FAQPage Schema

How do I convert plain text file paths into wikilinks in a markdown document?▼

To convert plain text file paths into wikilinks, this Skill proposes wikilink insertions by scanning markdown files for backtick-quoted paths and unquoted prose mentions, outputting unified diffs for human review before changes are applied.

Does automated markdown linking process files individually or scan an entire directory?▼

Automated markdown linking processes files individually, operating on a single markdown file at a time to ensure precise control over wikilink creation rather than scanning an entire documentation directory.

What is the best way to automate wikilink creation for existing documentation references?▼

The best way to automate wikilink creation is running this Skill on a specific markdown file, which uses deterministic regex processing to identify text mentions of file paths and proposes targeted wikilink insertions.

Can I use this markdown enhancement tool without granting filesystem access for local execution?▼

No, this markdown enhancement tool requires filesystem access and local execution to read markdown files and propose wikilink insertions based on text mentions of file paths.

How does wikilink file linking handle existing manually inserted links in markdown files?▼

Wikilink file linking uses deterministic regex processing to identify text mentions of file paths and outputs proposed insertions as unified diffs, allowing you to manually review and exclude existing links before applying changes.

When should I not use automated wikilink insertions for markdown documentation?▼

You should avoid automated wikilink insertions when your markdown files contain ambiguous path references or when you need immediate in-place file modifications, as this Skill requires local execution and outputs diffs for manual review.
