What it does
Activitykit is an agent skill from dpearson2699/swift-ios-skills. Implement, review, or improve Live Activities and Dynamic Island experiences in iOS apps using ActivityKit. Use when building real-time updating widgets for the Lock Screen and Dynamic Island — delivery tracking, sports scores, ride-sharing status, workout timers, media playback, or any time-sensitive information that updates in real time. Also use when working with ActivityKit, ActivityAttributes, Activity lifecycle (request/update/end), Dynamic Island layouts (compact/minimal/expanded), push-to-update Live…
Its SKILL.md is about 4.6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `evals/evals.json` and `references/activitykit-patterns.md`).
It sits in Mobile, covering iOS development and Health and fitness tracking. The repository describes itself as: Agent Skills for iOS 26+, Swift 6.3, SwiftUI, and modern Apple frameworks.
When your agent uses it
- Building real-time updating widgets for the Lock Screen and Dynamic Island — delivery tracking
- Ride-sharing status
- Any time-sensitive information that updates in real time
- Working with ActivityKit
Example prompts
- “/activitykit”
Workflow steps
2 steps, taken from the step headings in SKILL.md.
- Create a new Live Activity
- Review existing Live Activity code
What it can do on your machine
Read from SKILL.md and the folder at commit 8d90fd1. 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
No scripts in the folder and no shell commands in SKILL.md (its code samples are swift).
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
Activitykit loads about 4.6k tokens when it runs, and up to ~13k if it reads all its reference files. Until then it costs about 142 tokens; SKILL.md has 1,489 words of instructions outside code blocks.
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); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,489 words (~4,623 tokens).
“ActivityKit owns real-time, glanceable Live Activities displayed on the Lock Screen and Dynamic Island. Ordinary timeline widgets belong in widgetkit, and generic APNs setup belongs in push-notifications; ActivityKit owns the Live Activity lifecycle and payload contract. aps.content-state must decode into…”
