What it does

Wired Subcircuit Design is an agent skill from oaslananka/kicad-mcp-pro. Build a genuinely wired, showcase-grade KiCad schematic with KiCad MCP Pro — wired sub-circuit islands plus a tidy label bus — instead of the correct-but-plain by-name-label output of auto layout.

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Agent Workflows, covering MCP servers. It works with Model Context Protocol. The repository describes itself as: MCP server for KiCad, connecting AI agents to schematic and PCB workflows, ERC/DRC validation, DFM checks, BOM analysis, and manufacturing preparation—with controlled edits and… The licence is MIT.

When your agent uses it

  • Tasks that involve MCP servers

Example prompts

  • “/wired-subcircuit-design”

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  1. Anchor the main part (MCU / module) in the center.
  2. Wire the sub-circuit islands. Decoupling, reset, boot-strap, status LED,
  3. Label bus for the breakout. Route general IO to a header with matched local
  4. Conventional power. +3V3 up, GND down; put exactly one PWR_FLAG on
  5. Place each sub-circuit in its own x-column below the anchor, and keep
  6. Fill the title block with sch_set_title_block_info.

What it can do on your machine

Read from SKILL.md and the folder at commit bfbed31. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Wired Subcircuit Design loads about 1.2k tokens when it runs. Until then it costs about 55 tokens; SKILL.md has 643 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~55
When it runs · the whole SKILL.md, loaded when a task matches
~1.2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Wired Sub-circuit Design Skill

Use this skill when an agent must produce a schematic that looks like a person drew it — wired functional blocks, conventional power, a clean breakout bus — not just an electrically valid netlist. It is the deliberate, higher-effort path that sch_build_circuit(auto_layout=True, nets=...) cannot reach.

Specific to oaslananka/kicad-mcp-pro. Keep in sync with docs/tools-reference.generated.md. Worked reference: examples/gallery/esp32-c3-wroom-02-breakout.

Why auto layout is not enough

sch_build_circuit with nets uses a collision-safe terminal strategy: every pin endpoint gets a stub plus a same-named global label / power symbol, so nets connect by name and can never short by crossing geometry. That is correct and ERC-clean, but it reads as a machine netlist: every decoupling cap floats between its own +3V3 and GND labels instead of being wired. Showcase quality needs explicit placement and wires. The cosmetic score never measures this — judge the render, not the number.

The one rule that avoids a blank sheet

Build the whole sheet in a single sch_build_circuit pass with explicit symbols (with coordinates), wires, labels and power_symbols — and no nets, no auto_layout. Do not assemble a schematic from scratch with repeated sch_add_symbol calls: a freshly seeded sheet has no root UUID that the reader round-trips, so each incremental add stamps a different instance path and KiCad renders a blank sheet even though the file parses. One pass writes one consistent root UUID, so every symbol lands on the root sheet.

Compute exact pin coordinates up front with get_pin_positions(lib, sym, x, y, rot) (pure geometry — no placement needed), then wire pin-tip to pin-tip.

Design pattern

  1. Anchor the main part (MCU / module) in the center.
  2. Wire the sub-circuit islands. Decoupling, reset, boot-strap, status LED, regulators — draw each as a real wired block ending in power symbols. This is what separates a showcase from auto output; do not let these become floating labelled pins.
  3. Label bus for the breakout. Route general IO to a header with matched local labels. Generate the part-side and header-side labels from one source list so the two label sets are identical by construction — this eliminates the whole isolated_pin_label / label_dangling class, not just the ones you happen to see.
  4. Conventional power. +3V3 up, GND down; put exactly one PWR_FLAG on each supply net so ERC sees the rails driven.
  5. Place each sub-circuit in its own x-column below the anchor, and keep decoupling clear of the anchor's stub fan — most first-pass ERC errors (multiple_net_names) come from a power symbol landing on a neighbouring label.
  6. Fill the title block with sch_set_title_block_info.

Attach labels correctly

A net label must sit on a wire endpoint. When tapping a sub-circuit node, add a short stub wire and place the label at the stub's free end — a label floating beside a wire raises label_dangling.

The loop

  1. Plan all coordinates from get_pin_positions; assemble the four lists.
  2. Build in one sch_build_circuit pass.
  3. Guard with ERC. Run run_erc. Fix every violation before judging looks — a blank/oddly-passing ERC means KiCad isn't reading your symbols (see the root UUID rule).
  4. See. Render with sch_render_png (or kicad-cli sch export svg) and judge against the rubric below. The render is ground truth.
  5. Refine placement for overlaps and composition; rebuild. Stop when ERC is clean and nothing overlaps — do not chase the cosmetic score past that.

Rubric — what "wired showcase" looks like

  • Functional blocks are wired, not floating labelled pins.
  • Power symbols are conventional; one PWR_FLAG per supply.
  • The breakout bus is tidy and every label is matched (no isolated labels).
  • Orthogonal wiring, on-grid, no diagonal runs, no overlapping graphics.
  • Complete title block; content composed rather than crammed in one corner.

Guardrails

  • Wired ≠ correct-by-magic. Finish with run_erc; a showcase must also be clean.
  • Prefer the label bus over routed nets wires (unsafe_routed_wires=True can short by crossing geometry — avoid it).
  • One curated example is worth more than a bulk auto-generated gallery; expect per-example effort.
