Spec-first development enforces a deliberate spec/planning loop for non-trivial tasks. By creating spec.md, todo.md, and decisions.md before coding, teams reduce "looks right" failures and ship with robust tests.

Spec-first development prevents 'looks right' failures by enforcing explicit planning before coding. Write spec.md to freeze decisions, create todo.md for stepwise execution, and document tradeoffs in decisions.md. This delays implementation until requirements and constraints are clear, reducing costly rework on non-trivial projects.
Create a spec-first workflow: frame the problem and surface constraints, generate spec.md to capture decisions, build todo.md with testable steps, then execute in small diffs with frequent verification. This produces durable artifacts for diffing, re-use, and adversarial review before shipping.
Use spec-first planning for new features, projects, or changes spanning 3+ files with unclear requirements or explicit tradeoffs. It's essential for non-trivial software development where decisions need to be frozen upfront and tests drive implementation.
Spec-first treats the implementation phase as executing a junior engineer's clear interfaces and tests. By planning and documenting decisions upfront, you catch ambiguities before coding, enable adversarial review, and ensure robust test coverage reduces rework and post-release failures.
Spec-first applies to non-trivial efforts requiring explicit tradeoffs, typically 3+ files or unclear requirements. Small, straightforward changes or single-file edits don't require the full planning loop; reserve it for projects where decisions and constraints justify documented specs and stepwise execution.
