Analyzing Sessions

Category: Dev Tools  ·  Sub-category: tools-misc  ·  Last updated:
Analyzes Claude Code sessions from a user-defined start date through today. Executes SWOT analyses, self-critiques, and self-reflections for each skill, sub-agent, command, workflow-skill, and rule active in the session range, reading generated output artifacts (concept cards, plans, handoff reports) in scope and re-verifying their stated open items against current repo state rather than trusting them at face value. Generates classified improvement suggestions grouped by component and priority, persisted to .claude/output/analyzing-sessions/. With explicit user approval, may also correct a stale commit-SHA reference directly in a source artifact it reads. Use when running a post-session retrospective, auditing skill or agent performance, building an improvement backlog, or identifying systemic issues across skills, agents, and rules from a session or date range.
