Authentication

What it does

When your agent uses it

• Tasks that involve Authentication
• Tasks that involve OAuth and OpenID Connect

Example prompts

• “/authentication”

Requirements

• Python 3

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

1. 1Analyze auth implementation (forms, tokens, 2FA, CAPTCHA)
2. 2Test bypass vectors per technique type
3. 3Use Playwright MCP with human-like behavior (typing 80-200ms, random pauses)
4. 4Capture evidence (screenshots, network logs, tokens)
5. 5Document findings with PoC scripts

What it can do on your machine

Read from SKILL.md and the folder at commit 95fdc12. 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

  Ships script files (Python, from the files we listed), which the agent can run.

  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

Authentication loads about 610 tokens when it runs. Until then it costs about 40 tokens; SKILL.md has 188 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~40

When it runs · the whole SKILL.md, loaded when a task matches

~610

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

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.
