Quick Start

Start here: End-to-End Workflow

Fastest Bootstrap

# Brand new project directory
mkdir my-verse-project
cd my-verse-project

# 1) Create and activate virtualenv
python3 -m venv .venv
source .venv/bin/activate

# 2) Install SDK
pip install sanatan-verse-sdk

# 3) Scaffold project
verse-init --collection hanuman-chalisa

# 4) Initialize git repo (after scaffolding to avoid non-empty prompt)
git init

See full command docs: verse-init

New Project Setup (Recommended)

# 1. Install
pip install sanatan-verse-sdk

# 2. Create project with collection templates
verse-init --project-name my-verse-project --collection hanuman-chalisa
cd my-verse-project

# 3. Configure API keys
cp .env.example .env
# Edit .env and add your API keys from:
# - OpenAI: https://platform.openai.com/api-keys
# - ElevenLabs: https://elevenlabs.io/app/settings/api-keys

# 4. Add canonical Devanagari text
# Edit data/verses/hanuman-chalisa.yaml with actual verse text

# 5. Validate setup
verse-validate

# 6. Generate multimedia content
verse-generate --collection hanuman-chalisa --verse 1

What you get: Verse file, AI-generated image, audio (full + slow speed), and search embeddings!

Existing Project

# Validate and fix structure
verse-validate --fix

# Generate content
verse-generate --collection hanuman-chalisa --verse 15

# Check status
verse-status --collection hanuman-chalisa

Advanced Usage

# Multiple collections at once
verse-init --collection hanuman-chalisa --collection sundar-kaand

# Custom number of sample verses
verse-init --collection my-collection --num-verses 10

# Generate specific components only
verse-generate --collection sundar-kaand --verse 3 --image
verse-generate --collection sundar-kaand --verse 3 --audio

# Skip embeddings update (faster)
verse-generate --collection hanuman-chalisa --verse 15 --no-update-embeddings

What Gets Generated

Each verse generation creates:

• 🎨 Image: images/{collection}/{theme}/verse-01.png (DALL-E 3)
• 🎵 Audio (full): audio/{collection}/verse-01-full.mp3 (ElevenLabs)
• 🎵 Audio (slow): audio/{collection}/verse-01-slow.mp3 (0.75x speed)
• 🔍 Embeddings: data/embeddings/collections/{collection}.json + data/embeddings/collections/index.json (for semantic search)

Text Source: Canonical Devanagari text from data/verses/{collection}.yaml (Local Verses Guide)

Migration Note: Legacy combined embeddings (data/embeddings.json) are no longer written by default. Use verse-embeddings --legacy-output if you still need the combined file.

Puranic Context Generation

Enrich verse pages with grounded story references from indexed sacred texts. Two-stage workflow:

Stage 1 — Index a Source Text

verse-index-sources --file data/sources/ananda-ramayana.txt

This command:

1. Splits the source text into ~4000-char chunks
2. Parses each chunk into discrete named episodes (keywords, type, summary in English + Hindi)
3. Generates embeddings for each episode
4. Writes outputs:
   • data/puranic-index/{key}.yml — human-readable episode index with _meta section
   • data/embeddings/puranic/{key}.json — embedding vectors for RAG retrieval
   • data/puranic-references.yml — registry of indexed sources

Only needs to run once per source, or when the source file changes.

# Use Bedrock Cohere for better Sanskrit/Hindi accuracy
verse-index-sources --file data/sources/shiv-puran.txt --provider bedrock-cohere

# If Bedrock input exceeds limits, use truncation policy
verse-embeddings --provider bedrock-cohere --truncate-policy chunk

# Larger chunk size for dense Puranic prose
verse-index-sources --file data/sources/valmiki-ramayana.pdf --chunk-size 6000

Stage 2 — Generate Puranic Context per Verse

verse-puranic-context --collection hanuman-chalisa --all

For each verse this command:

1. Embeds the verse text using the same provider as the indexed source
2. Runs cosine similarity search across all indexed sources to find the most relevant episodes
3. Filters to episodes involving the collection's subject (configured in _data/collections.yml)
4. Passes top episodes + verse text to GPT-4o with citation constraints
5. Post-validates each entry: drops entries where the subject is not an active participant
6. Writes puranic_context: block into the verse's .md frontmatter

# Skip verses that already have context (default)
verse-puranic-context --collection hanuman-chalisa --all

# Regenerate all existing entries
verse-puranic-context --collection hanuman-chalisa --all --regenerate

# Single verse
verse-puranic-context --collection hanuman-chalisa --verse chaupai-06

Collection Subject Configuration

The subject filter is resolved via a two-level hierarchy — no CLI flag needed:

Option A — Project-level default (single-subject projects): set once in _data/verse-config.yml, applies to all collections:

# _data/verse-config.yml
defaults:
  subject: Hanuman
  subject_type: deity

Option B — Collection-level override: set per collection in _data/collections.yml (takes priority over project default):

# _data/collections.yml
hanuman-chalisa:
  subject: Hanuman      # overrides or supplements project default
  subject_type: deity

krishna-bhajans:
  subject: Krishna      # different subject for this collection
  subject_type: deity

Resolution order: collection-level → project default → error if neither is set and indexed sources exist.

Multiple Sources

Multiple indexed sources are automatically combined in RAG retrieval:

_data/verse-config.yml         ← set defaults.subject here

data/sources/
  shiv-puran-part1.txt
  ananda-ramayana.txt        ← add new sources here

data/puranic-index/
  shiv-puran-part1.yml       ← auto-generated episode index
  ananda-ramayana.yml

data/embeddings/
  puranic/
    shiv-puran-part1.json      ← auto-generated embedding vectors
    ananda-ramayana.json

See verse-index-sources and verse-puranic-context for full documentation.

Migration Note: Puranic embeddings now live under data/embeddings/puranic/. If you have legacy files in data/embeddings/{source}.json, move them or re-run verse-index-sources to regenerate.
