ai-context-engineering-for-qa AGENTS.md is an instructions file for Codex, OpenCode from vlad-ryzhkov/ai-context-engineering-for-qa. It costs 613 tokens per session, scanned A, original, Unlicense.

A project-context file for a quality-assurance codebase that tells agents which core instructions, technology rules, safety practices, and testing skills to follow.

In plain words
What is it for?
It guides QA work, repository skills, coding constraints, dependency choices, safety checks, and documentation language.
Why use it?
It gives agents a consistent starting point and makes clear which instructions take priority.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions CLAUDE.md; mentions AGENTS.md; $skill-name invocation.

This is vlad-ryzhkov/ai-context-engineering-for-qa's own configuration. It tells Codex and OpenCode how to work on ai-context-engineering-for-qa itself, so it is not a mod to install elsewhere.

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

ai-context-engineering-for-qa 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 4d 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.

How it starts

The opening of the file, as written. The whole thing — 60 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md — Project Context Bridge

CORE INSTRUCTION

YOU MUST READ AND FOLLOW CLAUDE.md AT THE ROOT OF THIS PROJECT.

CLAUDE.md is the Single Source of Truth for:

  1. Tech Stack: Kotlin, JUnit 5, Allure, ktlint — LOCKED.
  2. Safety Protocols: No destructive commands, no .env leaks.
  3. Code Style: Formatting, naming conventions, assertion rules.
  4. Communication Protocol: CLI-mode, no preambles, tool-first.

QA AGENT PERSONA

YOU MUST ALSO READ: .claude/qa_agent.md

qa_agent.md defines:

  • QA Lead philosophy and mindset
  • Anti-patterns to avoid
  • Workflow protocols (Fail Fast, Compilation Gate)

CRITICAL BEHAVIOR

  • If CLAUDE.md conflicts with any other instruction, CLAUDE.md WINS.
  • Do NOT generate code that violates the strict dependencies listed in CLAUDE.md.
  • All documentation and skill content must be written in English, unless explicitly stated otherwise.

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.
