Knowledge factory
Per-device knowledge packs, built offline. Scout researches the device, three Writers structure findings into a graph, rules, and glossary, and an Auditor gates the verdict — APPROVED, NEEDS_REVISION, or REJECTED.

F1 is the prior. Step 1: continuity across F1 — open = blown.

The full demo we submitted to Anthropic for the “Built with Opus 4.7” hackathon — running on the MNT Reform motherboard (CERN-OHL-S, fully open hardware). Two minutes covering the diagnostic agent, the boardview canvas, the schematic compiler, and the live tool-driven workflow.
01 The problem
62 million tonnes of e-waste per year.
Most of it could be repaired.
Independent repair technicians get blocked the moment a fault goes deeper than a screen swap. The references exist — but they live as PDFs nobody indexes, thirteen incompatible boardview formats, and forum threads from 2017 with “did you ever fix this?” at the bottom. No tool reasons over any of it the way a senior tech does.
Wrench Board changes that.

02 The workbench
Four orthogonal workflows. 36 specialized agent tools.
Each workflow is a self-contained surface — composable, scriptable, and exposed to the diagnostic loop as native tools the agent calls directly.
Schematic ingestion
PDF schematics in, ElectricalGraph out. Page-by-page vision pass on Opus 4.7 — natively reasoned, not OCR-flattened — then merged, classified into power / logic / connector edges, and compiled with an inferred boot sequence.
Bench auto-generator
Reads a knowledge pack and proposes simulator scenarios: cause → expected dead rails and components. Five validators gate the output — sanity, grounding, topology, pertinence, dedup — and a per-pack reliability score keeps the agent honest about its causal engine.
Diagnostic agent
Live repair sessions on Anthropic Managed Agents, anti-hallucination on every reply. Four layered memory stores back the agent: cross-device failure patterns and reusable diagnostic playbooks (shared, read-only), the device's own knowledge pack (read-only), and a per-repair scribe notebook (read-write) it reads on resume. Tier-selectable at session open — Haiku, Sonnet, Opus.

03 Tools, in full
36 tools, four workflows, one reasoning loop.
Hover any pill to read what it does. Names lifted straight out of api/agent/manifest.py.
— Read and write the device's knowledge pack and the live repair journal. Refdes lookups validate against the parsed board, never fabricated.

— Drive the live PCB canvas. The agent doesn't describe — it acts: highlights, focuses, dims, draws arrows, proposes stepwise protocols.
