Prompt template

Copy this structure for claude code prompts for writing regex patterns, then fill in context from your real codebase. Vague one-liners produce vague diffs.

You are an expert reviewer helping with writing regex patterns.

Context: [paste the relevant code, error, or requirements here]

Task: [state exactly what you want — e.g. "review for correctness and edge cases", "generate tests covering X", "explain why this fails"]

Constraints:
- Keep changes minimal and match the existing code style
- Call out any assumptions you're making
- If something is ambiguous, ask instead of guessing

Output format: [e.g. a diff, a bullet list, a single function]

Why this structure works

Separating context, task, constraints, and output format gets more consistent results than a single free-form sentence — the model doesn't have to guess scope or format when you ask about claude code prompts for writing regex patterns.

Before you paste the result

Run the code or apply the change in a branch — never merge blind
Ask for a second pass focused on edge cases and security
Strip secrets from any context you paste into a third-party model

Practical steps

1
Paste context
Give the model the smallest relevant snippet for claude code prompts for writing regex patterns, not the whole repo.
2
State the task
Be explicit about output format and constraints for Claude Code Prompts for Writing regex patterns.
3
Iterate once
Ask for a critique pass focused on correctness for claude code prompts for writing regex patterns.
4
Verify locally
Never merge AI output for claude code prompts for writing regex patterns without running it yourself.

Tips that save time

Write down success criteria for claude code prompts for writing regex patterns before you open docs or AI chat.
Keep a failing test or sample input next to any change involving claude code prompts for writing regex patterns.
