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 | $0.00839 | $0.00839 |
| Opus 5 | $0.00419 | $0.00419 |
| Sonnet 5 | $0.00168 | $0.00168 |
| Haiku 4.5 | $0.00084 | $0.00084 |
Grade A, and why
Confetti 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 7d 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.

Project Overview
Confetti is a Swift package providing beautiful confetti particle animations for SwiftUI applications. It supports iOS 18+ and macOS 15+ with a clean, testable architecture.
Development Commands
Use these Make commands for development:
make setup # Install Mint and dependencies
make build # Build the package
make test # Run tests
make lint # Run SwiftLint
make format # Format code with SwiftFormat
make ci # Run all CI checks (required before PRs)
make open # Open package in Xcode
make open-example # Open example project
Always run make ci before submitting pull requests to ensure all checks pass.
Architecture
The project follows a 3-layer modular architecture with strict encapsulation:
ConfettiUI (SwiftUI Views & Components)
↓ Uses public API only
ConfettiPlayback (Playback Control & Rendering)
↓ Exposes minimal interface via computed properties
ConfettiCore (Internal Domain Models & Physics) - Hidden from external access
Key Modules:
/Sources/ConfettiCore/- Internal module - Core physics engine, state machine, and domain models (not exposed publicly)/Sources/ConfettiPlayback/- Public API -ConfettiPlayerwith encapsulated interface; hidesConfettiSimulationinternals/Sources/ConfettiUI/- UI layer - SwiftUI views and components built on public API/Example/- Complete demo app for iOS/macOS/Tests/- Unit tests using Swift Testing framework
Encapsulation Strategy:
ConfettiPlayerexposes only:renderStates,currentTime,duration,state(all read-only computed properties)- Internal
ConfettiSimulationis private, preventing external state manipulation - SSoT maintained through version-based cache invalidation (~180x speedup)

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.

Confetti CLAUDE.md is an instructions file published in the GitHub repository Koshimizu-Takehito/Confetti (13 stars, last pushed 12d ago), licensed MIT. It adds 839 tokens to every session, about $0.0042 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 2026-09-04.
