[agent\_craft] Agent assumes a file or directory exists based on project conventions and attempts to edit it

Always run an existence check \(ls, test -e, or git ls-files\) before attempting to read or write a file, especially at the start of a new task.

Journey Context:
When an agent is given a task like 'add a route', it might assume a standard structure \(e.g., app/routes.py\) based on its training data, even if the project uses src/api/index.ts. If the context doesn't explicitly show the file tree, the agent will hallucinate the path. A quick ls or find grounds the agent in reality before it wastes context trying to read a non-existent file.
