bvandeusenandClaude Opus 5.5 4c150cbc2f docs(6209): test prose in the present tense — "used to", "previously", "before this" restated as the failure shape
Twenty-eight test files described the code they guard by what it did
before a fix. Each is now the property and the failure it prevents, in the
present tense: the backfill snapshot, the per-dial calibration query, the
rule scope, the lesson trigger filter, the subshell global, the trash owner
scope, the version readout fallback, and others. A docstring line that
narrated the backup suite's own history is removed.

"""Every create_* tool says what it is NOT for.
WHY THIS EXISTS
Scribe's record kinds are reached for interchangeably — a note written where
a task was owed, a rule written where a snippet belonged — and the moment of
choice is the only moment a correction is cheap. The tool docstring IS the
agent-facing contract (product guidance lives there and nowhere else), so a docstring that only documents parameters answers "how do I call
this" while leaving "should I be calling this at all" unasked.
The gap tends to be lopsided: `create_rule` and `start_planning` are where a
disambiguator gets written first, while `create_note` — far and away the
highest-volume surface — is where it matters most. Guidance that sits only in
the rarest tools misses the most common one.
WHAT THIS PINS, AND WHAT IT DOES NOT
It asserts STRUCTURE, never wording: each create surface must name at least
two sibling surfaces, so a caller who reached for the wrong one is told
where the right one is. Prose stays free to be rewritten — pinning phrasing
would make every improvement a test failure, and a test that punishes
editing is a test that gets deleted.
It cannot tell whether the guidance is any GOOD. It only catches the
regression that actually happens: a docstring rewritten down to its
parameters, with the "is this even the right tool" paragraph quietly gone.
