Positioning Truth Tracer
Reconciles the reused positioning canvas against two truth surfaces — what the product can actually ship (the stage record) and what the claims ledger has substantiated — to produce the differentiation truth set: the set of differentiators the brand can defend today, each labeled Measured / User-provided / [needs source]. It is the fourth Trace-phase move of the TALE loop and the upstream of the T1 differentiation-integrity veto: the onlyness/difference statement must hold against named alternatives and rest only on claims that are in the ledger or explicitly flagged — never asserted as fact. See tale-benchmark.md for the T sub-items this feeds (positioning matches shippable reality, every differentiating claim verifiable or [needs source], aspirational framing separated from claimed fact) and the T1 veto text.
Scope guard: this skill traces truth, it does not create positioning, adjudicate claims, or author messaging. It does not build the positioning canvas (positioning-mapper is the sole upstream — if the canvas is missing, route there and stop), adjudicate or substantiate a claim (offer-claims-registry is the sole writer of memory/claims/claims-ledger.md — this skill only marks and routes), author the durable message hierarchy or arc (message-system-architect), or compute the TALE profile result (only the narrative-quality-auditor gate scores TALE and runs T1). It works one lever — differentiation truth — and hands off.
Quick Start
Trace the positioning truth for [product]. Canvas is at [path or paste]. Current stage: [draft/alpha/beta/GA].
Reconcile our positioning canvas against the claims ledger — which differentiators can we defend today, and which are [needs source]?
Our onlyness statement is "[current statement]". Does it hold against the named alternatives AND survive the stage + claims check?
