How AI skill extraction works

From book to agent skill in three steps

skillcrawl extracts. skill.broker distributes. Your agent executes.

Extract

Feed books, papers, and manuals into skillcrawl. It returns structured SKILL.md files with evidence-grounded steps, conditions, and evaluation criteria.

→

List

Post your extracted skills on skill.broker. Set a price, attach provenance metadata, and reach agent builders who need domain expertise.

→

Execute

Buyers drop SKILL.md files into their agent's skill library. The agent reads and executes the skill without human restructuring.

The SKILL.md format

Structured skill definitions, agent-native by design

Every skill on the marketplace is a SKILL.md file: YAML frontmatter plus imperative markdown. Not a summary. Not a prompt. A structured skill definition your AI agent can execute.

Imperative steps with rationale and pitfall guards
Evaluation criteria the agent uses to verify success
Evidence pointers traced to source material
Confidence scores so your agent knows what to trust
Provenance metadata for marketplace verification

# Tactical Empathy: Labeling

## When to Use
- The other party is visibly frustrated
- A negotiation has stalled
- You need rapport before a request

## Steps
1. Observe the emotion without reacting
2. Label with "It seems like..."
3. Wait silently after the label
4. Follow with a calibrated question

## Evaluation Criteria
- They elaborate after your label
- Defensive tone decreases

## Evidence
"Labeling is a way of validating
 someone's emotion by acknowledging
 it." (Ch 3, p. 52)
