Crush v0.88.0

Fri, 31 Jul 2026 21:07:20 GMT

Crush v0.88.0 adds `.crushrc` bash-based config, `permissions deny`, AWS Bedrock SSO re-auth, and new crushrc builtins for providers, models, MCPs, LSPs, and hooks. • Adds `.crushrc` bash-based configuration file, replacing JSON config with a scriptable shell format that supports conditionals, `source` includes, and environment variable expansion. • Adds `permissions deny` command in crushrc to explicitly hide specific tools from the agent. • Adds `permissions allow` command in crushrc to auto-approve tools without prompting. • Adds `provider add` and `model add` crushrc builtins for registering custom providers and models (e.g. local Ollama instances). • Adds `mcp add` / `mcp remove` crushrc builtins for managing MCP servers directly from the shell config. • Adds `lsp add` / `lsp remove` crushrc builtins for managing LSP servers from crushrc. • Adds `hook add` / `hook remove` crushrc builtins for managing agent hooks from crushrc. • Adds `option reset` command to wipe list-type shell config options back to defaults. • Exposes `CRUSH_VERSION` environment variable inside crushrc scripts for version-conditional configuration. • Adds automatic re-authentication UX for AWS Bedrock SSO token expiry, with automatic turn retry after re-auth. • Supports building and running Crush on illumos (OpenIndiana, OmniOS). • Applies top-level environment variables from crushrc on startup.
