Use every registered Claude Code and Codex subscription as one randomized failover pool in Smithers workflows, so rate limits on a single account never stall a run.

Smithers fallback agents

Smithers keeps a global account registry at ~/.smithers/accounts.json (managed by smithers agents ...). Each subscription account owns an isolated CLI config directory (default ~/.smithers/accounts/<label>), so one machine can hold many Claude Code and Codex logins side by side: Claude Code reads CLAUDE_CONFIG_DIR, Codex reads CODEX_HOME, and Smithers sets the right variable per spawned agent.

fallbackAgents() (exported from smthrs) turns that registry into a failover chain for a <Task>:

One agent per registered Claude/Codex account. Cached 5-hour and weekly headroom orders healthy accounts first. A seeded shuffle breaks ties.
The Smithers engine already fails over along the chain when a rung is rate-limited. Smithers persists the reset per account and turns a known blocked account into a no-network quota rung until that time. The rung re-checks the clock when invoked, so a chain built once — a generated agents.ts builds its pool at module load — recovers the account after the reset instead of retiring it for the whole process.
The "normal" agent is appended as the last rung, and is returned alone when the registry is missing, empty, or unreadable — a workflow using this helper still runs on machines with no registered accounts (CI, teammates).

Add a new agent account

One command per account; pick any label you like (claude-will, codex-2):

smithers agents add --provider claude-code --label claude-2 --tmux
smithers agents add --provider codex --label codex-3 --tmux

--tmux creates the account's config dir, launches the provider CLI inside a detached tmux session with the config-dir env var set, and prints the attach command (tmux attach -t smithers-login-<label>). Attach, complete the login in the browser it opens, detach with Ctrl-b d. Claude Code is launched as claude auth login --claudeai, which goes straight to the subscription flow (on older CLIs without that subcommand it falls back to the REPL, where you type /login). The command polls for the credential artifact (Claude:
