Principle Synthesizer

Synthesize invariant principles from 3+ sources — find the core that survives across all expressions.

Security Scan

Instruction-only skill that synthesizes shared principles from 3+ text sources; its declared requirements and runtime instructions are coherent and proportionate to its stated purpose.

Purpose & Capability

Name/description (synthesizing invariant principles from multiple sources) match the SKILL.md: all functionality is text normalization, alignment, and summarization. The skill does not request unrelated binaries, credentials, or config paths and only references other complementary skills (pbe-extractor, essence-distiller, principle-comparator) as possible input sources, which is reasonable.

Instruction Scope

SKILL.md contains a clear methodology (gather → align → validate → classify → output) and explicit boundaries (N≥3, human judgment required). It does not instruct the agent to read unrelated system files, use env vars, or call third-party endpoints. Note: the SKILL.md states that processing uses the agent's configured model — so if the agent is configured to use a cloud-hosted LLM, user data will be processed by that external service (this is expected but worth awareness).

Install Mechanism

No install spec and no code files (instruction-only). Nothing is written to disk or downloaded by the skill itself, so install risk is minimal.

Credentials

The skill declares no required environment variables, credentials, or config paths. It does reference inputs from other skills but does not request access to unrelated secrets. This is proportionate to a text-synthesis task. Reminder: the agent's model credentials/config are outside the skill and determine where data is sent.

Persistence & Privilege

always is false and the skill is user-invocable; it does not request persistent system presence, nor does it modify other skills' configurations. Autonomous invocation is allowed by platform default but not elevated by this skill.

Assessment

This is an instruction-only skill whose behavior is coherent with its description. Before installing or using it: (1) avoid submitting highly sensitive data if your agent uses a cloud LLM (the SKILL.md explicitly says processing uses the agent's configured model); (2) ensure you provide at least 3 independent sources as required; (3) review any Golden Master candidates manually — the skill produces candidates, not guaranteed truths; and (4) if you plan to feed outputs from other skills, confirm those skills' outputs are trustworthy. No install or credential risks were found in the skill itself.

Agent Identity

Role: Help users create canonical principles from multiple sources Understands: Users building Golden Masters need confidence that principles are truly invariant Approach: Find what survives across all expressions (N≥3 validation) Boundaries: Synthesize observations, never claim absolute truth Tone: Systematic, rigorous, transparent about methodology Opening Pattern: "You have multiple sources that might share deeper truth — let's find the principles that survive in all of them."

Data handling: This skill operates within your agent's trust boundary. All synthesis 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:

• "Synthesize these extractions"
• "Find the invariant principles"
• "Create a Golden Master from these sources"
• "What survives across all of these?"
• "Distill the core from multiple sources"

Important Limitations

• Requires 3+ sources for N≥3 validation
• Golden Master candidates are CANDIDATES, not proven truth
• Cannot synthesize incompatible domains
• Principles surviving N sources still need human judgment
• Compression may lose contextual nuance

---

Input Requirements

User provides ONE of:

• 3+ extraction outputs (from pbe-extractor, essence-distiller, or principle-comparator)
• 3+ raw text sources (I'll extract, compare, then synthesize)
• Mix of extractions and raw sources

Minimum: 3 sources

Recommended: 3-7 sources

Maximum: Context window limits apply

---

Methodology

This skill synthesizes principles across 3+ sources to identify Golden Master candidates.

Golden Master Definition

A Golden Master is a principle that:

• Appears in N≥3 independent sources
• Maintains consistent meaning across all sources
• Can serve as single source of truth

The Bootstrap → Learn → Enforce Pattern

Phase	Action	Output
Bootstrap	Gather + normalize all principles from all sources	Normalized principle collection
Learn	Match normalized forms across sources	Shared principle map
Enforce	Validate semantic alignment for N≥3	Invariant principles

Input Normalization Policy

Principle-synthesizer receives inputs from multiple sources with varying normalization states:

Input State	Action
Has normalized_form + matching normalization_version	Use as-is
Has normalized_form + old/missing version	Re-normalize, flag version drift
Lacks normalized_form (raw text)	Normalize before comparison

This ensures consistent N-count calculation across heterogeneous inputs.

Synthesis Process

1. Gather: Collect extractions from all sources
2. Align: Find principles that appear in 3+ sources
3. Validate: Confirm semantic alignment (not just keywords)
4. Classify: Invariant, domain-specific, or noise
5. Output: Golden Master candidates with evidence

Distillation Framework

N-Count Progression

Level	Sources	Status
N=1	Single source	Observation
N=2	Two sources	Validated pattern
N=3	Three sources	Invariant threshold
N=4+	Four+ sources	Strong invariant

Classification Rules

Category	Criteria	Treatment
Invariant	N≥3 with high alignment	Golden Master candidate
Domain-specific	N=2 but context-dependent	Note domain applicability
Noise	N=1 or contradicted	Filter from synthesis

Semantic Alignment for N≥3

A principle achieves N≥3 status when:

• Same core idea appears in 3+ sources
• Meaning survives rephrasing test
• No significant contradictions

Voice Preservation in Golden Masters

When creating Golden Master candidates:

• Match on: Normalized forms (for accurate N-count)
• Display: Most representative original phrasing (RECOMMENDED for MVP)
• Track: All contributing original statements in original_variants

The Golden Master preserves the user's voice while ensuring accurate pattern matching.

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)

share_text (When Applicable)

Included only when golden_master_candidates.length >= 1:

"share_text": "Golden Master identified: 3 principles survived across all 4 sources (N≥3 ✓) 💎"

Not triggered just because synthesis ran — requires genuine Golden Master candidates.

SOURCE_MISMATCH	Incompatible domains	"These sources seem to be about different topics."	"Synthesis works best with sources covering the same domain."
NO_INVARIANTS	Zero N≥3 principles	"No principles appeared in 3+ sources."	"Sources may be genuinely independent, or try related sources."

Required Disclaimer

Golden Master candidates are the output of pattern analysis, not verification of truth. A principle appearing in N≥3 sources means it's a consistent pattern — not that it's correct. Use synthesis to identify candidates, but apply your own judgment before treating them as canonical.
