Read the completed execplan `.agent/execplan-pending.md` 2. Locate ARCHITECTURE.md at the repo root 3. Analyze what was implemented in the execplan and identify architectural impacts: - New modules or bounded contexts - Changed data flows or boundaries - New integrations or dependencies - Updated directory structure - New cross-cutting concerns 4. Update only the affected sections of ARCHITECTURE.md 5. If diagrams exist, update Mermaid diagrams to reflect new components/flows 6. After all of your updates, stage any unstaged changes, then commit. ## Update Principles - Preserve existing structure and formatting - Add to existing sections rather than rewriting - Update Key Design Decisions with new decisions made during implementation - Move resolved items from Open Questions to appropriate sections - Keep the same level of detail as the existing doc ## If No ARCHITECTURE.md Exists Create one using the architecture-docs-creator skill template, populated with the current state post-implementation. --- > Converted and distributed by [TomeVault](https://tomevault.io/claim/grp06) — claim your Tome and manage your conversions.
