--- name: PBE Extractor version: 1.0.2 description: Extract invariant principles from any text — find the ideas that survive rephrasing. homepage: https://github.com/live-neon/skills/tree/main/pbd/pbe-extractor user-invocable: true emoji: 📐 tags: - extraction - principles - methodology - best-practices - summarization - knowledge-management - documentation - analysis - openclaw --- # 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 understand" **Fail**: "Small files" ≈ "Fast files" (keyword overlap, different meaning) --- ## Extraction Framework ### Step 1: Content Analysis Read the source and identify: - Domain/subject matter - Structure (lists, prose, code) - Density of ideas - Potential principle clusters ### Step 2: Candidate Identification For each potential principle: - Extract the core statement - Test against rephrasing criteria - Assign confidence level - Note source evidence ### Step 2.5: Normalize Candidates For each candidate principle, create a normalized form for semantic matching: **Normalization Rules**: 1. **Actor-agnostic**: Remove pronouns (I, we, you, my, our, your) 2. **Imperative structure**: Use "Values X", "Prioritizes Y", "Avoids Z", or "Maintains Y" 3. **Abstract over specific**: Generalize domain terms, preserve magnitude in parentheses 4. **Preserve conditionals**: Keep "when X, then Y" structure if present 5. **Single sentence**: One principle = one normalized statement (under 100 characters) **Example**: | Original | Normalized | |----------|------------| | "I always tell the truth" | "Values truthfulness in communication" | | "Keep Go functions under 50 lines" | "Values concise units of work (~50 lines)" | | "When unsure, ask" | "Values clarification when uncertain" | **When NOT to Normalize**: - Context-bound principles (e.g., "Never ship on Fridays") - Numerical thresholds integral to meaning - Process-specific step sequences For these, set `normalization_status: "skipped"` and use original text. **Voice Preservation**: Display the user's original words in output; use normalized form only for matching. ### Step 3: Compression Validation Verify extraction quality: - Calculate compression ratio - Check principle coverage - Identify any lost information - Adjust confidence if needed --- ## Confidence Levels | Level | Criteria | Language | |-------|----------|----------| | **high** | Explicitly stated, unambiguous | "This principle states..." | | **medium** | Implied, minor inference needed | "This appears to suggest..." | | **low** | Inferred from patterns | "This may imply..." | --- ## Output Schema ```json { "operation": "extract", "metadata": { "source_hash": "a1b2c3d4", "timestamp": "2026-02-04T12:00:00Z", "source_type": "documentation", "word_count_original": 1500, "word_count_compressed": 320, "compression_ratio": "79%", "normalization_version": "v1.0.0" }, "result": { "principles": [ { "id": "P1", "statement": "I always tell the truth, even when it's uncomfortable", "normalized_form": "Values truthfulness over comfort", "normalization_status": "success", "confidence": "high", "n_count": 1, "source_evidence": ["Direct quote from source"], "semantic_marker": "compression-comprehension" } ], "summary": { "total_principles": 5, "high_confidence": 3, "medium_confidence": 2, "low_confidence": 0 } }, "next_steps": [ "Compare with another source using principle-comparator to validate patterns (N=1 → N=2)", "Document source_hash for future reference: a1b2c3d4" ] } ``` `normalization_status` values: - `"success"`: Normalized without issues - `"failed"`: Could not normalize, using original - `"drift"`: Meaning may have changed, added to `requires_review.md` - `"skipped"`: Intentionally not normalized (context-bound, numerical, process-specific) --- ## Terminology Rules | Term | Use For | Never Use For | |------|---------|---------------| | **Principle** | Invariant truth surviving rephrasing | Opinions, preferences | | **Pattern** | Recurring structure across instances | One-time observations | | **Observation** | Single-source finding (N=1) | Validated principles | | **Confidence** | Evidence clarity | Certainty of truth | --- ## Error Handling | Error Code | Trigger | Message | Suggestion | |------------|---------|---------|------------| | `EMPTY_INPUT` | No content provided | "I need some content to analyze." | "Paste or reference the text you want me to extract principles from." | | `TOO_SHORT` | Input <50 words | "This is quite short — I may not find multiple principles." | "For best results, provide at least 200 words of content." | | `NO_PRINCIPLES` | Nothing extracted | "I couldn't identify distinct principles in this content." | "Try content with clearer structure or more conceptual density." | --- ## Quality Metrics ### Compression Ratio Targets | Ratio | Assessment | |-------|------------| | <50% | Minimal compression, may contain redundancy | | 50-70% | Good compression, typical for dense content | | 70-85% | Excellent compression, strong extraction | | >85% | Verify no essential information lost | ### Principle Quality Indicators - Clear, testable statements - Appropriate confidence levels - Specific source evidence - Useful semantic markers --- ## Related Skills - **principle-comparator**: Compare two extractions to validate patterns (N=1 → N=2) - **principle-synthesizer**: Synthesize 3+ extractions to find Golden Masters (N≥3) - **essence-distiller**: Conversational alternative to this skill - **golden-master**: Track source/derived relationships with checksums --- ## Required Disclaimer This skill extracts PATTERNS from content, not verified truth. All extracted principles: - Start at N=1 (single source observation) - Need validation through comparison (N≥2) - Reflect structure, not correctness - Should be reviewed before application --- *Built by Obviously Not — Tools for thought, not conclusions.*
