Source of Truth Creator v1.1

Purpose: Create Source of Truth documents that are epistemically calibrated and Clarity Gate-ready.

Core Question: "When someone reads this document, will they have accurate confidence in each claim?"

Core Principle: "A Source of Truth that overstates certainty is worse than no Source of Truth -- it creates false confidence. Calibration matters more than completeness."

Prior Art: This skill synthesizes established frameworks (GRADE, ICD 203, PRISMA, IIA Standards). Our contribution is practical accessibility, not new concepts. See docs/PRIOR_ART.md.

Origin: Extracted from Clarity Gate meta-verification (2025-12-21). When we ran Clarity Gate on its own Source of Truth document, we discovered failure modes specific to SoT creation. See: Clarity Gate SOURCE_OF_TRUTH.md

When to Use This Skill

Use when:

• •Claims will be cited elsewhere
• •Decisions depend on accuracy
• •Document will be read by people who don't know your epistemic standards
• •Creating authoritative reference for a project
• •Consolidating research from multiple sources

User phrases that trigger this skill:

• •"Create a source of truth for..."
• •"Document the verified state of..."
• •"I need an authoritative reference for..."
• •"Consolidate this research into..."

Do NOT use when:

• •Taking meeting notes (use simple markdown)
• •Brainstorming (uncertainty is the point)
• •Personal project logs (overkill)
• •Quick summaries (no verification needed)
• •Internal team scratchpads

For lightweight documentation, use plain markdown. This skill is for documents where epistemic rigor matters.

The Recursion Problem

Source of Truth documents face a unique challenge:

1. •A Source of Truth claims to be "VERIFIED"
2. •But verification requires... a Source of Truth
3. •At some point, claims bottom out in human judgment

This skill doesn't solve the recursion -- it makes it visible.

The goal is not infinite regress verification. The goal is:

• •Clear marking of WHERE claims bottom out
• •Honest confidence levels for each claim type
• •Visual calibration so readers don't over-trust

The Eight Failure Modes

These patterns emerged from meta-verification of the Clarity Gate Source of Truth document. Modes 1-5 were discovered during that verification; Mode 6 was identified during review as a common pattern.

1. THE VERIFIED HEADER TRAP

Problem: Document header says "Status: VERIFIED" but body contains estimates, hypotheticals, and acknowledged uncertainties.

Why it matters: Readers skim headers. A "VERIFIED" badge creates false confidence in all contents.

Fix: Always qualify the header status, or use the Verification Summary box.

2. THE INTERNAL MEASUREMENT TRAP

Problem: Internal measurements (timing, counts, informal tests) marked as "Verified" with the same formatting as externally-validated claims.

Why it matters: "12 seconds" from one informal run is not equal to "12 seconds" from rigorous benchmarking.

Fix: Add methodology notes: [MEASURED: n=X, conditions Y], [INFORMAL: single observation], [ESTIMATED: author judgment]

3. THE SELF-ASSESSMENT TRAP

Problem: Self-assigned scores (8.8/10, "High confidence") presented in tables that look like external validation.

Why it matters: Numeric scores trigger authority heuristics. "9.5/10" looks objective even when self-assigned.

Fix: Always label self-assessments explicitly in the table header or row.

4. THE ABSENCE-AS-PROOF TRAP

Problem: "No prior art found" marked as "Verified" when absence of evidence is not equal to evidence of absence.

Why it matters: A more thorough search might find what you missed. Gap claims are inherently uncertain.

Fix: Add epistemological caveat to all "X doesn't exist" claims.

5. THE ILLUSTRATIVE-AS-DATA TRAP

Problem: Hypothetical examples (96% efficiency, 50-claim document) appear in data tables alongside measured values.

Why it matters: Examples become cited as data. "~96% reduction" migrates from illustrative to factual.

Fix: Keep illustrative examples OUT of data tables. Use separate "Examples" sections.

6. THE STALENESS TRAP

Problem: "Verified: 2025-12-21" on rapidly-changing claims (competitor features, pricing, URLs).

Why it matters: A URL verified yesterday may 404 today. External claims have different shelf lives.

Fix: Add staleness markers:

• •[STABLE] -- historical facts, standards, completed events
• •[CHECK BEFORE CITING] -- competitor features, pricing, team info
• •[VOLATILE -- verify before use] -- URLs, API endpoints, market data
• •[SNAPSHOT -- [date] only] -- stock prices, user counts, rankings

7. THE TEMPORAL INCOHERENCE TRAP

Problem: Document dates are wrong at creation time — not stale, just incorrect.

Why it matters: A document claiming "Last Updated: December 2024" when created in December 2025 will mislead any reader or LLM about temporal context. Unlike staleness (claims that decay), this is an error at creation.

Sub-checks:

1. •Document date vs current date: Is "Last Updated" correct? In future? Suspiciously old?
2. •Internal chronology: Are version numbers, changelog entries, event dates in logical sequence?
3. •Reference freshness: Do "current", "now", "today" claims have date qualifiers?

Fix:

• •Verify "Last Updated" matches actual update date
• •Check all dates are in chronological order
• •Add "as of [date]" to time-sensitive claims
• •Use future tense for planned items

Relationship to Mode 6 (Staleness):

• •Mode 6 catches claims that WILL become stale (volatility)
• •Mode 7 catches dates that are ALREADY wrong (incoherence)

8. THE UNVERIFIED SPECIFIC CLAIMS TRAP

Problem: Specific numbers (pricing, statistics, rates) included in Verified Data without actually verifying them.

Why it matters: Specific numbers look authoritative. "$0.005 per call" in a Source of Truth document will be trusted and propagated — even if it's 10x wrong. These are "confident plausible falsehoods."

Red flags requiring verification:

Fix options:

1. •Verify and cite: Add source with date
2. •Move to Estimates: If unverifiable, don't put in Verified Data
3. •Generalize: "low cost" instead of "$0.005"
4. •Add uncertainty: "reportedly ~$0.005 (unverified)"

Relationship to Mode 6 (Staleness):

• •Mode 6 marks claims that will decay (pricing marked VOLATILE)
• •Mode 8 catches claims that were never verified in the first place

Key insight: A claim can have correct staleness markers AND still be wrong. "$0.005 [VOLATILE]" is properly marked for staleness but may still be factually incorrect.

Staleness Risk Categories

Note: Staleness markers (Mode 6) address FUTURE decay. But claims must also be VERIFIED at creation time (Mode 8). A claim marked [VOLATILE] that was never verified is still wrong.

Workflow:

1. •Use Source of Truth Creator to draft the document
2. •Run Clarity Gate on the result
3. •Iterate until PASS

What This Skill Does NOT Do

• •Does not verify external claims (use web search, citations)
• •Does not replace domain expertise
• •Does not guarantee completeness
• •Does not solve the recursion problem (only makes it visible)

This skill ensures: Documents are structured for epistemic honesty, with appropriate uncertainty markers and reader calibration.
