reverse-engineer-anything

reverse-engineer-anything is a skill for Cursor from roedyrustam/vibes-plug. It costs 83 tokens per session (9,341 once invoked), scanned A, original, MIT.

A workflow for examining shipped software such as native binaries, firmware, packaged applications, and live websites with REA. Reverse engineering means learning how a shipped program works from its files or observed behavior, rather than only from source code.

In plain words
What is it for?
Use it to compare software versions, inspect compiled or packaged code, decompile programs, investigate firmware, or build an agent environment from a live website or capture.
Why use it?
It helps investigate behavior that source code does not establish while requiring claims to be tied to runtime or shipped-artifact evidence.

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

reverse-engineer-anything 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 today.

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

REA

Use REA when a claim depends on a shipped binary or package, decompilation, requested runtime evidence, or comparison with behavior not established by available source. For ordinary analysis of a complete source repository, use normal repository tools and do not run REA readiness or provider commands.

Connect only when needed

Installing this skill supplies instructions; it does not register the REA MCP server, install analysis engines, or add tools to an already-running agent.

If REA tools are available and their registration is not known to be stale, proceed directly to the target. Do not run diagnostics or setup before every investigation. Use the connected server's actual tool list and input schemas; a skill installed from repository main may describe capabilities absent from an older npm release. Keep complete inline Evidence when that server does not advertise retained references.

If tools are absent, a call is blocked by the client, or a required provider is unavailable, read connection and recovery. Diagnose the observed blocker, continue useful supported work, and resume the original task after repair. Client approval, shell PATH, registration and engine availability have different remedies; avoid repeating setup for all of them. If the host times out without a REA result, do not repeat the unchanged call or assume work stopped. Read the recovery guide's deadline distinction before retrying. If the MCP connection drops, retry that call once only when it is safe to repeat or known not to have started. If it may already have changed the target, or it fails again, tell the user and ask them to restart the MCP client. If REA could not start its connection, retry once, then tell the user and ask them to restart the MCP client. Do not retry a startup failure that returns the same unchanged result. Run rea doctor when REA could not start or tools stay missing after that restart. For cleanup_incomplete, a retryable capacity limit, or configuration_invalid, follow the recovery guide's ladder before asking for a restart. Read that guide before a second repair attempt.

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.
