Discussion
20 comments analyzed.
Competitors mentioned: Claude Code's deferred tool loading, Headroom (tool call optimization), CodeMode for MCPs
Concerns raised: Using empty-set symbol (∅) as delimiter is poor tokenizer choice, Not returning full tool schema - unclear if compression is just serialization, Confusion between token counts and byte counts in benchmarks, Models trained on JSON templates may struggle with different format, Aggressive compression may be too lossy
Feature requests: Make MCP context cost visible before agent execution, Support for tool search/filtering like other harnesses, Tokenizer-agnostic approach
