What it does

Auth Bypass is an agent skill from NeoTheCapt/RedteamAgent. Test for authentication and authorization flaws including credential attacks, session issues, and access control bypasses

Its SKILL.md is about 1.3k 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 Authorization and RBAC, Authentication and Penetration testing. 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 Authorization and RBAC
  • Tasks that involve Authentication
  • Tasks that involve Penetration testing

Example prompts

  • “/auth-bypass”

Workflow steps

12 steps, taken from the step headings in SKILL.md.

  1. Default/Weak Credentials
  2. Brute Force (Hydra)
  3. Password Reset Flaws
  4. Session Management
  5. MFA Bypass
  6. IDOR
  7. Forced Browsing
  8. HTTP Method Tampering
  9. Path Traversal for ACL Bypass
  10. JWT Attacks
  11. OAuth/SSO Flaws
  12. Role/Privilege Manipulation

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

    No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).

    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

Auth Bypass loads about 1.3k tokens when it runs. Until then it costs about 33 tokens; SKILL.md has 384 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~33
When it runs · the whole SKILL.md, loaded when a task matches
~1.3k

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 384 words (~1,252 tokens).

“Check username enumeration: different errors for valid/invalid users, timing diffs, selective lockout.”
