researcher-agentsmd: Instructions file for Codex

AGENTS.md

researcher-agentsmd AGENTS.md is an instructions file for Codex, OpenCode from OnTheThirdDay/researcher-agentsmd. It costs 2,866 tokens per session, scanned A, original, MIT.

Repository instructions for running research so that results can be checked and reproduced. They define result statuses and require saved evidence for research claims.

In plain words
What is it for?
Use them when running experiments, recording outputs, checking repeatability, and deciding whether a result can support a research claim.
Why use it?
They reduce the risk of treating an attractive but unverified result as reliable evidence. They also make it possible for another person to reconstruct what happened.

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

researcher-agentsmd 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.

AGENTS.md — Research Execution Rules

These rules apply to any agent working in this repository. They are meant to protect research validity, reproducibility, and auditability.

1. Core Principle

A result is not accepted because it looks good.

A result may support a research claim only when it is traceable, reproducible, audited, and robust enough for the claim being made.

If another agent cannot reconstruct how a result was produced from saved artifacts, then that result cannot support a research claim.

2. Result Status

Every reported result must be assigned one status:

  • EXPLORATORY: informal observation; useful for direction only.
  • DIAGNOSTIC: useful for debugging or understanding behavior; not claim-supporting.
  • EXISTENCE_PROOF: shows something happened once; not evidence of a stable recipe.
  • SINGLE_RUN: produced by one traceable run; not yet robust.
  • REPLICATED: reproduced across appropriate seeds, splits, or equivalent robustness checks.
  • ACCEPTED: audited replicated result that may support a stated claim.
  • LOCKED: accepted result written into a consolidated report; changes require correction or retraction.
  • FAILED: did not meet its predeclared success criteria.
  • RETRACTED: previously stated claim invalidated by later evidence.
  • PROVENANCE_ORPHAN: artifact exists, but its generation path is incomplete or inconsistent.

Do not present EXPLORATORY, DIAGNOSTIC, EXISTENCE_PROOF, or PROVENANCE_ORPHAN results as accepted claims.

3. Forbidden Actions

Agents must not:

  • produce claim-supporting model artifacts from inline commands, notebooks, REPL sessions, pasted scripts, or unsaved temporary code;
  • overwrite existing model artifacts or reuse an old output directory for a new run;
  • copy a model artifact and describe the copy as a fresh training run;
  • silently change metrics, data splits, training objectives, or model-selection rules;
  • use test data or answer labels to select a model artifact unless the claim explicitly permits it;
  • expand the experiment scope beyond the approved plan;
  • describe a single successful run as stable or general;
  • hide failed runs, failed seeds, or negative controls.

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.
