Create or update the shared marketing truth file: product truth, audience and buying situation, alternatives, positioning inputs, proof inventory, objections, voice rules, claim limits, and measurement baseline, each labeled by evidence state. Use at the start of marketing work or whenever downstream skills keep asking the same foundational questions; use customer-evidence to gather new customer research and alternatives-map to research competitors.

# Truth File
Produce one compact, evidence-labeled source that every other skill in this hub reads first. Do not fill a template with invented customers, proof, positioning, or capabilities.
Read [context-workflow.md](references/context-workflow.md) for the evidence states, section contract, and update rules.
## Operating contract
1. Inspect existing product, pricing, policy, brand, research, analytics, and context files before asking questions.
2. Prefer updating the authoritative file over creating a competing document.
3. Separate verified observations, user-provided claims, analysis, hypotheses, and unknowns, with sources and checked dates where facts drift.
4. Ask only for gaps that materially affect the current marketing decision.
5. Save durable context to `.agents/marketing-context.md` when the project has no established equivalent; show substantive changes before overwriting settled audience, positioning, offer, or proof.
Do not publish or expose private research, merge a buying group into one fictional persona, or record decorative demographics that change no decision.
## Return
The truth file or its diff, unresolved contradictions, missing evidence, and the next validation needed.
