Concepts

Shared vocabulary for the guide. Prefer the lifecycle and Architecture before reading every concept. Strategies and practices cite these when a mechanism matters.

The stance:

• This is Fine (stance)
• Skills as Named Cuts
• Smallest Next Step

How you know:

• Evidence over Vibes
• Quality regimes — deterministic compute ≠ product UX ≠ generative/evals
• Bugs & debt — a bug is a bug; debt is unpaid interest by type
• Quality trace (DocSlime + BDD) — promise → scenarios → evidence → observation
• Vision-Tied Goals

How you choose tools (Architecture choosers):

• Architecture hub — shape · language · framework · placement · hosts
• Language selection — defaults: Python, TypeScript/Node, Rust; exceptions: Kotlin, Swift, Godot
• Web framework selection — React + Next.js on Vercel; Astro Starlight for docs

How agents behave:

• Agent Agency
• Work Ownership
• Stop Conditions
