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 | $0.11402 | $0.11402 |
| Opus 5 | $0.05701 | $0.05701 |
| Sonnet 5 | $0.02280 | $0.02280 |
| Haiku 4.5 | $0.01140 | $0.01140 |
Grade A, and why
AppBootstrapAI CLAUDE.md 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 — 516 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md
Project Overview
AppBootstrapAI is a drop-in bundle of Claude Code skills and AI steering rules for bootstrapping new app projects. Covers Apple platforms (iOS, macOS, tvOS, watchOS, visionOS — Swift 6.4 concurrency, SwiftUI, Swift Testing, Foundation Models, Objective-C) and Android (Kotlin, Jetpack Compose, MVVM, Hilt, coroutines) in one bundle. Skills (deep-dive review agents) ship for both sides — 10 Apple, 7 Android — alongside the always-loaded steering rules.
This repo is not a Swift package. It is a collection of .claude/ assets intended to be copied (or referenced) into a target app repository so that Claude Code picks up consistent review, testing, and style guidance across projects.

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.
- 6d ago First seen · 516 lines · 11,402 tokens per session scan A ab94430aad50
AppBootstrapAI CLAUDE.md is an instructions file published in the GitHub repository kelvinkosbab/AppBootstrapAI (5 stars, last pushed 15d ago), licensed MIT. It adds 11,402 tokens to every session, about $0.0570 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 2026-08-31.
