To generate Codex project instructions, this Skill synthesizes your existing AGENTS.md and .github/copilot-instructions.md files. It outputs a structured Markdown description with sections that respect frontmatter conventions and preserves your repository's current documentation standards.

Yes, you can sync documentation updates by using this Skill to synthesize inputs from both AGENTS.md and copilot-instructions.md. It ensures consistency across your project docs by preserving existing conventions while producing unified instruction text for onboarding and governance.

The best way to update repository constraints is to provide your current AGENTS.md and copilot-instructions.md. This Skill synthesizes these inputs to generate tailored Codex project instructions, reflecting updated setup commands, architecture navigation, and quality checklists.

You do not need to build frontmatter from scratch, as this Skill respects and preserves existing frontmatter structure. It processes your AGENTS.md and copilot-instructions.md to produce output that maintains the original name and description conventions.

A key limitation is that the output depends entirely on the content within your AGENTS.md and copilot-instructions.md. While it handles diverse repositories, it strictly preserves existing conventions, meaning it will not invent new architectural standards or setup commands not present in those source files.

Yes, it works directly with .github/copilot-instructions.md by synthesizing that file alongside AGENTS.md. This combination allows the generator to produce comprehensive Codex project instructions suitable for standalone use or direct inclusion in your repository documentation.
