ida_rpc: Instructions file for Codex

AGENTS.md

ida_rpc AGENTS.md is an instructions file for Codex, OpenCode from bkerler/ida_rpc. It costs 3,889 tokens per session, scanned A, original, MIT.

A set of project instructions for developing ida-rpc, a plugin that lets tools control IDA Pro, a program for examining compiled software and binaries.

In plain words
What is it for?
Use it to open binary files, inspect functions and project metadata, decompile code, trace references, rename functions, add comments, and save analysis results.
Why use it?
It gives agents a consistent way to inspect and reverse-engineer programs through ida-rpc instead of relying on screen scraping or improvised scripts.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions AGENTS.md.

This is bkerler/ida_rpc's own configuration. It tells Codex and OpenCode how to work on ida_rpc 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 ida_rpc configures →

Not installable: its command points at a path on the author’s own machine, so it runs nowhere else. The line is /home/bjk/bin/ida-pro-9.4.

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

ida_rpc 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 1mo 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 — ida-rpc

Agent-focused guidance for developing and extending the IDA Pro RPC plugin.

Automatic Reverse Engineering Usage

When reversing binaries with IDA Pro, prefer ida-rpc before screen scraping, manual GUI steps, or ad hoc IDAPython scripts.

Use these stable agent probes first:

ida-rpc capabilities
ida-rpc find-project <binary-or-idb>
ida-rpc list-loaders <binary>

Then use:

ida-rpc open <binary-or-idb> --arch <arch> --detach
ida-rpc open <raw.bin> --arch arm --base 0x8000 --loader raw --detach
ida-rpc open <loader.bin> --arch arm --loader miniloader --detach
ida-rpc status --project <idb>
ida-rpc metadata --project <idb>
ida-rpc functions --project <idb> --limit 50
ida-rpc decompile <function-or-address> --project <idb>
ida-rpc xrefs-to <target> --project <idb>
ida-rpc xrefs-from <target> --project <idb>
ida-rpc rename-function <target> <new_name> --project <idb>
ida-rpc set-comment <address> <comment> --project <idb>
ida-rpc save --project <idb>

All automation commands print human-readable text to stdout by default. Pass --json (before the subcommand) or set IDA_RPC_JSON=1 for JSON output. Treat {"ok": false, ...} (JSON mode) or Error: <error>: <message> (human mode) as a recoverable tool error. Set IDA_RPC_DEBUG=1 only when a traceback is needed.

RPC queries should always be run outside the sandbox.

Project Overview

ida-rpc is a JSON-RPC daemon that runs inside IDA Pro (as a plugin) and exposes reverse-engineering capabilities over a Unix domain socket. It is wire-format compatible with ghidra-rpc.

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.
