btc-terminology

btc-terminology is a skill for Claude Code from hiromaily/go-crypto-wallet. It costs 42 tokens per session (1,276 once invoked), scanned A, original, MIT.

A terminology guide for Bitcoin code and configuration. It explains that bech32m is an address encoding format, while taproot describes the kind of Bitcoin address or output.

In plain words
What is it for?
Use it when writing or reviewing Bitcoin address code, configuration files, environment variables, or Bitcoin Core commands.
Why use it?
It prevents code, configuration, and scripts from using these related but different terms interchangeably. That avoids confusing domain concepts with Bitcoin Core command parameters.

Token cost

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.

Security

Grade A, and why

btc-terminology 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 11d 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.

BTC Terminology Rules

🚨 CRITICAL: Bech32m vs Taproot

This is a common source of bugs. Do NOT confuse these terms:

Term What It Is Where Used
bech32m Encoding format (HOW address is serialized) Bitcoin Core RPC, shell scripts
taproot Address type (WHAT the address represents) Config files, domain model

Key Rule: bech32mtaproot — They are related but NOT interchangeable.

Quick Reference Table

Context Correct Term Example
Config YAML/TOML files taproot address_type: "taproot"
Environment variables taproot WALLET_ADDRESS_TYPE="taproot"
Bitcoin Core CLI/RPC bech32m bitcoin-cli getnewaddress "" bech32m
Shell scripts (receiver addresses) bech32m getnewaddress "" bech32m
Go domain code (internal/domain/address/) taproot AddrTypeTaproot
Go Bitcoin Core interface (internal/domain/bitcoin/) bech32m AddressTypeTaproot = "bech32m"

Common Mistakes

❌ WRONG

# Config file - DON'T use bech32m
address_type: "bech32m" # WRONG!
# Shell script - DON'T use taproot for Bitcoin Core RPC
bitcoin-cli getnewaddress "" taproot  # WRONG!

✅ CORRECT

# Config file - Use taproot
address_type: "taproot" # CORRECT!
# Shell script - Use bech32m for Bitcoin Core RPC
bitcoin-cli getnewaddress "" bech32m  # CORRECT!

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.
