axio-tui-rag 0.3.3

RAG plugin for Axio TUI

axio-tui-rag

RAG (Retrieval-Augmented Generation) plugin for axio-tui.

Index your local files into a vector store and let the agent search them semantically. Point the agent at a codebase, documentation, or notes — it retrieves relevant chunks without reading every file.

Features

• File indexing — chunk and embed files into a LanceDB vector store
• Semantic search — retrieve the most relevant chunks for a query using embedding similarity
• Incremental updates — re-indexing a file replaces its old chunks; unchanged files are skipped
• Two axio tools — index_files and semantic_search registered via entry points

Installation

pip install axio-tui-rag

Or install as part of the TUI bundle:

pip install "axio-tui[rag]"

Usage

Via axio-tui (recommended)

Launch the TUI with RAG enabled — the agent gains two new tools automatically:

pip install "axio-tui[rag,openai]"
axio

Then ask the agent:

• "Index all Python files in ./src"
• "Search for how authentication is implemented"

Standalone

from axio import Agent
from axio.context import MemoryContextStore
from axio_transport_openai import OpenAITransport
from axio_tui_rag import IndexFiles, SemanticSearch
from axio.tool import Tool

tools = [
    Tool(name="index_files",    description=IndexFiles.__doc__ or "",    handler=IndexFiles),
    Tool(name="semantic_search", description=SemanticSearch.__doc__ or "", handler=SemanticSearch),
]

agent = Agent(
    system="You are a code assistant. Index files before searching.",
    tools=tools,
    transport=OpenAITransport(api_key="sk-...", model="gpt-4o"),
)

Tools

index_files

Index one or more files into the vector store for later semantic search. Files are chunked and embedded. Re-indexing a file replaces its old chunks.

Parameters:

• paths: list[str] — file paths to index (relative to cwd)

semantic_search

Search the vector store for chunks semantically similar to a query. Returns ranked excerpts with file paths and line numbers.

Parameters:

• query: str — natural-language search query
• limit: int (default: 5) — number of results to return

Plugin registration

[project.entry-points."axio.tools"]
index_files     = "axio_tui_rag:IndexFiles"
semantic_search = "axio_tui_rag:SemanticSearch"
