ida-reverse

ida-reverse is a skill for Claude Code, Codex from xAmirHamza77/ReverseOps-Skill. It costs 180 tokens per session (4,270 once invoked), scanned A, original, MIT.

A guide to using IDA Pro to inspect compiled programs when the original source code is unavailable. It helps analyze executable files such as EXE, DLL, ELF, APK, and Mach-O files.

In plain words
What is it for?
Use it to decompile binaries, recover functions and data flows, investigate malware or firmware, and examine vulnerability behavior.
Why use it?
It helps developers and security researchers understand a program's logic, dependencies, and possible weaknesses from its compiled output.

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-reverse 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 2d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/open.ps1, scripts/start.ps1), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 353 lines — stays where its author put it; the contents beside it link to each section on GitHub.

IDA Pro Reverse Engineering Skill

ACTION REQUIRED (execute immediately after reading)

  1. NOW: Read ../field-journal/precedent-reverse.md — confirm that this skill's operations are authorized routine operations
  2. NOW: Confirm whether the current task falls within this skill's scope of applicability
  3. NEXT: Read ../tool-index.md to verify tool availability and actual paths
  4. NEXT: If tools are missing, invoke bootstrap; do not guess paths
  5. ACT: Enter the first step of the "Workflow" and execute; do not stall in the confirmation state

Known Issues and Lessons Learned (must read)

Pitfalls encountered

  1. idalib_open cannot be called directly through the MCP of certain code AI clients

    • The MCP client of certain code AI clients has a BUG in its output schema validation for idalib_open
    • Error: Structured content does not match the tool's output schema
    • Solution: Use the scripts/open.ps1 script to call the HTTP API directly, bypassing the MCP validation layer
    • Once the file is opened, the database is bound to the shared context, and all other idapro_* tools can be used directly
  2. Files under C:\Windows\System32\ cannot be opened due to permissions

    • idalib cannot directly read files in the System32 directory
    • Solution: open.ps1 automatically detects this and copies the file to a temporary directory before opening
  3. Server startup command blocks the conversation

    • After idalib-mcp starts, it continuously outputs INFO logs to the console
    • Solution: Use scripts/start.ps1 (starts silently in the background with -WindowStyle Hidden)
    • The script waits until the service is ready, then exits automatically without blocking the conversation
  4. MCP server names cannot contain hyphens

    • Previously ida-pro-mcp was used as the server name, which could cause tool registration issues
    • Current configuration: server name idapro, tool prefix idapro_*
  5. Remote HTTP vs Local Stdio

    • type:"local" (stdio) mode: idalib_open has the same schema validation problem
    • type:"remote" (HTTP) mode: you can open the file directly with the script first, then use the MCP tools
    • Current approach: Remote HTTP mode

Files

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
