## About

# XRPL 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 /references//.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:
```bash
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
bash /scripts/list-xls.sh
bash /scripts/fetch-xls.sh 
```
