session-learner
Extract and persist learnings from the current session. This skill should be used when the user wants Claude to analyze the conversation and capture insights, patterns, preferences, or knowledge discovered during work. Triggers on requests like "learn from this session", "what did we learn", or "capture insights".
systematic-debugging
Structured debugging methodology for investigating and resolving technical issues. Use this skill when debugging any technical problem, investigating errors, or troubleshooting unexpected behavior to ensure root cause analysis rather than symptom treatment.
nb-notes
Manage persistent notes and todos using the nb note-taking system. This skill should be used when capturing cross-session learnings, technical decisions, deferred tasks, or codebase patterns that should persist beyond the current conversation. Use proactively after solving bugs, making architectural decisions, or discovering important patterns. Triggers on requests like "what did I learn yesterday", "check my notes", "what learnings do I have about X", or "capture insights". Do NOT use for tracking current work-in-progress (use TodoWrite for that).

optimizing-agent-context
Optimizes what a project loads into every coding-agent session. Counts which skills, plugins, slash commands, and subagents past sessions actually invoked, prunes the rest from the load set, then tightens CLAUDE.md against the same data by deleting dead references, replacing ignored always-do rules with hooks, and pinning the skills that carry the dev cycle in a short table. Use when the user asks to optimize their agent setup or project context, prune unused skills or plugins, audit skill usage, or slim down CLAUDE.md.
