gsd-reasonix — GSD for Reasonix (EoS host integration)

Repo: https://github.com/onionviolet/gsd-reasonix
Release: https://github.com/onionviolet/gsd-reasonix/releases/tag/v1.0.0
License: MIT · protocolVersion: 1 · enginesGsd: >=1.10.0

Reasonix is a Go, single-static-binary, DeepSeek-native terminal coding agent. This integration renders the GSD workflow set as native Reasonix slash-command launchers. GSD workflows are not reimplemented: they stay in ~/.claude/gsd-core/workflows/, and each launcher maps their host-neutral instructions onto Reasonix's own tools (task / fleet for subagents, ask for questions, todo_write for plans, complete_step for evidence-backed sign-off).

Declared axes

Every value below is sourced from Reasonix's own documentation (docs/SPEC.md, docs/GUIDE.md, docs/CONFIG_PATHS.md, CONTRIBUTING.md), per the "never infer" rule.

Axis	Value
embeddingMode	declarative
commandSurface	slash-file
modelMode	passive
hookBus	host
stateIO	filesystem
transport	mcp
runtime	go

interfacePoints: command, artifact. profile: declarative-cli.

effortSurface is deliberately omitted. Reasonix resolves effort from config (supported_efforts / default_effort) and the /effort command, with no argv route, so neither argv nor none is a documented fit and the field is optional.

Known limitation, stated up front

Reasonix's docs do not state its subagent toolkit or whether a background-dispatched subagent may spawn further subagents. Under shouldFlattenDispatch that fails closed, so the orchestrator runs inline rather than backgrounded. That is the correct conservative outcome given the documentation, not a bug. Getting it lifted means an upstream documentation change in Reasonix itself, and I will revise the entry if that lands.

Install

npm install --global github:onionviolet/gsd-reasonix
gsd-reasonix install

Uninstall removes only the launchers the package ships, and removes its [skills] excluded_paths line only when it is still the one the installer wrote. Hand-written gsd-* skills and user-edited config values are left in place. npm test runs 14 checks over the launcher set and the install round-trip against a throwaway REASONIX_HOME.

Context

This supersedes #3346, which proposed an in-tree capabilities/reasonix/capability.json and was correctly closed as filed against the wrong surface. Per ADR-1239 this ships as an out-of-tree host-plugin listed in the EoS Registry. Registry PR to follow.
