Enable a new GitHub Copilot model

This skill creates a PR to enable a new model in the enterprise-level Copilot settings.

Usage

Provide the full model name (e.g. "Anthropic Claude Opus 4.7", "OpenAI GPT-5.5", "Google Gemini 4 Pro").

Steps

1. Read the current state of docs/decisions/0002-enterprise-ai-controls.md.
2. Checkout a new branch from main named enable-<model-name-lowercased-with-hyphens> (e.g. enable-claude-opus-4.7, enable-gpt-5.5). The model vendor prefix (e.g. "Anthropic", "OpenAI", "Google") should be excluded from the branch name.
3. Make three changes to docs/decisions/0002-enterprise-ai-controls.md:
   • Update "Last Updated" date on line 4 to today's date in YYYY-MM-DD format.

• Add a new row to the ### Default models table for the new model. Insert it in the correct position among its vendor group (Anthropic, Google, OpenAI, xAI), maintaining alphabetical/version order within that group. Use Optional for the Status value. Pad with spaces to align the table columns.
• Add an amendments entry at the bottom of the ## Amendments section using this format:

  ### DD/MM/YY ([source](https://github.com/ministryofjustice/.github/pull/PLACEHOLDER))
  
  - Enable <Model Display Name>
  

  Use today's date in DD/MM/YY format. Use PLACEHOLDER for the PR number initially.

4. Commit the changes with the message :copilot: Enable <Model Display Name>.
5. Push the branch to origin.
6. Create a PR with:
   • Title: :copilot: Enable <Model Display Name>
   • Body:

     ## Proposed Changes
     
     - Enables <Model Display Name> model
     

   • Base: main
7. After the PR is created and you have the PR number, update the PLACEHOLDER in the amendments section with the actual PR number, commit with message Update PR number reference, and push again.

Example

For model name "Anthropic Claude Opus 4.7":

• Branch: enable-claude-opus-4.7
• PR Title: :copilot: Enable Claude Opus 4.7
• PR Body:

  ## Proposed Changes
  
  - Enables Claude Opus 4.7 model
  

• Table row: | Anthropic Claude Opus 4.7 | Optional |
• Amendment: ### 16/04/26 ([source](https://github.com/ministryofjustice/.github/pull/40))\n\n- Enable Claude Opus 4.7

Important Notes

• The model display name in the PR title, body, commit message, and amendments should not include the vendor prefix (e.g. use "Claude Opus 4.7" not "Anthropic Claude Opus 4.7"). The vendor prefix is only used in the models table row.
• The branch name uses the model name without the vendor prefix, lowercased, with spaces replaced by hyphens.
• Always check the current state of the file first to avoid duplicates and to find the correct insertion point.
