Do We Need This has three parts that work together:

The discovery skill. A set of instructions for Claude Code, Codex, or another AI tool. It interviews you about a piece of work, asks the questions that fit it, and ends with a draft decision. It needs no account.
The workspace. A web app at doweneedthis.com/app that stores the process map, evidence, questions, and decisions. Your team uses it for feedback forms, live voting, and confirming decisions.
The desktop app. The same workspace, kept in a file on your computer.

Run the discovery skill on one piece of work and read the summary.
Create a workspace and a project, then connect your AI tool and save the assessment.
Add evidence and open questions to the map in the workspace.
Invite contributors and run written feedback or a workshop on the questions people disagree about.
Propose and confirm a decision.
If the project needs a document, freeze a baseline and have your AI tool produce it.
If you tried stopping something, record the outcome at the review date.

An AI tool that supports skills or MCP: Claude Code or Codex.
A web browser.
For the workspace: an account. A full seat costs $99 per month and includes 20 contributor seats. The trial lasts 14 days and requires a card.
