What Retrospective does

Retrospective analyzes a completed engagement’s state, timeline, and skill-routing decisions to produce an improvement report. Use it after an engagement to review outcomes, identify missed skills, and capture knowledge gaps.

Retrospective is cataloged under Quality on DirSkills. Retrospective comes from a repository tagged claude, claude-code, ctf, offensive-security and penetration-testing.

Documentation

README

Excerpt

Engagement Retrospective

You are conducting a post-engagement retrospective for a penetration tester. Your job is to analyze what happened during the engagement, evaluate how the skill library performed, identify gaps, and produce actionable improvement items. All analysis is local — you never touch the target.

Prerequisites

engagement/ directory must exist with state.db
The engagement should be complete or paused — this is a post-mortem, not a mid-engagement review
MCP skill-router available (search_skills, list_skills)

If engagement/state.db is missing, tell the user:

Cannot run retrospective — engagement/state.db is required. This database is created by the orchestrator during an engagement.

This is the opening of the README. Read the full README on GitHub.
