Pull request overview

Adds YAML-based domain allowlisting via a new repeatable CLI flag --ruleset-file, enabling users to maintain allowlists as structured files while continuing to support existing --allow-domains / --allow-domains-file inputs.

Changes:

  • Introduces src/rules.ts to load/validate a version: 1 YAML ruleset format and merge rules into allowed domain strings.
  • Adds Jest coverage for ruleset parsing, validation errors, expansion, and merging (src/rules.test.ts).
  • Adds --ruleset-file <path> (repeatable) to the CLI and merges ruleset-derived domains into the allowlist (src/cli.ts).

Reviewed changes

Copilot reviewed 3 out of 3 changed files in this pull request and generated 2 comments.

File Description
src/rules.ts Implements YAML ruleset loading/validation and merging into allowlisted domains.
src/rules.test.ts Adds unit tests for ruleset parsing/validation and merge behavior.
src/cli.ts Adds --ruleset-file option and merges loaded ruleset domains into allowedDomains.

src/cli.ts:1167

  • loadAndMergeDomains() already returns a de-duplicated list, but the CLI still de-duplicates allowedDomains again immediately after. Consider de-duplicating in only one place (either inside loadAndMergeDomains or in the CLI) to avoid redundant work and keep responsibilities clearer.
    if (options.rulesetFile && Array.isArray(options.rulesetFile) && options.rulesetFile.length > 0) {
      try {
        allowedDomains = loadAndMergeDomains(options.rulesetFile, allowedDomains);
      } catch (error) {
        logger.error(`Failed to load ruleset file: ${error instanceof Error ? error.message : error}`);
        process.exit(1);
      }
    }

    // Log when no domains are specified (all network access will be blocked)
    if (allowedDomains.length === 0) {
      logger.debug('No allowed domains specified - all network access will be blocked');
    }

    // Remove duplicates (in case domains appear in both sources)
    allowedDomains = [...new Set(allowedDomains)];

/**
* Expands a single rule into domain strings suitable for the allowedDomains list.
*
* When subdomains is true (default), the domain is returned as-is because the
* existing domain normalization in squid-config.ts and domain-patterns.ts
* automatically adds subdomain matching (both "example.com" and ".example.com").
*
* When subdomains is false, the domain is prefixed with "exact:" to signal
* exact-match-only behavior. However, since the current squid config always
* adds subdomain matching, we return just the bare domain. The subdomain
* field is reserved for future granular control.
*
* @param rule - A single domain rule
