Your coding agent moves fast. Brief keeps it from moving in the wrong direction.

Brief gives Cursor, Claude Code, Windsurf, and VS Code the decisions your team has already made. It catches conflicts before they turn into PR churn and rework.

Example: Brief catches a plausible wrong turn while the agent is building, not in review.

Coding agents follow product context better when they actually have it.

Our research found that product context improved AI coding-agent decision compliance from 46% to 95%, a 49-point gain.

Read the paper

Your codebase is not your product context.

Your agent can read the codebase, but it does not automatically know:

  • which implementation approaches were explicitly ruled out No custom JWT auth.
  • why a product decision was made Supabase Auth keeps SSO a later step, not a rewrite.
  • what is changing this quarter versus later Now: email sign-in. Later: SSO.
  • which constraints matter for this feature Sessions go through the existing middleware.

How Brief works

  1. Capture decisions

    Product, engineering, and customer context lives in Brief instead of disappearing across Slack, docs, and old PRs.

  2. Give agents the context

    Brief makes relevant decisions and constraints available in the IDE while the agent is building.

  3. Catch conflicts before rework

    Before auth, database, API, or dependency changes, the agent checks its approach with Brief. If it conflicts with a team decision, Brief flags it before it becomes a review cycle.

Catch wrong turns while building, not in review.

Without Brief

Caught in review
  1. Agent chooses a plausible implementation based on codebase patterns or training data.
  2. Team catches the mismatch in review.
  3. Work gets redone.

With Brief

Caught while building
  1. Agent sees the relevant decision while building.
  2. It chooses the aligned path or gets flagged before the PR.

Working with AI felt like playing telephone. I'd describe what I needed, the AI would build something technically correct, but also wrong. Brief keeps the AI connected to our product, so I get what I actually wanted.
