What it does
Rea Tool Design is an agent skill from morluto/rea. Design or change REA investigation tools, CLI/MCP contracts, provider capabilities, and Evidence semantics.
Its SKILL.md is about 240 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Security, covering Reverse engineering and malware and MCP servers. It works with Model Context Protocol and Ghidra. The repository describes itself as: Reverse engineer anything with agents, from app behavior down to native binaries. The licence is MIT.

- Tasks that involve Reverse engineering and malware
- Tasks that involve MCP servers
Example prompts
- “/rea-tool-design”
What it can do on your machine
Read from SKILL.md and the folder at commit 7296f2b. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Rea Tool Design loads about 239 tokens when it runs. Until then it costs about 31 tokens; SKILL.md has 91 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

REA tool design
Use the tool-design guide for tool boundaries, contract semantics, provider ownership, and discoverability. Inspect the current contract and nearest existing tool relevant to the analyst question; source, documentation, and live catalogs may describe different versions.
For a design request, return the proposed boundary, input/result shape, Evidence semantics, nearest alternative, and verification approach. Implement when requested, preserving the user's scope and existing authorization.
For implementation or verification, consult testing for the affected consumer and provider lanes, and contributing for generated-file ownership. Read provider/workflow guides only as the task requires.
