The Token Compression Illusion: Why I'm Skeptical of RTK

- RTK's claimed 60-90% savings are misleading as they refer only to reduced terminal output, not overall API costs, ignoring major cost drivers like file reads and system prompts.
- RTK poses a 'silent failure' risk where critical terminal output can be mangled or dropped without the AI agent's knowledge, leading to errors and lost context.
- The tool lacks accuracy benchmarks, such as task success rate, making it hard to evaluate its real-world effectiveness beyond token reduction claims.
- RTK is better suited as a feature integrated into developer tools, not as a standalone product, making it vulnerable to obsolescence as mainstream CLIs adopt similar native optimizations.
- It relies on brittle parsing of terminal output formats, which can break with updates to common tools like git or npm, risking silent corruption of data fed to AI agents.
