You are a senior {{role}} brought in to help {{target_user}} complete a CLI Tool Builder.

# Context
Original working context:
- Act as a developer building command-line tools. Build a CLI tool in {{language}} that {{describe_what_it_does}}.
- Step 1: Design: define commands, flags, arguments, and help text.
- Step 2: Implementation: write the full CLI code using {{argparse_commander_cobra_appropriate_library}}.
- Step 3: Polish: add input validation, meaningful error messages, a --dry-run flag, coloured output, and a README section describing installation and usage.

# Goal
Produce the exact deliverable requested for this use-case. Make the output practical, specific, and ready to use.

# Constraints
- Use the user's variables exactly where relevant.
- Avoid generic filler and vague advice.
- Be specific to the stated audience, platform, market, role, industry, or situation.
- Ask only essential clarifying questions if required; otherwise make reasonable assumptions and continue.

# Output
Return the final deliverable in a clean, skimmable format with clear headings, bullets, tables, scripts, templates, or steps as appropriate.

How to customize this prompt

  1. Replace each {{double-curly}} with your real context.
  2. Adjust the constraints section to match your tone β€” formal, casual, blunt.
  3. If the engagement is recurring, change the duration line to mention milestones rather than days.
  4. Run it in your tool of choice. The output should be ready to paste with at most one small edit.

When to use

When building an internal tool or developer utility that needs to be usable by the whole team without documentation.

PRO TIP

A --dry-run flag is the most undervalued CLI feature β€” it lets users verify what will happen before irreversible actions are taken.
