SemLang Packages

This public repository contains SemLang package resources for agent tools while SemLang core source remains private in Unsupervisedcom/semlang-core.

Public SemLang documentation lives in docs/, supplementary design notes live in design-docs/, and shared documentation/test examples live in examples/. The private core repository consumes these examples directly from this public package checkout so the examples used in docs and tests stay in one place.

The skills/ directory is generated from the authoritative skills_for_cli_packages/ directory in semlang-core during core releases.

Pi

Install the Pi package from this repository:

pi install git:https://github.com/Unsupervisedcom/semlang

For local development from a semlang-core checkout that has this repository as a submodule:

pi install "$PWD/packages/semlang"

The package explicitly loads the bundled pi-mcp-adapter extension from node_modules/pi-mcp-adapter/index.ts. The Pi package exposes all SemLang skills in skills/, including semlang-setup, semlang, and initial-ontology-creation.

Use the semlang-setup skill to inspect or add SemLang MCP configuration. After MCP config changes, run /reload or restart Pi.

Claude Code

This repository includes the Claude Code plugin manifest in .claude-plugin/plugin.json, an MCP server config in .mcp.json, and SemLang skills in skills/.

After adding the public SemLang package repository to a Claude Code plugin marketplace, install it with:

claude plugin install semlang@semlang

If your marketplace entry uses a different marketplace name, replace the final semlang after @ with that name.

SemLang MCP starts with the published SemLang package, pinned to this package version, for example npx -y [email protected] mcp.

SemLang MCP respects SEMLANG_* environment settings. Run semlang setup to inspect resolved SemLang project settings.
