions, so it works in a project with nothing connected — the model reads the file and changes how it works with what it can already reach.

Its SKILL.md does not declare which tools it asks the agent for, so what it touches is whatever the instructions themselves ask for — read them before you install it.

What it asks for
Writes filesnot declared
Network accessnot declared

This SKILL.md carries no allowed-tools line, so neither is declared. A skill grants no permissions of its own — it can only ask for tools your client already has.

What it will not do

Every skill is narrow, and the useful ones say where they stop. These are the jobs this one is the wrong tool for.

What this skill is not for has not been published here. Nothing is implied by that: it is a section the author has not filled in.

What is in the bundle

The download carries 8 of the 11 files in its source folder; the list here names 8 files, 36.2 kB on disk. Mostly text — the instructions the model reads — with 4 scripts in it that your client would run only if the instructions tell it to. The other 3 are not in the download — listed after these, with why.

  • SKILL.md15.4 kB
  • references/notification-gateway-port.md4.7 kB
  • references/platform-boot-exact-alarms-oem.md5.9 kB
  • references/scheduler-and-recurrence-rules.md5.9 kB
  • scripts/check-adhoc-schedule-calls.sh0.8 kB
  • scripts/check-manifest-permissions.sh1.0 kB
  • scripts/check-scheduler-purity.sh1.4 kB
  • scripts/check-single-fln-import.sh1.1 kB

Not in the download

Not carried is a type a skill download does not hold. Marked read: its SKILL.md or scripts name the file, so without it the skill works only in part. Take them from its source.

What is not in it

A skill installs nothing and depends on nothing: it is a folder your client reads. This one carries 4 scripts beside the text, so the download is 8 files — not the whole of its source: 3 files are left out, and the skill reads 3 of them. They are listed under the files, with why. The MIT licence covers the templates and examples as well as the instructions.

Install

Installing copies the bundle into your project. Nothing runs at install time — the files sit on disk until the model reads them.

# Local Notifications Scheduler · 8k tokens when loaded · macOS, Linux mkdir -p .claude/skills && t=$(mktemp -d) && curl -fsSL -o "$t/bundle.tar.gz" https://mcprush.com/api/skills/local-notifications-scheduler/bundle.tar.gz && tar -xzf "$t/bundle.tar.gz" -C "$t" && [ -d "$t/local-notifications-scheduler" ] && { [ ! -e .claude/skills/local-notifications-scheduler ] || { mv .claude/skills/local-notifications-scheduler "$t/.previous" && echo "Previous copy moved to $t/.previous"; }; } && mv "$t/local-notifications-scheduler" .claude/skills/ && echo "Installed .claude/skills/local-notifications-scheduler"

npx mcprush@latest skill add zakariaf/local-notifications-scheduler

Windows PowerShell says 'running scripts is disabled on this system'? Run Set-ExecutionPolicy -Scope CurrentUser RemoteSigned once, or type npx.cmd instead of npx (codex.cmd, gemini.cmd, grok.cmd likewise). PowerShell 7 needs neither. Writes to .claude/skills/local-notifications-scheduler/ in the current project. For every project instead, run mkdir -p ~/.claude/skills && t=$(mktemp -d) && curl -fsSL -o "$t/bundle.tar.gz" https://mcprush.com/api/skills/local-notifications-scheduler/bundle.tar.gz && tar -xzf "$t/bundle.tar.gz" -C "$t" && [ -d "$t/local-notifications-scheduler" ] && { [ ! -e ~/.claude/skills/local-notifications-scheduler ] || { mv ~/.claude/skills/local-notifications-scheduler "$t/.previous" && echo "Previous copy moved to $t/.previous"; }; } && mv "$t/local-notifications-scheduler" ~/.claude/skills/ && echo "Installed ~/.claude/skills/local-notifications-scheduler" (macOS, Linux) — or add --global to the npx line. The curl line replaces .claude/skills/local-notifications-scheduler/ only after the download succeeds, so files left there by another skill of the same name, or by an older release, do not mix in. A copy already there is moved aside, not deleted, and the line prints where. Not in this download: 3 files of its source, 3 of them read by its SKILL.md or scripts (the full list, and why). Take them from its source.

Which clients pick it up on their own

A skill is a folder of text. Most of these read a skills folder and pick it up without being told; the rest take the same folder another way — an upload in the app, a parameter on an API call — and then choose it by its description just the same.

Versions

Its author publishes no version number, so there is nothing here to pin to: what you install is the folder as it stands today. Instructions change more often than APIs do — a skill can be rewritten entirely without anything it depends on moving.

Pinning

Nothing to pin to: this skill carries no version number of its own. What you install is what the folder holds on the day you install it.
