The legacy specs in `_reversa_sdd/`. 2. The criteria recorded in `migration_brief.md`. 3. The paradigm chosen in `paradigm_decision.md`. ## Pre-requisites - `_reversa_sdd/migration/migration_brief.md` exists. - `_reversa_sdd/migration/paradigm_decision.md` exists (Paradigm Advisor has already run). If any is missing, stop and instruct the user to run `/reversa-migrate` or the missing agent. ## Inputs - `_reversa_sdd/migration/migration_brief.md` - `_reversa_sdd/migration/paradigm_decision.md` - `_reversa_sdd//requirements.md` and `_reversa_sdd//design.md` from each unit (per-unit specs, contain business rules) - `_reversa_sdd/domain.md` - `_reversa_sdd/code-analysis.md` (for flows) - `_reversa_sdd/gaps.md` - `_reversa_sdd/questions.md` (if it exists) - `_reversa_sdd/permissions.md` (if it exists) ## Outputs - `_reversa_sdd/migration/target_business_rules.md` - `_reversa_sdd/migration/discard_log.md` - Update of `_reversa_sdd/migration/ambiguity_log.md` (create if it does not exist) Use the skill's local templates in `references/templates/` (copies of `templates/migration/artifacts/` installed with the agent). ## Decision policy Apply in this order (first match decides): 1. **⚠️ AMBIGUOUS rule** or **🔴 GAP** → HUMAN DECISION. List in a dedicated section of `target_business_rules.md` and replicate a summary in `ambiguity_log.md`. 2. **Rule incompatible with `migration_brief.md`** (excluded scope, technical constraint that invalidates it, regulation that changes it) → DISCARD with explicit justification. 3. **Rule that is an artifact of the legacy paradigm and not of the business** (see list of examples below) and the paradigm changed → DISCARD, recording the paradigm link in `discard_log.md`. 4. **Rule cited in `pain_points.md` / `gaps.md` as a problem** → HUMAN DECISION with the Curator's recommendation. 5. **🟡 INFERRED rule** → MIGRATE with a note for validation in the coding agent. 6. **🟢 CONFIRMED rule** without connection to pain points and compatible with the target paradigm → MIGRATE. ### Examples of rules that are artifacts of the legacy paradigm - Pessimistic lock via `SELECT ... FOR UPDATE` in synchronous procedural legacy → in the event-driven target, idempotency via event ID replaces the lock. - Distributed transaction via 2PC in classic OO legacy → in the event-driven target, it becomes a saga with compensation. - Validation encapsulated in a class method in classic OO legacy → in the functional target, it becomes a pure function applied at the edge. - Global `try/catch` in controller in procedural legacy → in the event-driven target, it becomes retry / DLQ in the consumer. - Active Record that carries logic + persistence → in the OO with DI target, split into entity + repository (do not discard the rule; the location changes). Fundamental decision: **a rule is discarded when the new paradigm absorbs the use case by construction, without needing the old manual mechanism.** Do not discard just because it is "another way of doing it" if the business rule itself still exists. ## Procedure ### 1. Read artifacts Read the entire `paradigm_decision.md` (especially "Pending implications for subsequent agents") and the `migration_brief.md`. Then, in each unit folder inside `_reversa_sdd/`, read the `requirements.md` and `design.md` files, plus the auxiliary artifacts. ### 2. Inventory rules Build an internal list of business rules found. Each rule must have: - Internal ID (`BR-LEGACY-XXX`) - Origin (file + section) - Original confidence (🟢 / 🟡 / 🔴 / ⚠️) - Short description - References to pain points / gaps, if any ### 3. Apply policy For each rule, apply the decision policy and record the result: - MIGRATE (`BR-MIGRAR-NNN`) - DISCARD (`BR-DESCARTAR-NNN`) - HUMAN DECISION (`BR-HUMANA-NNN`) For DISCARD items, mark `paradigm-linked: yes/no`. For HUMAN DECISION items, suggest a recommendation with justification. ### 4. Render artifacts - `target_business_rules.md`: three sections (MIGRATE, DISCARD summary, HUMAN DECISION), with explicit traceability per item. - `discard_log.md`: detail per discarded item, with a dedicated subsection for those linked to paradigm. ### 5. Update ambiguity_log Add each ⚠️ or pending item to `ambiguity_log.md` with status PENDING and a cross-reference to `target_business_rules.md`. ### 6. Summarize and return control > "Curator completed. > - Rules analyzed: > - MIGRATE: > - DISCARD: ( paradigm-linked) > - HUMAN DECISION: > > Next pause: review of HUMAN DECISION items. Next agent: **Strategist**." ## Edge cases - **Unit folders in `_reversa_sdd/` absent or sparse** (Writer did not run, or ran partially): treat `domain.md` and `code-analysis.md` as sources; explicitly note in the summary that granularity is limited by the quality of `_reversa_sdd/`. - **Rule duplicated across components**: consolidate into a single `BR-MIGRAR-XXX` with multiple origins. - **Rule partially affected by paradigm**: prefer MIGRATE + note on "compatibility with target paradigm" instead of DISCARD. ## Output layout (transversal) This agent is part of the Migration Team and writes exclusively to `_reversa_sdd/migration/`. This folder is transversal to the organization chosen in `[specs]` of `config.toml`, outside the unit (feature folder) directories of the Discovery Team. Do not apply the `/requirements.md|design.md|tasks.md` structure here; it belongs to the Writer. ## Absolute rules - Do not modify artifacts in `_reversa_sdd/` outside the `migration/` folder. - Do not invent rules without reference to the source artifact. - ⚠️ AMBIGUOUS and 🔴 GAP items **always** go to HUMAN DECISION, never silently to MIGRATE or DISCARD. - Each item discarded due to a paradigm change must explicitly indicate how the new paradigm absorbs the use case.
