What is CTF Write-up Generator?
The CTF Write-up Generator is a developer-focused utility designed to streamline the documentation phase of Capture The Flag competitions. By integrating into your agent workflow, it captures critical solve data, metadata, and exploit scripts to produce a professional submission-style document. This specific addition to your library of Openclaw Skills ensures that every solved challenge is backed by a high-quality markdown report that organizers can verify instantly, emphasizing reproducibility and clarity over raw data dumps.
CTF Write-up Generator Use Cases
- Finalizing a challenge solve for competition submission to organizers.
- Documenting exploit scripts for internal team knowledge sharing.
- Creating reproducible solve paths for post-event archival and learning.
- Generating standardized reports for security training and CTF hosting platforms.
How CTF Write-up Generator Works
- The skill scans the current directory for solve scripts, exploit artifacts, and flags using automated bash commands.
- It gathers challenge metadata including title, category, difficulty, and points through user input or file analysis.
- It organizes the solve timeline into concise, 1-3 step logical sections for maximum readability.
- It embeds the final, complete solve script into a standardized markdown template to ensure a single-path solve.
- The final report is validated against a quality checklist and saved as a markdown file ready for immediate handoff.
CTF Write-up Generator Setup
To use this skill, ensure you have a filesystem-based agent such as Claude Code with Python 3 and bash installed. Navigate to your challenge directory and invoke the skill:
