It gives coding agents and contributors shared rules for making publishable changes without exposing private information or claiming unsupported results.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions .claude-plugin; mentions Claude Code; mentions Codex.

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

idd 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.

Public repository rules

This repository is the public surface of the IDD project. Keep every change safe to publish.

Read before changing files

  1. Read README.md, docs/status.md, and the document you will change.
  2. Use English for the main document. Add or update the matching Korean document when the meaning changes.
  3. Treat ai/idd-spec.md as a dense expert and machine-readable projection, not as permission to invent missing decisions.
  4. Treat skills/idd/SKILL.md as the canonical agent workflow. Keep Codex, Claude Code, Gemini CLI, and human documentation aligned with it.

Public boundary

  • Never add secrets, personal data, private links, internal reports, agent transcripts, or local machine details.
  • Separate verified facts, inferences, proposals, and open questions.
  • Do not claim that IDD improves speed, quality, or safety until a public evidence record supports the claim.
  • Do not present either Defend or Distill as the settled final word in a canonical three-part name.
  • This repository is licensed under the MIT License. Preserve LICENSE, its copyright notice, and the distinction between project-owned and separately identified third-party material.

Writing level

  • The introduction site uses L1.1.1: everyday language, full sentences, and an explanation before a technical term.
  • General documents use L1.1.1 through L1.2.2: plain language with a small amount of defined terminology.
  • ai/ uses L5.5.5: compact expert terminology, explicit invariants, formal states, provenance, and failure conditions.

Method rules

  • Use one isolated probe for one core uncertainty.
  • Record the intended question and safety limits before implementation.
  • Do not promote a probe without a human decision and a matching test, contract, or evaluation.
  • Require a verifier that is independent from the implementation attempt before calling a change shippable.
  • Prefer a reproducible local check for every enforced gate.
  • Keep the skill agent-neutral. Put runtime-specific metadata in .codex-plugin/, .claude-plugin/, gemini-extension.json, or skills/idd/agents/ rather than forking the workflow.

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.
