Detailed Description

Implementation of the tool-result content classifiers (#44).

Function Documentation

is_effectively_empty()

bool entropic::mcp::is_effectively_empty

(

std::string_view

s

)

True if s is empty or contains only ASCII whitespace.

True if input is empty or contains only ASCII whitespace.

looks_like_tool_error()

bool entropic::mcp::looks_like_tool_error

(

std::string_view

content

)

Heuristic: the rendered tool-result text reads as an error.

Heuristic match for an error-shaped tool result string.

Recognises (case-insensitively, after stripping leading whitespace):

• Error: … / ERROR …
• [error] …
• top-level { "error": … }

Negative case: "… error somewhere in the middle" is NOT classified as error — only leading-token shapes count.

bool entropic::mcp::starts_with_json_error ( std::string_view  trimmed )

truncate_to_cap()

void entropic::mcp::truncate_to_cap	(	std::string &	content,
		int	cap
	)

Truncate tool-result content in place when it exceeds cap.

Truncate content in place when it exceeds the byte cap.

Demo ask #6 (v2.1.0). When cap is 0, no-op. When content size exceeds cap, the content is shrunk to cap - tail.size() bytes followed by a trailing \\n[... truncated, N more bytes] marker so downstream consumers (the model, classification, the duplicate cache) see the bounded form with a clear signal that bytes were lost. Final size is ≤ cap.

Parameters

content	Mutable string; truncated in place when exceeded.
cap	Maximum byte length. 0 disables. @utility
