All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

0.1.3 - 2026-02-05

Added

  • CLI Embedding Configuration: New flags for choosing embedding providers

    • --embedder: Choose provider (mock, hf, openai, cohere, voyage)
    • --model: Specify model name for the embedder
    • --dimension: Set embedding dimension (required for API providers)
    • Examples: indra --embedder hf create "thought", indra --embedder openai --model text-embedding-3-small create "thought"

  • Documentation: CLI_EMBEDDINGS.md with complete CLI embedding guide

    • Quick start examples for all providers
    • Environment variable requirements
    • Consistency guidelines
    • Troubleshooting tips

Changed

  • Updated open_db() function to accept embedder configuration parameters
  • All CLI commands now support embedder selection

0.1.2 - 2026-02-05

Added

  • HFEmbedder: Local transformer model support via Candle

    • Downloads models from HuggingFace Hub with caching
    • Supports sentence-transformers and BERT-compatible models
    • Respects HF_HOME and HF_TOKEN environment variables
    • Mean pooling and normalization for quality embeddings
    • Examples: all-MiniLM-L6-v2, all-mpnet-base-v2, bge-small-en-v1.5

  • ApiEmbedder: External embedding API support

    • OpenAI (text-embedding-3-small, text-embedding-3-large)
    • Cohere (embed-english-v3.0, embed-multilingual-v3.0)
    • Voyage AI (voyage-3, voyage-3-lite, voyage-code-3)
