What it does
User Enumeration is an agent skill from NeoTheCapt/RedteamAgent. Discover any interface (HTTP, WebSocket, GraphQL, gRPC, or other) that distinguishes between existing and non-existing users through any observable difference
Its SKILL.md is about 2.9k 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 Backend & APIs, covering Realtime and WebSockets, gRPC and Protobuf and GraphQL. It works with gRPC and GraphQL. The repository describes itself as: An AI red-team agent for authorized labs and web app pentesting workflows. Turns Claude Code / OpenCode / Codex into a structured recon → test → exploit → report workflow, with…
When your agent uses it
- Tasks that involve Realtime and WebSockets
- Tasks that involve gRPC and Protobuf
- Tasks that involve GraphQL
Example prompts
- “/user-enumeration”
Requirements
- Python 3
Workflow steps
12 steps, taken from the step headings in SKILL.md.
- Identify Enumeration Surfaces
- Login Form Enumeration
- Registration Form Enumeration
- Password Reset Enumeration
- Explicit Check Endpoints
- Timing-Based Enumeration
- Brute-Force Enumeration (after confirming enumerable endpoint)
- OTP / Verification Code Abuse
- WebSocket Enumeration
- GraphQL Enumeration
- SSO / OAuth Flow Enumeration

What it can do on your machine
Read from SKILL.md and the folder at commit 2e60476. 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
Shell commands in SKILL.md call:
python3
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
User Enumeration loads about 2.9k tokens when it runs. Until then it costs about 44 tokens; SKILL.md has 600 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.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 600 words (~2,869 tokens).
“User enumeration is NOT limited to HTTP APIs. ANY interface that accepts a user identifier (username, email, phone, ID) and produces ANY observable difference between existing and non-existing users is an enumeration vector. This includes:”
- name
- user-enumeration
- origin
- RedteamOpencode

When should I use User Enumeration?
User Enumeration fits situations like: tasks that involve Realtime and WebSockets; tasks that involve gRPC and Protobuf; tasks that involve GraphQL.
How do I install User Enumeration in Claude Code?
Run `npx skills add NeoTheCapt/RedteamAgent --skill user-enumeration -a claude-code`. Or copy the skill folder (agent/skills/user-enumeration in NeoTheCapt/RedteamAgent) into .claude/skills/user-enumeration in your project. Claude Code loads it when a task matches its description.
How do I install User Enumeration in Codex?
Run `npx skills add NeoTheCapt/RedteamAgent --skill user-enumeration -a codex`. Or copy the skill folder (agent/skills/user-enumeration in NeoTheCapt/RedteamAgent) into .agents/skills/user-enumeration in your project. Codex loads it when a task matches its description.
Can I use User Enumeration in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add NeoTheCapt/RedteamAgent --skill user-enumeration -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/user-enumeration, .gemini/skills/user-enumeration, .github/skills/user-enumeration and .opencode/skills/user-enumeration in your project.
What does User Enumeration need to run?
Going by SKILL.md and its folder, User Enumeration needs the command-line tools its instructions call (python3). Our summary lists: Python 3.
Does User Enumeration access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
