Skills Bring Domain Knowledge to Agents

LangSmith Fleet has introduced shareable skills—persistent briefing documents that attach domain knowledge and instructions to agents. While AI agents excel at reasoning and planning, they're most effective when equipped with company-specific knowledge like customer SLA tiers, brand voice guidelines, or business workflows. Skills codify this institutional knowledge so it's available across your team rather than locked in individual developers' heads.

Creating and Sharing Skills

Fleet offers multiple ways to create skills:

• AI-powered generation: Describe what you need, and Fleet generates the skill with clarifying questions
• Auto-generation: Fleet automatically suggests relevant skills when creating new agents
• Templates: Pre-built skills for common use cases (account briefing, SEO audits, research)
• Manual creation: Full control for teams that prefer to write skills directly

Once created, skills are shared to the workspace and automatically stay in sync as they're improved. This ensures new team members inherit institutional knowledge through the agents they use, and expertise isn't lost when someone leaves.

Portability Across Development Environments

Skills created in Fleet are portable to local development environments. Using the LangSmith CLI, developers can pull skills directly into their coding setup:

langsmith fleet skills pull web-research --format pretty

This installs the skill and links it into your agent development environment (Claude Code, Cursor, Codex, etc.), eliminating duplication and keeping domain knowledge consistent across both no-code and code-based agents.

Coming Soon

LangSmith is planning version pinning and rollback capabilities so agents can pin to specific skill versions, plus multi-owner permissions for collaborative skill maintenance. These features will be especially important as agents take on higher-stakes work where instruction quality becomes critical to reliability.
