# Officer capabilities The file-based store Officer reads agent items from. This repository holds the ones the **platform ships**; everything else in this directory is yours. ``` affordances/officer/core/ ← shipped here skills/ tools/ tasks/ processes/ extensions/ agents/ ``` Those six directories are created by the platform at boot and are where you and your agents author items. They are deliberately **not tracked here** — your work is not ours to version. `extensions/tool-loader` is written by the platform from its own source and will reappear if you delete it. ## Affordances An affordance is what the surface on the other end of the conversation offers the agent: what the client will render, accept or ignore. Not what the agent can do — what it will get away with. The platform compiles every affordance into one block and appends it to each agent session, so an agent knows things it could not otherwise discover from the filesystem. `plugins/CLAUDE.md` in the platform is the authority on the format and on what belongs in one. Layout is `//`, with `core` in the plugin slot for the platform's own. A plugin ships its own `affordances/` directory and installing it copies them in. ## Updating `git pull`, or press **Update all** on the platform's marketplace screen, which updates this alongside every installed plugin. Your own untracked items are unaffected by either.
