This tool only validates and orchestrates. It trusts the caller-supplied tool summaries to describe each real operation's input and output types accurately; if a summary is wrong (a bug in the registry data), a workflow can validate green and still fail at execution, and this package cannot detect that mismatch. The memory estimate is a deterministic approximation (per-step weight multipliers against an assumed input size), not a precise measurement of real memory use. Workflows never store document bytes in a saved configuration; you select or upload your input files again when executing a saved workflow.

How to use this tool

  1. Pick the operation that should run first. Each operation lists the file types it accepts, so you can start a chain from a PDF or from images (for example, an images-to-PDF step).
  2. Add the remaining operations in order from the available tool list. The builder checks every connection live: a step that produces images can only feed a step that accepts images, and an invalid edge is explained before you ever press run.
  3. Review the memory estimate and any network or account requirements, and confirm that a terminal operation such as encrypt sits in the final position.
  4. Run the chain once — each completed step feeds its local output directly to the next step, so you upload once and download a single result.
