-# The AI Software Foundry
+# code2test
 
-An autonomous software engineering platform that continuously analyzes, tests, and improves your codebase. It acts as an integrated AI team member, ensuring code quality and reliability across the entire development lifecycle.
+## **Core Philosophy: "Pragmatic Intelligence with Zero Waste"**
 
-## Features
+This architecture combines:
+- **Specification-driven generation** (tests what SHOULD happen)
+- **Code-aware validation** (understands what DOES happen)
+- **Incremental healing** (fixes only what's broken)
+- **Tool orchestration** (leverages existing solutions)
+- **Fact-based generation** (zero hallucination)
 
--   **Continuous Integration & Learning**: Hooks directly into your Git repository, learning from every commit and keeping its understanding of your code perpetually up-to-date.
--   **Scales to Any Size**: Built on a Retrieval-Augmented Generation (RAG) and micro-agent architecture, it handles million-line codebases with ease.
--   **Intelligent Impact Analysis**: When a change is made, it precisely identifies the affected parts of the system and intelligently scopes its work, saving massive amounts of time and compute.
--   **Autonomous Generate-Verify-Heal Loop**: It doesn't just write code; it compiles it, runs it in a secure sandbox, analyzes failures, and autonomously fixes bugs in either the tests or the source code itself.
--   **Multi-Agent Specialization**: Employs a team of specialized AI agents for testing, debugging, refactoring, and documentation to ensure expert-level quality at every step.
--   **Seamless SDLC Integration**: Interacts with developers through GitHub pull requests, Slack notifications, and a powerful CLI.

-## How It Works: The Foundry Lifecycle

-1.  **Continuous Learning**: The **Indexing Service** listens for `git push` events. On every commit, it performs an *incremental* analysis, updating a vector-based **Knowledge Graph** that serves as the Foundry's central memory.
-2.  **Task Initiation**: A developer initiates a task, for example by commenting `@AIFoundry test this PR` on a pull request.
-3.  **Intelligent Orchestration**: The **Orchestration Service** receives the request. It first performs an **Impact Analysis** by querying the Knowledge Graph to determine exactly what needs to be tested.
-4.  **Specialized Agent Execution**: The Orchestrator dispatches sub-tasks to the appropriate agent in the **Agent Core**. The **Testing Agent** uses RAG to retrieve necessary context and generate test code.
-5.  **Sandboxed Verification**: The generated code is sent to the **Execution Sandbox**, a secure, scalable environment where it is compiled and run.
-6.  **The Heal Loop**: If verification fails, a "debug" task is created. The **Debugging Agent** analyzes the failure, queries the Knowledge Graph for context, and generates a code patch. The patched code is then sent back for re-verification. This loop continues until the suite passes.
-7.  **Reporting**: The final result—a passed test suite, a code review with suggestions, or an updated documentation file—is reported back to the developer through the original interface (e.g., a comment on the PR).
