Migrated from skills/omniroute compression/SKILL.md (preserved curated content) OmniRoute — Compression Requires OMNIROUTE URL and OMNIROUTE KEY . See [entry point SKILL](https://raw.githubusercontent.com/diegosouzapw/OmniRoute/main/skills/omniroute/SKILL.md) for setup. Overview OmniRoute compresses token payloads before forwarding to providers. No code changes required — set it once, it applies to all requests transparently. Engine Best for Typical savings RTK Terminal / build / test / git output 60–90% Caveman Human prose, chat history 46% input Stacked ( rtk → caveman ) Mixed coding sessions 78–95% MCP accessibility filter Browser/accessibility tool results 60–80% Get current settings Enable RTK (best for coding agents) Enable stacked mode (maximum savings) Enable Caveman (prose / chat) Caveman intensities: lite (safe), standard (balanced), aggressive (long sessions), ultra (context recovery). Preview compression before enabling Response includes compressed , original length , compressed length , savings pct . MCP accessibility tree filter (browser agent use) When OmniRoute is used with browser/Playwright MCP tools, it automatically compresses verbose accessibility tree tool results. Enabled by default; configure thresholds: collapseThreshold : collapse sibling lines when ≥ N repeats (default 30). maxTextChars : hard truncate after N chars with navigation hint (default 50000).
