llm-evals

llm-evals is a skill for Claude Code, Codex from VoDaiLocz/kilo-kit-mcp. It costs 45 tokens per session (904 once invoked), scanned A, original, Apache-2.0.

A framework for testing and monitoring applications that use large language models, including chatbots, retrieval systems, and multi-step agents. It measures outputs, tool choices, and reasoning steps against defined tests or scoring rules.

In plain words
What is it for?
Use it to evaluate RAG systems, build test suites, score agent trajectories, run model-based judging, and add quality checks to CI/CD.
Why use it?
It replaces informal checking with repeatable evaluations that can reveal regressions and block unreliable changes.

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

llm-evals 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 11d 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.

LLM Evaluation & Validation Framework

Overview

The llm-evals skill provides a systematic framework for evaluating and monitoring Large Language Model (LLM) applications throughout the development lifecycle. It bridges the gap between ad-hoc testing and production-grade reliability by implementing rigorous evaluation pipelines, metric-driven gating, and dataset versioning.

When To Use

  • Setting up automated evaluation pipelines for LLM chains.
  • Developing or refining RAG (Retrieval-Augmented Generation) systems.
  • Preparing LLM applications for production deployment.
  • Investigating performance regressions in complex, multi-step agent trajectories.
  • Defining custom rubrics for LLM-as-a-Judge scenarios.

Core Concepts

  • Trajectory-Level Evaluation: Scoring intermediate reasoning steps, tool choices, and argument precision, moving beyond just final output metrics.
  • LLM-as-a-Judge: Using capable models (e.g., GPT-4o, Claude 3.5 Sonnet) as automated judges to score outputs based on user-defined rubrics.
  • Metric Tiers:
    • Unit: Single prompt/completion pairs.
    • Integration: Individual chains or multi-step logic.
    • System: End-to-end user intent fulfillment evaluation.
  • Golden Datasets: Version-controlled suites containing ground-truth, negative test cases, and edge cases to ensure consistent benchmarks.
  • Calibration: Ensuring LLM judges align with human grading, including inter-rater reliability checks.

Workflow

  1. Dataset Curation: Create and version control evaluation suites using JSON/YAML formats, incorporating synthetic failure injections.
  2. Metric Definition: Define evaluation criteria (e.g., faithfulness, relevancy, G-Eval) using established frameworks.
  3. Execution: Run evaluations locally or in CI environments using tools like promptfoo or deepeval.
  4. Analysis: Review evaluation reports to identify bottlenecks or high-error clusters.
  5. CI/CD Integration: Incorporate gating steps in deployment pipelines to automatically block commits failing established regression thresholds.
  6. Continuous Monitoring: Shift evaluation metrics into production monitoring (e.g., Langfuse) to track drift.

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.
