ballerina-claude-plugins

Ballerina plugin for Claude Code — LSP code intelligence and AI coding assistant in a single plugin.

Plugins

Plugin	Description
ballerina	LSP code intelligence + AI coding skill

Architecture

Plugin design

A single ballerina plugin combines two capabilities:

• LSP — lspServers in plugin.json points to .lsp.json, which starts bal start-language-server and maps .bal files. Provides completions, go-to-definition, hover, and semantic highlighting.
• Skill — skills/ballerina/ contains the ballerina skill for writing, running, and testing Ballerina code.

Both are activated after installing the plugin and restarting Claude Code.

Skill progressive disclosure

Only SKILL.md is loaded when the skill triggers — it is kept intentionally lean (workflow steps only). Reference files are loaded by Claude on demand, keeping context usage low:

File	Loaded when
code-rules.md	Writing or modifying Ballerina code
langlib-reference.md	Looking up built-in language library APIs
setup.md	bal is not found on the machine
