tools

The web-search tool (exposed to the model as web_search) is off until you point it at a search endpoint:

tools {
    web-search {
        enabled #true
        url "https://example.com/search"  // required, must start with http(s)://
        type "ollama"                     // or "to_markdown" (fetch page → markdown)
        headers { Authorization "Bearer $MY_TOKEN" }  // $VAR / ${VAR} expand from the environment
        params type="body-json" {         // or type="query" for GET parameters
            query as="q"                  // tool argument → remote parameter name
        }
    }
}

Default params when omitted: ollama ⇒ POST body with query as="query"; to_markdown ⇒ GET query with query as="q".

shell

shell {
    path "/usr/bin/zsh"  // executable for run_shell; absolute, relative, or PATH lookup
}

lsp

lsp {
    disabled #false
    servers {
        rust {
            command "rust-analyzer" "..."   // language server command
            extensions "rs"                  // file extensions it serves
            no-auto-start #true              // opt-in only
            root-markers "Cargo.toml"        // files marking a project root
        }
    }
}

All fields are optional; the server name is the language it serves. lsp.servers merges key-by-key across config layers.
