Memory, Media and Tools in Context Engineering

Lessons in this section

1. Memory Management

   How an app manages memory over time: short-term, long-term and state, extracting decisions and open tasks, compacting at the right time, and the lifecycle and privacy rules for stored memory.

2. Document and Media Context

   How PDFs, Word files, spreadsheets, slides, images, audio and video become labelled text a model can use, how to keep unclear parts marked as unclear, and a four-step framework for any file.

3. Tool and Connector Context

   How tool calls work, why tool definitions and results are context, how to check arguments and shape results with status, source and time, and how tools, APIs and connectors differ.
