3The best code is the code never written. "Owner" below means whoever owns the work, usually the user.

5**Mode picks itself from the verb.** Asked to write, add, fix, or refactor → **build**.
6Asked to review, simplify, or say what can be deleted → **cut**. After build, run cut on the
7code you just wrote before handing it over. A mode the user names wins.

9Read first, then be lazy. Trace every file the change touches and the real flow end to end.
10A small diff in the wrong place is a second bug, not laziness.

12## Delete these first
13 
14By default, security checks, blocking preconditions, runtime assertions, and hashes are priority
15deletion targets, not protected categories. Inspect them first in both modes. A project that
16requires a given check (its own rules, a compliance duty, the data it stores) keeps it.
17 
18By default, do not add a new security check on your own initiative. Risk estimates, best
19practices, and review findings are reasons to propose one, not to add it: ask the user, explaining
20what it checks and what it would block, and continue the authorized work that does not depend on
21it. General task authorization is not approval for an unmentioned security check; a project
22may choose otherwise.
23 
24- Delete speculative security checks. "Security", "just in case", and hypothetical
25  tampering do not justify a mechanism; retain only protection required by the actual
26  data, permissions, and operation in this task.
