LangSmith Fleet Supports Skills Feature

For agents to provide real value, they need more than simple reasoning ability—they must also have company-specific domain knowledge. If a customer support agent doesn't know the company's SLA tiers, it could make the mistake of treating all tickets the same way.

LangSmith Fleet's new Skills feature codifies this knowledge and gives it to agents. Skills serve as persistent briefing documents that agents reference when performing specific tasks, and can include content such as:

• How to classify customer support tickets according to SLA tiers
• A company's brand voice guidelines
• Step-by-step workflows for handling refund requests

Skills can be created in various ways, including:

• Generation via AI: Describe the desired functionality through chat, and AI generates it by asking questions. Existing conversations can also be converted into reusable Skills.
• Automatic generation during agent creation: Fleet automatically suggests the skills needed when creating an agent.
• Using templates: Use pre-built templates such as SEO audits and in-depth research.
• Manual authoring: Users write the details themselves.

Created Skills can be imported into local development environments via the LangSmith CLI, making them highly portable. This allows the same domain knowledge to be used instantly across various coding agents such as Claude Code, Cursor, and Codex without separate copy-pasting.

In the future, version pinning and rollback, which allow pinning or reverting to specific versions, and multi-owner permissions, which allow multiple people to jointly manage skills, will be added.
