        "content": "To make sure *Claude* ignores certain lines in your Markdown (`.md`) instruction files\u2014so those lines are treated like comments\u2014you can use various commenting styles. Markdown doesn\u2019t define its own official comment syntax, but many Markdown flavors, tools, and parsers will ignore specific constructs. Here are some reliable options:\n\n---\n\n## \u2705 Practical ways to add comments in Markdown\n\n1. **HTML comments**  \n   Wrap your comment between `<!--` and `-->`. This is the most common approach. Many renderers ignore anything inside, so Claude likely will too (if it doesn\u2019t try to include them).  \n   Example:  \n   ```md\n   <!-- This is a comment and should be ignored by Claude -->\n   ```\n\n2. **\u201cReference-style link\u201d hack**  \n   Use an unused link-label definition whose label is a fake reference and the comment text is placed in the title. The document won't show the comment, and many parsers (and tools) entirely drop it during rendering. This is handy if HTML comments still show up in processing or logs.\n\n   Some variants:\n   ```md\n   [//]: # (This is a comment)\n   [//]: # \"Another comment\"\n   [comment]: # (Also here)\n   ```\n\n3. **Jekyll/GitHub / other extended syntax**  \n   If your Markdown flavor supports extra/comment extensions, you might be able to do block-comments using `{::comment}` .. `{:/comment}`. These are less universal but sometimes supported.  \n   ```md\n   {::comment}\n   This is a block comment that might be stripped out\n   {:/comment}\n   ```\n\n---\n\n## \u26a0 Caveats / considerations\n\n- **Different Markdown parsers treat comments differently**:  \n  Some tools will leave HTML comments in generated HTML (though invisible in rendering). Others might strip out or preserve the text in some intermediate state. If Claude parses the `.md` file *before* rendering, it might see HTML comments unless your pipeline strips them. ([alvinalexander.com](https://alvinalexander.com/technology/markdown-comments-syntax-not-in-generated-output/?utm_source=openai))\n\n- **Line vs block comments**:  \n  HTML comments and the `{::comment}` style support multiple lines. The reference-style link trick usually works only one line per comment. If you want to hide multiple lines, you might need to repeat the one-line comment or wrap them in a block-style comment (if available). ([linuxhint.com](https://linuxhint.com/markdown-comment/?utm_source=openai))\n\n- **File format & tooling**:  \n  If Claude or OpenClaw have a custom frontend or preprocessor that strips comments or has its own parser, certain syntaxes might not work. You may want to test: write a small `.md` file with comment lines, run Claude/OpenClaw to see if those lines are indeed ignored.\n\n- **Avoid parsing/conflict issues**:  \n  Make sure the comment syntax you use doesn\u2019t accidentally get parsed as something else. For example, using link-labels might trigger warnings if the same label appears elsewhere. Also HTML comment syntax should avoid nested `--` patterns which some parsers reject. ([gist.github.com](https://gist.github.com/jcbrinfo/9288b7776b3c7717bd5fd62c48001c70?utm_source=openai))\n\n---\n\n## \ud83d\udd0d Recommendation for Claude/OpenClaw\n\nBecause I don\u2019t have an official doc for *Claude/OpenClaw\u2019s comment syntax*, here\u2019s a suggestion that balances compatibility and safety:\n\n- Use HTML comments `<!-- comment -->` for general notes or when you\u2019re not sure if the other syntaxes are supported.  \n- For lines you *really* want Claude to ignore, use the reference-style link hack `[//]: # (comment here)`.  \n- If you need multi-line comments and it seems your tool supports extended syntax, you can try the `{::comment} \u2026 {:/comment}` style.\n\nIf you want, I can look up whether *Claude/OpenClaw* has specific or custom comment syntax, based on their latest docs or code, to give you an authoritative recommendation. Do you want me to fetch that?"

        "content": "Here\u2019s a more concrete breakdown plus examples showing what that trick means:\n\n---\n\n## What it means\n\n- In Markdown, you can define a reference-style link using a label in square brackets followed by a colon and the URL or title.  \n- If you make a link-label that you *don\u2019t* use anywhere else in the document (\u201cunused\u201d), it basically does nothing visible.  \n- You put your \u201ccomment text\u201d into the *title* portion of that definition\u2014Markdown allows something like `[label]: link \"title\"`.  \n- Since the link is unused, and the title is hidden (not shown unless the link is used), it acts like a comment: the text is there but ignored during rendering.\n\n---\n\n## \ud83d\udd27 Example(s)\n\nHere are two variants:\n\n### Variant A: Using `//` style label\n\n```md\n[//]: # (This is a comment that lasts one line)\n```\n\n- `//` is the link-label (you can pick any label that you're not using).\n- `#` is often used as a fake URL, or anything that satisfies the syntax.\n- `(This is a comment \u2026)` is the title content. Often you\u2019ll see parentheses here.\n\n### Variant B: Using `\"title\"` style\n\n```md\n[unused]: http://example.com \"This comment is in the title and will be ignored\"\n```\n\n- `unused` is the fake label (never used elsewhere).\n- `http://example.com` is a dummy URL (could be anything syntactically allowed).\n- `\"This comment \u2026 ignored\"` is the title: the comment text.\n- Because the link-label `unused` is not referenced in the Markdown body, it doesn\u2019t show anything.\n\n---\n\n## \u2705 Why this works\n\n- Markdown parsers see link definitions but only render them when the label is used.  \n- If the label is unused, the definition is not printed or shown.  \n- Title text (inside `\"\"` or `()` depending on style) typically only shows up when rendering the link; unused means title is hidden.  \n- So you\u2019ve embedded comment text invisibly.\n\n---\n\nIf you like, I can test out a few examples with Claude to see which are ignored reliably, so you can pick the most robust one."
