xAI prepares Skills support for Grok to rival Claude and ChatGPT

xAI appears to be building a Custom Skills feature for Grok, which would allow users to create reusable, task-specific instruction sets directly within the Grok web interface. The feature was spotted via code references that include a feature flag, currently set to False, indicating it is still under development and not available to users. Accompanying UI mockups reveal a skill creation dialog with three fields, Name, Description, and Instruction, following the same structure now standard across competing platforms. A separate upload dialog supports importing skills via .zip, .skill, and .md files, a format convention notably similar to what Anthropic uses for Claude's own skill system, which TestingCatalog first covered in October 2025.

The timing is worth noting. xAI launched its Custom Agents feature on March 4, 2026, letting users configure up to four distinct AI agents with individual instruction sets. Skills would represent a more granular layer of customization, not full agents, but modular instruction templates that can be saved, shared, and reloaded for specific tasks like web research, content drafting, or data lookups. Power users and professionals who rely on Grok daily would benefit the most, as skills would eliminate the need to re-enter complex prompts across sessions.

This also places xAI squarely within a broader industry pattern. Anthropic introduced Claude Skills, OpenAI has been developing ChatGPT Skills, and Google recently tested Skills for Gemini Business, all within the past six months. There is no confirmed release timeline from xAI, and the feature remains dormant behind its flag, but its presence in Grok's web codebase suggests it is actively progressing toward a public rollout.
