renef-skills: Instructions file for Codex

AGENTS.md

renef-skills AGENTS.md is an instructions file for Codex, OpenCode from vichhka-git/renef-skills. It costs 561 tokens per session, scanned A, original, Apache-2.0.

Repository instructions for AI agents working with renef, an Android ARM64 tool for inspecting and changing running apps through scripts. They explain which manual and reference files to read for different tasks.

In plain words
What is it for?
Use them when writing or fixing renef scripts, including tasks involving function hooks, memory, Java integration, system calls, or translating scripts from other tools.
Why use it?
They help an agent find the right renef documentation without loading every reference file at once.

Instructions file for CodexOpenCode

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

This is vichhka-git/renef-skills's own configuration. It tells Codex and OpenCode how to work on renef-skills 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 renef-skills 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

renef-skills 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.

How it starts

The opening of the file, as written. The whole thing — 44 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md — orientation for AI coding agents

This repository is not an application — it is a portable Agent Skill that teaches an AI agent to operate renef (a dynamic-instrumentation engine for Android ARM64: hook native/Java functions, scan/patch memory, trace syscalls, bypass SSL pinning / root detection via Lua 5.4 scripts).

What to read

The skill itself is the source of truth:

  • skills/renef/SKILL.md — operator's manual: syntax contract, self-lint, task → playbook.
  • skills/renef/references/ — load on demand:
    • lua-api.md — full Lua API (Module, Memory, hook, Jni, Java, Thread, File, Syscall, OS, KCov)
    • cli.md — CLI commands, flags, connect modes, build/deploy
    • from-other-tools.md — translate Frida JS and GameGuardian (gg.*) / game-hacking Lua → renef
    • recipes.md — copy-paste scripts (SSL/root bypass, tracing, memory cheats, CTF)
    • gotchas.md — pitfalls, doc/runtime discrepancies, troubleshooting

If a user asks you to write or fix a renef script, read skills/renef/SKILL.md first, then pull the relevant reference file. The format is progressive-disclosure by design — do not load all references at once.

Format

SKILL.md uses the standard Agent Skills format (YAML frontmatter with name + description). This is consumed natively by Claude Code and OpenCode, and the content is plain Markdown reusable by any agent. See README.md → Install for per-agent setup.

Installing this skill for the user

When a user wants the renef capability available in their own projects, copy the skill directory into a location their agent scans (one copy can serve multiple agents):

# Works for BOTH Claude Code and OpenCode (both read .claude/skills):
mkdir -p ~/.claude/skills && cp -r skills/renef ~/.claude/skills/renef   # global
# or, per-project:
mkdir -p .claude/skills && cp -r skills/renef .claude/skills/renef

This repo ships documentation/instructions only — no renef binaries. renef itself (server/agent) is installed separately on the Android device; see skills/renef/references/cli.md.

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.
