## Next Phase

All planned phases are complete. No pending work remains.

## Completed (Phase 4)

All five MCP tool handlers are complete:

| Handler | File | Tests |
|---------|------|-------|
| handleAskChatGpt | `src/tools/ask-chatgpt.js` | ✅ 27 |
| handleReviewPlan | `src/tools/review-plan.js` | ✅ 28 |
| handleReviewCode | `src/tools/review-code.js` | ✅ 28 |
| handleDebugIssue | `src/tools/debug-issue.js` | ✅ 28 |
| handleArchitectureReview | `src/tools/architecture-review.js` | ✅ 28 |

Total: 139 orchestration-only tests, all passing.

## Completed (Phase 5)

**All five MCP tools registered:** ask_chatgpt, review_plan, review_code, debug_issue, architecture_review.

## Completed (Phase 6) — Provider Abstraction ✅

Decoupled tool handlers from OpenAI implementation via a provider abstraction layer:

### src/providers/factory.js
- `createChatProvider(config)` validates `chatgptMcpProvider` against whitelist
- Defaults to `"openai"` for any falsy/unknown value (null, NaN, numeric)
- Throws with descriptive message on unrecognized provider names

### src/providers/openai.js
- `openaiProvider.send(input, config)` — thin adapter wrapping OpenAI modules
- Internally calls `createOpenAIClient(config)` then `sendOpenAIResponse(client, params)`
- Params include: input as system messages array, model, temperature, maxOutputTokens from config

### Handler changes (all 5)
- Old interface: `{ loadConfig, createOpenAIClient, sendOpenAIResponse }`
- New interface: `{ loadConfig, createProvider }`
- Each handler calls `provider = deps.createProvider(config)` then `provider.send(budget.input, config)`
- Handler logic unchanged — only dependency injection changed

### CHATGPT_MCP_PROVIDER env var
- Defaults to `"openai"` when not set
- Accepts any string at loadConfig time; validation happens in factory at provider creation
- Currently only `"openai"` is whitelisted; others throw at createChatProvider() time

## Completed (Phase 7) — Tests ✅

### Handler tests updated (5 files, all using `{ loadConfig, createProvider }` mock pattern)
| File | Tests | Status |
|------|-------|--------|
| test/tools/ask-chatgpt.test.js | 27 | ✅ |
| test/tools/review-plan.test.js | 28 | ✅ |
| test/tools/review-code.test.js | 28 | ✅ |
| test/tools/debug-issue.test.js | 28 | ✅ |
| test/tools/architecture-review.test.js | 28 | ✅ |

### New provider/config tests (3 files)
| File | Tests | Status |
|------|-------|--------|
| test/providers/factory.test.js | ~30 | ✅ covers default, whitelist, edge cases |
| test/providers/openai.test.js | 27 | ✅ covers all send delegation paths |
| test/config/env.test.js | +4 (added section) | ✅ covers chatgptMcpProvider env var |

### Final verification (Phase 7)
- All 579 tests pass across 20 test files (end of Phase 7)

### Post-multiphase verification
- All 706 tests pass across 22 test files (all phases complete)
- `npm start` → tools/list shows same 5 tools, unchanged schemas
- Zero regression in existing test coverage

## Completed (Phase 8) — Manual Export Provider ✅

### src/providers/manual-export.js
- `manualExportProvider.send(request, config)` — zero-API-cost provider
- Wraps pre-built prompt in copy/paste-ready format for ChatGPT Web (`https://chatgpt.com`)
- Detects tool name from input fields: `debug_issue`, `review_code`, `architecture_review`, `review_plan`, `ask_chatgpt`
- Adds box-delimited display with `│` prefixes, corner delimiters (┌ ┐ └ ┘)
- Includes instructions section (5 numbered steps), metadata section (tool, provider, length)
- Warns on prompts over 30k characters
- Handles empty/missing prompt gracefully with advisory message
- Preserves unicode, markdown code blocks, JSON, special HTML characters exactly

### Factory integration
- `"manual"` added to SUPPORTED_PROVIDERS whitelist in `src/providers/factory.js`
- `CHATGPT_MCP_PROVIDER=manual` switches all tool handlers to manual export mode
- Defaults to `"openai"` when not set — OpenAI behaviour unchanged
- Same provider interface: `{ send(request, config) => Promise<{ content: string }> }`

### Tests added (Phase 8)
| File | Tests | Coverage |
|------|-------|----------|
| test/providers/manual-export.test.js | 56 | structure, tool detection, unicode, long prompts, edge cases, repeatability, visual layout |
| test/providers/factory.test.js | +9 manual provider tests | factory integration with "manual" |

### Final verification (Phase 8)
- All 706 tests pass across 22 test files, zero regressions
- `npm start` → tools/list shows same 5 tools, unchanged schemas
- No `chat.openai.com` references in codebase — only `chatgpt.com`
- MCP initialize handshake succeeds with chatgpt-mcp v0.1.0

## Completed (Phase 10) — Ollama Provider ✅

### src/providers/ollama.js
- `ollamaProvider.send(reviewRequest, config)` — local AI provider using Ollama `/api/chat` endpoint
- Uses native `fetch()` for HTTP calls — zero new dependencies
- Implements same provider interface as openai and manual: `{ send(request, config) => Promise<{ content: string }> }`

### Provider details
- **Request format**: OpenAI-compatible chat API (`model`, `messages`, `stream`, `options`)
- **Response parsing**: Extracts `data.message.content` from Ollama response
- **Error categories**: `OllamaTimeoutError`, `OllamaModelNotFoundError` (404), `OllamaValidationError` (422), `OllamaApiNotAvailableError` (501), `OllamaRequestError` (fallback)
- **Base URL normalization**: Strips trailing slashes for safe path concatenation

### Environment variables
| Variable | Default | Description |
|----------|---------|-------------|
| `OLLAMA_BASE_URL` | `http://localhost:11434` | Ollama API endpoint |
| `OLLAMA_MODEL` | `qwen3:latest` | Model name for chat requests |
| `OLLAMA_TEMPERATURE` | `0.2` | Sampling temperature |
| `OLLAMA_TIMEOUT` | `60` | Request timeout in seconds |

### Factory integration
- `"ollama"` added to SUPPORTED_PROVIDERS whitelist in `src/providers/factory.js`: `Set(["openai", "manual", "ollama"])`
- `CHATGPT_MCP_PROVIDER=ollama` switches all tool handlers to local Ollama mode
- Defaults to `"openai"` when not set — OpenAI behaviour unchanged
- Same provider interface as openai and manual providers

### Current provider status
| Provider | Env Value | Type | Requires API key? |
|----------|-----------|------|-------------------|
| `openai` | `CHATGPT_MCP_PROVIDER=openai` | Cloud (OpenAI Responses API) | Yes (`OPENAI_API_KEY`) |
| `manual` | `CHATGPT_MCP_PROVIDER=manual` | Local (copy-paste) | No |
| `ollama` | `CHATGPT_MCP_PROVIDER=ollama` | Local (Ollama /api/chat) | No |

### Task 5.1 through 5.5 - MCP Server and Tool Registration ✅

**All five MCP tools registered:** ask_chatgpt, review_plan, review_code, debug_issue, architecture_review.

Key details from Phase 5:
- MCP stdio server in `src/server.js` with initialize handshake ✅
- All tools use shared `baseInputSchema` with dependency injection via `{ loadConfig, createProvider }` (Phase 6)
- Error formatting normalized — single "Error:" prefix across all tools ✅
- Claude Code discovery configured via `.claude/settings.local.json` ✅

## Completed (Task 10.3) — Local Setup Helper ✅

### scripts/setup.js
- Interactive onboarding helper (~280 lines, zero dependencies, Node.js built-ins only)
- Provider selection: `[1] openai`, `[2] manual`, `[3] ollama`
- Provider-specific prompts (OpenAI API key with masked input; Ollama URL, model, temperature, timeout)
- Clean `.env` file generation with confirmation prompt
- Preserves non-conflicting keys in existing `.env` files
- Optional `.claude/settings.local.json` creation with MCP server config
- Graceful non-TTY handling (visible input mode warning)
- No network calls, no secrets printed, user-confirmation required

### Files added/modified
| File | Action | Purpose |
|------|--------|---------|
| `scripts/setup.js` | Created | Interactive setup helper |
| `test/setup/setup.test.js` | Created | 33 tests (provider validation, config generation, file I/O) |
| `docs/SETUP.md` | Created | Full documentation for the setup helper |
| `package.json` | Modified | Added `"setup": "node scripts/setup.js"` script |
| `README.md` | Modified | Quick-start section + test count update |
| `TASKS.md` | Modified | Phase 10 entry and Task 10.3 details |
| `PROJECT_STATE.md` | Modified | Test count updated to 701/22 files |

### Test results (Task 10.3)
- **Before:** 668 tests across 21 test files
- **After:** 706 tests across 22 test files (+38 new)
- All passing, zero regressions

### Smoke tests
- `npm run setup` — starts and runs in non-TTY mode ✅
- MCP initialize → `chatgpt-mcp` v0.1.0 ✅
- MCP tools/list → 5 tools with correct schemas ✅

## General Rules

- Read ARCHITECTURE.md before making changes.
- Work incrementally.
- Keep changes small.
- Do not implement multiple phases at once.
- Do not add features not described in ARCHITECTURE.md.
- Update documentation when appropriate.
- Claude Code is the implementation agent.
- ChatGPT MCP is advisory only.
