aj-mcp: Skill for Codex

.agents/skills/aj-mcp-java8/SKILL.md

aj-mcp-java8 is a skill for Codex from lightweight-component/aj-mcp. It costs 95 tokens per session (1,313 once invoked), scanned A, original, GPL-3.0.

Repository-specific guidance for the AJ-MCP Java 8 SDK, a software library for building MCP clients and servers with Java 8. It covers development, review, testing, debugging, and documentation.

In plain words
What is it for?
Use it when working on the SDK’s shared, client, or server modules; protocol messages; version negotiation; transport methods; annotations; or lifecycle behavior.
Why use it?
It helps an agent make changes that fit this older Java SDK and its communication protocol.

Skill for Codex

Written for Codex: agents/openai.yaml present. Also seen: installed under .agents/ (shared by several agents).

This is lightweight-component/aj-mcp's own configuration. It tells Codex how to work on aj-mcp 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 aj-mcp 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

aj-mcp-java8 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 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.

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.
