What it does
Security Usernames is an agent skill from Ch1nfo/RiftX. Top username lists for enumeration: common usernames, default credentials, names. Curated essentials for testing.
Its SKILL.md is about 230 tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including reference files.
It sits in Security. The repository describes itself as: Pentest anything you want. The licence is MIT.
When your agent uses it
- Security work in your project
Example prompts
- “/security-usernames”
What it can do on your machine
Read from SKILL.md and the folder at commit 1e3369f. 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
Links to these hosts (documentation or services it may open):
github.com
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
Security Usernames loads about 226 tokens when it runs, and up to ~21k if it reads all its reference files. Until then it costs about 33 tokens; SKILL.md has 61 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.
