 # Gardener tasks
 
 Gardener runs AI maintenance tasks on this repository from GitHub Actions. Each task is one
 Markdown file: YAML frontmatter says when it runs, what the model may read, and exactly which
 changes it may make; the body is the model's instructions. A planning job runs the model with only
-the declared **tools** and lets it propose only the declared **effects**. A separate job then applies
-those proposals. Nothing outside the declaration is possible, whatever the instructions say.
