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 | $0.10359 | $0.10359 |
| Opus 5 | $0.05180 | $0.05180 |
| Sonnet 5 | $0.02072 | $0.02072 |
| Haiku 4.5 | $0.01036 | $0.01036 |
Grade A, and why
BitcoinAddressFinder 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 4d 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
BitcoinAddressFinder is a high-performance, open-source tool for scanning Bitcoin and altcoin private keys and checking whether the derived addresses have balances. It supports 100+ cryptocurrencies and uses both CPU (Java) and GPU (OpenCL) key generation strategies.

Build System
The project uses Maven (minimum 3.6.3). There is no Maven Wrapper in this repository —
mvnw / mvnw.cmd do not exist, so use an installed mvn. Commands below are written that way;
a wrapper could be added later, but until it is, ./mvnw ... fails outright.
Common Commands
# Compile only
mvn compile
# Run all tests
mvn test
# Build fat JAR with all dependencies
mvn package -P assembly
# Build without tests
mvn package -DskipTests
# Generate coverage report
mvn test jacoco:report
# Skip LMDB-specific tests (useful when LMDB native libs unavailable)
mvn test -Dnet.ladenthin.bitcoinaddressfinder.disableLMDBTest=true
JVM / Compiler Flags
Tests run with -Xmx2g (no eager -Xms — forks are short-lived, one fresh JVM per test class with reuseForks=false, so an eager initial heap only inflated the spawn-time footprint) and several --add-opens / --add-exports to allow LMDB and internal module access. These are configured in pom.xml (<argLine>) and .mvn/jvm.config.
Error Prone static analysis with NullAway is active at compile time:
- All code in
net.ladenthinpackages must carry proper@Nullable/@NonNullannotations. - Compilation will fail on potential null-pointer issues unless annotated.

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.

BitcoinAddressFinder CLAUDE.md is an instructions file published in the GitHub repository bernardladenthin/BitcoinAddressFinder (245 stars, last pushed 2d ago), licensed Apache-2.0. It adds 10,359 tokens to every session, about $0.0518 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 2026-08-30.
