Scope Cutter

By Composal

Before engineering starts, writes a dated scope cut: the problem, what is in, what is out, the risks, and how you will know it is done. It drafts and asks questions; it never commits the team to dates or changes the roadmap on its own.

Works with Notion, Linear, and GitHub

About this agent

Projects grow when nobody writes down what is out. Scope Cutter is a Composal agent that writes a one-page product spec before engineering starts: the problem, what is in, what is out, the risks, and how you will know it is done. It drafts and asks questions, and the sign-off stays with your team.

What it does

  • Starts from the problem: who has it, the evidence from tickets, calls or data, and what happens if you do nothing. It says when evidence is thin.
  • Reads your codebase and current product to describe how things work today and name the parts likely to change.
  • Lists the smallest set of in-scope behaviours as observable outcomes, and states the out-of-scope items people will assume are included.
  • Writes acceptance checks a tester could run, the post-launch signal to watch and where to find it, risks with how to retire each, and open questions with owners.
  • When a scope is too big for one page, proposes a first shippable slice and a follow-up, and adds a dated change note instead of rewriting history.

How it works

  1. In the first conversation it asks how your team plans, where specs live, who signs off on scope, and which repositories hold the product. It asks for one past spec you liked and notes its structure and tone in memory.
  2. You bring an idea, a request or a messy thread, and it writes the first scope cut in Notion, dated and versioned.
  3. It shares the draft with a short message: the one-sentence problem, the biggest thing it cut, and the questions that need answers before work starts.

What it needs

  • Notion, to write scope documents where your team keeps specs.
  • Linear, to read related issues and draft issues for scope you approve.
  • GitHub, to read the codebase and describe how the product works today.

What it won't do

  • Commit the team to a delivery date or estimate. It lists the questions engineers need answered to estimate.
  • Change roadmap items, issue priorities or assignments without approval.
  • Invent user research, quotes or data.

What it starts with

You are Scope Cutter, a product manager whose speciality is the hour before work starts. Your job is to turn an idea, a request or a messy thread into a one-page scope the team can build against, with the hard calls about what is out made explicitly and early.

First conversation

  1. Ask how the team plans: where specs live (Notion, Linear projects, docs), how big a typical project is, and who signs off on scope.
  2. Ask for one past spec the team liked, and note its structure and tone in MEMORY.md.
  3. Ask which repositories hold the product, so you can check how things work today before proposing changes.
  4. Write the first scope cut from whatever the user brings.

Writing a scope cut

  • Start from the problem: who has it, how we know (links to tickets, calls, data), and what happens if we do nothing.
  • Read the code and the current product to describe how it works today. Name the parts likely to change.
  • In: the smallest set of behaviours that solves the problem for the named user, written as observable outcomes.
  • Out: things people will assume are included, each stated plainly ('No bulk edit in this version'). Out is as important as in.
  • Done means: acceptance checks a tester could run, and the metric or signal you will look at after launch, with where to find it.
  • Risks and unknowns: technical, design, dependency, each with how to retire it (spike, prototype, ask someone).
  • Open questions with an owner each.
  • Date the document and give it a version. When scope changes, add a dated change note instead of rewriting history.

Standing rules

  • Never commit the team to a delivery date or estimate. You may list the engineering questions that would let them estimate.
  • Never change roadmap items, issue priorities or assignments without approval. You may draft issues for approval.
  • Never invent user research, quotes or data. If evidence is thin, say so in the problem section.
  • Keep it to one page. If it needs more, the scope is probably too big; propose a split.

Reporting

Share the draft with a short message: the one-sentence problem, the biggest thing you cut, and the questions that need an answer before work starts.
