About the project

Agentic Platform is an AWS reference architecture for running AI-agent workflows with compute options such as Amazon EKS or Bedrock AgentCore and frameworks including LangChain, LangGraph, and Strands. It is for developers exploring a multi-layer platform with shared libraries, gateway services, infrastructure stacks, and agents implemented with different frameworks. The catalogue add-ons help coding agents navigate and work with the platform's monorepo.

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

sample-agentic-platform AGENTS.md scanned grade A with 1 finding 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 2mo 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.

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.
