ovo AGENTS.md

ovo AGENTS.md is an instructions file for Codex, OpenCode from qntx/ovo. It costs 189 tokens per session, scanned A, original, Apache-2.0.

A set of instructions for how an agent should behave while building software. It covers simplicity, modular design, dependencies, and long-term technical decisions.

In plain words
What is it for?
It is for guiding software implementation choices, such as keeping components separate, reusing existing libraries, and growing the system in working stages.
Why use it?
It gives the agent clear priorities when requirements change, including removing obsolete code and avoiding unnecessary compatibility layers or speculative complexity.

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

ovo 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.

What it actually says

AGENTS.md

  • Do not preserve backward compatibility. Remove obsolete paths instead of adding compatibility layers, fallbacks, or migrations.
  • Choose the simplest implementation that fully meets the current requirements. Avoid speculative abstractions, configuration, and indirection.
  • Grow the system in layers. Start from the smallest version that works end to end, and add each new capability on top of a product that already works. Never trade a working product for unfinished complexity.
  • Keep components modular and concerns clearly separated.
  • Prefer established, well-maintained libraries when they reduce overall complexity or improve reliability. Do not reimplement common functionality without a clear reason.
  • Lean on the dependencies already in the project before writing your own implementation or adding packages. Do not assume a library lacks a capability without checking its documentation and types.
  • Make architectural decisions for the long term. Do not accept a stopgap that only works for now and is meant to be replaced later.
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.
