ai-agent-evaluation-benchmarking

ai-agent-evaluation-benchmarking is a skill for Claude Code from sickn33/agentic-awesome-skills. It costs 31 tokens per session (1,375 once invoked), scanned A, original, MIT.

A register for measuring how well autonomous AI agents perform tasks. It covers completion rates, planning accuracy, tool-use accuracy, output quality changes, and cost.

In plain words
What is it for?
Use it to define evaluation measures, record benchmark results, and monitor agent capability and cost trends.
Why use it?
It provides a consistent way to compare agent versions and notice when performance or cost changes over time.

About the project

AAS Core is a local control plane for coding agents that lets them search a large catalogue of skills, choose a stack, validate it, and create a reproducible plan. It is used to assemble and review agent workflows through its CLI, local MCP server, catalogue, plugins, and Workbench. The catalogue add-ons provide the skills, plugins, bundles, and workflows that AAS Core helps agents select and validate.

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

ai-agent-evaluation-benchmarking 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 yesterday.

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.

AI Agent Capability Evaluation & Benchmarking

What it is: Standardizes multi-metric capability benchmarking, token cost efficiency, and regression monitoring across autonomous coding agents.

Overview

Provides a standardized, auditable framework and data model for AI Agent Capability Evaluation & Benchmarking operations across distributed engineering and decentralized application systems.

When to Use This Skill

  • When recording agent evaluation runs with a fixed dataset, rubric, runtime/model revision and measured outcomes.
  • When comparing a candidate with a baseline under matched tasks, environment, tool permissions and cost accounting.
  • When generating reproducible CSV, SQL DDL, JSON Schema, and Notion property registers for tracking compliance.

How It Works

  1. Define the parameters, thresholds, and identity bindings required for the target operational register.
  2. Select appropriate boundary enforcement values from validated enum select sets.
  3. Export standardized artifacts (CSV table, SQL DDL, JSON Schema) to integrate into validation CI pipelines.

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.

ai-agent-evaluation-benchmarking is a skill published in the GitHub repository sickn33/agentic-awesome-skills (47,686 stars, last pushed today), licensed MIT. It adds 31 tokens to every session and 1,375 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-10-03.
