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.

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 | $0.00047 | $0.03023 |
| Opus 5 | $0.00023 | $0.01511 |
| Sonnet 5 | $0.00009 | $0.00605 |
| Haiku 4.5 | $0.00005 | $0.00302 |
Grade A, and why
streak-tracker 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 6d 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 — 343 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Streak Tracker Generator
Generate a production streak tracking system that records consecutive days of user activity, calculates current and longest streaks, handles timezone-aware day boundaries, supports streak freeze/protection passes, and schedules streak-at-risk local notifications.
When This Skill Activates
Use this skill when the user:
- Asks to "add streaks" or "daily streak" tracking
- Wants "streak tracking" or "consecutive days" counting
- Mentions "engagement streaks" or "habit tracking"
- Asks about "streak freeze" or "streak protection"
- Wants "streak-at-risk" notifications or reminders
- Mentions "login streak" or "activity streak"
Pre-Generation Checks
1. Project Context Detection
- Check Swift version (requires Swift 5.9+)
- Check deployment target (iOS 17+ / macOS 14+ for @Observable and SwiftData)
- Check for SwiftData availability and existing model container setup
- Identify source file locations
2. Conflict Detection
Search for existing streak or habit tracking:
Glob: **/*Streak*.swift, **/*Habit*.swift, **/*DailyTrack*.swift
Grep: "streak" or "consecutiveDays" or "habitTrack" or "dailyStreak"
If existing streak/habit system found:
- Ask if user wants to replace or extend it
- If extending, generate only the missing components
3. Platform Detection
Determine if generating for iOS (UNUserNotificationCenter) or macOS (UNUserNotificationCenter available on macOS 11+) or both.
Configuration Questions
Ask user via AskUserQuestion:
-
Streak type?
- Daily (consecutive calendar days) -- recommended
- Weekly (at least one activity per calendar week)
- Custom interval (every N hours/days)
-
Storage backend?
- SwiftData (recommended for iOS 17+ / macOS 14+)
- UserDefaults (lightweight, no model container needed)
-
Include streak freeze/protection?
- Yes — users get limited freeze passes to preserve streaks on missed days
- No — strict consecutive tracking only
What ships with it
1 file 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.

streak-tracker is a skill published in the GitHub repository rshankras/claude-code-apple-skills (713 stars, last pushed 1mo ago), licensed MIT. It adds 47 tokens to every session and 3,023 once invoked, about $0.0002 per session on Opus 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 2026-09-03.
