Product thinking, wired into your coding agent. A structured product development framework that runs inside Claude Code, covering the full product lifecycle, from raw idea through domain modeling to delivery, as 51 connected skills you invoke when you need them, not a waterfall you follow in sequence.
Not because teams lack talent or effort - because the knowledge is scattered. Validated insights that never made it into the spec. Business rules buried in Slack threads. A PRD nobody reads after week two. A new developer who spends three days asking basic questions about how the system works.
Pureinn was built to close that gap. Every skill produces an artifact the next skill can read. The system records decisions and carries context forward, so the team stays in sync without meetings to compensate for missing documentation.
“The waste is not in the doing. It is in the re-doing.”
Re-litigating decisions already made. Re-explaining context that was never written down. Building features nobody validated.
Customer research, market analysis, hypothesis testing with Go/No-Go gates before committing to build.
Entities, state machines, business rules, and decision tables as living registers the codebase references.
KANO classification, Value vs. Complexity scoring, dependency mapping, MVP scope, Delivery Stripes.
Per-feature functional specs written just before build, not months ahead when everything is still uncertain.
Prototyping, audit, stress-testing, root cause diagnosis, meeting notes, onboarding briefs.
All of it connects. A persona from Discovery feeds a JTBD analysis → JTBD feeds hypothesis testing → validated hypotheses feed the PRD → the PRD's Business Capabilities feed entity extraction → entities feed feature derivation → features feed the JIT spec. Every step has a known input and a known output.
Built from watching the same problems appear in different forms.
Over a decade working across technology, business, and product - in labs, early-stage startups, small teams, and larger corporate environments. A corporate team drowning in documentation nobody uses. A startup building on gut feeling with no validation.
An agency re-explaining a client's own domain back to them every six months because nothing was written down. The common thread was never the tools - it was the absence of a structure that scales down for one person and up for a team, unchanged.
Every design decision is made with one question in mind: does this move the product forward, or does it just create process? Speed of impact and real value delivery are the constraints, not completeness for its own sake.
