Descriptions:
VelvetShark’s video breaks down the “spec workflow” for Claude Code—a technique originally shared by Thariq, an Anthropic engineer, that attracted 1.2 million views and nearly 9,000 bookmarks in three days. The core idea inverts the usual prompting model: rather than telling Claude what to build, you provide a minimal one-sentence spec and let Claude interview you with probing questions until requirements are fully defined, then generate a detailed specification file before any code is written.
In a live demonstration, the creator starts with a single sentence—”Build a CLI tool to save and search bookmarks”—and pastes a specific prompt instructing Claude Code to use the AskUserQuestionTool and interview exhaustively. Claude asks 32 questions covering tech stack, data model, command structure, storage format, edge cases, and explicit non-goals, producing a 157-line SPEC.md file in minutes. A fresh Claude Code session then implements the entire bookmark CLI tool in one shot with no additional input, and the resulting tool works immediately after npm link.
The video covers when to skip the workflow entirely (small, well-defined tasks with no ambiguity), how to add anti-goals to prevent scope creep, and how to convert the interview prompt into a reusable slash command stored at `~/.claude/commands/interview.md`. The creator estimates the spec phase replaces two or more hours of manual edge-case thinking, front-loading all architectural decisions before a single line of code is written.
