At a glance

Provides reference guides and Python scripts for prompt optimization, RAG evaluation, and agent orchestration when building or tuning LLM systems.

  • Works in 3 steps: Prompt Engineering Patterns → Llm Evaluation Frameworks → Agentic System Design
  • Optimizing a prompt for a production LLM feature
  • SKILL.md covers Quick Start, Core Expertise, Tech Stack and Reference Documentation, plus 7 more sections
  • Runs Python scripts from its folder; calls python, kubectl and docker

What it does

This skill packages three Python scripts - a prompt optimizer, a RAG evaluator, and an agent orchestrator - alongside three reference documents on prompt engineering patterns, LLM evaluation frameworks, and agentic system design. It frames its scope broadly across production AI and data systems, from prompt design through deployment and monitoring.

Each reference file is pointed to as the detailed guide for its topic: a prompt-engineering-patterns file for pattern selection, an llm-evaluation-frameworks file for step-by-step evaluation processes, and an agentic-system-design file for system design and deployment guidance. It also names three production patterns - scalable data processing, ML model deployment, and real-time inference - as areas it covers.

The scripts are invoked from the command line with input and output directory flags, for example running the prompt optimizer over a folder of inputs and writing results to an output folder.

When your agent uses it

  • Optimizing a prompt for a production LLM feature
  • Evaluating a RAG pipeline's retrieval and answer quality
  • Designing the architecture for a multi-agent system

Example prompts

  • “Run the prompt optimizer over my prompts in data/ and show the results.”
  • “Evaluate this RAG pipeline's outputs with the bundled evaluator.”
  • “Help me design the architecture for an agentic support system.”

Requirements

  • Python

Workflow steps

3 steps, taken from the step headings in SKILL.md.

  1. Prompt Engineering Patterns
  2. Llm Evaluation Frameworks
  3. Agentic System Design

What it can do on your machine

Read from SKILL.md and the folder at commit 8c3b576. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 3 files in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • python
    • kubectl
    • docker
    • helm

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use kubectl, docker and helm, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Senior Prompt Engineer loads about 1.4k tokens when it runs, and up to ~2.5k if it reads all its reference files. Until then it costs about 114 tokens; SKILL.md has 438 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~114
When it runs · the whole SKILL.md, loaded when a task matches
~1.4k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 438 words (~1,386 tokens).

“World-class senior prompt engineer skill for production-grade AI/ML/Data systems.”
