# 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 against the MVP syntax and component library.

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.

## 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:

```wire
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.

## 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.
- Wire hops are drawn by default where lines cross without a junction; "let
  crossings just overlap" is `render crossings=gap`.

## 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.
