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 | $0.01284 | $0.01284 |
| Opus 5.5 | $0.00514 | $0.00514 |
| Sonnet 5.5 | $0.00257 | $0.00257 |
| Haiku 4.5 | $0.00128 | $0.00128 |
Grade A, and why
code-android-app 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 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.

Project Overview
Code/Flipcash is a mobile wallet app for instant, global, private payments using self-custodial blockchain (Solana/Kin) technology. The Android app is a multi-module Gradle project with 100+ modules.
Build Commands
# Build debug APK
./gradlew :apps:flipcash:app:assembleDebug
# Build release bundle
./gradlew :apps:flipcash:app:bundleRelease
# Run unit tests (all modules)
./gradlew test
# Run unit tests for a specific module
./gradlew :apps:flipcash:features:<feature>:test
# Run instrumented tests
./gradlew connectedAndroidTest
# Run tests via Fastlane (used in CI)
bundle exec fastlane android flipcash_tests
Requirements: Java 21 (Corretto), google-services.json in apps/flipcash/app/ (CI provisions it at apps/flipcash/app/src/; the Google Services plugin accepts either), API keys in local.properties (BUGSNAG_API_KEY, MIXPANEL_API_KEY, COINBASE_ONRAMP_API_KEY, GOOGLE_CLOUD_PROJECT_NUMBER). Keys resolve via tryReadProperty (local.properties → env var → empty), so a missing key won't fail the build but disables the dependent feature. See docs/architecture/10-build-and-run.md.

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.

code-android-app CLAUDE.md is an instructions file published in the GitHub repository code-payments/code-android-app (23 stars, last pushed today), licensed MIT. It adds 1,284 tokens to every session, about $0.0051 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.
