-### 🚀 **Project Initialization and Setup**
-
-- [x] Create a GitHub repository named `forq-cli`.
-- [x] Clone repository locally and initialize with `npm init -y`.
-- [x] Set up `.gitignore` to exclude `node_modules`, `.env`, logs, and build artifacts.
-- [x] Install TypeScript and initialize configuration (`tsconfig.json`).
-- [x] Configure ESLint (`.eslintrc.json`) and Prettier (`.prettierrc`) for code formatting and linting.
-- [x] Add scripts to `package.json` for build, lint, test, and run.
-- [x] Set up basic folder structure (`src/`, `tests/`, `bin/`, `config/`).
-
----
-
-### 📦 **CLI Interface and Command Parsing**
-
-- [x] Install `commander` and set up basic CLI entry point (`bin/forq.ts`).
-- [x] Implement main command to invoke interactive REPL (`forq repl`).
-- [x] Implement help command (`forq --help`) that displays available commands.
-- [x] Ensure executable permissions (`chmod +x bin/forq.ts`) and link via npm scripts.
-- [x] Verify basic CLI execution (`./bin/forq.ts repl`) runs without errors.
-
----
-
-### 🎛️ **Interactive REPL Implementation**
-
-- [x] Install and configure `readline` or `enquirer` for user input.
-- [x] Implement interactive REPL loop: prompt user, process input, return response.
-- [x] Handle basic REPL commands (`/help`, `/clear`, `/exit`) with meaningful output.
-- [x] Maintain command history navigation using arrow keys.
-- [x] Add REPL prompt customizations (colors, context indicators).
-
----
-
-### 🧠 **System Prompt and User Prompt Management**
-
-- [x] Create and store the `systemPrompt` text in a dedicated config file (`config/systemPrompt.ts`).
-- [x] Load and inject `systemPrompt` at initialization of AI context.
-- [x] Accept user input as a structured `userPrompt` for sending to AI API.
-- [x] Ensure prompts follow formatting standards (Markdown/structured JSON).
-- [x] Log user and AI prompts in timestamped conversation history (`logs/conversation.log`).
-
----
-
-### ⚙️ **AI Integration and Semantic Querying**
-
-- [x] Install and configure the Anthropic SDK (or compatible alternative API client).
-- [x] Set up `.env` file to securely store API keys and environment variables.
-- [x] Implement function to query AI (`queryAI(messages: Message[])`) with streaming output.
-- [x] Verify basic API connectivity by sending a simple test message and receiving response.
-
----
-
-### 📂 **Tool System: Core Implementation**
-
-- [x] Define `Tool` interface with structured inputs, outputs, and execution logic.
-- [x] Implement dynamic tool loading mechanism (e.g., scan `tools/` directory at startup).
-- [x] Provide a method (`executeTool`) to invoke tools based on AI-generated tool calls.
-- [x] Verify basic tool invocation through mock calls in REPL.
-
----
-
-### 🛠️ **Individual Tools Implementation**
-
-#### **File System Tools**
-
-- [x] Implement `listDir` tool: List files/directories at given path.
-- [x] Implement `readFile` tool: Return file content securely.
-- [x] Implement `editFile` tool: Overwrite file content after diff verification.
-- [x] Implement `deleteFile` tool: Delete specified file safely (with confirmation prompt).
-- [x] Implement `createFile` tool: Create new files with content, checking for existing files.
-
-#### **Search Tools**
-
-- [x] Implement `fileSearch` tool: Fuzzy match filenames across directories.
-- [x] Implement `ripgrepSearch` tool: Regex content search via `ripgrep`.
-
-#### **Semantic Tools**
-
-- [x] Set up basic semantic embedding mechanism (stub function for embedding text).
-- [x] Implement `semanticSearch` tool: Return semantically relevant code snippets based on query.
-- [x] Implement `readSemanticSearchFiles` tool: Retrieve top semantic matches with full file content.
-
-#### **Terminal Command Tool (Bash Integration)**
-
-- [x] Implement `bash` tool: Execute commands in a secure, persistent shell session.
-- [x] Ensure commands have strict permission verification (banned commands, safe execution environment).
-- [x] Capture and handle stdout/stderr, enforce timeout mechanisms (default 2 min).
-- [x] Persist environment variables and working directories between bash calls.
-
----
-
-### 🛡️ **Security & Permission System**
-
-- [x] Implement per-session permission store (in-memory).
-- [x] Prompt user clearly for tool permissions on first use (e.g., file access, shell command execution).
-- [x] Persist granted permissions in a session configuration (`config/session-permissions.json`).
-- [x] Enforce strict checking of permissions before any sensitive tool action.
-
----
-
-### 📚 **Context Management**
-
-- [x] Implement automatic loading of project-specific instructions from `FORQ.md`.
-- [x] Collect git context (current branch, modified files, recent commits) using bash tool.
-- [x] Provide summarized directory structure to AI on session start.
-- [x] Compact conversation history periodically (`/compact` command implementation).
-
----
-
-### 📑 **Configuration Management**
-
-- [x] Implement global config storage (`~/.forqrc.json`) to persist user preferences and API keys.
-- [x] Implement project-specific config (`.forqrc.json`) for allowed tools, commands, and local overrides.
-- [x] Provide CLI command (`forq config`) to view and edit configurations.
-
----
-
-### 📊 **Analytics & Error Handling**
-
-- [x] Implement basic analytics logging (session duration, commands used).
-- [x] Implement local error logging (`logs/error.log`) capturing stack traces.
-
----
-
 ### 🔍 **Logging & Auditability**
 
 - [x] Ensure each AI action (tool execution, API call) is logged in structured logs (`logs/actions.log`).
@@ -148,3 +25,66 @@
 - [x] Add detailed documentation (`docs/`) for each CLI command, prompt conventions, and available tools.
 - [x] Provide example workflows (e.g., bugfixes, feature implementations) in the documentation.
 - [x] Implement `forq help <command>` providing detailed contextual help.
