fix: ensure agents submodules are registered in sys.modules

- Remove module-level placeholders that prevented __getattr__ from being called - Explicitly import utility functions from agents.utils - Fix __dir__ to include standard module attributes - Ensure submodules (coder, planner, session, memory_manager) are properly registered in sys.modules when accessed via __getattr__ This fixes the test_lazy_import_run_autonomous_agent test and similar lazy import tests that verify submodules are registered in sys.modules. Fixes: test failure in test_agents_init.py
fix: resolve all CodeQL alerts and CodeRabbit review feedback

 This file provides guidance to Claude Code when working with this repository.

-Auto Claude is an autonomous multi-agent coding framework that plans, builds, and validates software for you. It's a TypeScript-first Electron desktop application with a self-contained AI agent layer (Vercel AI SDK v6). A lightweight Python sidecar provides the optional Graphiti memory system.
+Auto Claude is an autonomous multi-agent coding framework that plans, builds, and validates software for you. It's a monorepo with a Python backend (CLI + agent logic) and an Electron/React frontend (desktop UI).

 ## Critical Rules

-**Vercel AI SDK only** — All AI interactions use the Vercel AI SDK v6 (`ai` package) via the TypeScript agent layer in `apps/desktop/src/main/ai/`. NEVER use `@anthropic-ai/sdk` or `anthropic.Anthropic()` directly. Use `createProvider()` from `ai/providers/factory.ts` and `streamText()`/`generateText()` from the `ai` package. Provider-specific adapters (e.g., `@ai-sdk/anthropic`, `@ai-sdk/openai`) are managed through the provider registry.
+**Claude Agent SDK only** — All AI interactions use `claude-agent-sdk`. NEVER use `anthropic.Anthropic()` directly. Always use `create_client()` from `core.client`.

-**i18n required** — All frontend user-facing text uses `react-i18next` translation keys. Hardcoded strings in JSX/TSX break localization for non-English users. Add keys to both `en/*.json` and `fr/*.json`.

+**No time estimates** — Never provide duration predictions. Use priority-based ordering instead.

-**PR target** — Always target the `develop` branch for PRs, not `main`. Main is reserved for releases.
-
-**No console.log in production code** — `console.log` output is invisible in bundled Electron apps. Use Sentry for error tracking in production; reserve `console.log` for development only.

-## Work Approach: Orchestrator-First
-
-You are an orchestrator. Your primary role is to understand what needs to be done, break it into workstreams, and delegate execution to agent teams. This keeps your context window focused on coordination and decision-making rather than filling up with implementation details.
-
-<orchestrator_pattern>
-When given a task, follow this pattern:
-
-1. **Investigate first** — Read the actual code before forming any hypothesis. Use targeted searches (Glob, Grep, Read) for simple lookups. For broader exploration, spawn an Explore agent.
-
-2. **Plan the approach** — Identify what needs to change, which files are involved, and whether work can be parallelized. For multi-step tasks, create a task list to track workstreams.
-
-3. **Delegate execution** — Spawn agent teams to do the implementation work. Each agent gets a clear, self-contained assignment with all the context it needs: relevant file paths, the specific change to make, and acceptance criteria. Run independent workstreams in parallel.
-
-4. **Verify and integrate** — Review agent outputs, run tests, and ensure changes work together. Fix integration issues or spawn follow-up agents as needed.
-</orchestrator_pattern>
-
-**When to delegate vs. do directly:**
- Delegate: multi-file changes, research across the codebase, independent parallel workstreams, tasks that would consume significant context
- Do directly: single-file edits, simple bug fixes, quick lookups, tasks where you already have the context
-
-**Giving agents good assignments** — Each agent works with a fresh context. Include: the specific goal, relevant file paths, code patterns to follow, and what "done" looks like. Agents perform better with explicit, complete instructions than with vague references to "the current task."
-
-**Minimal changes only** — Prefer the simplest approach (e.g., prompt-only changes, single guard clause) before suggesting multi-component solutions. If the user asks for X, implement X — don't bundle additional fixes they didn't request.
-
-**Default to action** — When the user's intent implies making changes, implement them rather than only suggesting. If something is unclear, read the relevant code to fill in the gaps rather than asking. Only ask when genuine ambiguity remains about what the user wants.
-
-## Context Management
-
-Your context window will be automatically compacted as it approaches its limit, allowing you to continue working indefinitely. Do not stop tasks early due to context concerns — instead, persist progress and keep going.
-
-**For long-running tasks:** Use git commits, task lists, and structured notes to track state. When context compacts, review git log and any progress files to re-orient. Focus on incremental progress — complete one component before moving to the next, and commit working states along the way.
-
-**Parallel tool calls** — When reading multiple files, running independent searches, or executing unrelated commands, make all calls in parallel rather than sequentially. This significantly speeds up investigation and implementation.
-
-## Known Gotchas
-
-**Electron path resolution** — For bug fixes in the Electron app, check path resolution differences between dev and production builds (`app.isPackaged`, `process.resourcesPath`). Paths that work in dev often break when Electron is bundled for production — verify both contexts.
-
-### Resetting PR Review State
-
-To fully clear all PR review data so reviews run fresh, delete/reset these three things in `.auto-claude/github/`:
-
-1. `rm .auto-claude/github/pr/logs_*.json` — review log files
-2. `rm .auto-claude/github/pr/review_*.json` — review result files
-3. Reset `pr/index.json` to `{"reviews": [], "last_updated": null}`
-4. Reset `bot_detection_state.json` to `{"reviewed_commits": {}}` — this is the gatekeeper; without clearing it, the bot detector skips already-seen commits
+**PR target** — Always target the `develop` branch for PRs to AndyMik90/Auto-Claude, NOT `main`.

-## AI Agent Layer (`apps/desktop/src/main/ai/`)
+## Backend Development

-All AI agent logic lives in TypeScript using the Vercel AI SDK v6. This replaces the previous Python `claude-agent-sdk` integration.
+### Claude Agent SDK Usage

-### Architecture Overview
+Client: `apps/backend/core/client.py` — `create_client()` returns a configured `ClaudeSDKClient` with security hooks, tool permissions, and MCP server integration.

- **Provider Layer** (`providers/`) — Multi-provider support via `createProviderRegistry()`. Supports Anthropic, OpenAI, Google, Bedrock, Azure, Mistral, Groq, xAI, and Ollama. Provider-specific transforms handle thinking token normalization and prompt caching.
- **Session Runtime** (`session/`) — `runAgentSession()` uses `streamText()` with `stopWhen: stepCountIs(N)` for agentic tool-use loops. Includes error classification (429/401/400) and progress tracking.
- **Worker Threads** (`agent/`) — Agent sessions run in `worker_threads` to avoid blocking the Electron main process. The `WorkerBridge` relays `postMessage()` events to the existing `AgentManagerEvents` interface.
- **Build Orchestration** (`orchestration/`) — Full planner → coder → QA pipeline. Parallel subagent execution via `Promise.allSettled()`.
- **Tools** (`tools/`) — 8 builtin tools (Read, Write, Edit, Bash, Glob, Grep, WebFetch, WebSearch) defined with Zod schemas via AI SDK `tool()`.
- **Security** (`security/`) — Bash validator, command parser, and path containment ported from Python with identical allowlist behavior.
- **Config** (`config/`) — `AGENT_CONFIGS` registry (25+ agent types), phase-aware model resolution, thinking budgets.
+Model and thinking level are user-configurable (via the Electron UI settings or CLI override). Use `phase_config.py` helpers to resolve the correct values:

-### Key Patterns
+```python
+from core.client import create_client
+from phase_config import get_phase_model, get_phase_thinking_budget

-```typescript
-// Agent session using streamText()
-import { streamText, stepCountIs } from 'ai';
+# Resolve model/thinking from user settings (Electron UI or CLI override)
+phase_model = get_phase_model(spec_dir, "coding", cli_model=None)
+phase_thinking = get_phase_thinking_budget(spec_dir, "coding", cli_thinking=None)

-const result = streamText({
-  model: provider,
-  system: systemPrompt,
-  messages: conversationHistory,
-  tools: toolRegistry.getToolsForAgent(agentType),
-  stopWhen: stepCountIs(1000),
-  onStepFinish: ({ toolCalls, text, usage }) => {
-    progressTracker.update(toolCalls, text);
-  },
-});
+client = create_client(
+    project_dir=project_dir,
+    spec_dir=spec_dir,
+    model=phase_model,
+    agent_type="coder",          # planner | coder | qa_reviewer | qa_fixer
+    max_thinking_tokens=phase_thinking,
+)

-// Tool definition with Zod schema
-import { tool } from 'ai';
-import { z } from 'zod';
-
-const readTool = tool({
-  description: 'Read a file from the filesystem',
-  inputSchema: z.object({
-    file_path: z.string(),
-    offset: z.number().optional(),
-    limit: z.number().optional(),
-  }),
-  execute: async ({ file_path, offset, limit }) => { /* ... */ },
-});
+# Run agent session (uses context manager + run_agent_session helper)
+async with client:
+    status, response = await run_agent_session(client, prompt, spec_dir)
 ```

 ### Memory System (Graphiti)

-Graph-based semantic memory accessed via a Python MCP sidecar (lives outside `apps/desktop/`). The AI layer connects to it via `createMCPClient` from `@ai-sdk/mcp`. Configured through the Electron app's onboarding/settings UI. See [ARCHITECTURE.md](shared_docs/ARCHITECTURE.md#memory-system) for details.

-
-### 1.1 Active Polling Endpoint
-
-```
-GET https://chatgpt.com/backend-api/wham/usage
-```
-
-Fallback (when base URL doesn't contain `/backend-api`):
-```
-GET {base_url}/api/codex/usage

-
-**Required Headers:**
-```http
-Authorization: Bearer <access_token>
-ChatGPT-Account-Id: <account_id>
-Content-Type: application/json
-Accept: application/json

-
- `access_token` — The OAuth access token from `auth.openai.com` (same token our `codex-oauth.ts` already obtains)
- `account_id` — Account UUID from OAuth token data. Stored in `~/.codex/auth.json` under `tokens.account_id`. Optional per CodexBar ("when available") but may be required.

-
-### 1.3 Passive Headers (From API Responses)
-
-Rate limit data is also returned in HTTP response headers on every `/v1/responses` call:
-
-```
-x-codex-primary-used-percent         → float (e.g., "25.0")
-x-codex-primary-window-minutes       → integer (e.g., "300" for 5h)
-x-codex-primary-reset-at             → unix timestamp seconds
-x-codex-secondary-used-percent       → float (weekly)
-x-codex-secondary-window-minutes     → integer
-x-codex-secondary-reset-at           → unix timestamp seconds
-x-codex-credits-has-credits          → "true" or "false"
-x-codex-credits-unlimited            → "true" or "false"
-x-codex-credits-balance              → decimal string e.g. "9.99"
-```
-
-SSE event type `codex.rate_limits` also carries this data inline in streaming responses.
-
-### 1.4 Token Details
-
-Our `codex-oauth.ts` already uses the correct flow:
- **Client ID:** `app_EMoamEEZ73f0CkXaXp7hrann` (same as Codex CLI)
- **Auth endpoint:** `https://auth.openai.com/oauth/authorize`
- **Token endpoint:** `https://auth.openai.com/oauth/token`
- **Scopes:** `openid profile email offline_access`
- **Refresh:** `POST https://auth.openai.com/oauth/token` with `grant_type=refresh_token`
-
-**Missing:** `account_id` for the `ChatGPT-Account-Id` header. Options:
-1. Decode from the JWT access token
-2. Read from `~/.codex/auth.json` (`tokens.account_id`)
-3. Extract during OAuth token exchange (may be in response)
-4. Try without it first (optional per CodexBar docs)
-

-
-## 2. Current System Architecture
-
-### 2.1 Two Parallel Account Systems
-
-The app has TWO account management systems that don't fully integrate:
-
-**System A: Legacy Claude Profile Manager (Main Process)**
- `claude-profile-manager.ts` — Manages OAuth profiles, rate limits, usage, auto-swap
- `claude-profiles.json` — Stores profiles with `activeProfileId`, `accountPriorityOrder`
- `usage-monitor.ts` — Polls Anthropic's `/api/oauth/usage` endpoint every 30s
- `token-refresh.ts` — Refreshes tokens via `console.anthropic.com/v1/oauth/token`
- `rate-limit-detector.ts` — Detects rate limits, triggers auto-swap
- `profile-scorer.ts` — Scores profiles by availability for auto-swap
- **100% Anthropic-specific.** Only knows about Anthropic OAuth tokens, Anthropic endpoints, Anthropic keychain format.
-
-**System B: Multi-Provider Accounts (Renderer + Settings)**
- `ProviderAccount[]` in `settings-store.ts` — All connected accounts (any provider)
- `globalPriorityOrder: string[]` in AppSettings — Manual priority queue
- `useActiveProvider()` hook — First account in priority order = active
- **Provider-agnostic.** Works for all 10 providers. But has NO usage monitoring, NO auto-swap.
-
-**The gap:** System A handles usage monitoring + auto-swap but only for Anthropic. System B handles multi-provider accounts but has no usage awareness.
-
-### 2.2 Data Flow: Usage Polling
-
-```
-UsageMonitor.start() → 30s interval
-  ↓
-checkUsageAndSwap()
-  ├─ determineActiveProfile()           ← Hardcoded: defaults to anthropic baseUrl
-  ├─ getCredential()                    ← Hardcoded: reads from Anthropic keychain
-  │   └─ ensureValidToken(configDir)    ← Hardcoded: refreshes via Anthropic endpoint
-  ├─ fetchUsageViaAPI()                 ← Hardcoded: only allows anthropic/zai/zhipu domains
-  │   ├─ getUsageEndpoint(provider)     ← Only 3 providers configured
-  │   ├─ Add anthropic-specific headers ← if (provider === 'anthropic') add beta headers
-  │   └─ Parse response                ← Provider-specific normalization
-  ├─ emit('usage-updated')             → IPC 'claude:usageUpdated' → renderer
-  ├─ emit('all-profiles-usage-updated') → IPC 'claude:allProfilesUsageUpdated' → renderer
-  └─ checkThresholdsExceeded()
-     └─ performProactiveSwap()          ← Only swaps Anthropic profiles

-  → profileManager.setActiveProfile()      ← Only updates claude-profiles.json
-  → usageMonitor.getAllProfilesUsage()     ← Refreshes UI

-```
-
-**Problem:** Auto-swap updates `claude-profiles.json` but NOT `globalPriorityOrder`. The renderer's priority queue may be out of sync.
-
-### 2.4 UI Components
-
-| Component | What it shows | Provider-specific? |
-|---|---|---|
-| `AuthStatusIndicator` | Provider badge (OpenAI/Anthropic) + auth type label | Codex = green "Codex", Anthropic = orange "OAuth" |
-| `UsageIndicator` | Usage bars OR "Subscription" OR "Unlimited" | Anthropic OAuth = bars, Codex OAuth = "Subscription", API = "Unlimited" |
-| `ProviderAccountCard` | Account card in settings with usage bars | Shows usage bars only when `account.usage` populated (Anthropic only) |
-| `ProviderAccountsList` | All accounts grouped by provider | Generic, but re-auth routes differ per provider |
-| `AddAccountDialog` | OAuth flow + account creation | Different flows: Codex → `codexAuthLogin()`, Anthropic → `claudeAuthLoginSubprocess()` |
-| `ProviderSection` | Provider group with "Add" buttons | Button label: "Add Codex Subscription" vs "Add OAuth" |
-
-### 2.5 Type Naming
-
-Types use "Claude" prefix but are structurally generic:
-```typescript
-ClaudeUsageSnapshot    → { sessionPercent, weeklyPercent, resetTimestamps, profileId, ... }
-ClaudeUsageData        → { sessionUsagePercent, weeklyUsagePercent }
-ClaudeRateLimitEvent   → { type, hitAt, resetAt }
-ProfileUsageSummary    → { sessionPercent, weeklyPercent, availabilityScore, ... }
-AllProfilesUsage       → { activeProfile, allProfiles[], fetchedAt }
-```
-
-These types work perfectly for Codex data — same session/weekly model. No structural changes needed, just need to populate them.
-

-
-## 3. Anthropic-Hardcoded Locations
-
-### 3.1 CRITICAL — Must Change
-
-| File | Line(s) | What's hardcoded | What to do |
-|---|---|---|---|
-| `usage-monitor.ts:45-49` | `ALLOWED_USAGE_API_DOMAINS` | Only `api.anthropic.com`, `api.z.ai`, `open.bigmodel.cn` | Add `chatgpt.com` |
-| `usage-monitor.ts:60-73` | `PROVIDER_USAGE_ENDPOINTS` | Only anthropic/zai/zhipu paths | Add `{ provider: 'openai', usagePath: '/wham/usage' }` |
-| `usage-monitor.ts:662,1069,1346,1359` | `baseUrl: 'https://api.anthropic.com'` | Hardcoded fallback for all OAuth profiles | Detect provider from account, use `chatgpt.com/backend-api` for Codex |
-| `usage-monitor.ts:1424` | `if (provider === 'anthropic')` adds beta headers | Anthropic-specific `anthropic-beta` header | Add `else if (provider === 'openai')` to add `ChatGPT-Account-Id` header |
-| `token-refresh.ts:31` | `ANTHROPIC_TOKEN_ENDPOINT = 'https://console.anthropic.com/v1/oauth/token'` | Only Anthropic refresh endpoint | Route to `auth.openai.com/oauth/token` for Codex |
-| `token-refresh.ts:37` | `CLAUDE_CODE_CLIENT_ID = '9d1c250a-...'` | Only Anthropic client ID | Use `app_EMoamEEZ73f0CkXaXp7hrann` for Codex |
-| `UsageIndicator.tsx:118` | `provider === 'anthropic' && authType === 'oauth'` | Only Anthropic gets usage bars | Add `\|\| provider === 'openai'` |
-
-### 3.2 MODERATE — Should Change
-
-| File | Line(s) | What's hardcoded | What to do |
-|---|---|---|---|
-| `usage-monitor.ts:1040-1072` | `determineActiveProfile()` | Returns `baseUrl: 'https://api.anthropic.com'` for all OAuth | Detect provider, return `chatgpt.com/backend-api` for Codex |
-| `credential-utils.ts` | Keychain service names | `"Claude Code-credentials"` | Codex tokens stored differently (file-based, not keychain) |
-| `usage-monitor.ts:1513` | `if (provider === 'zai' \|\| provider === 'zhipu')` | Provider-specific response unwrapping | Add Codex response parsing (different JSON structure) |
-| `rate-limit-detector.ts:14` | `RATE_LIMIT_PATTERN` | Claude-specific: `"Limit reached · resets..."` | Add Codex-specific patterns |
-| IPC channel names | `'claude:usageUpdated'`, `'claude:allProfilesUsageUpdated'` | "claude" prefix | Cosmetic — rename to `'usage:updated'` etc. (optional, low priority) |
-
-### 3.3 LOW PRIORITY — Nice to Have
-
-| Item | What | Why low priority |
-|---|---|---|
-| Type naming | `ClaudeUsageSnapshot` → `UsageSnapshot` | Structural refactor, types work as-is for Codex |
-| IPC method names | `requestUsageUpdate` returns `ClaudeUsageSnapshot` | Works fine, just naming |
-| `claudeProfileId` on `ProviderAccount` | Only used for Anthropic OAuth | Codex doesn't need it |
-
---
-
-## 4. Provider-Agnostic Parts
-
-These components already work for any provider and need NO changes:
-
-| Component/Module | Why it's already generic |
-|---|---|
-| `profile-scorer.ts` | Scores by `billingModel`, usage thresholds, rate limit events — no provider checks |
-| `rate-limit-manager.ts` | Stores/checks rate limit events — pure data, no provider logic |
-| `operation-registry.ts` | Tracks running operations — no provider awareness |
-| `ProviderAccount` type | Has `provider` field, `billingModel`, `usage` — works for any provider |
-| `globalPriorityOrder` | Array of account IDs — provider-agnostic ordering |
-| `useActiveProvider()` hook | Returns first account in priority order — generic |
-| `ProviderAccountCard` | Shows usage bars when `account.usage` is populated — will work for Codex once data flows |
-| `AddAccountDialog` | Already has separate Codex OAuth flow |
-| `AuthStatusIndicator` | Already shows Codex-specific green badge |
-| All i18n keys | Codex-specific labels already exist |
-

-
-## 5. Implementation Plan
-
-### Phase 1: Codex Usage Fetcher (Core)
-
-Create `apps/desktop/src/main/claude-profile/codex-usage-fetcher.ts`:
-
-```typescript
-// Responsibilities:
-// 1. Read Codex OAuth token (from our codex-auth.json)
-// 2. Read account_id (from ~/.codex/auth.json or JWT decode)
-// 3. Call GET https://chatgpt.com/backend-api/wham/usage
-// 4. Parse response into ClaudeUsageSnapshot format
-// 5. Handle 401 → refresh token via codex-oauth.ts
-// 6. Handle 403 → mark as needsReauthentication
-```
-
-**Key function:**
-```typescript
-async function fetchCodexUsage(accessToken: string, accountId?: string): Promise<ClaudeUsageSnapshot>
-```
-
-### Phase 2: Wire into Usage Monitor
-
-Modify `usage-monitor.ts`:
-
-1. Add `chatgpt.com` to `ALLOWED_USAGE_API_DOMAINS`
-2. Add Codex to `PROVIDER_USAGE_ENDPOINTS`
-3. Update `determineActiveProfile()` to detect Codex accounts from `globalPriorityOrder`
-4. Update `getCredential()` to read Codex OAuth token (from `codex-auth.json`)
-5. Update `fetchUsageViaAPI()` to handle Codex response format
-6. Add Codex-specific headers (`ChatGPT-Account-Id`)
-7. Add Codex response parsing (different JSON structure than Anthropic)
-
-### Phase 3: Token Refresh Routing
-
-Modify `token-refresh.ts` or create parallel Codex path:
-
- When refreshing a Codex token, use `auth.openai.com/oauth/token` with Codex client ID
- When refreshing an Anthropic token, use `console.anthropic.com/v1/oauth/token` with Claude client ID
- Provider detection: check the account's `provider` field, or detect from token prefix
-
-### Phase 4: UI Updates
-
-1. `UsageIndicator.tsx:118` — Add `|| provider === 'openai'` to `hasUsageMonitoring`
-2. That's it — the rest of the UI already handles usage bars, reset times, multi-profile display generically
-
-### Phase 5: Auto-Swap for Codex
-
-1. Add Codex-specific rate limit patterns to `rate-limit-detector.ts`
-2. Codex returns `"codexErrorInfo": "UsageLimitExceeded"` on limit hit
-3. Auto-swap logic in `profile-scorer.ts` already works — it just needs usage data populated

-## Appendix: Comparison Table
-
-| Aspect | Anthropic (Claude Code) | OpenAI (Codex) |
-|---|---|---|
-| **Usage endpoint** | `api.anthropic.com/api/oauth/usage` | `chatgpt.com/backend-api/wham/usage` |
-| **Auth header** | `Bearer <oauth_token>` | `Bearer <access_token>` + `ChatGPT-Account-Id` |
-| **Session window** | ~5h | Configurable (`limit_window_seconds`) |
-| **Weekly window** | 7 days | Configurable (`limit_window_seconds`) |
-| **Token source** | Keychain (`Claude Code-credentials`) | File (`codex-auth.json`) |
-| **Token refresh** | `console.anthropic.com/v1/oauth/token` | `auth.openai.com/oauth/token` |
-| **Client ID** | `9d1c250a-e61b-44d9-88ed-5944d1962f5e` | `app_EMoamEEZ73f0CkXaXp7hrann` |
-| **Passive tracking** | Not available | `x-codex-*` response headers |
-| **Rate limit error** | `"Limit reached · resets Dec 17..."` | `"codexErrorInfo": "UsageLimitExceeded"` |
-| **Profile isolation** | `~/.claude-profiles/{name}/` dirs | Single `codex-auth.json` file |
-| **Multi-account** | Multiple config dirs in keychain | Single file (no multi-account yet) |
-
-## Appendix: Caveats
-
-1. **Undocumented API** — `chatgpt.com/backend-api/wham/usage` is internal. The Codex CLI depends on it, so it's unlikely to break silently.
-2. **Account ID** — May be required. Test without it first. If needed, decode from JWT or read `~/.codex/auth.json`.
-3. **CORS** — Not an issue (Electron main process = Node.js).
-4. **Polling rate** — Unknown if OpenAI rate-limits `wham/usage`. Start conservatively (every 30-60s).
-5. **Multi-account Codex** — Codex CLI doesn't support multiple accounts. We store one token file. If user has multiple Codex accounts, they'd need to re-auth each time (unlike Anthropic which supports multiple config dirs).

 ## Development Setup

-The project is a single Electron desktop application in `apps/desktop/`. All AI agent logic lives in TypeScript using the Vercel AI SDK v6.
+The project consists of two main components:

-From the repository root:
+1. **Python Backend** (`apps/backend/`) - The core autonomous coding framework
+2. **Electron Frontend** (`apps/frontend/`) - Desktop UI
+
+From the repository root, two commands handle everything:

 ```bash
-# Install all dependencies
+# Install all dependencies (Python backend + Electron frontend)
 npm run install:all

 # Start development mode (hot reload)
 npm run dev
 ```

-`npm run install:all` installs the npm dependencies for `apps/desktop/`.
+`npm run install:all` automatically:
+- Detects Python 3.12+ on your system
+- Creates a virtual environment (`apps/backend/.venv`)
+- Installs backend runtime and test dependencies
+- Copies `.env.example` to `.env` (if not already present)
+- Installs frontend npm dependencies
+
+After install, configure your credentials in `apps/backend/.env`:
+```bash
+# Get your Claude Code OAuth token
+claude setup-token
+
+# Then edit apps/backend/.env with your token and any other provider keys
+```

+### File Encoding (Python)
+
+**Always specify `encoding="utf-8"` for text file operations** to ensure Windows compatibility.
+
+Windows Python defaults to `cp1252` encoding instead of UTF-8, causing errors with:
+- Emoji (🚀, ✅, ❌)
+- International characters (ñ, é, 中文, العربية)
+- Special symbols (™, ©, ®)
+
+**DO:**
+
+```python
+# Reading files
+with open(path, encoding="utf-8") as f:
+    content = f.read()
+
+# Writing files
+with open(path, "w", encoding="utf-8") as f:
+    f.write(content)
+
+# Path methods
+from pathlib import Path
+content = Path(file).read_text(encoding="utf-8")

+# JSON files - reading
+import json
+with open(path, encoding="utf-8") as f:
+    data = json.load(f)
+
+# JSON files - writing
+with open(path, "w", encoding="utf-8") as f:
+    json.dump(data, f, ensure_ascii=False, indent=2)
+```
+
+**DON'T:**
+
+```python
+# Wrong - platform-dependent encoding
+with open(path) as f:
+    content = f.read()
+
+# Wrong - Path methods without encoding
+content = Path(file).read_text()
+
+# Wrong - encoding on json.dump (not open!)
+json.dump(data, f, encoding="utf-8")  # ERROR
+```
+
+**Binary files - NO encoding:**
+
+```python
+with open(path, "rb") as f:  # Correct
+    data = f.read()
+```
+
+Our pre-commit hooks automatically check for missing encoding parameters. See [PR #782](https://github.com/AndyMik90/Auto-Claude/pull/782) for the comprehensive encoding fix and [guides/windows-development.md](guides/windows-development.md) for Windows-specific development guidance.

+# Test Optimization Plan
+
+## Problem Summary
+- 3 test directories timeout after 600 seconds
+- Main culprit: `test_spec_pipeline_orchestrator.py` - integration tests that run real code
+- Autouse fixture adding overhead to every test
+
+## Optimization Strategies
+
+### 1. Use Pytest Markers (Immediate Impact)
+
+Already defined in `pytest.ini`:
+```ini
+markers =
+    slow: marks tests as slow (deselect with '-m "not slow"')
+    integration: marks tests as integration tests
+```
+
+**Action:** Mark slow integration tests:
+
+```python
+@pytest.mark.slow
+@pytest.mark.integration
+async def test_run_with_auto_approve(self, tmp_path):
+    ...
+```
+
+**Run fast tests only:**
+```bash
+pytest -m "not slow" -v
+pytest -m "not integration" -v
+```
+
+**Run all tests when needed:**
+```bash
+pytest -v  # or explicitly: pytest -m "slow or integration" -v
+```
+
+### 2. Fix Autouse Fixture Overhead
+
+The `ensure_modules_not_mocked()` fixture runs before EVERY test.
+
+**Action:** Remove autouse or make it conditional:
+
+```python
+@pytest.fixture(autouse=True, scope="function")
+def ensure_modules_not_mocked():
+    """Only run for tests that need real claude_agent_sdk"""
+    # Skip for tests that explicitly mock everything
+    if os.environ.get("PYTEST_SKIP_MODULE_CLEANUP"):
+        return
+    # ... existing code ...
+```
+
+### 3. Separate Unit and Integration Tests
+
+**Directory structure:**
+```
+tests/
+├── unit/           # Fast tests (seconds)
+│   ├── test_*.py
+├── integration/    # Slow tests (minutes)
+│   ├── test_*.py
+└── e2e/           # Very slow tests (10+ minutes)
+    ├── test_*.py
+```
+
+**pytest.ini:**
+```ini
+[pytest]
+testpaths = tests/unit  # Default to fast tests
+# Override with: pytest --testpaths=integration
+```
+
+### 4. Optimize Async Tests
+
+Async tests have overhead. Use sync tests where possible:
+
+```python
+# SLOW (async overhead)
+@pytest.mark.asyncio
+async def test_something():
+    result = await some_async_function()
+    assert result
+
+# FASTER (mock the async call)
+def test_something():
+    with patch('module.some_async_function', return_value=expected):
+        result = some_function_that_calls_async()
+        assert result
+```
+
+### 5. Reduce Test Data Creation
+
+Many tests create large temporary directories. Use shared fixtures:
+
+```python
+@pytest.fixture(scope="session")
+def shared_test_data():
+    """Create test data once per session, not per test"""
+    data = create_expensive_test_data()
+    yield data
+    # cleanup runs at session end
+```
+
+### 6. Disable Coverage by Default
+
+Coverage collection adds overhead.
+
+**pytest.ini:**
+```ini
+[pytest]
+addopts = -q --tb=short  # No --cov
+# Enable coverage explicitly: pytest --cov=apps/backend
+```
+
+### 7. Increase Timeout for Integration Tests
+
+For tests that must be slow:
+
+```python
+@pytest.mark.timeout(300)  # 5 minutes for this specific test
+async def test_slow_integration():
+    ...
+```
+
+### 8. Use Test Profiles
+
+Create pytest configs for different scenarios:
+
+**pytest.unit.ini:**
+```ini
+[pytest]
+testpaths = tests
+addopts = -m "not slow and not integration" -q
+```
+
+**pytest.all.ini:**
+```ini
+[pytest]
+testpaths = tests
+addopts = -v
+timeout = 1200  # 20 minutes
+```
+
+**Usage:**
+```bash
+pytest -c pytest.unit.ini      # Fast PR checks
+pytest -c pytest.all.ini       # Full test suite
+```
+
+### 9. Mock Expensive Operations
+
+Identify what's actually slow in the tests:
+
+```python
+# SLOW - Real file I/O
+async def test_orchestrator():
+    orchestrator = SpecOrchestrator(project_dir)
+    await orchestrator.run()  # Does real file operations
+
+# FASTER - Mock the expensive parts
+async def test_orchestrator():
+    with patch('spec.pipeline.orchestrator.discover_project'):
+        with patch('spec.pipeline.orchestrator.write_files'):
+            orchestrator = SpecOrchestrator(project_dir)
+            await orchestrator.run()  # Just tests the logic
+```
+
+### 10. Run Tests in Parallel (Already Done)
+
+Use the scripts we created:
+```bash
+./scripts/run-parallel-tests.sh       # Directory-level
+./scripts/run-tests-per-file.sh       # File-level
+```
+
+## Implementation Priority
+
+1. **HIGH** - Mark slow/integration tests (5 minutes)
+   - Add `@pytest.mark.slow` to `test_spec_pipeline_orchestrator.py`
+   - Add `@pytest.mark.integration` to integration tests
+
+2. **HIGH** - Update CI to run fast tests by default (10 minutes)
+   - CI: `pytest -m "not slow"` for PR checks
+   - CI: `pytest` (full) for main branch
+
+3. **MEDIUM** - Fix autouse fixture (30 minutes)
+   - Remove autouse or make it conditional
+
+4. **MEDIUM** - Create test profiles (1 hour)
+   - Separate unit/integration configs
+
+5. **LOW** - Refactor slow tests (ongoing)
+   - Better mocking
+   - Shared fixtures
+
+## Quick Win Script
+
+Add to Makefile or scripts:
+
+```bash
+# makefile or script
+test-fast:
+    pytest -m "not slow" -v
+
+test-all:
+    pytest -v
+
+test-integration:
+    pytest -m "integration" -v
+```

+from debug import debug, debug_error
+from progress import count_subtasks
+from workspace import setup_workspace
+```
+
+### Adding Features
+
+1. Create module in appropriate folder
+2. Export API in `__init__.py`
+3. Add facade module at root if commonly imported

+# Agents Module
+
+Modular agent system for autonomous coding. This module refactors the original monolithic `agent.py` (1,446 lines) into focused, maintainable modules.
+
+## Architecture
+
+The agent system is now organized by concern:
+
+```
+auto-claude/agents/
+├── __init__.py          # Public API exports
+├── base.py              # Shared constants and imports
+├── utils.py             # Git operations and plan management
+├── memory.py            # Memory management (Graphiti + file-based)
+├── session.py           # Agent session execution
+├── planner.py           # Follow-up planner logic
+└── coder.py             # Main autonomous agent loop
+```
+
+## Modules
+
+### `base.py` (352 bytes)
+- Shared constants (`AUTO_CONTINUE_DELAY_SECONDS`, `HUMAN_INTERVENTION_FILE`)
+- Common imports and logging setup
+
+### `utils.py` (3.6 KB)
+- Git operations: `get_latest_commit()`, `get_commit_count()`
+- Plan management: `load_implementation_plan()`, `find_subtask_in_plan()`, `find_phase_for_subtask()`
+- Workspace sync: `sync_spec_to_source()`
+
+### `memory.py` (13 KB)
+- Dual-layer memory system (Graphiti primary, file-based fallback)
+- `debug_memory_system_status()` - Memory system diagnostics
+- `get_graphiti_context()` - Retrieve relevant context for subtasks
+- `save_session_memory()` - Save session insights to memory
+- `save_session_to_graphiti()` - Backwards compatibility wrapper
+
+### `session.py` (17 KB)
+- `run_agent_session()` - Execute a single agent session
+- `post_session_processing()` - Process results and update memory
+- Session logging and tool tracking
+- Recovery manager integration
+
+### `planner.py` (5.4 KB)
+- `run_followup_planner()` - Add new subtasks to completed specs
+- Follow-up planning workflow
+- Plan validation and status updates
+
+### `coder.py` (16 KB)
+- `run_autonomous_agent()` - Main autonomous agent loop
+- Planning and coding phase management
+- Linear integration
+- Recovery and stuck subtask handling
+
+## Public API
+
+The `agents` module exports a clean public API:
+
+```python
+from agents import (
+    # Main functions
+    run_autonomous_agent,
+    run_followup_planner,
+
+    # Memory functions
+    save_session_memory,
+    get_graphiti_context,
+
+    # Session management
+    run_agent_session,
+    post_session_processing,
+
+    # Utilities
+    get_latest_commit,
+    load_implementation_plan,
+    sync_spec_to_source,
+)
+```
+
+## Backwards Compatibility
+
+The original `agent.py` is now a facade that re-exports everything from the `agents` module:
+
+```python
+# Old code still works
+from agent import run_autonomous_agent, save_session_memory
+
+# New code can use modular imports
+from agents.coder import run_autonomous_agent
+from agents.memory import save_session_memory
+```
+
+All existing imports continue to work without changes.
+
+## Benefits
+
+1. **Separation of Concerns**: Each module has a clear, focused responsibility
+2. **Maintainability**: Easier to understand and modify individual components
+3. **Testability**: Modules can be tested in isolation
+4. **Backwards Compatible**: No breaking changes to existing code
+5. **Scalability**: Easy to add new agent types or features
+
+## Module Dependencies
+
+```
+coder.py
+  ├── session.py (run_agent_session, post_session_processing)
+  ├── memory.py (get_graphiti_context, debug_memory_system_status)
+  └── utils.py (git operations, plan management)
+
+session.py
+  ├── memory.py (save_session_memory)
+  └── utils.py (git operations, plan management)
+
+planner.py
+  └── session.py (run_agent_session)
+
+memory.py
+  └── base.py (constants, logging)
+```
+
+## Testing
+
+Run the verification script to test the refactoring:
+
+```bash
+python3 auto-claude/agents/test_refactoring.py
+```
+
+This verifies:
+- Module structure is correct
+- All imports work
+- Public API is accessible
+- Backwards compatibility is maintained
+
+## Migration Guide
+
+No migration needed! The refactoring maintains 100% backwards compatibility.
+
+### For new code:
+```python
+# Use focused imports for clarity
+from agents.coder import run_autonomous_agent
+from agents.memory import save_session_memory, get_graphiti_context
+from agents.session import run_agent_session
+```
+
+### For existing code:
+```python
+# Old imports continue to work
+from agent import run_autonomous_agent, save_session_memory

+
+**Check these based on context (you can infer from the diff/spec):**
+- Base Branch targeting — check based on target_branch value
+- Type of Change (bug fix, feature, docs, refactor, test) — infer from diff and spec
+- Area (Frontend, Backend, Fullstack) — infer from changed file paths
+- Feature Toggle "N/A" — if the feature appears complete and not behind a flag
+- Breaking Changes "No" — if changes appear backward compatible
+
+**Leave UNCHECKED (these require human verification you cannot perform):**
+- "I've tested my changes locally" — you have not tested anything
+- "All CI checks pass" — CI has not run yet
+- "Windows/macOS/Linux tested" — requires manual testing on each platform
+- "All existing tests pass" — CI has not run yet
+- "New features include test coverage" — unless test files are clearly visible in the diff
+- "Bug fixes include regression tests" — unless test files are clearly visible in the diff
+
+**For platform/code quality checkboxes:**
+- "Used centralized platform/ module" — leave unchecked unless you can verify from the diff
+- "No hardcoded paths" — leave unchecked unless you can verify from the diff
+- "PR is small and focused (< 400 lines)" — check only if diff stats show < 400 lines changed
+
+**For the "I've synced with develop branch" checkbox:**
+- Leave unchecked — you cannot verify the sync status

+Custom MCP Tools for Auto-Claude Agents
+========================================
+
+This module provides custom MCP tools that agents can use for reliable
+operations on auto-claude data structures. These tools replace prompt-based
+JSON manipulation with guaranteed-correct operations.
+
+Benefits:
+- 100% reliable JSON operations (no malformed output)
+- Reduced context usage (tool definitions << prompt instructions)
+- Type-safe with proper error handling
+- Each agent only sees tools relevant to their role via allowed_tools
+
+Usage:
+    from auto_claude_tools import create_auto_claude_mcp_server, get_allowed_tools
+
+    # Create the MCP server
+    mcp_server = create_auto_claude_mcp_server(spec_dir, project_dir)

+    # Get allowed tools for a specific agent type

+Codebase Analyzer
+=================
+
+Automatically detects project structure, frameworks, and services.
+Supports monorepos with multiple services.
+
+Usage:
+    # Index entire project (creates project_index.json)
+    python auto-claude/analyzer.py --index
+
+    # Analyze specific service
+    python auto-claude/analyzer.py --service backend
+
+    # Output to specific file
+    python auto-claude/analyzer.py --index --output path/to/output.json
+
+The analyzer will:
+1. Detect if this is a monorepo or single project
+2. Find all services/packages and analyze each separately
+3. Map interdependencies between services
+4. Identify infrastructure (Docker, CI/CD)
+5. Document conventions (linting, testing)
+
+This module now serves as a facade to the modular analyzer system in the analyzers/ package.
+All actual implementation is in focused submodules for better maintainability.

+=====================================================

+FACADE MODULE: This module re-exports all functionality from the

+
+The implementation has been refactored into focused modules:
+- project/command_registry.py - Command registries
+- project/models.py - Data structures
+- project/config_parser.py - Config file parsing
+- project/stack_detector.py - Stack detection
+- project/framework_detector.py - Framework detection
+- project/structure_analyzer.py - Project structure analysis
+- project/analyzer.py - Main orchestration
+
+This file maintains the original API so existing imports continue to work.
+
+This system:
+1. Detects languages, frameworks, databases, and infrastructure
+2. Parses package.json scripts, Makefile targets, pyproject.toml scripts
+3. Builds a tailored security profile for the specific project
+4. Caches the profile for subsequent runs
+5. Can re-analyze when project structure changes
+
+The goal: Allow an AI developer to run any command that's legitimately
+needed for the detected tech stack, while blocking dangerous operations.
