Validation Rules

The YAML validator reports these errors. All MUST be fixed before committing.

Error Cause Fix
name is required Top-level test.name missing Add name: "..."
version is required Top-level test.version missing Add version: "1.0.0"
steps is required No steps block Add at least one step
Step name is required A step has no name Every step needs a unique name
low_limit must be < high_limit Limits inverted Swap or correct the values
Undeclared variable 'x' {{x}} used but not in variables Add x to the variables block
Unknown step type 'foo' Typo in type: Use: delay, mock, prompt, sequence
duration is required for delay steps type: delay without duration: Add duration: <seconds>
max_iterations is required repeat: without max_iterations Add a safety cap
message is required for prompt type: prompt without prompt.message Add the message text

Two validation levels

Level Requires stack? What it catches
1 — Structural No Unknown fields, missing required fields, wrong types
2 — Semantic Yes Template variable resolution, limit ordering, step logic

Run py validate.py before every commit. Level 2 IS skipped gracefully when the stack is not running.
