aowlcode — Nim/Nimony Claude Code plugin & MCP server
Mediates agent access to the Nim and Nimony toolchains through structured MCP tools: an agent works from compact diagnostics, outlines, and targeted NIF slices instead of raw compiler output and multi-hundred-kilobyte S-expression artifacts. One interface, both toolchains — the same commands and tools resolve to nim/nimsuggest/nimble or to nimony/nimsem/hastur (auto-detected per project, overridable).
Install
text
/plugin marketplace add aoughwl/aowlcode
/plugin install aowlcode@aowlcodeaowlcode@aowlcode is <plugin>@<marketplace> — the repo is its own marketplace. Enabling the plugin registers the nimlang MCP server, activates all hooks, and exposes /aowlcode:* commands (see /help).

| Page | Covers |
|---|---|
| Tools | Every nimlang MCP tool — args, return shape, one-line purpose. The full reference. |
| Commands | /aowlcode:* slash commands, each mapped to its backing tool. |
| Agents | Subagents (nif-inspector, nim-fixer, nim-applier), model tiering, and the fanout-apply workflow. |
| Execution | trace / debug — running and inspecting a program via the aowli interpreter, not just compiling it. |
| Internals | Skills, hooks, LSP dispatch, config env vars. |

Toolchain detection
toolchain="auto" (the default) walks up from the target file for a nimony.paths/nimony.cfg, or a nim.cfg mentioning nimony → Nimony; otherwise Nim. NIMLANG_TOOLCHAIN=nim|nimony forces it globally; an explicit toolchain arg wins per call. nimony c exits 0 on failure — every tool computes ok from parsing for an Error: diagnostic, never the exit code.
