Original prompt

Summary

This repository was previously under the NREL-Sienna GitHub organization and has now been moved to Sienna-Platform. All references to the old organization name must be updated throughout the codebase.

Changes Required

1. Replace all occurrences of NREL-Sienna with Sienna-Platform in all files (READMEs, docs, CI/CD workflows, config files, source comments).

2. Replace all occurrences of nrel-sienna.github.io with sienna-platform.github.io in all links and URLs.

3. Update any Slack invite links to direct to the core-sienna Slack workspace (slug: core-sienna).

4. Do NOT change package names, Julia module names, or unrelated content.

The following is the prior conversation context from the user's chat exploration (may be truncated):

User: I want you open PRs on all the repositories in the Platform-Sienna organization to handle the rename from NREL-Sienna and remove all references to NREL-Sienna and make the links work with Platform-Sienna.

The Slack invite links should direct to core-sienna instead

Assistant: I'm unable to access the Platform-Sienna organization or its repositories — it appears the organization either doesn't exist yet, is private, or your account (jd-laraI) doesn't have the necessary permissions for me to access it on your behalf.

Here are a few things to check:

1. Organization name: Does Platform-Sienna exist on GitHub? You can verify at https://github.com/Platform-Sienna.
2. Permissions: Does your account have access to the organization's repositories? I can only operate on repositories that your account can access.
3. Private org: If the organization is private, GitHub Copilot may need to be explicitly authorized for it.

Once I can confirm access, I'd be happy to open PRs across all the repositories to:

• Replace all references to NREL-Sienna → Platform-Sienna in links, docs, and config files
• Update Slack invite links to point to core-sienna instead of whatever they currently reference

Could you verify the organization name and your access level, or share a list of the specific repositories you'd like me to update?

User: I meant Sienna-Platform. That was a typo

Assistant: I found 30 repositories in the Sienna-Platform org. I can already see many have nrel-sienna.github.io in their homepage fields. I'll now open PRs on all of them simultaneously to:

• Replace NREL-Sienna → Sienna-Platform in all links, docs, and configs
• Update nrel-sienna.github.io → sienna-platform.github.io
• Update Slack invite links to point to core-sienna

Launching all PRs now...

Assistant: I've kicked off PR creation agents for all 30 repositories in the Sienna-Platform organization. Here's a summary of what's been requested for each repo:

Changes being made across all repos:

1. NREL-Sienna → Sienna-Platform — in READMEs, docs, source code comments, CI/CD workflows, and config files
2. nrel-sienna.github.io → sienna-platform.github.io — in all URLs and links
3. Slack invite links — updated to point to the core-sienna workspace

All 30 repositories targeted:
