PRD, spec, and build-plan templates you can generate and adapt

A blank document is the most expensive part of writing a spec. Not because the writing itself is hard, but because staring at an empty page forces you to invent structure and content at the same time — decide what sections a good PRD even has while also trying to describe your actual product. Templates remove one of those two problems. You still have to know what you're building; you no longer have to guess what "done" looks like as a document.

What a good spec template actually contains

A template that's worth using does more than provide headings. It should show you the shape of good requirements (specific, testable, not "the system should be fast"), a place for explicit constraints and non-goals, an architecture section that forces a real decision instead of a paragraph of hedging, a validation or acceptance-test section that defines "done" in a way a reviewer can check, and a task breakdown granular enough to hand to one person — or one coding-agent run — at a time.

Every template on this hub is the structure Thought2Build's own generation pipeline produces: a SPEC with requirements and constraints, a PLAN with architecture and sequencing, a HARNESS of acceptance criteria, and a TASKS breakdown that traces back to both. You can read a template here to see what a strong first draft looks like for a given kind of project — a SaaS PRD, an API spec, an internal tool brief — and then generate and adapt your own from a one-line idea instead of copy-pasting a static doc and hoping it fits.

These are starting points, not straitjackets. The point of seeing the shape of a strong spec up front is that you can tell, fast, which sections apply to your project and which don't — which is a much better position than discovering a missing acceptance-criteria section three weeks into a build.
