Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00046 | $0.02721 |
| Opus 5 | $0.00023 | $0.01360 |
| Sonnet 5 | $0.00009 | $0.00544 |
| Haiku 4.5 | $0.00005 | $0.00272 |
Grade A, and why
auth scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Auth — Authentication & Authorization
Activate When
- User invokes
/godmode:auth - User says "authentication", "login flow", "OAuth setup", "JWT tokens", "session management"
- User says "MFA", "two-factor", "passwordless", "social login", "SSO"
- Building features that require user identity or access control
- Integrating with identity providers (Auth0, Okta, Cognito, Keycloak, Firebase Auth)
- Pre-ship check when
/godmode:securedetects authentication weaknesses - Designing API authentication for
/godmode:apiendpoints
Workflow
Step 1: Identity Requirements Discovery
Determine the authentication and authorization needs:
IDENTITY REQUIREMENTS:
Application type: <SPA | SSR | Mobile | API-only | Microservices | Hybrid>
User populations:
Step 2: Auth Strategy Selection
Select and design the authentication strategy based on requirements:
Strategy: JWT (JSON Web Tokens)
For stateless API authentication:
JWT DESIGN:
Algorithm: RS256 (asymmetric) | ES256 (ECDSA) | HS256 (symmetric, single-service only)
Access token:
Strategy: OAuth 2.0 / OpenID Connect
For delegated authentication and third-party integration:
OAUTH2 / OIDC DESIGN:
Grant types:
- [ ] Authorization Code + PKCE (SPAs, mobile, server apps — RECOMMENDED)
Strategy: SAML 2.0
For enterprise SSO federation:
SAML DESIGN:
Role: Service Provider (SP)
Identity Provider: <Okta | Azure AD | ADFS | OneLogin | custom>
API KEY DESIGN: Format: Prefixed key (e.g., sk_live_abc123, pk_test_xyz789) Prefix: Environment indicator (live/test) + type (secret/publishable) Entropy: 32+ bytes of cryptographic random, base62 encoded Length: 40-64 characters total
Storage: Server-side: Store HASH only (SHA-256 or bcrypt), never plaintext Display: Show only last 4 characters after creation (sk_live_...a1b2) Lookup: Use prefix + hash index for efficient lookup
Lifecycle: Creation: User generates via dashboard/API, shown ONCE Rotation: Support key rotation with overlap period (old key valid for 24h) Revocation: Immediate revocation via dashboard/API Expiry: Optional expiry date, default no expiry with activity monitoring
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

auth is a skill published in the GitHub repository arbazkhan971/godmode (26 stars, last pushed 7d ago), licensed MIT. It adds 46 tokens to every session and 2,721 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
