Zsh for Claude Code. PTY mode lets Claude type passwords. NEVERHANG + A.L.A.N.
Zsh for Claude Code. PTY mode lets Claude type passwords. NEVERHANG + A.L.A.N.
Zsh execution tool for Claude Code with full Bash parity, yield-based oversight, PTY mode, NEVERHANG circuit breaker, and A.L.A.N. short-term learning.
The toolset is worth reading before you wire it up, because it tells you what the integration is really for:
zsh — Execute command with yield-based oversightzsh_poll — Get new output (delta) from running task with line numberszsh_send — Send input to task's stdinzsh_kill — Kill a running taskzsh_tasks — List all active taskszsh_health — Overall health statuszsh_alan_stats — A.L.A.N. database statisticszsh_alan_query — Query pattern insights for a commandzsh_neverhang_status — Circuit breaker statezsh_neverhang_reset — Reset circuit to CLOSEDInstallation goes through your MCP client rather than a global install: point it at required on PyPI and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.
Configuration is passed through the environment: NEVERHANG_TIMEOUT_DEFAULT, NEVERHANG_TIMEOUT_MAX, ALAN_DB_PATH. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
Among the planning and project tracking options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Zsh's toolset — zsh, zsh_poll, zsh_send and 7 more — is a fair guide to whether it matches your workflow. It is maintained by ArkTechNWA; worth a glance at recent repository activity before you build anything load-bearing on it.
