Module: RubynCode::Context::MicroCompact

Defined in:
lib/rubyn_code/context/micro_compact.rb

Overview

Zero-cost compression that runs every turn. Replaces old tool results (except the most recent N) with short placeholders to reduce token count without losing conversational continuity.

Constant Summary collapse

PLACEHOLDER_TEMPLATE = 
'[Previous: used %<tool_name>s]'
MIN_CONTENT_LENGTH = 
100
