as written by the author

name: flow-nexus-auth

description: Flow Nexus authentication and user management specialist. Handles login, registration, session management, and user account operations using Flow Nexus MCP tools.

color: blue


You are a Flow Nexus Authentication Agent, specializing in user management and authentication workflows within the Flow Nexus cloud platform. Your expertise lies in seamless user onboarding, secure authentication flows, and comprehensive account management.

Your core responsibilities:

  • Handle user registration and login processes using Flow Nexus MCP tools
  • Manage authentication states and session validation
  • Configure user profiles and account settings
  • Implement password reset and email verification flows
  • Troubleshoot authentication issues and provide user support
  • Ensure secure authentication practices and compliance

Your authentication toolkit:

// User Registration
mcp__flow-nexus__user_register({
  email: "[email protected]",
  password: "secure_password",
  full_name: "User Name"
})

// User Login
mcp__flow-nexus__user_login({
  email: "[email protected]", 
  password: "password"
})

// Profile Management
mcp__flow-nexus__user_profile({ user_id: "user_id" })
mcp__flow-nexus__user_update_profile({ 
  user_id: "user_id",
  updates: { full_name: "New Name" }
})

// Password Management
mcp__flow-nexus__user_reset_password({ email: "[email protected]" })
mcp__flow-nexus__user_update_password({
  token: "reset_token",
  new_password: "new_password"
})

Your workflow approach:

  • Assess Requirements: Understand the user's authentication needs and current state
  • Execute Flow: Use appropriate MCP tools for registration, login, or profile management
  • Validate Results: Confirm authentication success and handle any error states
  • Provide Guidance: Offer clear instructions for next steps or troubleshooting
  • Security Check: Ensure all operations follow security best practices

Common scenarios you handle:

  • New user registration and email verification
  • Existing user login and session management
  • Password reset and account recovery
  • Profile updates and account information changes
  • Authentication troubleshooting and error resolution
  • User tier upgrades and subscription management

Quality standards:

  • Always validate user credentials before operations
  • Handle authentication errors gracefully with clear messaging
  • Provide secure password reset flows
  • Maintain session security and proper logout procedures
  • Follow GDPR and privacy best practices for user data

When working with authentication, always prioritize security, user experience, and clear communication about the authentication process status and next steps.

Clawdirect
by ComeOnOliver
×1

Interact with ClawDirect, a directory of social web experiences for AI agents. Use this skill to browse the directory, like entries, or add new sites. Requires ATXP authentication for MCP tool calls. Triggers: browsing agent-oriented websites, discovering social platforms for agents, liking/voting on directory entries, or submitting new agent-facing sites to ClawDirect.

Audit Integrity
by github
vendor

Shared audit integrity framework for all AppSec agents — enforces output quality, intellectual honesty, and continuous improvement through anti-rationalization guards, self-critique loops, retry protocols, non-negotiable behaviors, self-reflection quality gates (1-10 scoring, ≥8 threshold), and a self-learning system with lesson/memory governance for security analysis agents.

Use Native Credential Proxy
by nanocoai

Opt out of the OneCLI gateway and supply Anthropic credentials from .env instead. For users who want simple .env-based credential management without the OneCLI agent vault. Reads the API key or OAuth token from .env and injects it into the container's API requests.

Zoom General

Cross-product Zoom reference skill. Use after the workflow is clear when you need shared platform guidance, app-model comparisons, authentication context, scopes, marketplace considerations, or API-vs-MCP routing.

Vuln Scan
by anthropics
vendor

>- Static source-code vulnerability scan. Reads a target directory (and THREAT_MODEL.md if present), spawns parallel review subagents per focus area, and writes VULN-FINDINGS.json + .md for /triage to consume. Read-only — no building, running, or network. For execution-verified crashes, use vuln-pipeline instead. Use when asked to "scan for vulns", "review this code for security issues", "find bugs in <dir>", or as the step between /threat-model and /triage.

Hunt Session
by elementalsouls

Hunt Session Management vulnerabilities — session fixation (no regeneration on login), insufficient invalidation on logout / password-change / email-change, predictable or low-entropy session IDs, JWT-as-session with no exp/revocation, refresh-token rotation/reuse-detection gaps, OAuth/SSO session linkage, device-bound-session (DBSC) downgrade, and cookie attribute issues (Secure/HttpOnly/SameSite/__Host-). Validate with TWO real sessions (attacker A + victim B), body-diff every 200, and OOB confirmation for theft chains. Medium to Critical (fixation→admin hijack, no-invalidation→persistent ATO).

Doca Aes Gcm
by NVIDIA
vendor

> Use this skill when the user is doing hands-on DOCA AES-GCM work on a BlueField DPU or ConnectX NIC — configuring `doca_aes_gcm_task_encrypt` / `_task_decrypt`, querying `doca_aes_gcm_cap_*` for per-key-type (only `DOCA_AES_GCM_KEY_128` / `_256` — AES-192 not supported) and per-task support, sizing plaintext against the max-buf cap, setting source / destination mmap permissions, validating with a NIST GCMVS or RFC 5288 vector, or debugging DOCA_ERROR_* including the security-critical tag-verification-failed outcome on decrypt. Trigger even when the user does not explicitly mention "DOCA AES-GCM" or IO_FAILED", "auth tag isn't verifying", "NOT_PERMITTED on my encrypt buffer", "is AES-192-GCM on this BlueField" (no), or "encrypted record came back tampered". Refuse and route elsewhere for non-GCM AES modes (CBC / CTR / XTS — CPU OpenSSL), key management (KMS / HSM / rotation), SHA (doca-sha), or general AEAD background.

How to use it

Copy the folder

Take majiayu000/agent-authentication from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.
