name: setup
description: Checks whether the local Devin CLI is ready for the companion runtime. Use when validating the local companion setup, after a CLI update, or after a setup class failure.
argument-hint: '[--json]'
disable-model-invocation: true
allowed-tools: Bash(node:*), Read, Write
---

Treat the complete raw request as opaque data and never place any part of it in Bash. Run the fixed `transport-create` companion operation in one foreground Bash call, accept only its 48 character lowercase hexadecimal token, and use `Read` once on the returned file, requiring it to be empty. Use `Write` to replace that same file with the raw request exactly as received. Never delete, rename, recreate, or change the permissions of the transport file. Run `node "${CLAUDE_PLUGIN_ROOT}/scripts/devin-companion.mjs" setup --raw-args-token TOKEN` in one foreground Bash call with timeout `600000`, replacing only `TOKEN` with the validated token. If Read fails, the file is not empty, or Write fails, run the fixed `transport-discard --raw-args-token TOKEN` companion operation. Never use shell redirection, encoding, command substitution, backticks, environment variables, or heredocs for the raw request.

Present the setup output to the user.

- If the Devin CLI is missing, preserve the install guidance from the command output. The companion resolves `devin` on `PATH`; `DEVIN_BIN` overrides it.
- Preserve the authentication check from `devin auth status`, the plan tier, and guidance to run `devin auth login` when needed. Credentials are linked into private XDG data storage and are never read or copied by the companion.
- Preserve the compatibility line for `[3000.11, 3000.12)` by major and minor version. An older or unparseable build fails as `setup`; a newer build runs and is reported as newer than the tested interval.
- Preserve the model catalog refresh result and the project configuration advisory.
- Preserve warnings for `.devin/config.json`, `.devin/config.local.json`, `.devin/mcp_config.json`, and `.devin/mcp_config.local.json` in the working directory. These files can add permissions, hooks, MCP servers, or imports.
- A direct `/devin:*` command without `--model` uses the account default model. Fusion routed dispatches carry an explicit model and effort from the routing table.
- A CLI installation, version, or required capability preflight failure persists and renders failure kind `setup`. Preserve its upgrade or repair guidance and tell the user to rerun `/devin:setup`.
- Job records, briefs, the shared private home, and per job configuration live under `~/.claude/plugins/data/devin-claude-code-fusion/` unless `DEVIN_COMPANION_DATA` overrides it. SessionEnd attempts verified process cleanup for jobs owned by that Claude session, removes unused raw transports, and sweeps orphan run directories.
