Convert books to executable SKILL.md files

Books and papers encode task-performance knowledge as prose. Your AI agents need structured skill definitions with steps, conditions, and evaluation criteria. Skillcrawl automates the extraction.

Input
Long-form content
PDFs, EPUBs. Books, papers, manuals. Narrative prose optimized for human reading.
Process
Extraction pipeline
Parse. Mine candidates. Synthesize with evidence grounding. Deduplicate. Score confidence.
Output
SKILL.md files
LLM-consumable skill definitions. Imperative steps, guard rails, evaluation criteria, source provenance.

Structured skill definitions agents execute

Each extracted skill is a standalone SKILL.md file with YAML frontmatter and imperative markdown. AI agents load and execute them directly. Humans can audit and edit them.

Skill body
## When to Use
The other party is visibly frustrated
or defensive. A negotiation has stalled.

## Steps
1. Observe the emotion without reacting
2. Label with "It seems like..."
   Pitfall: Do not use "I understand"
3. Wait silently after the label
4. Follow with a calibrated question

## Evaluation Criteria
Success: other party elaborates
Failure: you interrupt the silence

How it works

Submit a document to skillcrawl.sh via the CLI or REST API. The extraction pipeline parses, mines candidates, synthesizes evidence-grounded skills, deduplicates, and scores confidence. You get back a set of SKILL.md files your agents can execute immediately.

Credit-based pricing scales with document length and extraction granularity. Every job includes an extraction report with per-skill confidence scores and provenance metadata.
