ki-stack-schematic

ki-stack-schematic is a skill for Claude Code from Milind220/Ki-Stack. It costs 52 tokens per session (1,107 once invoked), scanned A, original, MIT.

A workflow for KiCad schematic projects, including sheet rendering and electrical-rule checking. A schematic is the diagram that shows how electronic components connect before a circuit board is made.

In plain words
What is it for?
Use it to find and inspect schematic files, render sheets, run ERC checks, manage project text variables, and verify schematic edits.
Why use it?
It combines schematic inspection and checks so design changes can be reviewed visually and tested for electrical mistakes.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

ki-stack-schematic scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Purpose

This Phase 2 domain skill orchestrates schematic-focused work by composing:

  • ki-stack-render
  • ki-stack-file-surgery
  • ki-stack-verify
  • ki-stack-live when schematic-side IPC support is relevant in the environment

Use this skill when the user's intent is clearly about schematics rather than boards.

What it covers

  • rendering schematic sheets and full schematics
  • schematic ERC
  • project text variable workflows
  • schematic file discovery and inspection
  • proof-oriented schematic change verification

Routing rules

Use ki-stack-render when

  • the user wants to see a schematic page or export it
  • the task is primarily visual
  • the goal is proof, documentation, or comparison

Use ki-stack-file-surgery when

  • the schematic-side task is a deterministic file transformation
  • the task is project-file or metadata oriented
  • no live editor context is required

Use ki-stack-live when

  • the environment exposes the needed schematic-side API surface
  • the task genuinely benefits from live project/editor state

Use ki-stack-verify after

  • schematic changes that could affect electrical correctness
  • any schematic edit that needs before/after proof

Phase 1: Orient

  1. Confirm the task is schematic-scoped.

  2. Identify the relevant .kicad_sch and .kicad_pro files.

  3. Probe the environment:

    skills/ki-stack/bin/kicad-version
    skills/ki-stack/bin/kicad-project-find <root>
    
  4. Decide the path:

  • render-only
  • offline file/proj transform
  • live API path if the environment supports it

Phase 2: Inspect

For schematic tasks, inspect the available files and identify page scope before editing.

Helpful checks:

skills/ki-stack/bin/kicad-project-find <root>

For project-side text variables, the kicad-python project object exposes:

  • get_text_variables()
  • set_text_variables()
  • expand_text_variables()

If the task is visual, render a baseline artifact first.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
