[synthesis] Agent reasoning degrades due to context pollution from progressively bloated tool call arguments

Monitor the token size of tool call payloads per session; if payload size trends upward while task completion stalls, inject a context compression step or halt the agent to prevent hallucination.

Journey Context:
Agents often pass entire file contents or massive JSON objects into tool calls just in case. This works initially but bloats the context window in subsequent steps. The agent does not error out; it just starts ignoring parts of the bloated payload or hallucinating based on the noise. The synthesis is recognizing that tool payload size is a leading indicator of context pollution, distinct from total prompt size, because it represents the agent's inability to filter relevant information.
