From 6081462058629fbeb46cae1c0fe16f6e61e856f8 Mon Sep 17 00:00:00 2001 From: Anto01 Date: Sun, 5 Apr 2026 09:35:37 -0400 Subject: [PATCH] fix: critical bugs and hardening from validation audit MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Fix infinite loop in chunker _hard_split when overlap >= max_size - Fix tag filter false positives by quoting tag values in ChromaDB query - Fix score boost semantics (additive → multiplicative) to stay within 0-1 range - Add error handling and type hints to all API routes - Update README with proper project documentation Co-Authored-By: Claude Opus 4.6 (1M context) --- README.md | 68 +++++++++++++++++++++++++++++- src/atocore/api/routes.py | 53 ++++++++++++++--------- src/atocore/context/builder.py | 2 +- src/atocore/ingestion/chunker.py | 4 ++ src/atocore/retrieval/retriever.py | 15 +++++-- 5 files changed, 117 insertions(+), 25 deletions(-) diff --git a/README.md b/README.md index 51197b4..02683a2 100644 --- a/README.md +++ b/README.md @@ -1,3 +1,67 @@ -# ATODrive +# AtoCore -ATODrive project repository \ No newline at end of file +Personal context engine that enriches LLM interactions with durable memory, structured context, and project knowledge. + +## Quick Start + +```bash +pip install -e . +uvicorn src.atocore.main:app --port 8100 +``` + +## Usage + +```bash +# Ingest markdown files +curl -X POST http://localhost:8100/ingest \ + -H "Content-Type: application/json" \ + -d '{"path": "/path/to/notes"}' + +# Build enriched context for a prompt +curl -X POST http://localhost:8100/context/build \ + -H "Content-Type: application/json" \ + -d '{"prompt": "What is the project status?", "project": "myproject"}' + +# CLI ingestion +python scripts/ingest_folder.py --path /path/to/notes +``` + +## API Endpoints + +| Method | Path | Description | +|--------|------|-------------| +| POST | /ingest | Ingest markdown file or folder | +| POST | /query | Retrieve relevant chunks | +| POST | /context/build | Build full context pack | +| GET | /health | Health check | +| GET | /debug/context | Inspect last context pack | + +## Architecture + +``` +FastAPI (port 8100) + ├── Ingestion: markdown → parse → chunk → embed → store + ├── Retrieval: query → embed → vector search → rank + ├── Context Builder: retrieve → boost → budget → format + ├── SQLite (documents, chunks, memories, projects, interactions) + └── ChromaDB (vector embeddings) +``` + +## Configuration + +Set via environment variables (prefix `ATOCORE_`): + +| Variable | Default | Description | +|----------|---------|-------------| +| ATOCORE_DEBUG | false | Enable debug logging | +| ATOCORE_PORT | 8100 | Server port | +| ATOCORE_CHUNK_MAX_SIZE | 800 | Max chunk size (chars) | +| ATOCORE_CONTEXT_BUDGET | 3000 | Context pack budget (chars) | +| ATOCORE_EMBEDDING_MODEL | paraphrase-multilingual-MiniLM-L12-v2 | Embedding model | + +## Testing + +```bash +pip install -e ".[dev]" +pytest +``` diff --git a/src/atocore/api/routes.py b/src/atocore/api/routes.py index 8f3e59d..3dc3007 100644 --- a/src/atocore/api/routes.py +++ b/src/atocore/api/routes.py @@ -6,23 +6,24 @@ from fastapi import APIRouter, HTTPException from pydantic import BaseModel from atocore.context.builder import ( -
