By danielrosehill

Define hardware project BOMs with ESP32-first focus — onboarding captures location/vendors/on-hand gear, then skills for spec creation, budgeting, sourcing, compatibility checks, wiring specs, assembly instructions, 3D-printable suggestions, and AI-generated mockups.

bom-from-project-idea

/bom-from-project-idea

Start from a free-form project description and work backwards to a candidate BOM. Lighter-weight than create-hardware-spec — used when the user wants a quick parts list to evaluate feasibility before committing to a full spec.

check-inventory

/check-inventory

Query a user-defined MCP-connected inventory system to check live stock for a project's BOM. Use this when the user has a real inventory backend (warehouse management system, parts database, home-lab inventory) wired up via MCP, rather than a static on-hand list.

check-onhand-coverage

/check-onhand-coverage

Diff a project's BOM against the user's local on-hand inventory (the free-form list captured during onboarding). Reports which parts are already available, which need to be ordered, and which have plausible substitutes on hand.

compatibility-check

/compatibility-check

Sanity-check the parts in a BOM against each other — voltage levels, logic-level compatibility, current draw vs. regulator capacity, I2C address conflicts, shared bus contention, and pin count adequacy on the chosen MCU. Flags issues before the user orders.

create-assembly-instructions

/create-assembly-instructions

Generate step-by-step assembly instructions for a project — the order in which to wire/solder/mount parts, test gates between steps, and common gotchas. Reads the BOM, wiring spec, and datasheet quirks; writes a build guide the user can follow on the bench.

Hardware Spec Assembly

A Claude Code plugin for defining BOMs and assembly plans for hardware projects, with first-class support for ESP32-based builds.

The plugin walks the user from a project idea to a written spec, a structured BOM, a budget, a sourcing plan, compatibility checks, wiring spec, assembly instructions, 3D-printable suggestions, and AI-generated mockups.

Skills

Skill	Purpose
`onboard`	First-run setup — captures location, vendors, project domains, on-hand gear, optional MCP-connected inventory.
`create-hardware-spec`	Build a structured spec + BOM for a new project.
`bom-from-project-idea`	Lightweight: free-form idea → draft BOM, no project files written.
`generate-budget-approximation`	Cost envelope (low/mid/high) per sourcing strategy.
`suggest-sourcing-options`	Per-vendor consolidated cart plan, with authenticity flags.
`check-onhand-coverage`	Diff BOM against the static on-hand list captured during onboarding.
`check-inventory`	Diff BOM against a live MCP-connected inventory system.
`datasheet-lookup`	Fetch and summarise official datasheets; cache locally.
`compatibility-check`	Voltage / logic-level / I2C address / pin count sanity checks.
`generate-wiring-diagram-spec`	Pin map, bus topology, power distribution, breadboard notes.
`create-assembly-instructions`	Ordered build steps with test gates between them.
`suggest-3d-printables`	Enclosures, mounts, brackets — existing models or custom specs.
`export-bom-csv`	CSV + clean markdown table export of the BOM.
`generate-mockups`	AI-generated visualisations via fal.ai nano-banana.

Data storage

Plugin config and caches: ${CLAUDE_USER_DATA:-${XDG_DATA_HOME:-$HOME/.local/share}/claude-plugins}/hardware-spec-assembly/
User-owned project files (specs, BOMs, mockups): a directory chosen during onboarding (default suggestion ~/Documents/Hardware-Projects/).

Installation

claude plugins install hardware-spec-assembly@danielrosehill

Then run the onboard skill.
