Report #103851

[agent\_craft] Does a detailed persona improve coding agent output?

Use a minimal role frame \('expert software engineer'\) plus concrete constraints, output format, and verification standard. Skip backstory, tone adjectives, and fictional expertise. Constraints beat character for coding agents.

Journey Context:
Prompt engineering folklore recommends elaborate personas \('You are a 10x Staff Engineer at a FAANG...'\), but excessive persona detail competes with task instructions and can encourage verbose explanation instead of tool use. Research-backed prompting favors clear task definitions, explicit output formats, and verifiable constraints over character acting. A strong pattern is: 'You are a careful software engineer. Read the file before editing. Verify with tests. Return only the diff.' That gives identity without noise. The audience is code, not a human reader, so flattery is wasted tokens.
