Instructions file for CodexOpenCode

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

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

logika 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 27d 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 — 139 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Authoring & maintaining the logika skill

Agent guide for working inside this skill repository. Read it before editing SKILL.md, the README, or any plugin manifest.

Naming (Russian): the adjective for "agent / agentic" is «агентный», never «агентский».

Repository layout

This skill is packaged for Claude Code, Cursor, and OpenAI Codex (and installs as a plain skill folder for Kimi Code CLI and others). Coddy installs it from the rpa-skills catalog, which Coddy has built in.

⚠️ Golden rule: a change anywhere must be synced across the whole skill

The same facts (the skill text, its version, its description) are duplicated in several files so the skill works across platforms. Whenever you edit one, propagate the change to every place it is mirrored — in the same commit. Nothing here is allowed to drift.

1. SKILL.md lives at the repo root — single canonical copy

  • SKILL.md (repo root) — canonical. The repo itself is the skill folder: copy or symlink the whole repository into ~/.claude/skills/logika/, ~/.cursor/skills/logika/, etc.
  • Bundled assets (references/, docs/, source/) live next to it and are referenced by relative path.
  • The skill text and its references/ are in Russian (terminology per Chelpanov); keep new material in Russian too.

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.
