Invisible Threads Skill

Discovers non-obvious thematic connections ("invisible threads") across a corpus of essays, articles, or transcripts.

Adapted from invisible-threads.

When to Use

• •Editing an anthology and want to find thematic connections
• •Analyzing a body of work for recurring ideas
• •Finding quotes that support a theme across multiple sources
• •Writing editorial commentary that weaves sources together

Quick Start

# 1. Prepare your corpus as markdown files in a source directory

# 2. Chunk the corpus into a database
python chunk_corpus.py --source /path/to/markdown/files --output corpus.db

# 3. Extract insights using Gemini
python extract_insights.py --db corpus.db --backend gemini

# 4. Find threads
python find_threads.py --input data/insights_*.json

# 5. Review threads_*.json for editorial use

Adapting for Your Project

The key file to modify is the extraction prompt in extract_insights.py.

Default Prompt Categories

The default is set up for Catholic agrarian content (Cross & Plough):

• •industrialism, land, family, property, craft, liturgy
• •organic-farming, distributism, eugenics, totalitarianism
• •natural-law, peasantry, economics, spirituality

For Other Projects

Change the EXTRACTION_PROMPT in extract_insights.py:

1. •Context section: Describe what the corpus is
2. •Examples section: Give 3 examples of genuine insights from this domain
3. •Categories: List 10-15 thematic categories relevant to your content

See references/prompt-templates.md for examples.
