888-apex

888-apex is an agent for coding agents from ariffazil/AAA. It costs 77 tokens per session (1,417 once invoked), scanned A, original, AGPL-3.0.

A read-only decision gate checks evidence, rules, and authority before an irreversible change or final approval. It also asks structured questions when requirements or boundaries conflict.

In plain words
What is it for?
Use it before irreversible actions, final sealing, or decisions that require checking safety rules and evidence.
Why use it?
It helps prevent unsafe changes or approvals when the available evidence or authority is unclear.

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.

git clone --depth 1 https://github.com/ariffazil/AAA

Or install arifos-federation, the plugin that ships this one along with the rest of its 4 agents.

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

888-apex 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 yesterday.

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.
