# declareMissingPathParams

**Kind:** Function

**Source:** [`atloria-monorepo/libs/parser-core/src/openapi/path-parameters.ts`](https://github.com/sherkety/atloria/blob/main/atloria-monorepo/libs/parser-core/src/openapi/path-parameters.ts#L122)

Last resort: declare any path template expression the assembled spec still leaves undeclared.

Runs over the finished spec rather than inside a parser precisely because it must not depend
on which parser produced the operation — an OpenAPI file with a thin `paths` block, a
framework we add next year, or a cross-file pass that rewrote a path and forgot its
parameters all land here. Names are taken verbatim from the published path, because a
parameter whose name differs from the token by so much as a sigil leaves the operation just
as uncallable as it was.

Returns how many it had to invent, which is the number to watch: every one of them is a
parser that should have known better.
