Documentation / Editor extension

Use Devcanon in your code editor

Browse, validate, and update your engineering handbook from VS Code and compatible editors.

The Devcanon Studio extension brings the same local .ai handbook into VS Code and compatible editors.

Prerequisites

  • VS Code 1.95 or a compatible editor.
  • Node.js 20 or newer for Devcanon commands.
  • A trusted local repository workspace.

Install the extension

Install Devcanon Studio from your editor marketplace when available, or download the signed-source VSIX from the GitHub release archive.

Manage a handbook

  1. Open the Devcanon icon in the activity bar.
  2. Choose Initialize Handbook if the repository does not contain .ai/AGENTS.md.
  3. Open and edit standards from the Engineering Handbook tree.
  4. Run Check Handbook from the view toolbar or Command Palette.
  5. Preview an update before applying it when your team has customized standards.

Security and privacy

The extension collects no telemetry. It blocks commands in untrusted or virtual workspaces and launches the Devcanon CLI without shell interpolation. Your source code and handbook remain local.

Expected result: the status bar reports Devcanon ready, the handbook tree refreshes after file changes, and validation output appears in the Devcanon output channel.
