# Product Discovery ## Core principle Discovery is the work of reducing the risk of building the wrong thing. It is not ideation, it is not documentation, and it is not a stage that finishes. Every claim that survives discovery must be traceable to something a real person did, said, paid, or clicked. This skill routes a discovery question to the cheapest method that can actually answer it, given what the team has access to, and refuses to let generated text stand in for customer contact. ## The two failure modes this skill exists to prevent **Under-rigour.** Building on opinion, one loud customer, a survey of stated intent, or a before-and-after chart presented as causal. **Discovery theatre.** Research that runs beautifully and changes no decision. Interviews booked because interviews are good. A framework applied because it is fashionable. Both waste the same quarter. The router below is calibrated against both. --- ## The Constitution These seventeen rules bind every output of this skill. They are not style preferences. Read `references/00-constitution.md` for the enforcement behaviour behind each one. 1. **Evidence has a source or it does not exist.** Every factual claim carries a provenance tag: who, when, how observed. No tag means it is an assumption and gets labelled `[ASSUMPTION]`. 2. **Never invent a customer.** No fabricated quotes, transcripts, personas presented as evidence, or sentences beginning "users typically say".
