Install and run

Setup complexity: low.

clawhub skill install s179srg0a58h1v79wy2w7g9ymh83jxhd:pbe-extractor

Setup complexity is LOW. This package is likely designed for quick installation with minimal external side-effects.
Final validation: Expose the agent to a mock request payload inside a sandbox and trace the network egress before allowing access to real customer data.

Contract: missing

# PBE Extractor

## Agent Identity

**Role**: Help users extract invariant principles from content
**Understands**: Users need structured, repeatable methodology they can verify
**Approach**: Apply Bootstrap → Learn → Enforce with explicit confidence levels
**Boundaries**: Identify patterns, never determine absolute truth
**Tone**: Precise, methodical, honest about uncertainty
**Opening Pattern**: "You have content that might be more than it appears — let's find the principles that would survive any rephrasing."

**Data handling**: This skill operates within your agent's trust boundary. All content analysis
uses your agent's configured model — no external APIs or third-party services are called.
If your agent uses a cloud-hosted LLM (Claude, GPT, etc.), data is processed by that service
as part of normal agent operation. This skill does not write files to disk.

## When to Use

Activate this skill when the user asks to:
- "Extract the principles from this"
- "What are the core ideas here?"
- "Compress this while keeping the meaning"
- "Find the patterns in this content"
- "Distill this document"

## Important Limitations

- Extracts PATTERNS, not truth — principles need validation (N≥2)
- Cannot verify extracted principles are correct
- High compression may lose nuance — always review
- Works best with 200+ words of content
- Principles start at N=1 (single source) — use comparison skill to validate

---

## Input Requirements

User provides:
- Text content (documentation, methodology, philosophy, code comments)
- (Optional) Domain context for better semantic markers
- (Optional) Target compression level

Minimum: 50 words
Recommended: 200-3000 words
Maximum: Context window limits apply

---

## Methodology

This skill uses **Principle-Based Distillation (PBD)** to extract invariant principles from content.

**Core Insight**: Compression is comprehension. The ability to compress without loss demonstrates true understanding.

### What is an Invariant Principle?

A principle is invariant when it:
1. Survives rephrasing (same idea, different words)
2. Can regenerate the original meaning
3. Separates essential from accidental complexity

### The Extraction Process

**Bootstrap**: Read source material without judgment
**Learn**: Identify patterns, test for invariance
**Enforce**: Validate through rephrasing test

### The Rephrasing Test

A principle passes when:
- It can be expressed with completely different words
- The meaning remains identical
- No information is lost

**Pass**: "Small files reduce cognitive load" ≈ "Shorter code is easier to understa

## Description:

Extract invariant principles from text and identify ideas that survive rephrasing.

This skill is ready for commercial/non-commercial use.

## Publisher:

[leegitw](https://clawhub.ai/user/leegitw)

### License/Terms of Use:

MIT-0

## Use Case:

External users and developers use this skill to distill documents, methodology notes, code comments, or other text into structured principle observations with confidence levels and source evidence. It is useful when readers need concise, reviewable patterns rather than claims of verified truth.

### Deployment Geography for Use:

Global

## Known Risks and Mitigations:

Risk: Sensitive pasted content may be processed by the user's configured model provider.

Mitigation: Avoid submitting secrets or regulated data unless the configured agent and model provider are approved for that content.

Risk: Extracted principles are pattern observations, not verified truths.

Mitigation: Review the extracted principles and validate them against additional sources before relying on them.

Risk: Documentation mentions review artifacts in a way that may confuse users about whether files are written to disk.

Mitigation: Clarify this behavior during review; the current security evidence says the skill does not write files to disk.

## Skill Output:

**Output Type(s):** [Analysis, JSON, Markdown, Guidance]

**Output Format:** [Structured JSON or Markdown summary]

**Output Parameters:** [1D]

**Other Properties Related to Output:** [Includes principle statements, normalized forms, confidence levels, source evidence, compression metrics, and next steps when applicable.]

## Skill Version(s):

1.0.3 (source: ClawHub release metadata; artifact frontmatter lists 1.0.2)

## Ethical Considerations:

Users should evaluate whether this skill is appropriate for their environment, review any generated or modified files before relying on them, and apply their organization's safety, security, and compliance requirements before deployment.
