WRITE — save the last assistant reply to a file
/write PATH
/write extracts content from the most recent assistant message and writes it to PATH inside the workspace.
Content extraction follows this rule: if the reply contains a fenced code block (~ … ~), the contents of the first such block are written. Otherwise the full reply text is written. This means you can ask the model to produce a file, inspect the reply, and then /write it without needing to copy and paste.
PATH is relative to the workspace root. Parent directories must already exist — /write will not create them. The file is created or overwritten. Symlinks are not followed. Workspace permissions are checked before writing.
Ask the model to write a Go function and save it:
harvey > Write a Go function that parses ISO 8601 dates.
harvey > /write src/dateparse.goSave a full reply (no code block) as a markdown file:
harvey > Summarize the three main design decisions in this codebase.
harvey > /write docs/design-summary.md/read FILE… — inject file contents into context /run COMMAND — run a shell command after writing /help read
