odin-native

Odin Native

Semantic Odin tools for Codex, backed by ols, odin, and odinfmt.

This plugin exposes a local MCP server that gives Codex token-efficient Odin code intelligence without relying on text search alone. It starts ols per project root for semantic LSP queries and shells out to Odin command-line tools for checks, tests, builds, vet diagnostics, and formatting previews.

Features

• ols hover, definitions, references, document symbols, workspace symbols, diagnostics, and code actions.
• odin check with JSON errors.
• Vet-style Odin checks.
• odin test and odin build.
• Non-mutating odinfmt preview.
• Lightweight --selftest fixture for smoke testing the MCP server.

Requirements

• Python 3.11 or newer.
• odin on PATH.
• ols on PATH.
• odinfmt on PATH.

Installation

Place this directory at:

%USERPROFILE%\.codex\plugins\odin-native

The plugin metadata is in .codex-plugin/plugin.json, and the MCP server command is in .mcp.json.

Smoke Test

Run from the plugin root:

python scripts\odin_native_mcp.py --selftest

Expected result: JSON output with "ok": true.

Tooling Notes

• LSP positions use 1-based line and 1-based character inputs.
• Call odin_lsp_diagnostics before odin_lsp_code_actions when asking for quick fixes on a problematic range.
• Use odin_format_preview for formatting checks; it does not rewrite files.
