Struct ToolsConfig 

pub struct ToolsConfig {
    pub max_output_tokens: usize,
    pub output_head_tokens: usize,
}

Tool-execution behaviour stored under [tools] in newt.toml (#726).

Tool-output knobs: the token budget that caps every tool’s model-facing output, plus the head/tail split for oversized shell output. This bounds what a single tool result can add to the context window — applied to both read_file (its char backstop) and run_command (its shell envelope) — so a verbose command or a huge file can’t saturate a small local model’s window and abandon the task. Mirrors Codex’s exec_command.max_output_tokens. Distinct from [tui] tool_output_lines, which caps the on-screen DISPLAY by lines.

Fields

max_output_tokens: usize

Maximum tokens of model-facing output any single tool may return before it is truncated (with a marker steering the model to a narrower command / a paginated read). Default: 10000. 0 disables the cap. Tokens are estimated with the shared chars/token heuristic (see crate::tokens).

output_head_tokens: usize

Tokens reserved for the head of an oversized run_command result. The remaining budget is spent on the tail, so failures and summaries at the end survive by default. 0 is pure-tail; values greater than max_output_tokens are clamped to pure-head.
