Your AI coding agent isn’t stupid

After using Cursor and Claude Code daily, I’ve noticed that when an AI coding agent drifts or forgets constraints, we assume it’s a model limitation.

In many cases, it’s context management.

A few observations:

  • Tokens are not just limits. They’re attention competition.
  • Even before hitting the hard window limit, attention dilution happens.
  • Coding tasks degrade faster than chat because of dependency density and multi-representation juggling (diffs, logs, tests).

I started managing context deliberately:

  • Always write a contract
  • Chunk sessions by intent
  • Snapshot state and restart
  • Prefer on-demand CLI instead of preloading large MCP responses

It dramatically improved the stability of the agent.

Curious how others are handling context optimization.

I also wrote a detailed breakdown of:

  • How tokens and context windows actually affect stability
  • Why coding degrades faster
  • A practical context stack model
  • Why on-demand CLI retrieval is often more context-efficient
