3Every development task has a finite budget including setup, tests, and reporting.
4Before running tests, estimate duration from available timings and identify the changed
5behavior or directly affected consumer. If timing is unknown, state an estimate; do not

7or repository suites require the owner's explicit request, never a skill, PRD, review,
8or default command. Remove checks that neither prove the requested main function nor
9expose its defects. Repeat only after a relevant change or failure.
10Every new security check requires the owner's explicit approval for that specific check;
11remove auxiliary security, assertion, hash, or bookkeeping blockers of useful work.

18- Confirm the required shell from the shebang, callers, CI, and repository docs. Use Bash when the target is Bash; do not claim POSIX portability unless it is required and tested.
19- Read the complete target script, immediate callers, sourced libraries, config, and nearby tests. Reuse existing argument, logging, state, and error conventions.
