+
+# Generate rippled Release Notes
+
+This skill generates a draft release notes blog post for a new rippled version, then sorts the entries into the correct subsections.
+
+## Execution constraints
+
+- **Do NOT write scripts** to sort or process the file. Prefer the Edit tool for targeted changes. Use Write only when replacing large sections that are impractical to edit incrementally.
+- **Output progress**: Before each major step (generating raw release notes, reviewing file, processing amendments, sorting entries, reformatting, cleanup), output a brief status message so the user can see progress.
+
+## Step 1: Generate the raw release notes
+
+Run the Python script from the repo root. Pass through all arguments from `$ARGUMENTS`:
+
+```bash
+python3 tools/generate-release-notes.py $ARGUMENTS
+```
+
+If the user didn't provide `--from` or `--to`, ask them for the base and target refs (tags or branches).
+
+The script will:
+- Fetch the version string from `BuildInfo.cpp`
+- Fetch all commits between the two refs
+- Fetch PR details (title, link, labels, files, description) via GraphQL
+- Compare `features.macro` between refs to identify amendment changes
+- Auto-sort amendment entries into the Amendments section
+- Output all other entries as unsorted with full context
+
+## Step 2: Review the generated file
+
+Read the output file (path shown in script output). Note the **Full Changelog** structure:
+- **Amendments section**: Contains auto-sorted entries and an HTML comment listing which amendments to include or remove
+- **Empty subsections**: Features, Breaking Changes, Bug Fixes, Refactors, Documentation, Testing, CI/Build
+- **Unsorted entries**: After the **Bug Bounties and Responsible Disclosures** section is an unsorted list of entries with title, link, labels, files, and description for context
+
+## Step 3: Process amendments
+
+Handle Amendments first, before sorting other entries.
+
+**3a. Process the auto-sorted Amendments subsection:**
+The HTML comment contains three lists — follow them exactly:
+- **Include**: Keep these entries.
+- **Exclude**: Remove these entries.
+- Entries on **neither** list: Remove these entries.
+
+**3b. Scan unsorted entries for unreleased amendment work:**
+Search through ALL unsorted entries for titles, labels, descriptions, or files that reference amendments on the "Exclude" or "Other amendments not part of this release" lists. Remove entries that directly implement, enable, fix, or refactor these amendments. Keep entries that are general changes that merely reference the amendment as motivation — if the code change is useful on its own regardless of whether the amendment ships, keep it.
+
+**3c. If you disagree with any amendment decisions, make a note to the user but do NOT deviate from the rules.**
+
+## Step 4: Sort remaining unsorted entries into subsections
+
+Move each remaining unsorted entry into the appropriate subsection.
+
+Use these signals to categorize:
+
+**Files changed** (strongest signal):
+- Only `.github/`, `CMakeLists.txt`, `conan*`, CI config files → **CI/Build**
+- Only `src/test/`, `*_test.cpp` files → **Testing**
+- Only `*.md`, `docs/` files → **Documentation**
+
+**Labels** (strong signal):
+- `Bug` label → **Bug Fixes**
+
+**Title prefixes** (medium signal):
+- `fix:` → **Bug Fixes**
+- `feat:` → **Features**
+- `refactor:` → **Refactors**
+- `docs:` → **Documentation**
+- `test:` → **Testing**
+- `ci:`, `build:`, `chore:` → **CI/Build**
+
+**Description content** (when other signals are ambiguous):
+- Read the PR description to understand the change's purpose
+- PRs that change API behavior, remove features, or have "Breaking change" checked in their description → **Breaking Changes**
+
+Additional sorting guidance:
+- Watch for revert pairs: If a PR was committed and then reverted (or vice versa), check that the net effect is accounted for — don't include both.
+
+## Step 5: Reformat sorted entries
+
+After sorting, reformat each entry to match the release notes style.
+
+**Amendment entries** should follow this format:
+```markdown
+- **amendmentName**: Description of what the amendment does. ([#1234](https://github.com/XRPLF/rippled/pull/1234))
+```
+- Use more detail for amendment descriptions since they are the most important. Use present tense.
+- If there are multiple entries for the same amendment, merge into one, prioritizing the entry that describes the actual amendment.
+
+**Feature and Breaking Change entries** should follow this format:
+```markdown
+- Description of the change. ([#1234](https://github.com/XRPLF/rippled/pull/1234))
+```
+- Keep the description concise. Use past tense.
+
+**All other entries** should follow this format:
+```markdown
+- The PR title of the entry. ([#1234](https://github.com/XRPLF/rippled/pull/1234))
+```
+- Copy the PR title as-is. Only fix capitalization, remove conventional commit prefixes (fix:, feat:, ci:, refactor:, docs:, test:, chore:, build:), and adjust to past tense if needed. Do NOT rewrite, paraphrase, or summarize.
+
+## Step 6: Clean up
+
+- Add a short and generic description of changes to the existing `seo.description` frontmatter, e.g., "This version introduces new amendments and bug fixes." Do not create long lists of detailed changes.
+- Add a more detailed summary of the release to the existing "Introducing XRP Ledger Version X.Y.Z" section. Include amendment names (organized in a list if more than 2), featuress, and breaking changes. Limit this to 1 paragraph.
+- Do NOT delete the **Credits** or **Bug Bounties and Responsible Disclosures** sections
+- Remove empty subsections that have no entries
+- Remove all HTML comments (sorting instructions)
+- Do a final review of the release notes. If you see anything strange, or were forced to take unintuitive actions by these instructions, notify the user, but don't make changes.

-### Internationalization 
+### Localization / Translations
 
-This repo includes English (en) and Japanese (ja) locales. 
-
-This is done by setting up the internationalization (@l10n) folders, adding the `i18n` configuration to your `redocly.yaml` file, and adding the translated content in the respective language directory under the @l10n directory.
-
-To add support for a new language:
-
-1. Create a new subdirectory in the @l10n directory of the portal. For example, to add support for Spanish, create a new subdirectory "es-ES".
-
-2. Update the i18n configuration in your `redocly.yaml` file defining the display labels for the different languages you support.
-
-        l10n:
-          defaultLocale: en-US
-          locales:
-            - code: en-US
-              name: English
-            - code: ja
-              name: 日本語
-            - code: es-ES
-              name: Spanish
-
-3. Add the translated content in the respective language directory under the @l10n directory. 
-
-    The relative path from the language directory to the translated file must be the same as the relative path from the root of the portal to the file in the default language. For example, if you originally had a file with path `path/to/my/markdown.md`, the file translated to Spanish must be /`@l10n/es-ES/path/to/my/markdown.md`.
+The documentation in this repository is created in English first, then translated into other languages by community contributors. Currently, only the Japanese translations are live on the site; Spanish translation efforts are incomplete and not actively used.

-# Airgapped Wallet
-Airgapped describes a state where a device or a system becomes fully disconnected from other devices and systems. It is the maximum protection for a system against unwanted visitors/viruses, this allows any sensitive data like a private key to be stored without worry of it being compromised as long as reasonable security practices are being practiced.
-
-This airgapped XRP wallet allows users to sign a Payment transaction in a secure environment without the private key being exposed to a machine connected to the internet. The private key and seed is encrypted by password and stored securely.
-
-*Note*: You should not use this airgapped wallet in production, it should only be used for educational purposes only. 
-
-This code sample consists of 2 parts:
-
-- `airgapped-wallet.js` - This code should be stored in a standalone airgapped machine, it consist of features to generate a wallet, store a keypair securely, sign a transaction and share the signed transaction via QR code.
-- `relay-transaction.js` - This code could be stored in any online machine, no credentials is stored on this code other than a signed transaction which would be sent to an XRPL node for it to be validated on the ledger.
-
-Preferably, `airgapped-wallet.js` should be on a Linux machine while `relay-transaction.js` could be on any operating system.
-
-# Security Practices
-Strongly note that an airgapped system's security is not determined by its code alone but the security practices that are being followed by an operator.
-
-There are channels that can be maliciously used by outside parties to infiltrate an airgapped system and steal sensitive information.
-
-There are other ways malware could interact across airgapped networks, but they all involve an infected USB drive or a similar device introducing malware onto the airgapped machine. They could also involve a person physically accessing the computer, compromising it and installing malware or modifying its hardware.
-
-This is why it is also recommended to encrypt sensitive information being stored in an airgapped machine.
-
-The airgapped machine should have a few rules enforced to close any possible channels getting abused to leak information outside of the machine:
-
-### Wifi
-
-- Disable any wireless networking hardware on the airgapped machine. For example, if you have a desktop PC with a Wifi card, open the PC and remove the Wifi hardware. If you cannot do that, you could go to the system’s BIOS or UEFI firmware and disable the Wifi hardware.
-
-### BlueTooth
-
-- BlueTooth can be maliciously used by neighboring devices to steal data from an airgapped machine. It is recommended to remove or disable the BlueTooth hardware.  
-
-### USB
-
-- The USB port can be used to transfer files in and out of the airgapped machine and this may act as a threat to an airgapped machine if the USB drive is infected with a malware. So after installing & setting up this airgapped wallet, it is highly recommended to block off all USB ports by using a USB blocker and not use them.
-
-Do not reconnect the airgapped machine to a network, even when you need to transfer files! An effective airgapped machine should only serve 1 purpose, which is to store data and never open up a gateway for hackers to abuse and steal data.
-
-# Tutorial
-For testing purposes, you would need to have 2 machines and 1 phone in hand to scan the QR code.
-
-1. 1st machine would be airgapped, following the security practices written [here](#security-practices). It stores and manages an XRPL Wallet. 
-2. 2nd machine would be a normal computer connected to the internet. It relays a signed transaction blob to a rippled node.
-3. The phone would be used to scan a QR code, which contains a signed transaction blob. The phone would transmit it to the 2nd machine.
-
-The diagram below shows you the process of submitting a transaction to the XRPL:
-<p align="center">
-  <img src="https://user-images.githubusercontent.com/87929946/197970678-2a1b7f7e-d91e-424e-915e-5ba7d34689cc.png" width=75% height=75%>
-</p>
-
-# Setup
-- Machine 1 - An airgapped computer (during setup, it must be connected to the internet to download the files)
-- Machine 2 - A normal computer connected to the internet
-- Phone - A normal phone with a working camera to scan a QR
-
-## Machine 1 Setup
-Since this machine will be airgapped, it is best to use Linux as the Operating System.
-
-1. Clone all the files under the [`airgapped-wallet`](https://github.com/XRPLF/xrpl-dev-portal/tree/master/_code-samples/airgapped-wallet/js) directory
-
-2. Import all the modules required by running: `npm install`
-
-3. Airgap the machine by following the security practices written [here](#security-practices).
-
-4. Run `node airgapped-wallet.js`
-
-5. Scan the QR code and fund the account using the [testnet faucet](https://test.bithomp.com/faucet/) 
-
-6. Re-run the script and input '1' to generate a new transaction by following the instructions.
-
-7. Use your phone to scan the QR code, then to send the signed transaction to Machine 2 for submission
-
-## Phone Setup
-The phone requires a working camera that is able to scan a QR code and an internet connection for it to be able to transmit the signed transaction blob to Machine 2.
-
-Once you have signed a transaction in the airgapped machine, a QR code will be generated which will contain the signed transaction blob. Example:
-
-<img src="https://user-images.githubusercontent.com/87929946/196018292-f210a9f2-c5f8-412e-98c1-361a72286378.png" width=20% height=20%>
-
-Scan the QR code using the phone, copy it to the clipboard,  and transmit it to Machine 2, which will then be sending it to a rippled node.
-
-You can send a message to yourself using Discord, WhatsApp or even e-mail, then open up the message using Machine 2 to receive the signed transaction blob.
-
-## Machine 2 Setup
-This machine will be used to transmit a signed transaction blob from Machine 1, it would require internet access.
-
-1. Clone all the files under the [`airgapped-wallet`](https://github.com/XRPLF/xrpl-dev-portal/tree/master/_code-samples/airgapped-wallet/js) directory
-
-2. Import all the modules required by running `npm install`
-
-3. Run `relay-transaction.js` and copy-and-paste the received output of Machine 1 when prompted

-# Airgapped Wallet
-Airgapped describes a state where a device or a system becomes fully disconnected from other devices and systems. It is the maximum protection for a system against unwanted visitors/viruses, this allows any sensitive data like a private key to be stored without worry of it being compromised as long as reasonable security practices are being practiced.
-
-This airgapped XRP wallet allows users to sign a Payment transaction in a secure environment without the private key being exposed to a machine connected to the internet. The private key and seed is encrypted by password and stored securely.
-
-*Note*: You should not use this airgapped wallet in production, it should only be used for educational purposes only. 
-
-This code sample consists of 2 parts:
-
-- `airgapped-wallet.py` - This code should be stored in a standalone airgapped machine, it consist of features to generate a wallet, store a keypair securely, sign a transaction and share the signed transaction via QR code.
-- `relay-transaction.py` - This code could be stored in any online machine, no credentials is stored on this code other than a signed transaction which would be sent to an XRPL node for it to be validated on the ledger.
-
-Preferably, `airgapped-wallet.py` should be on a Linux machine while `relay-transaction.py` could be on any operating system.
-
-# Security Practices
-Strongly note that an airgapped system's security is not determined by its code alone but the security practices that are being followed by an operator.
-
-There are channels that can be maliciously used by outside parties to infiltrate an airgapped system and steal sensitive information.
-
-There are other ways malware could interact across airgapped networks, but they all involve an infected USB drive or a similar device introducing malware onto the airgapped machine. They could also involve a person physically accessing the computer, compromising it and installing malware or modifying its hardware.
-
-This is why it is also recommended to encrypt sensitive information being stored in an airgapped machine.
-
-The airgapped machine should have a few rules enforced to close any possible channels getting abused to leak information outside of the machine:
-### Wifi
-
-- Disable any wireless networking hardware on the airgapped machine. For example, if you have a desktop PC with a Wifi card, open the PC and remove the Wifi hardware. If you cannot do that, you could go to the system’s BIOS or UEFI firmware and disable the Wifi hardware.
-
-### BlueTooth
-
-- BlueTooth can be maliciously used by neighboring devices to steal data from an airgapped machine. It is recommended to remove or disable the BlueTooth hardware.  
-
-### USB
-
-- The USB port can be used to transfer files in and out of the airgapped machine and this may act as a threat to an airgapped machine if the USB drive is infected with a malware. So after installing & setting up this airgapped wallet, it is highly recommended to block off all USB ports by using a USB blocker and not use them.
-
-Do not reconnect the airgapped machine to a network, even when you need to transfer files! An effective airgapped machine should only serve 1 purpose, which is to store data and never open up a gateway for hackers to abuse and steal data.
-
-# Tutorial
-For testing purposes, you would need to have 2 machines and 1 phone in hand to scan the QR code.
-
-1. 1st machine would be airgapped, following the security practices written [here](#security-practices). It stores and manages an XRPL Wallet. 
-2. 2nd machine would be a normal computer connected to the internet. It relays a signed transaction blob to a rippled node.
-3. The phone would be used to scan a QR code, which contains a signed transaction blob. The phone would transmit it to the 2nd machine.
-
-The diagram below shows you the process of submitting a transaction to the XRPL:
-<p align="center">
-  <img src="https://user-images.githubusercontent.com/87929946/197970678-2a1b7f7e-d91e-424e-915e-5ba7d34689cc.png" width=75% height=75%>
-</p>
-
-# Setup
-- Machine 1 - An airgapped computer (during setup, it must be connected to the internet to download the files)
-- Machine 2 - A normal computer connected to the internet
-- Phone - A normal phone with a working camera to scan a QR
-
-## Machine 1 Setup
-Since this machine will be airgapped, it is best to use Linux as the Operating System.
-
-1. Install Python 3.8:
-
-**Linux Command Line**:
-```
-sudo apt-get update
-sudo apt-get install python3.8 python3-pip
-```
-**Website**: https://www.python.org/downloads/source/
-
-2. Clone all the files under the [`airgapped-wallet`](https://github.com/XRPLF/xrpl-dev-portal/tree/master/_code-samples/airgapped-wallet/py) directory
-
-3. Import all the modules required by running:
-```
-pip install -r requirements.txt
-```
-
-4. Airgap the machine by following the security practices written [here](#security-practices).
-
-5. Run `airgapped-wallet.py`
-
-6. Scan the QR code and fund the account using the [testnet faucet](https://test.bithomp.com/faucet/) 
-
-7. Re-run the script and input '1' to generate a new transaction by following the instructions.
-
-8. Use your phone to scan the QR code, then to send the signed transaction to Machine 2 for submission
-
-## Machine 2 Setup
-This machine will be used to transmit a signed transaction blob from Machine 1, it would require internet access.
-
-1. Install Python 3.8
-
-**Linux Command Line**:
-```
-sudo apt-get update
-sudo apt-get install python3.8 python3-pip
-```
-**Website**: https://www.python.org/downloads/source/
-
-2. Clone all the files under the [`airgapped-wallet`](https://github.com/XRPLF/xrpl-dev-portal/tree/master/_code-samples/airgapped-wallet/py) directory
-
-3. Import all the modules required by running:
-```
-pip install -r requirements.txt
-```
-
-4. Run `relay-transaction.py` with one argument, the signed transaction blob to submit.
-
-## Phone Setup
-The phone requires a working camera that is able to scan a QR code and an internet connection for it to be able to transmit the signed transaction blob to Machine 2.
-
-Once you have signed a transaction in the airgapped machine, a QR code will be generated which will contain the signed transaction blob. Example:
-
-<img src="https://user-images.githubusercontent.com/87929946/196018292-f210a9f2-c5f8-412e-98c1-361a72286378.png" width=20% height=20%>
-
-Scan the QR code using the phone and transmit it to Machine 2, which will then be sending it to a rippled node.
-
-You can send a message to yourself using Discord, WhatsApp or even e-mail, then open up the message using Machine 2 to receive the signed transaction blob.

+# Delete Account (JavaScript)
+
+JavaScript sample code showing how to delete an account from the XRP Ledger.
+
+## Setup
+
+```sh
+npm i
+```
+
+## Usage
+
+If you run the script by default, it gets an account from the faucet and outputs the details to the console. Example:
+
+```sh
+$ node delete-account.js 
+Got new account from faucet:
+    Address: rsuTU7xBF1u8jxKMw5UHvbKkLmvix7zQoe
+    Seed: sEdTpxrbDhe6M4YeHanSbCySFCZYrCk
+  
+Edit the .env file to add this seed, then wait until the account can be deleted.
+Account is too new to be deleted.
+    Account sequence + 255: 15226794
+    Validated ledger index: 15226538
+    (Sequence + 255 must be less than or equal to the ledger index)
+Estimate: 15 minutes until account can be deleted
+OK: Account owner count (0) is low enough.
+OK: Account balance (100000000 drops) is high enough.
+A total of 1 problem(s) prevent the account from being deleted.
+```
+
+Edit the `.env` file to add the seed of the account to delete. For example:
+
+```ini
+# Replace the seed with the seed of the account to delete.
+ACCOUNT_SEED=sEdTpxrbDhe6M4YeHanSbCySFCZYrCk
+# Change to secp256k1 if you generated the seed with that algorithm
+ACCOUNT_ALGORITHM=ed25519
+```
+
+Then run the script again:
+
+```sh
+node delete-account.js

+# Escrow (Go)
+
+This directory contains Go examples demonstrating how to create, finish, and cancel escrows on the XRP Ledger.
+
+## Setup
+
+All commands should be run from this `go/` directory.
+
+Install dependencies before running any examples:
+
+```sh
+go mod tidy
+```
+

+
+## Send Fungible Token Escrow
+
+```sh
+go run ./send-fungible-token-escrow
+```
+
+The script issues an MPT and Trust Line Token, setting up both to be escrowable. It then creates and finishes a conditional escrow with the MPT and a timed escrow with the Trust Line Token.
+
+```sh

+# Lending Protocol Examples (Go)
+
+This directory contains Go examples demonstrating how to create a loan broker, claw back first-loss capital, deposit and withdraw first-loss capital, create a loan, manage a loan, and repay a loan.
+
+## Setup
+
+All commands should be run from this `go/` directory.
+
+Install dependencies before running any examples:
+
+```sh
+go mod tidy
+```
+
+---
+
+## Create a Loan Broker
+
+```sh
+go run ./create-loan-broker
+```
+
+The script should output the LoanBrokerSet transaction, loan broker ID, and loan broker pseudo-account.
+
+```sh
+Loan broker/vault owner address: rLsTX2RjNTqwiwNpMn7mny3MyrXtmbhFQV
+Vault ID: A300D6F7D43E1B143683F1917EE6456B0C3E84F0F763D9A1366FCD22138A11E9
