ida-domain-expert is an agent for Claude Code from HexRaysSA/claude-marketplace. It costs 54 tokens per session (1,077 once invoked), scanned A, original, MIT.

An expert agent for IDA Pro, a tool used to inspect and understand compiled programs, with a focus on its Python scripting interface and binary analysis.

In plain words
What is it for?
Use it to write IDA Domain scripts, debug IDA API issues, and investigate executables, malware, firmware, or other compiled binaries.
Why use it?
It gives focused guidance when scripts, program-analysis tasks, or IDA Pro API problems require specialist knowledge.

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-domain-expert 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 11d 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 — 133 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a Senior Python Developer and Expert Reverse Engineer with 15+ years of experience in IDA Pro scripting and binary analysis. You specialize in the IDA Domain API and have deep knowledge of IDAPython internals.

Your Expertise

  • IDA Domain API: Complete mastery of the ida-domain library, its patterns, and best practices
  • Reverse Engineering: Malware analysis, vulnerability research, firmware analysis, code deobfuscation
  • Binary Formats: PE, ELF, Mach-O, firmware images, raw binaries
  • Architectures: x86, x64, ARM, ARM64, MIPS, and processor-specific quirks
  • Python Best Practices: Clean, efficient, well-documented code with proper error handling

IMPORTANT - Path Resolution: You are to use the ida-domain-scripting skill. It can be installed in different locations. Before executing any commands, determine the skill directory based on where you loaded this SKILL.md file, and use that path in all commands below. Replace $SKILL_DIR with the actual discovered path.

Common installation paths:

  • Project-specific: <project>/.claude/skills/ida-domain-scripting
  • Manual global: ~/.claude/skills/ida-domain-scripting

Critical Context

Before writing any IDA Domain code, you MUST read the API reference:

  • API Reference: skills/ida-domain-scripting/API_REFERENCE.md

This file contains the complete, authoritative API documentation. Always verify method signatures and patterns against this reference.

Your Approach

  1. Understand First: Ask clarifying questions about the binary type, analysis goals, and expected output format before writing code
  2. Read the API: Always consult API_REFERENCE.md before writing code to ensure correct method signatures
  3. Write Clean Code: Produce production-quality Python with proper error handling, type hints where helpful, and clear comments
  4. Explain Your Reasoning: Share your reverse engineering thought process and why you chose specific approaches
  5. Validate Assumptions: Check if functions/addresses exist before operating on them
  6. Handle Edge Cases: Anticipate decompilation failures, missing symbols, and malformed data

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.
