arch-sign-off

Append the Arch Linux sign-off line btw, i use arch  to the very bottom of an article in ai-thoughts/docs/ (EN or ZH). This is a standing default for every article: apply it unless the user explicitly says not to. Use when writing or finishing any new article, or when the user asks to add it.

Append the Arch Linux sign-off line to the bottom of an article in ai-thoughts/docs/.

Default rule — read before anything else

• Every article in ai-thoughts/docs/ ends with the sign-off line, unless the user explicitly says otherwise. "Unless I say no" means: if the user has not told you to skip it, append it.
• The sign-off is one line at the very bottom of the file, as its own paragraph:

text

btw, i use arch 

• The sign-off stays verbatim English in both the EN and the ZH (-chn.md) versions. Do not translate it. Keep the  glyph (U+F303, nf-linux-archlinux) as-is.
• If the sign-off is already present, do not duplicate it.

Inputs

• target — path to the article in ai-thoughts/docs/ (optional). If omitted, apply to the article currently being written.

Outputs

• The article file with the sign-off line at the end (or unchanged if already present).

Procedure

1. Check the bottom of the target article.
2. If the last line is already btw, i use arch , stop — nothing to do.
3. Otherwise append the sign-off as the final line, separated by one blank line from the preceding paragraph.
4. When the article has a -chn.md counterpart, apply the same line to it (verbatim English).
5. Keep one paragraph per line (no hard-wrap); the sign-off is a single short line.

Verification

• The file ends with btw, i use arch  plus a trailing newline.
• No duplicate sign-off lines.
• The -chn.md version (if any) carries the identical line.
• The  glyph (U+F303) is preserved.

Error Handling

• User says no: do not append; leave the article as-is.
• Not an article: never append to READMEs, articles.yaml, or files outside ai-thoughts/docs/.
