+## Prompt
+
+User requested: Complete command-line interface for TaskFlow. Built with Typer for clean, typed commands. Record PHRs at every stage for audit trail and carefully plan execution using SpecifyPlus phases.
+
+Requirements included:
+- Basic Level: Add, Delete, Update, View, Mark Complete
+- Intermediate Level: Priorities, Tags, Search, Filter, Sort
+- Advanced Level: Recurring Tasks, Due Dates
+- Project structure planned for future monorepo
+
+## Response snapshot
+
+Created comprehensive CLI specification covering:
+
+**8 User Stories** (P1-P3 prioritized):
+1. Initialize Project and Register Workers (P1)
+2. Create and Manage Tasks (P1)
+3. Execute Task Workflow (P1)
+4. Create and Manage Subtasks (P2)
+5. View Audit Trail (P2)
+6. Search, Filter, Sort (P2)
+7. Due Dates and Scheduling (P3)
+8. Interactive Mode (P3)
+
+**35 Functional Requirements** covering:
+- Project & Initialization (FR-001 to FR-003)
+- Workers with Human-Agent Parity (FR-004 to FR-007)
+- Task CRUD (FR-008 to FR-012)
+- Task Organization (FR-013 to FR-016)
+- Task Hierarchy (FR-017 to FR-020)
+- Workflow & Status (FR-021 to FR-023)
+- Audit Trail (FR-024 to FR-027)
+- Search/Filter/Sort (FR-028 to FR-030)
+- Storage (FR-031 to FR-033)
+- Interactive Mode (FR-034 to FR-035)
+
+**10 Success Criteria** all measurable
+**11 Edge Cases** with expected behavior
+**4 Key Entities**: Project, Worker, Task, AuditLog
+
+## Outcome
+
+- Impact: Comprehensive CLI specification ready for planning phase
+- Tests: spec-architect validation PASSED (9.0/10)
+- Files: 2 created (spec.md, requirements checklist)
+- Next prompts: /sp.plan cli-core
+- Reflection: Formal verification identified 2 minor gaps (agent_type requirement, delegation edge case) - both fixed immediately
+
+## Evaluation notes (flywheel)
+
+- Failure modes observed: None critical - spec was comprehensive on first pass
+- Graders run and results (PASS/FAIL): spec-architect: PASS (READY verdict)
+- Prompt variant (if applicable): N/A
+- Next experiment (smallest change to try): Consider adding time budget constraints to spec template

+## Prompt
+
+Validate specification completeness and quality for: specs/001-cli-core/spec.md
+
+Tasks requested:
+1. Analyze spec against reasoning framework (testability, completeness, ambiguity, traceability)
+2. Generate quality checklist
+3. Identify issues with severity levels
+4. Apply formal verification (Alloy-style)
+5. Return structured validation report with verdict
+
+## Response snapshot
+
+**Validation Results (Score: 9.0/10, Verdict: READY)**
+
+### Testability Assessment (10/10)
+- All 8 user stories have falsifiable acceptance scenarios
+- Success criteria use quantifiable metrics
+- Edge cases define concrete error messages
+- All 35 functional requirements are verifiable
+
+### Completeness Check (10/10)
+- Constraints section with specific boundaries
+- Non-goals section (8 out-of-scope items)
+- 10 edge cases with expected behavior
+- Assumptions documented explicitly
+
+### Ambiguity Detection (9/10)
+- Worker ID format defined (@handle)
+- Status transitions explicitly enumerated
+- Priority levels and date formats specified
+- Minor gaps: file locking details, interactive mode scope
+
+### Formal Verification (PASSED)
+**Invariants Verified:**
+- Worker Existence: HOLDS
+- Parent-Child Acyclicity: HOLDS (FR-019)
+- Status Transition Validity: HOLDS (FR-021)
+- Audit Completeness: HOLDS (FR-024)
+
+**Counterexamples Found:**
+1. Agent worker without agent_type (FR-006 gap) - FIXED
+2. Delegation to non-existent worker not handled - FIXED
+
+### Issues Identified
+| Severity | Issue | Resolution |
+|----------|-------|------------|
+| MAJOR | agent_type not required for agents | Fixed FR-006 |
+| MAJOR | Delegation edge case missing | Added to edge cases |
+| MINOR | Evals-first structure | Deferred |
+| MINOR | Time budget not in constraints | Deferred |
+
+## Outcome
+
+- Impact: Spec validated as production-ready with 2 fixes applied
+- Tests: 5 quality dimensions assessed, all PASSED
+- Files: 1 created (requirements checklist)
+- Next prompts: /sp.plan 001-cli-core
+- Reflection: Formal verification caught real gaps that could cause issues in Phase III MCP integration
+
+## Evaluation notes (flywheel)
+
+- Failure modes observed: Agent type requirement oversight could break audit trail integrity
+- Graders run and results (PASS/FAIL): Testability: PASS, Completeness: PASS, Ambiguity: PASS, Traceability: PASS, Formal: PASS
+- Prompt variant (if applicable): spec-architect v3.0 with formal verification
+- Next experiment (smallest change to try): Add time budget constraints to spec template for future features

+## Prompt
+
+User requested:
+1. Record PHRs for the spec-architect agent invocation first
+2. Share an overview for your spec
+
+## Response snapshot
+
+**PHR Recorded**: 0002-spec-architect-validation.spec.prompt.md
+
+**Spec Overview Provided**:
+
+### Mission
+Prove Human-Agent Parity: CLI treats @claude-code and @sarah identically as first-class workers.
+
+### Features by Priority
+- P1: Project/Worker Setup, Task CRUD, Workflow Magic Loop
+- P2: Subtask Hierarchy, Audit Trail, Search & Filter
+- P3: Due Dates, Recurring Tasks, Interactive Mode
+
+### Data Model (4 Core Entities)
+- Project: Container for tasks
+- Worker: Human or AI agent (@handle format)
+- Task: Unit of work with status, progress, hierarchy
+- AuditLog: Immutable action record
+
+### Constitutional Compliance
+- Audit: FR-024 to FR-027
+- Agent Parity: FR-004 to FR-007
+- Recursive Tasks: FR-017 to FR-020
+- Spec-Driven: This spec itself
+- Phase Continuity: Pydantic → SQLModel
+
+### Demo Flow
+10-step demo showing init → register → assign → work → complete → audit
+
+## Outcome
+
+- Impact: Clear spec overview for stakeholder review
+- Tests: N/A
+- Files: 1 PHR created
+- Next prompts: User approval of spec, then /sp.plan
+- Reflection: Overview format with tables works well for quick comprehension
+
+## Evaluation notes (flywheel)
+
+- Failure modes observed: None
+- Graders run and results (PASS/FAIL): N/A
+- Prompt variant (if applicable): N/A
+- Next experiment (smallest change to try): Consider adding visual diagrams for data model
