The body is lean and assumes Claude's competence: terse callout rules, an intent map table, and copy-paste commands with no padding about what a hardware wallet is or how USB works; detailed rationale is offloaded to references/business-logic.md.

Every command section gives fully executable invocations with real flags and values (e.g. `wallet-cli send ethereum-1 --to 0xDEF... --amount '0.5 ETH' --fee-per-byte 15 --rbf`), plus explicit required-flag lists, making it copy-paste ready.

Multi-step and risky flows are clearly sequenced with validation checkpoints: 'session first' behavior, device-contention rules, a receive-address mismatch validation loop ('do not share... run genuine-check before retrying'), swap quote -> execute -> status chain, and a Common errors table mapping each error to a fix.

SKILL.md is a concise overview with a clearly signaled one-level-deep reference to references/business-logic.md (which exists and is real), and the body appropriately keeps command surface inline while offloading rationale; navigation is explicit.

Lists many concrete commands in-line (account discover, receive, balances, operations, send, swap quote/execute/status, genuine-check, assets token / token-by-id), matching the anchor for multiple specific concrete actions.

Explicitly answers what it does ('USB-based CLI for Ledger wallet flows' plus enumerated commands) and when to use it ('Use for any wallet-cli command execution and for mapping informal requests to the right command'), satisfying both what and when.

It names command surface terms (send, swap, receive, balances) but lacks the natural informal phrasings a user would say (e.g. 'check my balance', 'send funds', 'verify my Ledger'), and the explicit trigger guidance reads as internal instruction to Claude rather than user-facing keywords.

Scoped to Ledger hardware-wallet CLI operations with a distinctive command surface (genuine-check, swap quote/execute/status), giving it a clear niche unlikely to conflict with generic wallet or crypto skills.
