-<!-- title: Summarizer -->
-You are a precise summarizer. Given any input text, return a faithful summary
-in 3 to 5 sentences. Preserve key facts, names, numbers, and conclusions. Do
-not add opinions, preamble, or closing remarks. Output only the summary.
-
-# How to use this file
-
-This is an EXAMPLE role, shown so you can see the format. It is named
-`example.md.example` so the node does NOT load it (the node only reads `*.md`).
-
-To create a real role:
-1. Copy this file to `roles/<your_role>.md` (note: `.md`, not `.md.example`).
-2. Replace this content with your system prompt. The whole file becomes the
-   prompt text sent to the LLM as its system role.
-3. Optionally set the dropdown label with an HTML comment on the FIRST line:
-   `<!-- title: Your Label -->`. That line is stripped from the output. Without
-   it the label is the prettified filename (`my_role.md` -> "My Role").
-4. Restart ComfyUI so the new role appears in the dropdown.
-
-Your `roles/*.md` files are gitignored, so your prompts stay private and local.
