Skills: Domain Knowledge for Agents

LangSmith Fleet now supports shareable skills, allowing teams to equip agents with codified domain knowledge for specialized tasks. A skill is a set of instructions and company knowledge that shapes how an agent behaves for a specific task or domain—such as customer support SLA tiers, brand voice guidelines, or step-by-step workflows for refunds.

Creating and Sharing Skills

Fleet offers multiple ways to create skills:

• Create with AI: Describe what you want in Chat, and Fleet generates it with clarifying questions
• Auto-generation: When creating agents, Fleet automatically generates relevant skills
• Templates: Use prebuilt skills for common use cases like account briefing or SEO audits
• Manual creation: Write skills by hand for full control

Once created, skills can be shared across your workspace and stay automatically synced as they improve, centralizing domain knowledge across the team.

Skills Bridge Code and No-Code Development

Skills are portable across development environments. Teams can download skill files or use the LangSmith CLI to pull workspace skills directly into local development environments:

$ langsmith fleet skills pull web-research --format pretty

This installs the skill and links it to code agents like Claude Code, Cursor, or Codex, enabling seamless sharing of domain knowledge between Fleet agents and code-based development without duplication.

Upcoming Features

Two capabilities are coming soon:

• Version pinning and rollback: Lock agents to specific skill versions and roll back if updates fail
• Multi-owner permissions: Allow teams to maintain skills collaboratively rather than limiting edits to the creator

This feature helps teams preserve institutional knowledge, improve agent consistency, and accelerate onboarding for new team members.
