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.

SkillSpector: 1 finding, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- high Privilege Escalation · line 43 Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.
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 | $0.00051 | $0.00539 |
| Opus 5 | $0.00026 | $0.00269 |
| Sonnet 5 | $0.00010 | $0.00108 |
| Haiku 4.5 | $0.00005 | $0.00054 |
Grade A, and why
bitcoin-libraries-bdk-jvm 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.
What it actually says
bdk-jvm / bdk-android
JVM bindings to Rust BDK.
Repos:
github.com/bitcoindevkit/bdk-jvm(JVM desktop).github.com/bitcoindevkit/bdk-android(Android).
Install
Gradle (Android):
implementation 'org.bitcoindevkit:bdk-android:1.0.0'
Gradle (JVM):
implementation 'org.bitcoindevkit:bdk-jvm:1.0.0'
Quick example (Kotlin)
import org.bitcoindevkit.*
val descriptor = Descriptor("wpkh(xprv.../84h/0h/0h/0/*)", Network.BITCOIN)
val change = Descriptor("wpkh(xprv.../84h/0h/0h/1/*)", Network.BITCOIN)
val wallet = Wallet(descriptor, change, Network.BITCOIN, "/path/to/db")
val esplora = EsploraClient("https://mempool.space/api", null, 5, 100, null)
wallet.fullScan(esplora, 5, 1)
val addr = wallet.revealNextAddress(KeychainKind.EXTERNAL)
println(addr.address.asString())
Bindings
- Same API as Rust BDK and bdkpython.
- UniFFI auto-generates bindings.
- Coverage: ~95% of Rust BDK API.
Use cases
- Android wallets — modern alternative to bitcoinj.
- JVM desktop apps.
- Server-side JVM Bitcoin services.
Compared
See bitcoinj/SKILL.md for comparison.
Common pitfalls
- Native
.sofiles per Android architecture; APK size grows. - UniFFI bindings sometimes lag Rust by a version.

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.
- 4d ago First seen · 73 lines · 51 tokens per session scan A 22a4d29c7203
bitcoin-libraries-bdk-jvm is a skill published in the GitHub repository claude-dev-suite/claude-dev-suite (31 stars, last pushed 2d ago), licensed MIT. It adds 51 tokens to every session and 539 once invoked, about $0.0003 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.
