cortex-ai-skills

Cortex AI Skills is a personal “skills” library intended to be installed into AI coding assistant platforms (e.g., Claude Code) via a plugin/skill marketplace, exposing multiple skills under slash commands (e.g., /<skill-name>) and providing an npx-based way to add/install skills from the repository.

Secret Handling

No security architecture is described in the provided README. Installation and skill execution likely involve running code/commands inside the assistant environment; review the actual skill contents before use in sensitive contexts. No mention of secret management, permissions, or safe execution boundaries.

Error Recovery

Best When

You want reusable, assistant-specific skills (slash-command workflows) rather than a general-purpose web API.

Avoid When

You require a clear REST/GraphQL/MCP interface, documented auth model, and explicit operational controls (rate limits, retries, idempotency) from this repository.

Use Cases

• Enable prebuilt workflow/command skills in Claude Code (and potentially other assistant environments) for coding assistance
• Quickly install one or many skills from a shared repository using the npx skills tooling
• Reuse and adapt personal assistant skills using a standardized skill-creator format

Not For

• Production-grade API integration requiring guaranteed HTTP endpoints, SDKs, and documented error contracts
• Use as a secure credentialed service for sensitive actions without reviewing the underlying skill implementations
• Teams needing formal compliance guarantees (not documented in the provided README)

Authentication

OAuth: No Scopes: No

No authentication mechanisms are described in the provided README; installation appears to be marketplace/npx based and assistant-managed.

Known Gotchas

⚠ The repository interface is skill/plugin-oriented rather than an API; agent execution depends on the host assistant (e.g., Claude Code) and the actual skill definitions, which are not included in the provided README.
⚠ No explicit guidance is provided for how to handle failures, retries, or partial installs beyond generic installation commands.
