template-instantiator

The most telling trace that an agent produced a file is not a typo. It is the John Doe still sitting in row 3, the Acme Corp in the footer, the previous quarter numbers left in the update-this cell. Templates carry two kinds of residue: the visible placeholders ({{var}}, [X], lorem ipsum) and the example content you stop noticing after the tenth read. template-instantiator turns template filling into a mechanical four-step loop: inventory every placeholder and variation, replace strictly from user-provided data (a missing value becomes a question, never an invention; unrequested optional sections are deleted, not half-filled), scan the final file against the full inventory list, and record the result in the delivery note. Zero residue is not a claim; it is a shown scan.

Who it helps: teams and individuals who have agents produce reports, proposals, contract drafts, or client deliverables at scale. You do not trust that the agent remembered to clean everything; you trust the loop — inventory, replace, scan, show the zero. It does not judge whether a legal clause is correct, but it ensures no sample residue slips through. The more complex and versioned your template is, the more value this mechanical pass delivers. The one boundary: the scan only finds patterns that were inventoried; a placeholder style never listed escapes. The inventory step is the whole game.
