TaskSlices: why AI agents receive small tasks
Small TaskSlices bound the context and simplify review. Learn which tasks can be separated and why integration tests and dependency planning still matter.
What is a TaskSlice?
A TaskSlice is a bounded implementation step within a larger task. Anvil Coder plans these steps with dependencies. The aim is a manageable working context: the specific change, relevant interfaces and applicable project rules.
Small does not automatically mean independent or correct. One step may need another step’s output. Bounding the context helps execution but does not replace verification.
How can you split a task meaningfully?
A simplified email-validation example could be:
- Define the expected behavior and error message.
- Add server-side validation.
- Display the error in the interface.
- Check the interaction with a regression test.
This is a planning example, not a measured run. The interface depends on the API’s error format. Those dependencies need to be visible in the plan before parallel work starts.
When is a task too small?
If multiple steps repeatedly edit the same file or can only be understood together, splitting them may create more coordination than benefit. Additional steps also consume model calls and review time. Do not separate tightly connected changes simply to increase the slice count.
A useful step has a named purpose, clear inputs and a testable result. Its appropriate size depends on the repository and available context, not a fixed line count.
What needs checking after individual steps?
Inspect the integrated revision for interface failures and regressions. A successful isolated test does not cover every interaction. Commit history records changes; run reports and executed tests provide additional evidence.
See the Anvil Coder workflow for how requirements, planning and execution fit together.
