Examples

Example input
Use the supplied interview transcript, onboarding timeline, and verified support metrics to draft a B2B SaaS case study. Do not claim revenue impact because no revenue data was measured.
Example output
An evidence map, unsupported-claim warnings, a long-form case study, approved quotation placeholders, measurable results, limitations, a short summary, and an approval checklist.

FAQ

Can this skill invent a customer quote to improve the story?
No. Quotations must come from supplied material and require approval.
Can it write a case study without numeric results?
Yes, but it must use verifiable qualitative outcomes and avoid implying unmeasured impact.
How are unsupported claims handled?
They are removed, qualified, or marked for evidence rather than presented as fact.
Can it anonymize the customer?
Yes, using approved descriptors while avoiding details that could re-identify the organization.
Does it distinguish correlation from causation?
Yes. It avoids claiming the product caused an outcome unless the evidence supports that conclusion.
How is this different from a testimonial writer?
A case study builds a sourced, contextual narrative with implementation, results, limitations, and approval evidence.
