cognitive-architecture SKILL.md skillA
cognitive-architecture from jnpiyush/agentx is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add jnpiyush/agentx/cognitive-architecture@v1.0.0Pins v1.0.0 in mdr.lock. Pin the fingerprint instead.

Design and implement the cognitive architecture of AI agents including memory systems, RAG pipelines, and state management. Use when defining agent memory strategy (short/long-term), building RAG pipelines (knowledge retrieval), designing state management systems, or selecting vector databases for semantic search.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Cognitive Architecture > **Purpose**: Patterns for the cognitive components of AI agents: Memory, Knowledge (RAG), and Reasoning. --- ## When to Use This Skill - Designing **Memory Systems** (Conversation history, User profiles, Entity tracking). - Building **RAG Pipelines** (Chunking, Embedding, Retrieval, Reranking). - Managing **Agent State** across sessions. - Selecting **Vector Databases** for knowledge retrieval. ## Decision Tree ``` Designing agent cognition? +-- Need conversation history? -> Short-term memory (context window) +-- Need factual knowledge? -> RAG pipeline (vector store + retrieval) +-- Need user preferences across sessions? -> Long-term memory (database-backed) +-- Need entity tracking? -> Episodic memory (structured state store) +-- Need all of the above? -> Full cognitive architecture (all three layers) +-- Unsure where to start? -> Start with RAG, add memory as needed ``` ## Table of Contents 1. Cognitive Components 2. Reference Patterns 3. Troubleshooting --- ## Cognitive Components A complete agent "brain" consists of three layers: 1. **Context (Short-term Memory)**: The active context window (conversation history). …

How to install
mdr add jnpiyush/agentx/cognitive-architecture@sha256:d93788e194f83370The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
