-# Project: Codebase Traversal and Gemini AI Integration
+# Codebase Prompting → Repository Intelligence
 
-This repository contains two Python scripts: `base_print.py` and `base_print_ai.py`.
+This repository is being evolved from file-dump prompting scripts into a deterministic repository-intelligence engine for governed software development.
 
-## `base_print.py`
+## v1 capabilities
 
-This script traverses a given directory, collects all text files (with certain extensions), and writes their content to an output file. It handles large files by skipping them and provides a continuation mechanism using a unique key.
+- repository file inventory with SHA-256 content identity;
+- Python top-level symbol graph;
+- Python import dependency graph;
+- relative JS/TS import dependency graph;
+- reverse dependency change-impact analysis;
+- deterministic graph and impact digests;
+- CLI suitable for CI and OpenHands/agent consumption.
 
-### Features
-- Traverses directories, ignoring specified folders and files.
-- Collects text file contents up to specified limits.
-- Generates a continuation key to resume processing.
-- Outputs a directory tree with indicators for processed and skipped files.
+No LLM is required for v1 graph construction. This keeps repository structure and change-impact evidence reproducible.
 
-### Usage
-1. **Run the Script**:
-    ```bash
-    python base_print.py [directory] [continue_key]
-    ```
-    - `directory`: The directory to search (default is the current directory).
-    - `continue_key`: The key to continue from where it left off (optional).
+## CLI
 
-2. **Output**:
-    - Generates `codebase_n.txt` with the collected contents and directory tree.
-    - Prints the continuation key if the line limit is reached.
+```bash
+repo-intel graph /path/to/repo --out repository-graph.json
+repo-intel impact repository-graph.json src/example.py --depth 3 --out change-impact.json
+```
 
-## `base_print_ai.py`
+## Legacy scripts
 
-This script extends the functionality of `base_print.py` by integrating with the Google Gemini API. It uses the API to determine relevant files based on a user prompt and processes those files.
-
-### Features
-- Integrates with Google Gemini API for intelligent file selection.
-- Processes files based on the relevance determined by the API.
-- Outputs a directory tree with indicators for processed and skipped files.
-
-### Usage
-1. **Set Up API Key**:
-    - Ensure you have set the `API_KEY` environment variable with your Google Gemini API key.
-
-2. **Run the Script**:
-    ```bash
-    python base_print_ai.py [directory] [continue_key]
-    ```
-    - `directory`: The directory to search (default is the current directory).
-    - `continue_key`: The key to continue from where it left off (optional).
-
-3. **Output**:
-    - Generates `prompt_n.txt` with the collected contents and directory tree.
-    - Prompts the user for an input prompt to guide the file selection process.
+`base_print.py` and `base_print_ai_model.py` are preserved as historical utilities. They are not the architectural foundation of the new repository-intelligence layer.
