## Detailed Findings

### T1: Inconsistent Timeout Value References (MEDIUM)

**Location**: spec.md:L73-74 (FR-001), tasks.md:T014

**Issue**: Spec.md FR-001 requires cargo make targets to include "SLOs" in descriptions. Task T014 specifies "<5s target 1.95s measured" for cargo make check, but current Makefile.toml line 22 shows "15s timeout for lock contention". The dogfooding assessment (DOGFOODING_ASSESSMENT.md) identifies that check target should have <5s SLO, not 15s.

**Recommendation**: Update spec.md FR-001 example to clarify: "SLO: <5s target (current implementation: 15s for lock contention handling, target: optimize to 5s)". This aligns spec with actual measured performance while documenting improvement target.

**Impact**: Medium - Affects accuracy of tool documentation and success criteria measurement (SC-001, SC-005).

---

### D1: Evidence Collection Task Mapping (MEDIUM)

**Location**: tasks.md:T054-T060 (Phase 6 Polish)

**Issue**: Phase 6 includes 7 evidence collection tasks that generate validation files for 8 success criteria (SC-001 through SC-008), but the mapping between specific tasks and success criteria is implicit, requiring inference:
- T054 → SC-001 (tool selection accuracy)
- T055 → SC-003 (SLO violations)
- T056 → SC-005 (compile time)
- T057 → SC-004 (skill auto-invocation)
- T060 → SC-002, SC-006, SC-007, SC-008 (all criteria in final report)

**Recommendation**: Add explicit SC mapping comments to each evidence collection task description:
```markdown
- [ ] T054 [P] Collect post-optimization tool selection accuracy evidence [PROVES: SC-001]: Run tool_selection_tests...
- [ ] T055 [P] Collect post-optimization SLO violations [PROVES: SC-003]: cargo make slo-check...
```

**Impact**: Medium - Improves traceability and validation completeness checking during implementation.

---

### U1: Test Utility Module Underspecification (MEDIUM)

**Location**: tasks.md:T009

**Issue**: Task T009 states "Create test utility module in tests/aci/mod.rs for shared test helpers (Makefile.toml parsing, cargo make target listing)" but doesn't specify the exact helper functions needed, their signatures, or what test data structures they should return.

**Recommendation**: Clarify minimum required helpers in task description:
```markdown
- [ ] T009 Create test utility module in tests/aci/mod.rs with functions:
  - `parse_makefile_toml(path: &Path) -> Result<HashMap<String, Target>, Error>` - Parse TOML and extract [tasks.*] sections
  - `list_cargo_make_targets() -> Vec<String>` - Execute `cargo make --list-all-steps` and parse output
  - `extract_description(target_name: &str) -> Option<String>` - Get description field from parsed TOML
  - `validate_description_components(desc: &str) -> ComponentCheck` - Verify 5 components present (purpose, timing, SLO, examples, recovery)
```

**Impact**: Medium - Affects test implementation clarity. Tests T010-T046 depend on this module.

---

### W1: Entity Name Capitalization Inconsistency (LOW)

**Location**: spec.md:L86, data-model.md:L11, tasks.md (various)

**Issue**: The "cargo make Target" entity is capitalized when referring to the formal entity (data-model.md), but lowercase "target" is used in casual references throughout spec.md and tasks.md, creating potential confusion about whether it refers to the entity or a general target.

**Recommendation**: Standardize terminology:
- Use "cargo make Target" (capitalized) when referring to the entity/data model
- Use "cargo make target" (lowercase) when referring to specific instances (e.g., "check target", "test target")
- Update data-model.md header: "1. cargo make Target" → "1. cargo make Target (Entity)"

**Impact**: Low - Style/clarity issue, doesn't affect implementation.

---

### W2: Verbose Task Description Repetition (LOW)

**Location**: tasks.md:T014-T028 (15 tasks)

**Issue**: All 15 Makefile.toml enhancement tasks repeat the phrase "with comprehensive 5-component documentation (purpose: ..., timing: ..., SLO: ..., examples: ..., recovery: ...)" which adds ~150 characters per task, totaling 2,250+ characters of repetitive text.

**Recommendation**: After T014 (first occurrence), use shorthand for remaining tasks:
```markdown
- [ ] T014 [US1] Enhance cargo make check description in Makefile.toml lines 21-25 with comprehensive 5-component documentation (purpose: fast compilation check, timing: before every commit, SLO: <5s target 1.95s measured, examples: GREEN/RED outputs, recovery: fix error and re-run)

- [ ] T015 [US1] Enhance cargo make test description in Makefile.toml lines 291-317 with 5-component docs (all tests with timeouts; before push/PR; 30s/120s escalation; test pass/fail examples; fix failing test)

- [ ] T016 [US1] Enhance cargo make test-unit description in Makefile.toml lines 319-323 with 5-component docs (unit tests fast feedback; during development; <16s; unit test outputs; investigate failures)
```

**Impact**: Low - Readability improvement, doesn't affect implementation correctness.

## Overall Assessment

### Strengths

1. **Perfect Constitution Alignment**: All 9 principles properly addressed with clear N/A justifications where principles don't apply.

2. **100% Requirement Coverage**: Every functional requirement (FR-001 through FR-010) has comprehensive task coverage with explicit test validation.

3. **Independent User Stories**: All 3 user stories can be implemented and tested independently, enabling parallel development and incremental delivery.

4. **Comprehensive Testing Strategy**: Chicago TDD followed rigorously with 16 test tasks (T010-T013, T029-T032, T042-T046) written FIRST before implementation.

5. **Evidence-Based Success Criteria**: All 8 success criteria (SC-001 through SC-008) have quantitative measurements with dedicated evidence collection tasks.

6. **High Parallelization**: 42/60 tasks (70%) marked [P] for parallel execution, enabling efficient team collaboration.

7. **Clear Phase Structure**: 6 phases with explicit dependencies and checkpoints for independent validation.

8. **Excellent Terminology Consistency**: All domain terms (cargo make Target, Andon Signal, Constitution Skill, SLO, Quality Gate) used uniformly across all artifacts.

### Areas for Improvement (Optional)

1. **T1 (MEDIUM)**: Clarify SLO timeout value discrepancy between spec and current implementation (15s vs 5s target).

2. **D1 (MEDIUM)**: Add explicit SC-XXX mapping to evidence collection tasks for clearer traceability.

3. **U1 (MEDIUM)**: Specify exact helper functions needed in test utility module (T009).

4. **W1, W2 (LOW)**: Minor wording/style improvements for clarity and conciseness.

**Recommendation**: These findings are **optional improvements**—the feature is ready for implementation as-is. If desired, address T1, D1, U1 before proceeding to `/speckit.implement` to maximize implementation clarity.

---

## Next Actions

**Status**: ✅ **READY FOR IMPLEMENTATION**

**Recommendation**: **Proceed with `/speckit.implement`**

This feature has:
- ✅ Zero critical issues
- ✅ Zero high issues
- ✅ 100% requirement coverage
- ✅ Perfect constitution alignment
- ✅ Comprehensive testing strategy
- ✅ Clear task breakdown with dependencies

**Optional Pre-Implementation Improvements** (not required):

1. **Address T1**: Update spec.md FR-001 to clarify 15s current vs 5s target SLO for cargo make check
2. **Address D1**: Add explicit `[PROVES: SC-XXX]` markers to evidence collection tasks T054-T060
3. **Address U1**: Expand T009 with specific helper function signatures

**Estimated effort for optional improvements**: 30-45 minutes

**If proceeding immediately**: Run `/speckit.implement` to begin Phase 1 (Setup). All tasks are immediately executable with specific file paths, line ranges, and acceptance criteria.

## Remediation Offer

Would you like me to suggest concrete edit patches for the top 3 MEDIUM issues (T1, D1, U1)? I can provide exact text replacements to apply manually to spec.md and tasks.md before running `/speckit.implement`.

**Note**: These edits are **optional**—the feature is production-ready without them.
