Struct ContextBudgetInputs 

pub struct ContextBudgetInputs<'a> {
    pub model: &'a str,
    pub provider_window: u64,
    pub system_prompt: Option<&'a str>,
    pub tools_schema: &'a [Value],

}

Everything the budget calculation needs about the NEXT request. Callers pass the segments they will actually send; the engine never guesses.

Fields

model: &'a str

Model the request targets (selects the estimator).

provider_window: u64

Effective provider context window in tokens (override-aware).

system_prompt: Option<&'a str>

The actual effective system prompt, if any.

tools_schema: &'a [Value]

The EXPOSED tool schema set for this request (post-projection).

messages: &'a [SharedMessage]

Conversation history exactly as it will be sent.

skill_contents: &'a [&'a str]

Skill bodies loaded into the request outside system/history.

memory_contents: &'a [&'a str]

Memory bodies loaded into the request outside system/history.

thinking_budget_tokens: u64

Reasoning/thinking reserve in tokens.

next_tool_result_bytes: u64

Byte cap of the next likely tool result (converted to a token reserve at [TOOL_RESULT_BYTES_PER_TOKEN]).

output_reserve_tokens: u64

Requested output reserve (the request’s max_tokens).
