Thariq’s Fable 5 Mindset—Finding Your “Unknown Variable”

1/ Someone asked Thariq, the developer of Claude Code, why the things he makes with Fable 5 always turn out better.

He said the secret is an old truth: The map is not the territory. 🧵 https://t.co/tt1dK9djjk

2/ The map is your prompt, skills, and context given to Fable; the territory is where the real work happens—the codebase, the real world, and the actual constraints.

He calls the gap between them the unknown variable.

3/ He breaks down the unknown into four categories: Known knowns (clearly written in your prompt), known unknowns (you know you don’t understand), unknown knowns (obvious at a glance but not written down), and unknown unknowns (things you never even thought of).

4/ His methodology spans three phases: Pre-implementation — blind spot checks, brainstorming, face-to-face questions, references, implementation plan; During implementation — have Fable log decisions that deviate from the plan; Post-implementation — report docs and self-test Q&A.

5/ For example:

In the pre-implementation phase, he directly asks Fable to do a “blind spot pass” — in completely unfamiliar territory, he has Fable first help him identify blind spots he didn’t even know to ask about, then reorganizes the prompt accordingly.

6/ In the post-implementation phase, he bundles the prototype, requirements doc, and implementation notes into a single document, leading with a demo GIF — because reviewers face as many unknowns at the start as he did. Clarifying these first speeds up their approval.

7/ At its core, this methodology is about constantly turning “unknown unknowns” into knowns — every brainstorm, interview, reference, and report is about surfacing overlooked areas before things get expensive.

How do you usually align understanding with AI?
