Show HN: Spec-Driven Development Workflow for Claude Code

The sddw author released a Claude Code plugin that splits work into requirements, code analysis, and design specs, then clears context after each step to keep cost and context focused.

Why it matters: HKR-H/K/R all pass for a Claude Code workflow with a concrete spec-and-context mechanism. It stays in the 72–77 featured band because the post lacks benchmarks, adoption data, or an official Anthropic release.

Take

sddw makes the right boring bet: do not let Claude Code carry a whole engineering task inside one swollen context. The plugin splits work into three spec layers—requirements, code analysis, design—then executes subtasks one by one. It clears context after each step and writes specs to disk. That attacks the failure mode practitioners actually hit: goal drift, stale assumptions, and polluted context.

I like this class of tool because it treats coding agents as unreliable workers that need external state. The article gives no benchmark, no cost reduction number, and no success-rate comparison; the HN post has only 5 points so far. Still, compared with the usual Cursor or Claude Code “giant prompt and pray” workflow, layered specs plus context resets look closer to something a team can standardize.
