What this skill tells the agent
indexion segment
Split text into contextual segments using divergence-based, TF-IDF, or punctuation strategies.
When to Use
- User needs to chunk text for RAG or embedding pipelines
- User wants to split a document into meaningful sections
- User asks to segment text for processing
- Preparing text for similarity analysis at sub-document level
Usage
# Default window divergence strategy
indexion segment <input-file> <output-dir>
# TF-IDF based segmentation
indexion segment --strategy=tfidf <input-file> <output-dir>
# Punctuation-based segmentation
indexion segment --strategy=punctuation <input-file> <output-dir>
# Custom segment sizes
indexion segment --min-size=200 --max-size=3000 --target-size=800 document.txt output/
# Custom divergence threshold
indexion segment --threshold=0.5 document.txt output/
# Adaptive threshold mode (default)
indexion segment --adaptive document.txt output/
# Hybrid NCD+TF-IDF mode
indexion segment --hybrid --ncd-weight=0.6 --tfidf-weight=0.4 document.txt output/
# Custom window size
indexion segment --window-size=5 document.txt output/
# Custom output prefix
indexion segment --prefix=chunk document.txt output/Options
| Option | Default | Description |
|---|---|---|
--strategy=NAME | window | Strategy: window, tfidf, punctuation |
--min-size=INT | 100 | Minimum segment characters |
--max-size=INT | 2000 | Maximum segment characters |
--target-size=INT | 500 | Target segment characters |
--threshold=FLOAT | 0.42 | Divergence threshold |
--window-size=INT | 3 | Window size |
--adaptive | true | Adaptive threshold mode |
--hybrid | false | NCD+TF-IDF hybrid mode |
--ncd-weight=FLOAT | 0.5 | NCD weight in hybrid mode |
--tfidf-weight=FLOAT | 0.5 | TF-IDF weight in hybrid mode |
--prefix=NAME | segment | Output file prefix |
Strategies
| Strategy | Description |
|---|---|
window (default) | Sliding window divergence detection |
tfidf | TF-IDF based topic change detection |
punctuation | Punctuation/sentence boundary based |
Workflow
- Run
indexion segment <input-file> <output-dir>to split text with defaults - Adjust
--thresholdand--target-sizeto tune segmentation granularity - Use
--hybridmode for better accuracy on mixed-content documents
