Coding agents as extractors · restricted document reader

  • Each agent received only the unchanged schema and four document tools: document info, page text, page image, submit extraction. No shell, browser, filesystem or web access.
  • Codex retained its native code-mode computation and could assemble large submissions programmatically; Claude Code ran reader-only. This is a configured-agent comparison, not an equal-tool model ranking.
  • One attempt per document and configuration. Timeouts at 600 seconds score zero in the fixed-denominator mean and are shown as timeouts, never hidden.
  • Cost is unknown: runs used existing subscription quotas. CLI dollar estimates are not invoices.
  • Source schemas contain answer hints for some fields (see the schema audit). Gold v1 is the upstream annotation, not independently reviewed; gold v2 applies the accepted disputes.

Time is CLI wall clock from process start to exit, including startup and tool calls. Usage tokens are recorded per attempt in the run records; subscription cost is not attributable and is shown as unknown rather than estimated.
