DOM list trimming​

  • dom.listItemLimit / dom.listLimit / domListLimit (number 0–100, "all", or "none")
  • Env override: TESTRONAUT_DOM_LIST_LIMIT
  • Default: 3 items per list. "all" keeps everything but can massively increase tokens and may break flows.

Resource guard (list/table completeness)​

Ensures detected resources (documents/files/rows) are fully processed before reporting success.

  • Config block: 
    "resourceGuard": {
      "enabled": true,
      "hrefIncludes": ["/document/", "/file/", "/download", "/attachment/"],
      "dataTypes": ["document", "file", "item", "row"]
    }
  • Env overrides:
    • TESTRONAUT_RESOURCE_GUARD (true/false)
    • TESTRONAUT_RESOURCE_HREF_PATTERNS (comma-separated)
    • TESTRONAUT_RESOURCE_DATA_TYPES (comma-separated)

enabled defaults to true. Adjust patterns to fit your app. Set to false to disable.

Key env vars (summary)​

  • TESTRONAUT_DOM_LIST_LIMIT — cap list items (0-100, all, none)
  • TESTRONAUT_RESOURCE_GUARD — enable/disable resource guard
  • TESTRONAUT_RESOURCE_HREF_PATTERNS — comma list of href substrings
  • TESTRONAUT_RESOURCE_DATA_TYPES — comma list of data-type values
