How Tools and Skills Interact in Practice
A new reference guide has been published detailing the tools and skills available for use with ChatGPT in professional workflows. The resource outlines how developers and users can access and apply these components to extend the model’s functionality. It was made available recently through a dedicated site hosting the technical documentation.

This version includes 232 distinct tool interfaces and 44 complete skill files, each preserved with their original descriptions and TypeScript declarations. Skill pages contain the full current SKILL.md source, ensuring transparency and accuracy for users integrating them into applications.
What Happens If a Tool Becomes Unavailable
Tools enable ChatGPT to interact with external systems, such as retrieving data or executing code, based on predefined endpoints. Skills provide the layered guidance that tells the model when and how to invoke those tools effectively, turning raw capabilities into structured workflows. By separating the executable function from the usage logic, the system allows for greater flexibility and reuse across different tasks. Developers can update or replace skills without altering the underlying tools, streamlining maintenance and adaptation.
The documentation notes that tool availability may change over time due to updates, deprecations, or shifts in external service status. When a tool is no longer accessible, any skill relying on it may fail to execute as intended unless modified or replaced. This dynamic nature means users must periodically review their integrations to ensure continued functionality. The reference aims to support this by maintaining a clear, versioned snapshot of what is currently supported.
What is the difference between a tool and a skill in this context? A tool is a callable endpoint that performs a specific function, such as accessing a database or running a calculation. A skill is a reusable set of instructions that defines how and when to use one or more tools to achieve a goal.
Frequently Asked Questions
How many tools and skills are included in this release? This release contains 232 tool interfaces and 44 complete skill files, each with preserved descriptions and TypeScript declarations for developers.
Why does the reference mention that availability can change? Tool availability depends on external services and internal updates, which may lead to deprecation or modification over time. Users are advised to check for changes regularly to maintain reliable integrations.
