Blindspot

Turn an idea — or a half-planned project already underway — into a buildable blueprint, by interviewing the user one question at a time until the unknowns run out, then deep-reading and verifying real open-source components for each part. Use this whenever someone describes something they want to build but has not specified it ('I want to build an app that…', 'I have an idea for…', 'help me plan/spec/scope this', 'turn my idea into a plan'), whenever they ask for a PRD, a spec, a product requirements document or a build plan, AND equally whenever someone says an existing project feels under-pl

# blindspot

Named for what it looks for: the two things nobody can self-report — what you assumed was too obvious to say,
and what you never considered at all.

Someone arrives with one sentence: *"an app that helps dog walkers find clients."* A plan written straight
from that sentence is fiction — every important decision gets made by whoever writes it, not by the person
who has to live with it.

This skill replaces that with two phases:

1. **Interview** — one question per message until the unknowns stop appearing, writing every answer to disk
   as it arrives.
2. **Harvest** — for each component the blueprint needs, discover real open-source projects, **deep-read their
   documentation for technical fit**, and **verify** their live GitHub metadata before recommending anything.

Phase 2 depends on phase 1. Harvesting against a half-formed idea produces a list of libraries for a product
nobody has decided on yet. Finish the interview first, or at least reach a component list the user agrees
with.

## Two ways in

**From nothing** — one sentence and an intention. Start at "before the first question" below.

**From a project already underway** — someone with code, docs and momentum who says it was never planned
properly, that it is full of gaps, or that they are no longer sure what they have actually decided. This is
the more common case and the more valuable one, because the gaps are load-bearing by the time anyone notices
them.
