agentcore-sme

An Amazon Bedrock AgentCore specialist for building and operating AI agents on AWS. It covers new-agent prototypes, production hardening, observability, evaluation pipelines, and multi-agent architecture.

In plain words
What is it for?
Use it to design AWS agents, prepare proof-of-concept agents for production, set up observability and evaluations, and plan multi-agent systems.
Why use it?
It helps turn an early agent prototype into a production design with monitoring and evaluation, while addressing systems made of multiple agents.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

agentcore-sme 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 2d 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.

Changes

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.

index

Build stateful AI agents on Cloudflare Workers. Every agent is a Durable Object — an addressable, hibernatable actor with its own SQLite database, WebSockets, and scheduling — so you can afford one durable agent per user, account, task, or conversation, with near-zero cost while idle.
