Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

live-activity-generator scanned grade A with 1 finding 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 11d 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.

Live Activity Generator

Generate a complete ActivityKit Live Activity implementation with Dynamic Island layouts, Lock Screen presentation, activity lifecycle management, and push-to-update support.

When This Skill Activates

Use this skill when the user:

  • Asks to "add Live Activities" or "add a Live Activity"
  • Mentions "Dynamic Island" layouts
  • Wants real-time status updates on the Lock Screen
  • Asks about "ActivityKit" or "ActivityAttributes"
  • Mentions "push-to-update" for live activities
  • Wants to show ongoing progress (delivery tracking, sports scores, timers, workouts)

Pre-Generation Checks

1. Project Context Detection

  • Check for existing ActivityKit implementations
  • Check for an existing widget extension target
  • Verify deployment target is iOS 16.1+
  • Identify source file locations

2. Conflict Detection

Search for existing Live Activity code:

Glob: **/*Activity*.swift, **/*LiveActivity*.swift
Grep: "ActivityKit" or "ActivityAttributes" or "ActivityConfiguration"

If an existing widget extension is found:

  • Ask if the Live Activity should be added to the existing widget bundle
  • Check for existing WidgetBundle to extend

If Live Activity code already exists:

  • Ask user whether to replace or extend

3. Required Capabilities

Live Activities require:

  • iOS 16.1+ deployment target
  • NSSupportsLiveActivities set to YES in Info.plist
  • A widget extension target (can share with existing WidgetKit widgets)
  • For push updates: NSSupportsLiveActivitiesFrequentUpdates (optional, iOS 16.2+)

Configuration Questions

Ask user via AskUserQuestion:

  1. What is the Live Activity for? (freeform)

    • Examples: delivery tracking, sports score, workout timer, ride-sharing, food order
    • This determines the attribute fields and content state
  2. What data should appear on the Lock Screen? (freeform)

    • Static data (set at start, does not change): e.g., restaurant name, order number
    • Dynamic data (updated over time): e.g., ETA, driver location, score

Changes

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.
