What problem does it solve? Changing an already-approved artifact in a spec-driven development pipeline normally forces you to restart the entire workflow, even when the change only affects one or two downstream stages. This Skill edits the artifact in place, logs the revision, and propagates revalidation flags only to the stages genuinely impacted. ## Core Features & Use Cases - In-place artifact editing: Modifies PRD, TRD, implementation code, code review, QA report, security review, or SRE review documents without recreating them from scratch. - Scoped downstream propagation: Uses the fixed pipeline order (PRD → TRD → implementation → code review → QA → security → SRE) to determine exactly which later stages require revalidation, leaving unaffected approvals intact. - Validation-debt resolution: Marks "VALIDAR DEPOIS" pending items as validated while preserving their history, and records every change in a revision log with date, author, and rationale. - Use Case: A stakeholder changes an acceptance criterion in an approved PRD. The Skill edits the PRD, logs the amendment, and flags only the TRD, implementation, and QA stages for revalidation instead of rerunning the whole pipeline. ## Quick Start Ask the assistant to amend the approved TRD for a specific feature slug to change a design decision and flag the affected downstream stages for revalidation.
