Who Am I Failing Right Now?

I'm building Humic, but I want to make sure I'm actually building the right thing.

So I added a personas md file to my codebase. Not vague archetypes, but specific people with specific workflows, frustrations, and goals. A freelance designer juggling four active clients, pushing token updates to dev teams who all expect a different format. A senior designer who's been burned by engineers changing color values directly in the codebase, silently, without her knowing.

Whenever I'm reviewing what I've built or planning what's next, I run Claude Code against that file. It audits the current state of the product through the lens of each persona, and uses the Linear MCP to write issues for every gap it finds directly into my backlog. Not just "this is missing" but why it matters for that specific person, and a concrete suggestion for what to do about it.

The result is a backlog that actually reflects who I'm building for, not just what I felt like building.

If you're building something, try this. Write down two or three real people you're building for. Drop it in your codebase. Then ask an AI agent: "audit what I've built against these personas and create issues for every gap you find." It takes maybe ten minutes to set up, and it will surface things you didn't know you were missing.

The question stops being "what should I build next?" and becomes "who am I failing right now?"

And if you're not using Linear yet: I'm not sure what you're doing, but I do know you're doing it wrong.
