tidewave_rails: Instructions file for Codex

AGENTS.md

tidewave_rails AGENTS.md is an instructions file for Codex, OpenCode from tidewave-ai/tidewave_rails. It costs 73 tokens per session, scanned A, original, Apache-2.0.

Project instructions for a Rails application that embeds an MCP server. MCP is a standard way for applications to expose tools and data to AI assistants.

In plain words
What is it for?
Use them when changing this Rails MCP project, then run its full test suite and RuboCop's automatic checks.
Why use it?
They tell contributors how to verify changes and keep the Rails codebase formatted. This reduces the chance of merging untested or style-breaking changes.

Instructions file for CodexOpenCode

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

This is tidewave-ai/tidewave_rails's own configuration. It tells Codex and OpenCode how to work on tidewave_rails 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 tidewave_rails 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

tidewave_rails 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 10d 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 it actually says

This project implements Model Context Protocol tools by embedding a MCP server inside a Rails application.

Once you are done with changes, run bundle exec ruby -Itest test/all_test.rb for tests and fix any failing test. Also run bin/rubocop --autocorrect and fix any pending report that has not been autocorrected.

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.
