Structure
- Action.py — Implementation.
- README — Purpose, I/O, examples.
- requirements.txt — Pure‑Python dependencies (no binary installs).
Contract
- Inputs — Typed, minimal, documented.
- Outputs — Deterministic structure; document edge cases.
Workflow
- Define input/output and write
Action.py. - Pin dependencies in
requirements.txt. - Test with small Payloads via Execute.
- Reuse across Flows and as Agent tools.
warning: Dependencies — Only packages that do not require binary installs in the build image are supported.
