spring-ai-agentcore: Instructions file for Codex

AGENTS.md

spring-ai-agentcore AGENTS.md is an instructions file for Codex, OpenCode from spring-ai-community/spring-ai-agentcore. It costs 1,576 tokens per session, scanned A, original, Apache-2.0.

Project guidance for AI coding assistants working on a Spring Boot starter that connects applications to Amazon AgentCore Runtime, memory, and related tools.

In plain words
What is it for?
Use it to understand the runtime contract, artifact storage, memory integration, browser automation, code interpreter, examples, and helper scripts.
Why use it?
It gives an assistant the project map and explains what the main modules and classes are for, reducing guesswork when changing code.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions AGENTS.md.

This is spring-ai-community/spring-ai-agentcore's own configuration. It tells Codex and OpenCode how to work on spring-ai-agentcore itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything spring-ai-agentcore configures →

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

spring-ai-agentcore AGENTS.md 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 23d 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.

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.
