Report #42388

[agent\_craft] Agent summarizes previous context to save tokens but loses exact variable names, file paths, or API endpoints needed for subsequent tool calls

When compacting context, enforce a 'literal preservation' rule for identifiers. Summarize the narrative and logic, but output a dedicated 'Key Identifiers' section that lists exact file paths, variable names, and URLs verbatim.

Journey Context:
LLMs naturally summarize by abstracting details \(e.g., 'processed the user data file' instead of 'read /tmp/user\_data\_829.csv'\). This saves tokens but breaks downstream tool calls that require the exact path. The tradeoff is slightly longer summaries vs. execution failure. Keeping a structured dictionary of literals within the summary ensures the agent retains the exact pointers needed for tool execution.
