Stop Fighting the Context Limit - Scope Each Agent to One Small Task
Stop Fighting the Context Limit
Everyone complains about LLM context limits. "If only I had 500K tokens, my agent could understand the whole codebase." But the developers getting the most out of AI agents are not fighting the context limit. They are working with it.
The trick is simple: scope each agent to one small task.
One Job, One Agent
Instead of asking an agent to "refactor the authentication system," break it down:
- Agent 1: Fix the crash in the login flow when the token expires
- Agent 2: Add the "Remember me" checkbox to the login form
- Agent 3: Update the auth tests to cover the new edge case
Each of these tasks fits comfortably in a small context window. The agent does not need to understand your entire codebase. It needs to understand the three files relevant to its specific task.
Why Small Scope Wins
Small-scoped agents produce better results for several reasons:
- Less noise - the agent is not distracted by irrelevant code
- Faster execution - fewer tokens to process means faster responses
- Easier review - a small, focused diff is easy to verify
- Lower cost - fewer input tokens means lower API costs
- Better accuracy - the agent can focus deeply on one problem
The Scoping Workflow
Before launching an agent, spend 60 seconds writing a clear scope:
- What exactly should change?
- Which files are involved?
- What does "done" look like?
If you cannot describe the task in 2-3 sentences, it is too big. Break it down further.
Composing Small Tasks into Big Results
The power comes from composition. Ten small agents, each completing a focused task, can collectively accomplish a major feature. You are the orchestrator - deciding what needs to happen, in what order, and with what constraints.
This is closer to how a senior engineer manages a team than how a developer writes code. You are not fighting the context limit anymore. You are designing around it - and getting better results in the process.
