Editing as Language: Teaching LLM Agents a Grammar for Native Context Editing

In this paper, we propose the Native Context Editing (NCE) framework, which gives language model agents a grammar for natively editing their own context.

Key points

  • A synopsis in novels folds a story into a few lines; a function in code gathers many steps with a single execution.
  • Context editing is native to language itself.
  • By encoding context-editing operations in a grammar of dedicated special tokens, we teach the agents to invoke edits through the language itself.
  • Compared with context-editing methods that learn to generate tool-use code within specific external harness environments, our approach integrates context editing as an internal mechanism of the model's native generation process, enabling better generalization across diverse real-world workflows.
