easyeda-copilot

easyeda-copilot is a skill for Claude Code, Codex from biosshot/easyeda-copilot. It costs 44 tokens per session (2,330 once invoked), scanned A, original, MIT.

A guide for using EasyEDA Copilot MCP tools to design electronic circuits and circuit boards. EasyEDA is software for creating schematics and printed circuit boards, while MCP connects those tools to an assistant.

In plain words
What is it for?
Creating or modifying schematics, placing PCB components, preparing assemblies, previewing boards, checking design-rule violations, and routing boards.
Why use it?
It helps follow the required rules for component placement, board checks, previews, assembly, and routing without relying on undocumented tool behavior.

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

easyeda-copilot 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 4d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (datasheets/scripts/common.mjs, datasheets/scripts/download.mjs, datasheets/scripts/pdf-outline.mjs), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 70 lines — stays where its author put it; the contents beside it link to each section on GitHub.

EasyEDA Copilot

Use the standalone CLI skill when it is available, even if direct MCP tools are also connected. Use direct MCP tools when the skill is unavailable or the user explicitly requests MCP. Both expose the same tools and JSON Schemas.

Reuse an existing generated or installed skill; do not rebuild it for each task. It contains build-info.json and scripts/easyeda-copilot-cli.js. Read the CLI guide, resolve the existing launcher's absolute path, and run it with Node.js >=20.19. Before first use, read build-info.json: an npm distribution requires npm install --omit=dev in scripts/runtime/ only if its dependencies have not been installed, while a matching-platform bundled distribution needs no dependency installation. Stop if installationBlockers is nonempty. Build only when no usable skill exists or when updating it from changed source or to a new version; see installation and updates.

In CLI mode, run node <absolute-launcher-path> start once, retain the returned four-character daemon ID, and translate each tool invocation below to <launcher> <id> call <tool>. Omitted arguments are {}; use <id> tools help <tool> for the current JSON Schema rather than inferring arguments. Keep the same ID for a task and its long operations, then stop it when finished.

Complete only the stage requested by the user. A schematic task does not authorize PCB work; placement does not authorize routing.

For overall schematic organization, PCB placement and routing, start with Copilot's dedicated tools and verify their result. Improve that result with scoped refinement; use native API edits when a direct local correction is clearly simpler, the DSL cannot express it, or attempts have stalled. For a self-contained edit inside EasyEDA, use execute_js. When refinement needs local Python/Node.js geometry, libraries or repeated read–calculate–apply cycles, prefer the local SDK so calculations and API calls stay in one script. Reassess this choice when local computation enters an existing MCP workflow. Use a different approach when the user explicitly requests it. Native API access does not expand the authorized task.

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.
