Rule llms-txt.summary-missing
Add a one-line summary at the top of /llms.txt
llms-txt.summary-missing is a check in Crawlmind's site audit that grades medium-impact issues of this kind. This page explains why the rule matters and the exact fix.
Why it matters
The llmstxt.org spec defines the summary as the first paragraph after the H1. Skipping it or filling it with corporate boilerplate ("we are a leading provider of solutions") forfeits the strongest signal an AI engine has for "what is this site about" in three lines or fewer.
The fix
Good summaries are concrete and one sentence long:
```markdown
# Crawlmind
> Crawlmind audits websites for AI visibility, grading them on llms.txt presence, schema markup, robots-txt posture, and direct citation tracking across ChatGPT, Perplexity and Gemini.
```
Avoid:
- Generic mission statements ("we believe in...")
- Multi-paragraph descriptions (the engine wants three lines or fewer)
- Marketing-style hyperbole ("leading", "innovative")
