File contents

workbench

Maple (examples/demo-bank) plus whole-graph dev source aliasing plus a dev-only internals pane behind VENDO_WORKBENCH=1 (server env; unset means zero diagnostic parts on the wire). Shipped in PR #1130.

Run

pnpm install && pnpm build       # once — dist must exist; @vendoai/vendo/store stays dist-pinned, so edits there need a rebuild
VENDO_WORKBENCH=1 pnpm --filter demo-bank dev
open http://localhost:3000

Pane docks right: Timeline / Context / Tools / Guard / Raw, plus a turn selector.

Loop

Chat → read the pane → edit packages/*/src (loop.ts, compaction.ts, vendo.ts are the usual suspects — note packages/vendo/src/harnesses/vendo/ is an author-involved zone per its CLAUDE.md) → save → the next message runs the edit. In-flight turns finish on the old code.

Levers

MAPLE_HARNESS=context-e2e — 32k context window, so a few messages reach compaction.
Ask Maple to build something to watch a screen-agent run (tagged, 10-step cap).
The "demo feed" button replays a canned turn for pane-UI work without spending tokens.

Architecture, three lines

Harness sink packages/vendo/src/harnesses/workbench.ts → transient data-vendo-debug parts (never persisted) → ui feed store packages/vendo/src/ui/chrome/workbench-store.ts (20-turn retention) → pane in examples/demo-bank/src/components/vendo/workbench/.

Measuring

After a harness change, pnpm build, then the genbench skill for before/after scores (genbench reads built dists).
