Tidal_Echo: Instructions file for Codex

AGENTS.md

Tidal_Echo AGENTS.md is an instructions file for Codex, OpenCode from anhe2021212-spec/Tidal_Echo. It costs 3,727 tokens per session, scanned A, original, AGPL-3.0.

A set of deployment instructions for the Tidal_Echo project. It explains what needs to be installed and the order for deploying its backend relay and frontend progressive web app, a website that can be installed and used like an app.

In plain words
What is it for?
Use it when deploying the Tidal_Echo repository. It covers the backend relay first and the frontend progressive web app second.
Why use it?
It reduces deployment mistakes by requiring each part to be verified before moving to the next. The relay must work before the frontend can use it.

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

Tidal_Echo 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 1mo 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

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.
