📐 Spec-Kit Architecture: Specifications Precede Code

The Spec-Kit framework (github.com/github/spec-kit) structures developer interactions across 6 mandatory slash-commands: /constitution (inviolable project rules), /specify (functional spec), /clarify (ambiguity resolution), /plan (architecture roadmap), /tasks (atomic work packages), and /implement (execution).

Agents are strictly restricted from editing source code until specifications and acceptance criteria pass verification. This preempts 90% of LLM mistakes — from hallucinating dependencies to wiping critical lifecycle hooks.

Source code is treated as an ephemeral compiler output; executable specifications and verification suites form the ultimate ground truth.

🚀 The Multi-Agent Engineering Paradigm

Worktrunk eliminates the primary bottleneck of concurrent AI prompting: file lock collisions and redundant build cycles. By orchestrating git worktrees and shared compilation caches, a single developer can test 5 parallel feature implementations simultaneously.

In 2026, engineering leverage is no longer measured in raw lines of code, but in specification fidelity and rigorous architectural constraints.
