life-as-code Lens

Feature provenance, inline in your editor.

See which feature owns the file you're editing, check its status and completeness, and jump straight to its feature.json — without leaving VS Code.

Hover preview

What it does

Code lens — appears above the first line of every file inside a feature folder. Shows the feature key, status icon, and completeness score at a glance.

Hover — hover over any featureKey string (e.g. "feat-2026-007") anywhere in your codebase to see the full feature summary inline.

Status bar — a chip in the bottom bar shows which feature owns your current file. Click it to open feature.json.

Right-click → lac: Open feature.json — jumps directly to the feature record for the file you're editing.

Diagnostics — squiggles on malformed feature.json files with inline validation messages.

Requirements

Install the CLI first — it ships with the lac-lsp server the extension uses:

npm install -g @majeanson/lac

Then initialise a workspace in your repo:

lac workspace init

LSP mode (richer features)

By default the extension runs in lightweight mode. Enable LSP mode for full hover, diagnostics, and workspace symbol search:

// .vscode/settings.json
{
  "lacLens.lspMode": true
}

lac-lsp is already on your PATH after installing @majeanson/lac — no extra install needed.
