ctf-writeup

Generates a single standardized submission-style CTF writeup for competition handoff and organizer review. Use after solving a CTF challenge to document the solution steps, tools used, and lessons learned in a structured format.

Quality

Content

70%Weight 40%Scale 1-3

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The body is well-structured and actionable for a generator skill, with clear workflow and verification checklist. The main weakness is redundancy across the Guidance, Checklist, and DO/DON'T sections, and a placeholder rather than executable solve-script in the template.

Suggestions

Consolidate the Guidance, Best Practices Checklist, and Quality Guidelines DO/DON'T sections — several rules ('one complete solving path', 'tag code blocks with language') appear in two or all three; merge into one checklist to cut redundancy.

Make the submission template's solve-script block more concrete by showing the expected structure (imports, challenge-data input, flag output) as a fillable runnable skeleton rather than a one-line placeholder.

Add an explicit validate→fix→retry note for the final writeup (e.g., 'run the script end-to-end and confirm it prints the flag before finalizing') to strengthen the existing checklist into a feedback loop.

Dimension	Reasoning	Score
Conciseness	Largely lean with no concept-explanation padding, but the Guidance, Best Practices Checklist, and Quality Guidelines DO/DON'T sections restate the same points (one complete path, tag code blocks), so it could be tightened.	2 / 3
Actionability	Provides executable discovery commands and a complete submission template, but the core solving script is a templated placeholder description rather than copy-paste-ready executable code.	2 / 3
Workflow Clarity	Clear two-step sequence (Gather Information then Generate Write-up) capped by an explicit Best Practices Checklist that acts as a verification checkpoint before finalizing.	3 / 3
Progressive Disclosure	Single self-contained, well-organized file with clear sections and no nested or missing references; appropriate for the skill's scope with no content needing to be split out.	3 / 3

Description

100%Weight 40%Scale 1-3

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description is strong: concrete, with natural trigger terms, an explicit 'Use after...' clause covering both what and when, and a distinct competition-writeup niche. No changes needed.

Dimension	Reasoning	Score
Specificity	Names several concrete actions — generating a standardized writeup and documenting solution steps, tools used, and lessons learned — matching the multiple-concrete-actions anchor.	3 / 3
Completeness	Explicitly answers both what (generates a submission-style writeup for handoff/review) and when ('Use after solving a CTF challenge to document...'), with an explicit trigger clause.	3 / 3
Trigger Term Quality	Uses natural terms a user would say ('CTF writeup', 'solving a CTF challenge', 'competition', 'organizer review', 'tools used', 'lessons learned') with good coverage.	3 / 3
Distinctiveness Conflict Risk	Has a clear niche (competition writeup generation for organizer review) with distinct triggers, unlikely to conflict with unrelated skills.	3 / 3
	Total	12 / 12 Passed
