PRD-to-Feature-List Automation Cuts a One-Hour Chore to 25 Minutes

The bottleneck in turning a PRD into a buildable spec isn't intelligence — it's the repetitive mechanical steps of reading, screenshotting, and formatting. Automating that end-to-end eliminates omission errors and produces a list the whole team can use, not just cryptic personal notes. The Skill packaging means the workflow becomes a portable asset rather than a one-off script.

A frontend developer replaced the tedious pre-iteration ritual of manually copying PRD changes into an Excel feature list with a single TRAE Work command. The tool ingested an HTML PRD, an HTML interaction prototype, and an xlsx template, then extracted all six requirement changes — including rules, operation steps, and acceptance criteria that manual work routinely skipped. It spun up a local HTTP server to serve the prototype, navigated to each scene via URL parameters, and took screenshots automatically before generating the final spreadsheet via Excel COM automation. The whole run took 25 minutes, down from the usual hour, and the output was more complete and team-readable than the shorthand-only manual version. The workflow was then distilled into a reusable Skill package with PowerShell-based xlsx parsing and screenshot scripts, so the same pipeline transfers to other projects without rewriting prompts.
