# Skills - Docs by LangChain

## Retrieval answer

LangChain’s Deep Agents documentation describes versioned controls for loading and operating agent skills.

LangChain’s Deep Agents documentation describes versioned controls for loading and operating agent skills. A skill is a directory with a `SKILL.md` file containing YAML frontmatter and instructions, with optional scripts, references, templates, and other resources. Deep Agents follows the Agent Skills specification.

Tool binding is documented for `deepagents>=0.7.22`. A skill can list space-separated tool names in `metadata.include_tools`; those tools remain gated until the agent reads that skill’s `SKILL.md`. Tools are attached through `SkillsMiddleware`, and a resolver can map names to tools at runtime, including per-user tools.

Pinned skills are documented for `>=0.7.23`: names supplied in `pinned_skills` cause the corresponding `SKILL.md` content, excluding frontmatter, to be appended as tagged messages before the next model call, and make that skill’s tools available. Reload support is documented for `>=0.7.16`: setting `skills_metadata` to `None` in run input or through `update_state` rescans skills on the next run; a changed set invalidates the prompt cache.

The documentation does not provide a release date, benchmark results, or evidence that these controls improve skill selection or task success rates.
