Function lint_string 

pub fn lint_string(
    content: &str,
    options: &LintOptions,
) -> Result<LintReport, Error>

Lint one rule file’s markdown content (frontmatter + body).

Validates frontmatter against the embedded schema and applies semantic checks such as name vs filename stem and trigger: auto requiring paths or keywords.

Examples

use agent_rules_tool::{lint_string, LintOptions};

let content = "---\nname: my-rule\ntrigger: always\n---\n\n# My rule\n";
let report = lint_string(content, &LintOptions::default())?;
assert!(report.valid);
