Claude Code Skill

Claude Code Skill: eplan-development

While the MCP server (this whole wiki) lets Claude act on EPLAN, the eplan-development skill teaches Claude to write correct EPLAN code: C# scripting, the EPLAN API (parts database, properties), and Remote Client automation — including headless EPLAN and Cogineer. Distilled from working production code, with the pitfalls that actually bite.

It automatically loads whenever you ask Claude to write EPLAN scripts, call EPLAN actions, access the parts database, or build apps that drive EPLAN remotely — and it instructs Claude to verify action names/parameters against the docs RAGs instead of guessing (2027/FTS5 first for exact names, 2026/semantic as fallback).

Install

/plugin marketplace add covagashi/eplan-rag-mcp
/plugin install eplan-development@eplan-tools

Update later with /plugin marketplace update eplan-tools. Or copy the folder manually into ~/.claude/skills/eplan-development (personal) or <project>/.claude/skills/eplan-development — see the skill's own README for exact commands. Invoke explicitly with /eplan-development, or let it trigger automatically on EPLAN-related tasks.

Pairs well with

• This MCP server — the skill teaches Claude to write correct code and avoid the traps; the server lets it execute live.
• Remote Documentation RAGs — the skill tells Claude to consult rag2027 (FTS5) first for exact action/parameter names, rag2026 (semantic) when the query shares no vocabulary with the docs at all.

Coverage

EPLAN Electric P8 2022–2025, with version-specific notes: ribbon API since 2022, remoting default-on in 2023 vs "Remote Client Access" + gRPC in 2025, .NET Framework 4.8.1 targeting.
