Writing an effective prompt for a coding agent
You can write anything to Claude Code — but not everything gets a good fix. "Fix the bug" leaves the agent guessing where, what, and how. An effective prompt for a coding agent names the exact file and function, the observed symptom, and the expected behavior — and asks for one task at a time, not
Asking a coding agent to fix something is like giving a technician an exact address and a description of the fault, instead of just saying "it's broken." The more precise the address, the faster the technician lands on the right spot.
- agent prompting
- A written request to a coding agent that names the exact file and function, an observed symptom, and the expected behavior — so nothing is left to guessing.
- task scoping
- Limiting a request to one focused fix, instead of asking to "fix everything" or "improve other things too" in the same breath.
- expected behavior
- An explicit description of what should happen after the fix, so the agent doesn't have to infer it on its own.
