Best AI Agent & LLM Ops Skills for Claude Code

prompt engineer

Free

Professional prompt engineering patterns for building robust, secure, and production-ready LLM applications.

Give AI agents the ability to trace decision chains, reconstruct causal sequences, and reason over complex event timelines spanning months or years.

Deploy a hierarchical team of AI agents to perform 15-30 minute deep-dive research with parallel execution.

Turn your AI agent into a senior engineer with strict task classification and verification-driven coding protocols.

ai productivity

Free

High-speed intake for shaping vague prompts, triaging complex tasks, and compressing context for efficient execution.

Builds the organizational memory schema your AI agent needs to answer why — capturing decision provenance, causal chains, and event context that embedding-based retrieval permanently discards.

The "Skill for building Skills": Automate creating, testing, and optimisation of custom workflows.

Architects the right retrieval strategy for every query — teaching your agent when to use RAG, a knowledge graph, or a temporal index instead of defaulting to vector search for everything.

Published AI benchmarks measure brains in jars. They test models in isolation or within a single reference harness — and then attribute all performance to the model. This skill teaches you to decompose agent performance into its two actual components: model capability and harness multiplier. The result is evaluations that predict real-world behavior instead of benchmark theater.

Autonomous research and task loop that builds on previous findings to solve complex objectives while you sleep.

RAG fails quietly. It retrieves documents, returns confident-looking answers, and misses the question entirely — because the question required connecting facts across documents, reasoning about sequence, or tracing causation. This skill gives you a five-question diagnostic checklist that classifies any failing query as either RAG-safe or structurally RAG-incompatible, then maps it to the specific failure pattern and the architectural fix that resolves it.
