Report #17513
[gotcha] Silent context overflow from massive tool definitions
Implement dynamic tool registration \(progressive disclosure\) where only a subset of relevant tools is exposed per user turn, and aggressively truncate tool descriptions to under 50 tokens each.
Journey Context:
Developers often register all available tools at agent initialization. With 50\+ tools, the JSON schema payload alone can consume 10k\+ tokens. LLMs silently truncate the system prompt or user message to fit the context window, leading to amnesia or ignored instructions. Dynamic loading based on intent prevents this, trading a slight delay for massive context savings and preserving the instruction window.
