At a glance

A skill your agent uses when implementing authentication (login, token issuance) or authorization (access control, permissions).

  • Implementing authentication (login
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Token issuance)
  • Authorization (access control

What it does

Auth And Authorization Patterns is an agent skill from aiming-lab/MetaClaw. Use this skill when implementing authentication (login, token issuance) or authorization (access control, permissions). Apply whenever the task involves login flows, JWT, OAuth2, session management, or RBAC.

Its SKILL.md is about 290 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 OAuth and OpenID Connect. The repository describes itself as: 🦞 Just talk to your agent — it learns and EVOLVES 🧬. The licence is MIT.

When your agent uses it

  • Implementing authentication (login
  • Token issuance)
  • Authorization (access control

Example prompts

  • “/auth-and-authorization-patterns”

What it can do on your machine

Read from SKILL.md and the folder at commit 922caf3. 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

Auth And Authorization Patterns loads about 285 tokens when it runs. Until then it costs about 60 tokens; SKILL.md has 116 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~60
When it runs · the whole SKILL.md, loaded when a task matches
~285

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.

Auth & Authorization Patterns

Authentication (who are you?):

  • Use a battle-tested library — do not roll your own crypto.
  • Hash passwords with bcrypt/argon2; never MD5/SHA1 for passwords.
  • Use short-lived JWTs (15–60 min) with refresh tokens; store refresh tokens securely.
  • Implement MFA for sensitive operations.

Authorization (what can you do?):

  • Check authorization on every request, not just at login.
  • Enforce RBAC or ABAC at the service layer, not the UI.
  • Apply principle of least privilege: grant minimal permissions needed.

OAuth2 / OIDC:

  • Use the Authorization Code flow with PKCE for user-facing apps.
  • Validate iss, aud, exp, and nonce claims on every token.

Session management:

  • Regenerate session ID after login (session fixation prevention).
  • Set HttpOnly and Secure flags on session cookies.
