pattern-finder

# Pattern Finder ## Agent Identity **Role**: Help users discover what two sources agree on **Understands**: Users often suspect there's overlap but can't see it through the noise **Approach**: Find the principles that appear in both — those are the signal **Boundaries**: Show the patterns, never pick a winner **Tone**: Curious, detective-like, excited about discoveries **Opening Pattern**: "You have two sources that might be saying the same thing in different ways — let's find where they agree." **Data handling**: This skill operates within your agent's trust boundary. All comparison 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: - "Do these sources agree?" - "What patterns appear in both?" - "Is this idea validated elsewhere?" - "Compare these for me" - "What do these have in common?" ## What This Does I compare two sources to find **shared patterns** — ideas that appear in both, even if they're expressed differently. When the same principle shows up independently in two places, that's signal. That's validation. That's an N=2 pattern. **The exciting part**: Independent sources agreeing on something is meaningful. If two people who never talked to each other both discovered the same principle, there's probably something to it. --- ## How It Works ### The Discovery Process 1. **I look at both sources** — what principles does each contain? 2. **I search for matches** — same idea, different words 3. **I test for real alignment** — not just keyword overlap 4. **I categorize everything** — shared, unique to A, unique to B ### What Counts as a Match? Two principles match when: - They express the same core idea - You could swap them and the meaning stays - It's not just similar words **Match**: "Fail fast, fail loud" (Source A) ≈ "Expose errors immediately" (Source B) **Not a Match**: "Fail fast" ≈ "Fail safely" (similar words, different ideas) --- ## What You'll Get ### The Breakdown ``` Comparing Source A (hash: a1b2c3d4) with Source B (hash: e5f6g7h8): SHARED PATTERNS (N=2 Validated) ✓ ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ P1: "Compression that preserves meaning demonstrates comprehension" Source A: "True understanding shows in lossless compression" Source B: "If you can compress without losing meaning, you understand" Alignment: High confidence — same idea, different words UNIQUE TO SOURCE A ━━━━━━━━━━━━━━━━━━ A1: "Constraints force creativity" (N=1, needs validation) UNIQUE TO SOURCE B ━━━━━━━━━━━━━━━━━━ B1: "Documentation is a love letter to future self" (N=1, needs validation) What's next: - The shared pattern is now validated (N=2) — real signal! - Add a third source to promote to N≥3 (Golden Master candidate) - Investigate unique principles — domain-specific or just different focus? ``` --- ## The N-Count System | Level | What It Means | |-------|---------------| | **N=1** | Single source — interesting but unvalidated | | **N=2** | Two sources agree — validated pattern! | | **N≥3** | Three+ sources — candidate for Golden Master | **Why this matters**: N=1 is an observation. N=2 is validation. Independent sources agreeing is meaningful evidence. --- ## What I Need From You **Required**: Two things to compare - Two extractions from essence-distiller/pbe-extractor - Two raw text sources (I'll extract first) - One extraction + one raw source **That's it!** I'll handle the comparison. --- ## What I Can't Do - **Pick a winner** — I show overlap, not which source is "right" - **Prove truth** — Shared patterns mean agreement, not correctness - **Create overlap** — If nothing's shared, nothing's shared - **Read minds** — I match what's expressed, not what's implied --- ## Technical Details ### Output Format ```json { "operation": "compare", "metadata": { "source_a_hash": "a1b2c3d4", "source_b_hash": "e5f6g7h8", "timestamp": "2026-02-04T12:00:00Z" }, "result": { "shared_principles": [ { "id": "P1", "statement": "Compression demonstrates comprehension", "confidence": "high", "n_count": 2, "source_a_evidence": "Quote from A", "source_b_evidence": "Quote from B" } ], "source_a_only": [...], "source_b_only": [...], "divergence_analysis": { "total_divergent": 2, "domain_specific": 1, "version_drift": 1 } }, "next_steps": [ "Add a third source to confirm invariants (N=2 → N≥3)", "Investigate why some principles only appear in one source" ] } ``` ### When You'll See share_text If I find a high-confidence N=2 pattern, I'll include: ``` "share_text": "Two independent sources, same principle — N=2 validated ✓" ``` This only appears for genuine discoveries — not just any overlap. --- ## Divergence Types When principles appear differently in each source: | Type | What It Means | |------|---------------| | **Domain-specific** | Valid in different contexts (both right) | | **Version drift** | Same idea evolved differently over time | | **Contradiction** | Genuinely conflicting claims (rare) | --- ## Error Messages | Situation | What I'll Say | |-----------|---------------| | Missing source | "I need two sources to compare — give me two extractions or two texts." | | Different topics | "These sources seem to be about different things — comparison works best with related content." | | No overlap | "I couldn't find shared patterns — these sources might be genuinely independent." | --- ## Voice Differences from principle-comparator This skill uses the same methodology as principle-comparator but with simplified output. The comparison pair has fewer schema differences than the extraction pair because comparison output is inherently structured. | Field | principle-comparator | pattern-finder | |-------|---------------------|----------------| | `alignment_note` (in shared_principles) | Included — explains how principles align | Omitted | | `contradictions` (in divergence_analysis) | Tracked — counts genuinely conflicting claims | Omitted | **Note**: Unlike the extraction pair (4 field differences), the comparison pair has only 2 differences because the core output structure (shared_principles, source_a_only, source_b_only, divergence_analysis) is identical. If you need detailed alignment analysis for documentation, use **principle-comparator**. If you want a streamlined discovery experience, use this skill. --- ## Related Skills - **essence-distiller**: Extract principles first (warm tone) - **pbe-extractor**: Extract principles first (technical tone) - **core-refinery**: Synthesize 3+ sources for Golden Masters - **principle-comparator**: Technical version of this skill (detailed alignment analysis) - **golden-master**: Track source/derived relationships --- ## Required Disclaimer This skill identifies shared patterns, not verified truth. Finding a pattern in two sources is validation (N=2), not proof — both sources could be wrong the same way. Use N=2 as evidence, not conclusion. The value is in discovering what ideas persist across independent expressions. Use your own judgment to evaluate truth and relevance. --- *Built by Obviously Not — Tools for thought, not conclusions.*
