Phase 3 Completion Summary

Phase 3 — Tool Inputs and Prompts — is now complete.

Completed prompt builders:

• buildBasePrompt — base system prompt (ARCHITECTURE.md §11)
• buildAskChatGptPrompt — general second-opinion advisor
• buildReviewPlanPrompt — plan review before implementation
• buildReviewCodePrompt — focused code/diff review
• buildDebugIssuePrompt — error/log/stack trace analysis
• buildArchitectureReviewPrompt — architecture decision trade-off review

What Phase 3 established:

• Prompt layer complete with composition pattern established.
• All prompt builders tested (56 tests for architecture-review alone; 384 total).
• Each builder follows the same pattern: buildBasePrompt() → \n\n---\n\n → tool-specific section.
• Guard rails reinforced in every builder (Claude Code is executor; ChatGPT is advisory only).

Not done yet (belongs to Phase 4):

• No MCP tool registration.
• No tool handlers.

Completed Tasks (Phase 4)

Task 4.1 — ask_chatgpt MCP Tool Handler ✅

Implemented src/tools/ask-chatgpt.js with dependency-injected handler and 27 orchestration-only tests in test/tools/ask-chatgpt.test.js.

Key design decisions:

• Execution order: validate → loadConfig → checkContextBudget → buildAskChatGptPrompt → createOpenAIClient → sendOpenAIResponse
• All external deps injected (loadConfig, createOpenAIClient, sendOpenAIResponse); internal utilities imported directly
• OpenAI errors pass through String(err) unchanged — no wrapping or reformatting
• Budget check short-circuits before prompt building or client creation
• Every path returns structured { ok, answer|error, warnings } — never throws to caller
• 27 tests covering: success path, validation failure, config failure, budget failure, client creation failure, OpenAI failure, dependency call order, error handling for null/string throws, warning propagation, result shape, and short-circuit behavior

Task 4.2 — review_plan MCP Tool Handler ✅

Implemented src/tools/review-plan.js with dependency-injected handler and 28 orchestration-only tests in test/tools/review-plan.test.js.

Key design decisions:

• Execution order: validate → loadConfig → checkContextBudget → buildReviewPlanPrompt → createOpenAIClient → sendOpenAIResponse
• All external deps injected (loadConfig, createOpenAIClient, sendOpenAIResponse); internal utilities imported directly
• OpenAI errors pass through String(err) unchanged — no wrapping or reformatting
• Budget check short-circuits before prompt building or client creation
• Every path returns structured { ok, answer|error, warnings } — never throws to caller
• 28 tests mirroring 4.1 structure with one additional test verifying buildReviewPlanPrompt is called with budget.input

Next pending task:

• Task 4.3 — review_code tool handler (src/tools/review-code.js, test/tools/review-code.test.js)

Not done yet (Phase 4):

• No MCP tool registration
• Other tool handlers (review_code, debug_issue, architecture_review)
