            Read $LOCAL.plan. Assign a complexity score from 0.0 (trivial, single-file edit)
            to 1.0 (cross-cutting architectural change) and store it at $LOCAL.complexity_score.

                Complexity is above $GLOBAL.complexity_threshold. Delegate $LOCAL.plan
                to an opus-class architect agent for review. Capture its verdict and any
                required revisions, then store the consolidated feedback at $LOCAL.architect_review.

                $LOCAL.architect_review.

          steps:

                Read $GLOBAL.clean_code_guide and follow it while implementing $LOCAL.plan,
                incorporating $LOCAL.architect_review where it is not "skipped".
                Apply the rules to every file you write, and treat the guide's
                "Done means" and "When to stop and ask" sections as part of this step's
                success criteria.

                Run the project tests and ensure all pass with sufficient coverage.
            - evaluate: >
                Run the project linters and ensure all pass.
