rag-learning-academy: Skill for Claude Code

.claude/skills/benchmark/SKILL.md

benchmark is a skill for Claude Code from TakaGoto/rag-learning-academy. It costs 9 tokens per session (1,118 once invoked), scanned A, original, MIT.

A skill for measuring the operational performance of a RAG pipeline—the code that searches documents and generates answers. It focuses on speed, capacity, token use, and memory rather than answer quality.

In plain words
What is it for?
Benchmarking an existing RAG project, finding performance bottlenecks, and measuring latency, throughput, token costs, and memory use.
Why use it?
It shows where a working pipeline is slow, expensive, or using too many resources, and establishes performance baselines for comparison.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

benchmark scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Benchmark: Measure Your RAG Pipeline's Performance

Scope: This skill focuses on operational performance (latency, throughput, token costs, memory). For answer quality metrics (faithfulness, relevancy, correctness), use /evaluate.

Set up and run comprehensive benchmarks on the learner's RAG pipeline to identify bottlenecks and establish performance baselines.

Step 1: Identify the Pipeline

Welcome! Let's measure how your RAG pipeline performs under the hood.

First, check whether the learner has existing work to benchmark:

  • Look for a learner profile at progress/learner-profile.md and for code in src/ and projects/.

  • If pipeline code exists in projects/, great — proceed. If multiple pipelines exist, ask which to benchmark.

  • If no pipeline or RAG code exists anywhere in projects/ or src/, guide them warmly:

    "Looks like you don't have a pipeline to benchmark yet — no worries! Let's get you set up first. Run /build to create your first RAG pipeline, and once it's running you can come back here to see exactly where the time and tokens go. It won't take long!"

    Stop here — do not continue to Step 2.

  • If a pipeline is found, catalog the pipeline components: loader, chunker, embedder, vector store, retriever, generator.

Step 2: Define Benchmark Scope

Ask the learner what they want to measure, or suggest a comprehensive benchmark covering:

Latency Metrics

  • End-to-end latency: Total time from query to answer
  • Retrieval latency: Time to embed the query and fetch results from the vector store
  • Generation latency: Time for the LLM to produce the answer
  • Embedding latency: Time to embed a single query or a batch of documents

Throughput Metrics

  • Queries per second: How many queries can the pipeline handle?
  • Indexing throughput: How fast can documents be chunked, embedded, and stored?

Quality Metrics

  • Retrieval accuracy: Precision@k, Recall@k, MRR (Mean Reciprocal Rank)
  • Answer quality: Faithfulness, relevancy (via RAGAS or custom evaluators)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

benchmark is a skill published in the GitHub repository TakaGoto/rag-learning-academy (18 stars, last pushed 5mo ago), licensed MIT. It adds 9 tokens to every session and 1,118 once invoked, about $0.0000 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
