# Specification Analysis Report: MCP SSO Checklist Server **Feature**: `001-mcp-sso-checklist` **Analysis Date**: 2025-12-11 (Updated) **Artifacts Analyzed**: - `specs/001-mcp-sso-checklist/spec.md` - `specs/001-mcp-sso-checklist/design.md` - `specs/001-mcp-sso-checklist/tasks.md` - `memory/ground-rules.md` - `docs/architecture.md` - `docs/standards.md` --- ## Executive Summary The cross-artifact analysis reveals a **well-aligned specification set** with strong consistency across spec, design, and tasks. The artifacts demonstrate good traceability from requirements to implementation tasks. **Key Findings**: - **0 CRITICAL issues** - No ground-rules violations or blocking gaps - **2 HIGH issues** - Minor coverage gaps for non-functional requirements - **3 MEDIUM issues** - Terminology drift and underspecification - **2 LOW issues** - Minor redundancy in documentation **Recommendation**: Proceed with `/rainbow.implement`. Address HIGH issues during implementation. --- ## Findings Table | ID | Category | Severity | Location(s) | Summary | Recommendation | |----|----------|----------|-------------|---------|----------------| | C1 | Coverage | HIGH | spec.md:FR-006b, tasks.md | SSE streaming support (FR-006b) has no explicit task | Add SSE validation to T012 (MCP Server Core) or create dedicated task | | C2 | Coverage | HIGH | spec.md:SC-003, tasks.md | 8-hour session test (SC-003) mentioned in design but no explicit task | Add task for mocked-time integration test in Phase 5 | | A1 | Ambiguity | MEDIUM | spec.md:L203-204 | SC-001 "30 seconds" excludes browser/Azure time but metric is hard to isolate | Clarify measurement approach in quickstart.md | | T1 | Terminology | MEDIUM | spec.md vs tasks.md | Tool names vary: "get-checklist" (spec L194) vs "get_checklist" (tasks) | Standardize on snake_case per MCP tool conventions in standards.md | | U1 | Underspecification | MEDIUM | spec.md:FR-016 | "Format consumable by AI assistants" lacks concrete definition | Defined in contracts/mcp-tools.json - cross-reference in spec | | D1 | Duplication | LOW | spec.md:L145-146, L39-40 | FR-001 duplicates acceptance scenario US1.1 (browser window for auth) | Keep FR-001 as normative; scenarios as validation | | D2 | Duplication | LOW | architecture.md:§2.3.4, spec.md:SC-003 | AV-001 (8-hour session) duplicates SC-003 | Cross-reference, don't duplicate | --- ## Coverage Summary Table ### Functional Requirements Coverage | Requirement | Has Task? | Task ID(s) | Notes | |-------------|-----------|------------|-------| | FR-001: Browser auth window | YES | T017, T021 | BrowserAuth + server startup | | FR-002: OAuth 2.0 PKCE | YES | T017 | Browser Auth implementation | | FR-003: Session state | YES | T018, T019 | Auth Manager + Middleware | | FR-004: Token persistence + silent re-auth | YES | T016, T021 | TokenStore + startup integration | | FR-005: Token refresh (<5 min) | YES | T018 | Auth Manager handles refresh | | FR-006: MCP specification | YES | T012 | Server Core with FastMCP | | FR-006a: HTTP Streamable transport | YES | T012 | Explicit in task description | | FR-006b: SSE support | PARTIAL | T012 | Implicit in HTTP Streamable, no explicit test | | FR-007: get_checklist tool | YES | T032, T034 | Tool implementation + registration | | FR-008: list_checklists tool | YES | T040, T041 | Tool implementation + registration | | FR-009: Read from markdown files | YES | T028, T029, T030 | Parser + Discovery + Service | | FR-010: Dynamic discovery | YES | T029 | File Discovery without caching | | FR-011: JSON config for VSCode | YES | T043 | Configuration example | | FR-012: GitHub Copilot compatible | YES | T043 | VSCode MCP config | | FR-013: Claude Code compatible | YES | T044 | Claude config example | | FR-014: Clear config errors | YES | T046 | Startup validation | | FR-015: Multiple checklist types | YES | T006 | Sample checklist files | | FR-016: AI-consumable format | YES | T032, T040 | Defined in contracts/mcp-tools.json | | FR-017: Checklist not found error | YES | T035 | Error handling task | | FR-018: YAML frontmatter parsing | YES | T028 | Frontmatter Parser | ### Success Criteria Coverage | Criterion | Has Task? | Task ID(s) | Notes | |-----------|-----------|------------|-------| | SC-001: Auth <30s | PARTIAL | T018 | No explicit timing test | | SC-002: Retrieval <2s | PARTIAL | T027 | Integration test, no timing assertion | | SC-003: 8-hour session | NO | - | Mentioned in design.md but no task | | SC-004: 5-min setup | YES | T045, T051 | Quickstart + validation | | SC-005: List all checklists | YES | T038 | Integration test | | SC-006: Actionable errors | YES | T023, T035 | Error handling tasks | | SC-007: Server start <5s | PARTIAL | T012 | No explicit timing test | ### User Stories Coverage | Story | Tasks Count | Test Tasks | Implementation Tasks | |-------|-------------|------------|---------------------| | US1 (P1) - Auth | 11 | 3 (T013-T015) | 8 (T016-T023) | | US2 (P2) - Get Checklist | 13 | 4 (T024-T027) | 9 (T028-T036) | | US3 (P3) - List Checklists | 6 | 2 (T037-T038) | 4 (T039-T042) | | US4 (P4) - Configuration | 4 | 0 | 4 (T043-T046) | --- ## Ground-rules Alignment | Principle | Status | Evidence | |-----------|--------|----------| | I. Clean Code Standards | PASS | Standards.md defines naming, function length (<30 lines), ruff linting | | II. Test-First Development | PASS | Tasks explicitly require tests FIRST (see task sections) | | III. Code Review Requirements | PASS | Ground-rules mandate PR review before merge | | IV. Documentation Standards | PASS | Docstring requirements in standards.md, quickstart.md in tasks | | V. Continuous Improvement | PASS | Architecture.md §10 tracks technical debt | **Quality Gates Alignment**: - Pre-commit: `.pre-commit-config.yaml` exists with ruff, bandit - Pre-merge: CI workflow defined in standards.md §11.3 - Pre-deploy: Security scan (bandit) configured **No ground-rules violations detected.** --- ## Unmapped Tasks All 52 tasks in tasks.md map to either: - Functional requirements (FR-001 through FR-018) - User stories (US1 through US4) - Infrastructure/setup (Phases 1-2, 7) No orphan tasks detected. --- ## Terminology Consistency | Concept | spec.md | design.md | tasks.md | Recommendation | |---------|---------|-----------|----------|----------------| | Tool name | "get-checklist" (L194) | "get_checklist" | "get_checklist" | Standardize: `get_checklist` | | Tool name | "list-checklists" (L195) | "list_checklists" | "list_checklists" | Standardize: `list_checklists` | | Token location | "~/.sso-mcp-server" | "~/.sso-mcp-server/token_cache.bin" | Same | Consistent | | Default port | "8080" | "8080" | Uses env var | Consistent | | Auth library | "MSAL" | "MSAL" | "msal" | Consistent | --- ## Architecture Alignment | design.md Reference | architecture.md Section | Alignment | |---------------------|------------------------|-----------| | ADR-001 HTTP Streamable | §8.2 ADR-001 | ALIGNED | | ADR-004 MSAL | §8.2 ADR-004 | ALIGNED | | ADR-005 Token persistence | §8.2 ADR-005 | ALIGNED | | Project structure | §6.1 Directory Structure | ALIGNED | | Component organization | §5.1 Component Diagram | ALIGNED | **Note**: Architecture.md has been updated to show token refresh in Auth Manager (manager.py), not a separate refresher.py.
