# Pre-Implementation Review

**Feature**: Deep Research Agent Example
**Artifacts reviewed**: spec.md, plan.md, tasks.md, checklists/feature.md, research.md, data-model.md
**Review model**: Claude Opus 4.6
**Generating model**: Claude Opus 4.6 (Phases 1-6)
**Date**: 2026-03-30

## Summary

| Dimension | Verdict | Issues |
|-----------|---------|--------|
| Spec-Plan Alignment | PASS | All 6 user stories addressed. Plan covers all 17 FRs. |
| Plan-Tasks Completeness | PASS | All 11 planned files have corresponding tasks. |
| Dependency Ordering | PASS | Setup -> Content -> Code -> Documentation. Correct. |
| Parallelization Correctness | PASS | [P] markers accurate. Groups respect max-3. |
| Feasibility & Risk | WARN | T008 is large (~150-200 LOC). Stale ANTHROPIC_API_KEY refs fixed. |
| Standards Compliance | PASS | Constitution is blank template. |
| Implementation Readiness | PASS | All warnings resolved. Tasks have exact file paths. |

**Overall**: READY

## Warnings Resolved

1. W1 - Removed stale ANTHROPIC_API_KEY from T003 and plan.md (Bedrock uses AWS credentials)
2. W2 - Fixed spec US1 acceptance scenario: langchain-anthropic -> langchain-aws
3. W3 - T008 size noted but acceptable for single-file agent definition
4. W4 - Removed [US1] label from T011 (cross-cutting documentation)
5. SC-005 qualified with "in LangGraph Studio mode"

## Observations

1. Phases 4-8 have no implementation tasks — US2-US6 are delivered by graph.py configuration
2. supports_cache_control=True for prompt caching included in FR-008
3. CLI mode HITL limitation documented in research.md R5 and now reflected in SC-005
