01-minimal

01 — Minimal baseline

Demonstrates: a single active settings layer, catalog cross-reference in the drawer, and clean "everything else is unset" rendering.

Run Claude command

claude

No env vars, no CLI flags — only .claude/settings.json is in play.

Alternate — re-run with one env var set to demonstrate env-layer shadowing on the same scenario without changing any files:

CLAUDE_CODE_DISABLE_GIT_INSTRUCTIONS=1 claude

CLAUDE_CODE_DISABLE_GIT_INSTRUCTIONS=1 projects through catalog/env-settings-map.json as includeGitInstructions: false, shadowing the true set in .claude/settings.json. Attach knobs.cc to this claude and the includeGitInstructions row source flips from PROJ to ENV, with the project value shown shadowed in the layer waterfall.

What's set

.claude/settings.json defines three top-level keys:

• model: "sonnet"
• effortLevel: "medium"
• includeGitInstructions: true

That's it — no local override, no env block, no permissions.

How to demo

1. Open knobs.cc.
2. SessionPill → "Choose a project directory" → pick tests/01-minimal/. (No need to start claude — pure file-based read.)
3. Look at the PRECEDENCE STACK rail on the left:
   • project row shows count 3, status dot active.
   • Every other layer shows count 0, dimmed.
4. In the settings list, click model:
   • Drawer opens with the value ("sonnet"), provenance chip (project), and the catalog description / type / default pulled from upstream docs.

Talking points

• The catalog cross-reference is what makes the drawer useful — every setting links back to its documented purpose and default.
• Layers with no contribution are still visible in the rail so users know the precedence order at a glance, not just what's active.
• The alternate command is a one-keystroke way to show env-layer shadowing without leaving the scenario: same files, same drawer cross-ref, but the source chip flips and the waterfall lights up. Great as a "...and now watch this" moment.
