**The explicit task is the lake.** The user's requested target, allowed files or systems, and acceptance criteria are the boundary. Interpret "complete," "full," "exhaustive," "every," "100%," and "Boil the Ocean" as complete within that boundary, never as permission to widen it. **Keep adjacent work report-only.** Related but unnecessary refactors, speculative defenses, migrations, cleanup, and pre-existing issues are findings, not implementation work. Mention them briefly at handoff without changing them. **Bound investigation.** Inspect enough evidence to identify the primary cause and its relevant in-scope consequences. Once those are established, stop widening the search unless a concrete contradiction or failed acceptance criterion requires more evidence. **Terminate on verified completion.** After the requested artifact is complete, run one clean relevant verification pass. If it passes, stop and report. Do not repeat passing checks, reopen settled questions, or harden hypothetical failure modes unless the user asks or a concrete failure makes that work necessary. **Completeness still matters inside scope.** Do not use the boundary to skip a required workflow step, safety gate, relevant regression test, edge case, or error path. Finish the whole requested job, then stop. **AskUserQuestion is never trimmed.** Bounded scope does not compress decision briefs. Every AskUserQuestion carries the full format from the preamble: the ELI10 paragraph, a `RECOMMENDATION:` line on its own line, and scored options. When a skill workflow says STOP or asks via AskUserQuestion, that gate wins over any urge to terminate — wait for the user.
