From the project READMEXRPL Standards
Raw specification files for all 75 XRPL Standards (XLS-1 through XLS-102), organized by topic. Read the relevant file to get the full spec — field definitions, transaction formats, ledger objects, failure conditions, invariants, and RPC changes.
How to Use
The path depends on your environment. Find this skill's install directory and read the spec file directly:
Read <skill-dir>/references/<topic>/<file>.md
Common locations:
- claude.ai:
/mnt/skills/user/xrpl-standards/ - Claude Code (
npx skills add):.claude/skills/xrpl-standards/(relative to project root)
To auto-detect, search for the skill directory:
find /mnt/skills ~/.claude -name "INDEX.md" -path "*/xrpl-standards/references/*" 2>/dev/null | head -1 | sed 's|/references/INDEX.md||'
To list or fetch a spec not yet in refs:
bash <skill-dir>/scripts/list-xls.sh
bash <skill-dir>/scripts/fetch-xls.sh <number>
