Common questions
Is Hex SSH safe?
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).
Is it still maintained?
The GitHub repo last changed –, and the latest version (1.9.2) reached the registry 6 months ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.
What can I use instead?

Claude-Codex Skills
Open-source standalone agent skills, distributed as plugins for Claude Code and OpenAI Codex, help turn product ideas, code fixes, architecture reviews and deployments into scoped work with a verifiable result. Each workflow defines what to check, what it may change, and how to report evidence and remaining gaps.
Project page · Install · Full catalog
Choose a route
Choose by the result you need. Each skill works independently.
| Your task | Plugin | Result |
|---|---|---|
| Is this idea worth building? | product-discovery-suite | Opportunity assessment, requirements, or interaction design. |
| How should this system change? | architecture-suite | System map, design decision, or migration plan. |
| Is this plan ready to implement? | delivery-planning-suite | Reviewed plan, ordered work, and test strategy. |
| Fix, upgrade, simplify, or speed up this code. | implementation-suite | Scoped change with behavior and benefit checks. |
| Set up lint, type or architecture checks that enforce project rules. | implementation-suite | Verified quality gates, with project compliance reported separately. |
| What could go wrong with this delivery or codebase? | quality-assurance-suite | Evidence-backed findings or scoped acceptance tests. |
| Get this change published or deployed. | delivery-suite | Authorized publication or deployment, verified at its destination. |
| Why did this fail, or did the feature help? | operations-suite | Incident diagnosis or product outcome assessment. |
| Can I trust the instructions in this skill? | skill-maintenance-suite | Skill boundaries, consistency, and distribution review. |
| Prepare Docker containers, configuration, access control or recovery. | engineering-foundation-suite | Native technical contracts and verified changes. |
Install
For a feature or fix, start with implementation-suite. Replace it with another plugin from Choose a route for a different task.
Claude Code:
/plugin marketplace add levnikolaevich/claude-code-skills/plugin install implementation-suite@levnikolaevich-skills-marketplace /reload-plugins
Codex:
codex plugin marketplace add levnikolaevich/claude-code-skillscodex plugin add implementation-suite@levnikolaevich-skills-marketplace
Invoke a skill by its full name: /implementation-suite:ln-41-surgical-change-implementer in Claude Code or $ln-41-surgical-change-implementer in Codex, followed by your task. For example: “Fix the total calculation when an item has a discount. Preserve the current rounding rules.”
For personal defaults shared by Claude Code and Codex, use the optional user instructions template and connection guide. Personalize and merge it into your existing configuration; plugin installation does not change global instructions.
