description	It reads from your local zettelkasten notes, find a random idea, and find references by links or tags, then expand the idea with the references.

Zettel Brainstormer 🧠

This skill formalizes the process of taking a rough idea or draft and enriching it with deep research, diverse perspectives, and structured brainstorming.

The configuration file is config/models.json, which can be edited manually or using the setup.py script.

New 3-Stage Workflow

This skill now supports a 3-stage pipeline to balance cost and quality:

1. Find References (with find_links.py)

• Run scripts/find_links.py to identify relevant existing notes.
  • Wikilinked documents (follows [[wikilinks]] N levels deep, up to M total docs)
  • Tag-similar documents (finds notes with overlapping tags)
  • Native Obsidian Integration: Uses obsidian-cli for high-performance indexing and discovery if available.
  • Semantic Discovery (Optional): Can leverage the zettel-link skill for finding "hidden" conceptual connections that don't share explicit tags or links.
• Output: A JSON list of absolute file paths to relevant notes.

2. Subagent: Preprocess contents (with preprocess_model)

• The agent iterates through the list of files found in Stage 1.
• For each file:
  • Read the file content.
  • Apply templates/preprocess.md using the preprocess_model, pass the seed note keypoints and file content as context.
  • Extract: Relevance score, Summary, Key Points, and Quotes.
  • Output: A structured markdown summary of the note.

3. Draft & Humanize (with pro_model)

• Gather all preprocessed markdown outputs from Stage 2.
• Apply templates/draft.md using the pro_model.
• Synthesize points, add proper Obsidian properties, tags, and links.
• Uses the obsidian skill if available to match style.

Files & Scripts

This skill includes the following resources under the skill folder:

• scripts/find_links.py -- finds relevant note paths (linked + tag similar)
• scripts/draft_prompt.py -- (Deprecated) generate prompt for agent
• scripts/obsidian_utils.py -- shared utilities for wikilink extraction
• templates/preprocess.md -- Instructions for subagent to extract info from single note
• templates/draft.md -- Instructions for final draft generation
• config/models.example.json -- example configuration file

Configuration & Setup

First Run Setup: Before using this skill, you must run the setup script to configure models and directories.

python scripts/setup.py

This will create config/models.json with your preferences. You can press ENTER to accept defaults.

Configuration Fields:

• pro_model: The model used for drafting (defaults to agent's current model)
• preprocess_model: Cheap model for extraction (defaults to agent's current model)
• zettel_dir: Path to your Zettelkasten notes
• output_dir: Path where drafts should be saved
• search_skill: Which search skill to use for web/X research (web_search, brave_search, or none)
• link_depth: How many levels deep to follow [[wikilinks]] (N levels, default: 2)
• max_links: Maximum total linked notes to include (M links, default: 10)
• discovery_mode: Options are standard (default), cli (uses obsidian-cli), or semantic (uses zettel-link).

Usage

• Trigger when user asks: "brainstorm X", "expand this draft", "research and add notes to ".
• Example workflow (pseudo):
  1. Pick a seed note.
  2. Find Links: python scripts/find_links.py --input <seed_note> --output /tmp/paths.json
  3. Preprocess Subagent Loop:
     • Load /tmp/paths.json.
     • For each path, read content.
     • Prompt preprocess_model with templates/preprocess.md + content.
     • Store result.
  4. Final Draft:
     • Concatenate seed note + all preprocess results.
     • Prompt pro_model with templates/draft.md + concatenated context.
  5. Save result to note.

Notes for maintainers

• Keep preprocess outputs small (200-600 tokens) to save cost.
• Ensure all external links are included in the References section with full titles and URLs.
• When appending, always include a timestamp and short provenance line.
