Tools (6)
fitter_config_referenceReturn a condensed reference of the whole config format (connectors, parsers, model/field schema, placeholders, notifiers, references, limits) with working examples, so the model can author configs without external docs
Parameters not published.
fitter_inspect_urlFetch a URL and return a compact structure outline + candidate selectors/paths (gjson paths for JSON; repeated-element/list-row selectors for HTML) so the model authors a config first-try instead of guessing selectors and getting nulls. Detects client-rendered SPAs and can `render` them in a headless browser. Read-only — does not extract
Parameters not published.
fitter_runRun a Fitter config passed inline (JSON or YAML string) and return the extracted data as JSON. Accepts an optional `input` value available in the config via `{{{FromInput=.}}}` / `{{{FromInput=json.path}}}`
Parameters not published.
fitter_run_fileSame as `fitter_run` but reads the config from a local `.json`/`.yaml` file
Parameters not published.
fitter_run_urlSame as `fitter_run` but downloads the config from an HTTP(S) URL, e.g. a raw GitHub link
Parameters not published.
fitter_validate_configValidate a config without executing it (structure, `response_type`, connector data source, model). Useful while iterating on a config
Parameters not published.
