Document Scope

Just Headlines uses Resend as an email delivery provider for transactional email, SMTP relay, and related email-sending infrastructure.

This document defines the repeatable process for updating the Just Headlines Resend documentation context repository. The purpose of this task is to keep a focused copy of selected official Resend documentation and source material available inside the Just Headlines development environment so human developers, Codex sessions, AI agents, and future MCP/RAG tooling can read the relevant Resend API, SMTP, Node, Python, React, JavaScript, HTML email, OpenAPI, examples, and AI-tooling reference material locally without repeatedly relying on external website lookups or pasted documentation links.

This document is written for both human operators and AI agents. It explains what the local context repository is, why it exists, which official Resend sources are copied into the context repository, and what PowerShell block should be run whenever the Resend documentation context needs to be refreshed.

1. Purpose

The Resend documentation context repository exists so that Just Headlines has a local and GitLab-hosted copy of selected official Resend reference material needed for email delivery, SMTP relay, transactional email, API, Node, Python, React, JavaScript, HTML email, OpenAPI, and AI-agent-related integration work.

Unlike a context repository that mirrors one selected folder from one upstream Git repository, the Resend context repository is assembled from multiple official Resend sources. A normal git pull inside C:\dev\ctx-resend only updates the local copy from the Just Headlines GitLab context repository. It does not refresh the context repository from Resend's official sources.

The Resend update process does the following:

  1. Downloads the current Resend LLM documentation files.
  2. Pulls the latest selected files from the official Resend OpenAPI repository.
  3. Pulls the latest selected files from the official Resend Node SDK repository.
  4. Pulls the latest selected files from the official Resend Python SDK repository.
  5. Pulls the latest selected files from the official React Email repository.
  6. Pulls the latest selected files from official Resend example repositories.
  7. Pulls the latest selected files from official Resend AI-tooling repositories.

The main Resend developer documentation URL is:

https://resend.com/docs

2. Operational Use

Run this task whenever the Resend documentation context should be refreshed from official Resend sources.

This may be done manually during active email, SMTP, transactional email, notification, API, template, React Email, or AI-agent development, especially before asking Codex or another AI coding agent to rely on Resend implementation details.

After this task runs successfully, the local folder at C:\dev\ctx-resend should contain the latest selected Resend reference content, and the GitLab repository should contain a committed copy of that same refreshed context.

4. What This Script Does

This script performs the following task sequence:

  1. Changes the working directory to C:\dev.
  2. Removes the temporary Resend source checkout folder if it already exists.
  3. Creates the expected local context repository folders.
  4. Downloads the current Resend LLM documentation files.
  5. Clones each selected official Resend source repository.
  6. Copies selected files and folders from each source repository into the local context repository.
  7. Captures each upstream commit hash used for the refresh.
  8. Ensures the local context folder is a Git repository.
  9. Ensures the GitLab SSH remote is set correctly.
  10. Stages the refreshed Resend context content.
  11. Creates a verbose Git commit only if the context content changed.
  12. Pushes the update to GitLab.
  13. Deletes the temporary Resend source checkout folder.
  14. Shows the final Git status.

5. PowerShell Refresh Script

Refreshes the local GitLab context copy of selected official Resend documentation, SDK, example, React Email, OpenAPI, and AI tooling reference material.

Changed behavior:
- Downloads the latest Resend LLM documentation files.
- Replaces selected Resend OpenAPI reference files with the latest upstream copy.
- Replaces selected Resend Node SDK reference files with the latest upstream copy.
- Replaces selected Resend Python SDK reference files with the latest upstream copy.
- Replaces selected React Email reference files with the latest upstream copy.
- Replaces selected official Resend example files for Node, Vercel/Next, Cloudflare Workers, and related JavaScript usage.
- Replaces selected Resend MCP and Resend skills reference files for AI tooling context.

$SourceList

Operational context:
- Maintains an updated local and GitLab-hosted documentation context for Resend.
- Supports transactional email, SMTP relay, API, Node, Python, React, HTML email, JavaScript, and AI-agent development reference.
- Supports local review, Codex access, future documentation indexing, and future MCP/RAG workflows.
- Avoids depending on a single upstream Git pull because Resend context material is assembled from multiple official sources.

Validation performed:
- Downloaded the current Resend LLM documentation files.
- Pulled selected files and folders from official Resend GitHub repositories.
- Staged only the resulting context-repository changes.
"@

    git commit -m "Update Resend documentation context" -m "$CommitBody"
    git push origin main
}

cd C:\dev
Remove-Item -Recurse -Force $TempRoot -ErrorAction SilentlyContinue

cd $LocalRepo
git status

6. Expected Result

If the official Resend context material changed, the script should create and push a new commit with this subject:

Update Resend documentation context

If the official Resend context material did not change, the script should print:

No Resend documentation context changes to commit.

In either case, the final git status should show the current state of the local context repository.

7. AI Agent Instructions

When using this repository for email, SMTP relay, transactional email, notification, API, Node, Python, React, JavaScript, HTML email, OpenAPI, template, or Resend AI-tooling development, AI agents should treat C:\dev\ctx-resend as the local Resend documentation and source-material context.

AI agents should use the local context repository as the first reference source for Resend-related development work. The Resend developer website may still be used when the local context appears incomplete, stale, or insufficient for a specific implementation question.

Do not assume that a normal git pull inside C:\dev\ctx-resend refreshes the repository from Resend's official sources. It only refreshes the local copy from the Just Headlines GitLab context repository. To update from official Resend sources, run the PowerShell refresh script in this document.

8. Human Operator Notes

This script is safe to run repeatedly. It replaces the stored Resend context content with a fresh copy of the selected official source material.

The script does not store SSH keys, passphrases, tokens, Resend API keys, Resend SMTP credentials, Just Headlines secrets, or application configuration secrets. Git authentication is handled by the existing local SSH configuration on the operator's computer.

If GitLab blocks a push because the branch is protected, check the GitLab branch protection settings for the ctx-resend repository and confirm that normal pushes to main are permitted for the account performing this task.

9. Validation Checklist

After running the script, confirm the following:

  1. C:\dev\ctx-resend\docs\llms.txt exists.
  2. C:\dev\ctx-resend\docs\llms-full.txt exists.
  3. C:\dev\ctx-resend\openapi exists.
  4. C:\dev\ctx-resend\node exists.
  5. C:\dev\ctx-resend\python exists.
  6. C:\dev\ctx-resend\react-email exists.
  7. C:\dev\ctx-resend\examples exists.
  8. C:\dev\ctx-resend\ai exists.
  9. The local context repository contains selected Resend documentation, OpenAPI, SDK, example, React Email, and AI-tooling reference material.
  10. git status does not show unexpected staged changes.
  11. If changes were found, a commit was created.
  12. If a commit was created, it was pushed to git@gitlab-sudostac:sudostac/ctx-resend.git.
  13. The temporary folder C:\dev\_resend-source was removed.

10. Related Repositories

This document concerns the Resend documentation context repository only:

C:\dev\ctx-resend

It does not define the Just Headlines email, SMTP, transactional email, notification, React Email, or template implementation itself. The implementation belongs in the applicable Just Headlines application repository.
