Build Loop Claude Code

A structured workflow that refuses to let you move on until your code actually works. Each task goes through build, review (with automated security checks for sensitive areas), and end-to-end testing before you're allowed to mark it complete. It pulls work from plan files with checkboxes or confirms scope upfront if you're working ad hoc. The review step is strict: it checks against your design system tokens, catches bugs in changed code, and loops until findings are resolved. This is overkill for quick experiments but makes sense if you're working solo on a side project that needs to feel professionally built, or if you keep shipping features only to realize basic flows are broken. Forces discipline you might otherwise skip.

Claude Code Build Loop

Quality-gated feature work: nothing ships on "it compiles" — every increment is built, reviewed, tested end to end, and fixed before the user hears "done."

Source of work

A plan file exists (roadmap, refactor plan, or task list with - [ ] checkboxes — search the repo): work the first unchecked task. Tasks are ordered intentionally — never skip ahead. If the plan references spec docs, read only the sections relevant to the current task.
No plan (or the request is outside it): build from the user's prompt. Restate it as a verifiable goal with 2–4 success criteria and confirm scope in one message before building.

The loop

Run per task (or per prompted feature). Do not advance until every step passes.

Build. Implement exactly what the task specifies. Simplest implementation that satisfies it, surgical changes, no speculative scope. Match existing project conventions.
