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.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Rogue Agent · line 165 Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.
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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00039 | $0.01099 |
| Opus 5.5 | $0.00016 | $0.00440 |
| Sonnet 5.5 | $0.00008 | $0.00220 |
| Haiku 4.5 | $0.00004 | $0.00110 |
Grade A, and why
analytics-setup 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.
How it starts
The opening of the file, as written. The whole thing — 190 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Analytics Setup Generator
Generate a protocol-based analytics infrastructure that makes it easy to swap providers without changing app code.
When This Skill Activates
Use this skill when the user:
- Asks to "add analytics" or "set up analytics"
- Mentions "TelemetryDeck", "Firebase Analytics", "Mixpanel"
- Wants to "track events" or "add telemetry"
- Asks about "privacy-friendly analytics"
- Wants to swap analytics providers
Key Feature: Swappable Providers
The generated code uses a protocol-based architecture:
// Your app uses the protocol
analytics.track(.buttonTapped("subscribe"))
// Swap providers by changing ONE line:
let analytics: AnalyticsService = TelemetryDeckAnalytics() // or FirebaseAnalytics()
Pre-Generation Checks
1. Project Context Detection
- Check for existing analytics implementations
- Look for TelemetryDeck/Firebase/Mixpanel in Package.swift or Podfile
- Identify source file locations
2. Conflict Detection
Search for existing analytics:
Glob: **/*Analytics*.swift, **/*Telemetry*.swift
Grep: "protocol.*Analytics" or "TelemetryDeck" or "Firebase"
If found, ask user:
- Extend existing analytics?
- Replace with new implementation?
- Add new provider to existing setup?
Configuration Questions
Ask user via AskUserQuestion:
-
Which provider(s)?
- TelemetryDeck (privacy-friendly, recommended)
- Firebase Analytics
- Mixpanel
- None (NoOp for now, add later)
-
What events to track?
- App lifecycle (launch, background, foreground)
- Screen views
- User actions (buttons, features used)
- Errors
- Custom events
-
User properties?
- App version
- Subscription status
- Custom properties
Generation Process
Step 1: Create Core Files
Always generate these files:
AnalyticsService.swift- Protocol (never changes)AnalyticsEvent.swift- Event definitions (app-specific)NoOpAnalytics.swift- For testing/privacy mode
Step 2: Create Selected Provider(s)

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.

analytics-setup is a skill published in the GitHub repository rshankras/claude-code-apple-skills (816 stars, last pushed 2mo ago), licensed MIT. It adds 39 tokens to every session and 1,099 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.
