Included Skills4

cortex-orientationskills/cortex-orientation/SKILL.md

Default operating mode for cortex-equipped sessions. Auto-injected at session start by the cortex-session-start hook (no Skill-tool invocation required). Invoke explicitly when the user says "orient me", "cortex orientation", "load cortex defaults", "what's the cortex protocol", "remind me of the operating mode", or after a long compaction. Establishes orchestrator identity, situation modeling, listening protocol, producer/verifier separation, substrate inviolability, pattern-vs-state filter, and handoff usage.

handoff-managementskills/handoff-management/SKILL.md

Save and load work-in-progress state for session continuity. Distinct from learnings (permanent knowledge); handoffs are ephemeral session state. Triggers on "save progress", "create handoff", "show handoff", "what was I working on", "handoff", "session handoff", "resume work", "where did we leave off", "pick up where I left off".

learning-captureskills/learning-capture/SKILL.md

Capture insights to the cortex ledger via the tag_learning MCP tool. Use for discoveries, decisions, errors, and patterns worth remembering for the next session. Triggers on "tag this", "remember this", "save learning", "capture this", "worth remembering", "store this insight", "log this discovery", "note this for next time", "add to ledger", "persist this".

ledger-knowledgeskills/ledger-knowledge/SKILL.md

Query the cortex knowledge ledger for prior learnings, patterns, and decisions. Use the MCP tools first; CLI is a fallback. Triggers on "list learnings", "show learning", "check the ledger", "what do we know about", "search learnings", "find in ledger", "search for pattern", "what's stored", "lookup", "fetch from ledger", "ledger stats", "how many learnings".
