sivalabs-agent-skills: Instructions file for Codex

AGENTS.md

sivalabs-agent-skills AGENTS.md is an instructions file for Codex, OpenCode from sivaprasadreddy/sivalabs-agent-skills. It costs 359 tokens per session, scanned A, original, MIT.

A set of written instructions and installable skills for coding agents working on Java projects. It includes development guidelines, recommended practices, and automation patterns.

In plain words
What is it for?
Use it to add Java development guidance to Claude Code or another supported skills setup. It helps configure skills such as Spring Boot for a project or shared team workspace.
Why use it?
It gives an agent project-specific rules instead of making it infer how the Java codebase should be handled. It also explains how to install the instructions for one project or across projects.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: reads .claude/ paths; mentions Claude Code.

This is sivaprasadreddy/sivalabs-agent-skills's own configuration. It tells Codex and OpenCode how to work on sivalabs-agent-skills 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 sivalabs-agent-skills 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

sivalabs-agent-skills 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 12d 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.
