No account required for preview

Try Decreen on your repo

Set up Decreen support in your repository, run /decreen-preview in your coding agent, and get a temporary architecture map from local repo analysis.

Claim the map only if it's useful. Unclaimed previews expire after 7 days.

Set up Decreen locally

Run this from your repository root:

npx -y @decreen/local setup

It is safe to re-run.

This sets up local Decreen support, including:

  • agent skills and slash commands for Cursor, Kilo, and Claude Code
  • /decreen-preview for creating your first temporary map
  • post-claim commands such as /decreen-complete, /decreen-refresh, and /decreen-deepen
  • repo-local Decreen files under .decreen/
  • .gitignore entries for local Decreen runtime output

This does not:

  • upload your source code
  • upload source file contents
  • create or claim a workspace
  • log you in
  • install the local analysis runtime
  • configure MCP in your IDE

Then, in your coding agent, run: /decreen-preview

Prefer preview-only manual setup?

You can paste the Decreen Preview skill directly into your coding agent — no npm command required.

Use this path if you want to inspect the skill first, avoid local setup, or use an agent that does not support Decreen's installer yet.

Manual skill locations

  • Cursor: .cursor/skills/decreen-preview/SKILL.md
  • Claude Code: .claude/skills/decreen-preview/SKILL.md
  • Kilo Code: .kilo/skills/decreen-preview/SKILL.md
  • Kilo slash commands also live under: .kilo/command/
  • Other agents: paste the full skill text into your agent instructions.

For complete, refresh, deepen, and status after you claim a workspace, run: npx -y @decreen/local setup

How it works

  1. 1Your coding agent reads your local repository on your machine.
  2. 2It generates a structured architecture artifact.
  3. 3Decreen turns that artifact into a temporary interactive map.
  4. 4You get a preview link.
  5. 5You sign in only if you want to claim, deepen, or refresh the map.

What gets sent?

Your agent sends a generated architecture artifact to Decreen. It may include:

  • systems, containers, and components
  • relationships between them
  • labels and short descriptions
  • containment structure
  • repository metadata, such as branch and commit SHA

It does not send:

  • raw source code
  • source file contents
  • secrets
  • credentials
  • tokens
  • private keys
  • .env values

Local evidence sidecars are written under .decreen/ in your repository and are not uploaded in the preview flow. You can review the generated artifact before upload.
