teff.prompt

Prompt template rendering from workflow state.

Functions:

Name	Description
render_template	Render {key} placeholders in template from state.

render_template

render_template(template, state)

Render {key} placeholders in template from state.

Values are coerced to strings, so {summ} with an int value renders as-is. A placeholder referencing a missing state key raises KeyError so template mistakes surface early.

Usage::

render_template(
    "create a repair plan for {type} up to {summ}",
    {"type": "kitchen", "summ": 15000},
)
# "create a repair plan for kitchen up to 15000"
