Wire Lang

Wire Lang Authoring Skill

Use this skill to help people author Wire Lang source. Wire Lang is a textual language for describing electronic schematics and rendering them as readable SVG diagrams.

First Move For Authoring

1. Identify the circuit the user wants to describe.
2. Choose component instances and stable instance IDs.
3. Connect terminals through named nets or connect statements.
4. Add title, description, annotations, and render hints only when useful.
5. Check the source with wire check when the CLI is available.

Read the focused reference files as needed:

• references/concept-map.md for the authoring concept graph.
• references/source-format.md for syntax and statement shapes.
• references/component-library.md for standard components, terminals, and properties.
• references/style-guide.md for source-writing conventions.
• references/examples.md for good and bad examples.
• references/boundaries.md when a user asks for simulation, PCB layout, breadboard layout, BOMs, custom symbols, or browser/editor integrations.

Validate And Render

Use the wire CLI instead of hand-validating whenever the user's environment can run it:

npm i -D wire-lang
npx wire check path/to/circuit.wire
npx wire render path/to/circuit.wire --out path/to/circuit.svg
npx wire watch path/to/circuit.wire --out path/to/circuit.svg

For a one-off run without adding a package to the project, invoke the wire binary from the wire-lang package:

npx -p wire-lang wire check path/to/circuit.wire
npx -p wire-lang wire render path/to/circuit.wire --out path/to/circuit.svg

• Use wire check as the real implementation of checking the source against MVP syntax and the component library.
• Use wire render <file>.wire --out <file>.svg as the canonical author-to-SVG artifact step.
• Use wire watch <file>.wire --out <file>.svg while iterating.
• Add --json to wire check, wire render, or wire watch when machine-readable diagnostics are useful.
• For Markdown or MDX, default to @wire-lang/browser and initialize it after HTML is ready. For ahead-of-time rendering, use @wire-lang/markdown with { mode: "static" }. See references/markdown.md for setup. On hosts without either integration, run wire render and embed the generated .svg.
• Do not claim that source was checked or rendered unless the command actually ran. If the CLI is unavailable, say the source is not tool-validated and give the exact command to run.

Authoring Rules

• Start every MVP source with schematic.
• Use .wire source to describe logical schematics, not breadboards, PCB layouts, physical routing, or simulations.
• Declare component instances with component ID Type ....
• Use canonical component names and terminal names from the standard library.
• Use named nets for important or reused electrical nodes such as VCC, 5V, 3V3, GND, SDA, or SCL.
• Use connect for simple anonymous connections.
• Treat power nets as normal nets; they do not create hidden connections.
• Use annotation for visible explanatory text. Use // only for source comments.
• Use render hints for layout guidance, not electrical meaning.
• Do not invent unsupported syntax. If Wire Lang cannot express the user's request in the MVP, say so and offer the closest valid source.

Default Output

When asked to create Wire Lang source, return a complete .wire block:

schematic
  title "..."
  description "..."

  component ...

  net ...
  connect ...

After the block, include a short note only for important assumptions, such as component choices or unsupported requested behavior.

When the user asks for an image or SVG artifact, include the wire render command to produce it. If you ran the command successfully, include the output path; otherwise, state that rendering has not been tool-verified.

Common Corrections

• "Draw a wire from X to Y" usually means create a connect statement or named net; do not encode visual paths.
• "Show this note in the diagram" means use annotation, not //.
• "Ground everything" still requires explicit GND net connections.
• "Make this vertical" is a render hint, not a component property.
• "Arduino board" is outside the MVP standard library; model it as a local module-style component if needed.
• "Chip with numbered pins" is the IC type: pins=[1:VCC@left, 2:GND@left, 3:OUT@right]. Connect pins by name.
• "Leave this pin unused / N.C." is a no-connect TERMINAL statement, not a floating net.
• "Mark the 3V3 rail" can use a PowerFlag name=3V3; it is a visual flag, not a hidden global net.
• Crossings without a junction are left simply overlapping by default; "draw a hop where lines cross" is render crossings=hop.

Keep This Skill Current

When the Wire Lang syntax, examples, standard component library, or MVP authoring rules change, update this skill and the focused reference files.

Before finishing an authoring response, check:

• The source starts with schematic.
• Component types and terminal names exist in the standard library or in a local component definition.
• Power nets are explicitly connected.
• Visible explanatory text uses annotation, not //.
• Render hints do not carry electrical meaning.
• Unsupported requests are called out with the closest valid MVP expression.
