UVVR: Instructions file for Codex

AGENTS.md

UVVR AGENTS.md is an instructions file for Codex, OpenCode from divo12/UVVR. It costs 1,722 tokens per session, scanned A, original, MIT.

Repository instructions for UVVR, a project that designs evaluations for AI systems when some results cannot be directly checked. They define the project’s terminology, boundaries, workflow, and implementation rules.

In plain words
What is it for?
Use them when changing UVVR’s code, evaluation-design skill, research artifacts, or repository structure.
Why use it?
They help coding agents avoid treating uncertain scores as proven truth and keep automated checks separate from human judgment.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: reads ~/.codex paths; mentions AGENTS.md; mentions Codex.

This is divo12/UVVR's own configuration. It tells Codex and OpenCode how to work on UVVR 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 UVVR 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

UVVR 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 2mo 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.

UVVR Engineering Rules

These instructions apply to coding agents working anywhere in this repository.

Product boundaries

  • This repository develops an instruction-first Codex skill for designing defensible evals for AI systems whose work is partly unverifiable.
  • UVVR must distinguish deterministic or executable verification, grounded or anchored verification, calibrated semantic proxies, and human or delayed-outcome judgment.
  • Preserve the V4–V0 terminology defined in the research artifacts. Never implement behavior that labels an LLM score, rubric score, majority vote, or learned reward model as ground truth.
  • Preserve an explicit unverifiable remainder. Do not force every criterion into an automated score.
  • Keep intended outcomes separate from forbidden outcomes. Safety, permission, privacy, and evidence-integrity failures are gates.
  • The first product wedge is eval design for research agents. Customer support is the first out-of-domain contrast, not a second MVP domain.
  • The first milestone is one instruction-only skill plus real examples and behavioral evidence. Do not add hooks, persistent modes, MCP, dashboards, hosted services, or multi-host adapters without an observed need.

Required coding workflow

  1. Restate the requested repository change and explicit non-goals.
  2. Inspect AGENTS.md, the relevant files, referenced artifacts, and every consumer before editing.
  3. Draw the smallest affected file flow and identify trust boundaries or hidden evaluation assets.
  4. Define observable behavior, inputs, outputs, error cases, and file ownership before implementation.
  5. For behavior changes, add or update the smallest test or realistic fixture that would fail without the change.
  6. Implement the smallest change that makes the observable requirement pass.
  7. Refactor only demonstrated duplication or measured complexity in the changed path.
  8. Run every applicable validation command and inspect generated or modified artifacts.
  9. Review the final diff for scope creep, duplicated guidance, leaked holdouts, secrets, and unrelated changes.
  10. Report exact local verification evidence. Never describe a local command as CI evidence.

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.

UVVR AGENTS.md is an instructions file published in the GitHub repository divo12/UVVR (2 stars, last pushed 2mo ago), licensed MIT. It adds 1,722 tokens to every session, about $0.0069 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
