What it does

AWS Harness is an agent skill from hoodini/ai-agents-skills. Build a new AI agent on AWS and deploy it easily, OR wrap and deploy an agent you already have, using the Amazon Bedrock AgentCore harness. Explains what an "agent harness" is (the runtime scaffolding around a model - agent loop, tool execution, memory, identity, observability), then gives two fully-working, verified paths - (A) scaffold + ship a new agent with the AgentCore CLI (create/dev/deploy/invoke), and (B) deploy a prepared agent (Strands, LangGraph, or custom) via the SDK wrapper or a FastAPI + Docker +…

Its SKILL.md is about 4.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Backend & APIs, covering Project scaffolding, Serverless and Building AI agents. It works with Amazon Web Services, Amazon Bedrock, LangGraph and Docker. The repository describes itself as: 🧠 AI Agent Skills Repository - A curated collection of specialized skills for AI coding agents (Claude Code, GitHub Copilot, Cursor, Windsurf). Created by Yuval Avidani using…

When your agent uses it

  • The goal is to create
  • Deploy an agent on AWS AgentCore
  • Agentcore create
  • Agentcore deploy

Example prompts

  • “agent harness”
  • “/aws-harness”

Requirements

  • Python 3
  • Node.js
  • Docker

Workflow steps

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

  1. Install
  2. Create the project
  3. The agent code (this is all an AgentCore agent is)
  4. Test locally (free) before deploying
  5. Deploy to AWS
  6. Invoke
  7. Add production harness components
  8. Clean up (do NOT skip - this costs money)

What it can do on your machine

Read from SKILL.md and the folder at commit f7a43d8. 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

    Shell commands in SKILL.md call:

    • pip
    • docker
    • aws
    • npm
    • uv

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

  • Network

    Links to these hosts (documentation or services it may open):

    • github.com
    • docs.aws.amazon.com
    • strandsagents.com

    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

AWS Harness loads about 4.2k tokens when it runs. Until then it costs about 220 tokens; SKILL.md has 1,157 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~220
When it runs · the whole SKILL.md, loaded when a task matches
~4.2k

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: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NoteMentions a .env fileSKILL.md:99
    .env.local          # local secrets (gitignored)

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); files beside SKILL.md are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 1,157 words (~4,207 tokens).

“Take an AI agent from an empty folder - or from code you already have - to a live, serverless endpoint on AWS. Every command and import below is verified against official docs (sources at the bottom).”
