Update Introduction

Refresh the introduction in your README.md from nova.config.json.

Summary

The update-introduction recipe rewrites the introduction of a README.md file so the project description stays in sync with nova.config.json. It reuses the exact builder the generate must-haves read-me command uses, so the spliced introduction is byte-identical to a freshly generated region.

The recipe only touches the marked region. Everything before the <!-- nova-region: introduction --> marker and everything after the <!-- nova-region-end: introduction --> marker is left byte-identical, so hand-written prose around the introduction is never disturbed.

Prerequisites

• An existing README.md — The recipe updates a file in the project root; it does not create one. Use generate must-haves read-me to create the initial file.
• The introduction region markers — The README.md must contain the <!-- nova-region: introduction --> and <!-- nova-region-end: introduction --> markers. A generate must-haves read-me file has them by default.
• A project description — project.description.long in nova.config.json so there is an introduction to render.

Behavior

The recipe follows an in-place splice so it can only ever rewrite the region it owns.

• Region gate — The introduction region markers must both be present and correctly ordered. If the markers are absent, misordered, or the README.md was not generated by Nova, the recipe warns that the region markers were not found and returns without writing.
• Region-only splice — Only the content between the markers is replaced. The markers and all content outside them are preserved exactly.
• Not applicable — When the current nova.config.json yields no introduction, the recipe warns and returns without touching the file.
• Idempotent — When the regenerated introduction already matches the file on disk, the recipe reports that the introduction is already up to date and makes no write.

Settings

Settings are configured in nova.config.json under the recipes.read-me key. The update-introduction recipe is controlled by a single enabled toggle:

{
  "recipes": {
    "read-me": {
      "update-introduction": {
        "enabled": true
      }
    }
  }
}

When the recipe is not enabled, it warns and returns without touching any files.
