New Feature: Skill Reflection—Enabling Continuous Skill Improvement Through Feedback

On October 15, 2026, Glean introducedSkill Reflection. It organizes reusable corrections, omitted steps, and preference changes made while using the skill into improvement suggestions, which users can preview and update the skill only after explicitly approving them. A one-time request does not have to become a fixed rule for all subsequent tasks.

This capability separates “gathering experience” from “applying changes”: the system looks for relevant signals during the session in which the skill is invoked and evaluates potential improvements after the session ends; the accumulated suggestions can be prompted by the assistant or viewed proactively by the user. Ultimately, the user decides whether to rewrite the skill.

Suitable for:Reusable work templates such as customer service upgrade guidelines, product decision documents, and knowledge base articles. Teams can start by selecting a low-risk skill, identify which changes are worth retaining long-term, approve the implementation, and then review the new version against past typical tasks.

Recommendations for Use:Distinguish between one-time customer requests and the team’s general standards, designate a skills maintainer, and retain audit records. While the official documentation describes the feature’s mechanisms, companies should still verify them in light of their own data access permissions, operational standards, and the actual scope of account access; one cannot assume that task accuracy will necessarily improve simply because the system is “trainable.”
